Summarize the following court judgment. os. 246 of 1956 and 2 of 1959 (Under Article 32 of the Constitution of India for enforcement of Fundamental Rights) with C. As. 126 to 128 of 1958. August 16	 17. N. C. Chatterjee	 with N. C. Chakravarti	 Dipti Bose and section C. Mazumdar for the petitioners in Petition No. 246 of 1956 and with P. Chaudhuri	 D. N. Mukherji and B. N. Ghose	 for the appellants in C. As. 126 128 of Taxation (on goods carried by road and inland waterways) Act	 contravenes article 301 of the Constitution. Article 301 means freedom from all restrictions including tax laws. Articles 245 and 246 are subject to article 301. It is wrong to say that taxation is outside the scope of article 301. Article 304(a) itself contemplates 'the imposition of tax. Article 304(b) may also refer to tax in certain circumstances	 in cases other than those covered by article 304(a). In enacting article 301 the Constituent Assembly rejected section 297 of the Government of India Act	 1935	 and deliberately adopted the Australian section 92. Movement is an essential ingredient of trade and commerce and there must be no fetter on it; any taxation would be a fetter. Taxation is not outside the ambit of article Bom. 680	 683. What is commerce is brought out in the following decisions : ; 	 68; ; 	 578 ; ; ; 1936 A.C. 573	 627 A.I.R. 1954 Raj. 217. B. Sen and section N. Mukherjee	 for the petitioners in Petn. No. 2/59. Article 301 sets out the general freedom and article 302 the restrictions that can be placed on this freedom. Non discrimination is one of the aspects of the freedom in article 301. Article 306 as it stood before its deletion	 spoke of taxation or duty on import or export of goods between States. It postulated 'taxes ' in article 301 ; but for the non obstante clause it would have been affected by article 301. The Supreme Court has discussed the scope of article 301 in ; 	 1079	 1081	 1088. The decision Of Chagla	 C. J.	 in I.L.R. regarding scope of article 301 was not reversed by the Supreme Court. B. K. P. Sinha and A. G. Ratnaparkhi. With regard to the scope of article 301 reference is invited to the decision in A.I.R. 1954 Hyd. 207	 A.I.R. 1958 M.P. 33	 A.I.R. 1956 M.B.

Lahiri	 Advocate General of Assam and Naunit 812 Lal	 for the respondents in Petition No. 246 of 1956 and Civil Appeals Nos. 126 128 of 1958 and Petition No. 2 of 1959	 and with T. M. Sen	 for the Intervener	 Attorney General of India. Power to tax is an incident of sovereignty. The Power is divided between the Union and the States. Part XII of the Constitution deals with taxation several aspects of it. All restrictions on the powers to tax are contained in Part XII which is self contained. Part XII1 deals with something else. article 301 deals with freedom of inter State as well as intra state trade and is different from section 92 of the Australian Constitution. In Article 301 freedom of trade only means freedom from trade barriers it does not mean freedom from taxation. Taxation simpliciter was not within the terms of article 301. Taxation is not a restriction within the meaning of Part XIII. Article 302 uses the words " in the public interest ". If the restrictions contemplated therein included tax	 then every tax will have to be justified to be in the public interest. Restrictions do not include taxing measures	 otherwise there will be a power of judicial review in respect of all such taxing measures. Cooley 's Consti tutional Limitations	 8th Edition	 Vol. II	 p. 986 988. Taxation is a peculiarly legislative activity. It is likely that if the Constitution makers wanted to put a bar on the taxation power	 it would have been placed 'in Part XII and not left to be inferred from article 301 ; ; 	 136 137: The word " restriction " is very inapt to describe taxation. Apart from Part III all restrictions must be found in Part XIII so far as taxation is concerned. Article 301 does not start with the words " notwithstanding anything in this Constitution " because it is concerned only with a small sphere of freedom of trade and commerce and not with taxation. Restriction in these Articles means restriction on movement. The result of holding otherwise would be that even for intrastate taxes the States will have to go to the President and the legislation will be subject to judicial review. If Part III as well as article 301 apply to taxing measures	 the question will arise which test would 813 the Court apply " reasonable in the interest of the general public " as envisaged by Part III or " in the interest of the public " envisaged by article 302. This indicates that neither Part III nor article 301 applies to taxing measures. Article 303 deals with preference and discrimination between one State and another. It is restricted to legislation with respect to the entries regarding trade and commerce within the State	 like entry 26	 list II and the entries 33 and 42 of list 111. Nothing in article 303 indicates that the freedom there includes freedom from taxation. Article 304(a) deals with discrimination and not with taxation simpliciter. It lays no restriction on the State taxing goods in its own territory: Article 304(a) cannot be interpreted as throwing any light on the scope of article 301. Section 297 of the Government of India Act	 1935	 was the predecessor of article 304. Article 304(a) assumes that there is an existing tax on goods which is not levied under 304(a). There is an intermediate position also. Article 301 should be restricted to legislation which is directly with respect to trade and commerce and not to legislation	 which is in pith and substance not with respect to trade but only incidentally or indirectly affects trade and commerce. The Assam Act passed under entry 56 is not a legislation with respect to trade and commerce. Mahabir Prasad	 Advocate General for the State of Bihar	 B. K. Saran and K. L. Mehta for the Intervener	 State of Bihar. Article 301 merely concerns itself with the restrictions on the free flow of trade and commerce. It deals with policy of protection. Article 302 also contemplates movement and passage of goods. Restriction does not as a rule imply taxation. If taxation is imposed with a view to restrict goods passing from one State to another	 it will become a restriction under article 301. Article 304(a) permits tax on entry of goods equal to the tax on such goods which are in the State. Octroi may be hit by article 301 if it is not saved by other provisions. It 104 814 is a restriction within article 301 when it obstructs the movement of trade. section M. Sikri	 Advocate General for the State of Punjab	 N. section Bindra and T. M. Sen for the Intervener	 the State of Punjab. It is impossible to determine whether a particular tax places reasonable restrictions and whether it is in the public interest. Article 301 is concerned with the right of passage generally with respect to trade and commerce and article 19(1)(g) with the right of an individual: 1955 P.L.R. Raj. 794; A.I.R. 1960 Andhra 234. Article 302 assumes legislation of Parliament under the entries relating to trade and commerce. R. Ganapathi Iyer and T. M. Sen	 for Intervener No. 3	 the State of Madras adopted the submissions made by the Attorney General. G. C. Kasliwal	 Advocate General for the State of Rajasthan and T. M. Sen for the Intervener	 the State of Rajasthan adopted the submissions made by the Attorney General. G. C. Mathur and C. P. Lal	 for the Intervener No. 6	 the State of Uttar Pradesh	 adopted the submissions made by the Attorney General. N. C. Chatterjee in reply. Article 301 is an over. riding provision over all other provisions. It is much wider than section 297 of the Government of India Act. It applies to all pecuniary burdens and commands that trade shall be free from all pecuniary burdens: 22 C.L.R. 566; 1936 A.C. 573	 629 630. 1960. September 26. The Judgment of Sinha	 C. J.	 was delivered by Sinha	 C. J. The judgment of Gajendragadkar	 Wanchoo and Das Gupta	 JJ.	 was delivered by Gajendragadkar	 J. and Shah	 J.	 delivered his own judgment. SINHA C. J. These appeals on certificates granted under article 132 of the Constitution by the High Court of Judicature in Assam and Writ Petitions under article 32 of the Constitution impugn the constitutionality of the Assam Taxation (on Goods Carried by Roads or Inland Waterways) Act	 (Assam Act XIII 815 of 1954)	 which hereinafter will be referred to as the Act. The appellants moved the High Court under article 226 of the Constitution challenging the validity of the Act. The High Court by its judgment and order dated June 6	 1955	 dismissed the writ petitions. Thereupon	 the appellants obtained the certificates that the cases involved substantial questions of law as to the interpretation of the Constitution. The petitions under article 32 of the Constitution were moved in this Court for the same purpose of challenging the vires of the Act. The appellants and the petitioners will 	 in the course of this judgment	 be referred to	 for the sake of convenience	 as the appellants. The State of Assam	 the Commissioner of Taxes	 appointed under section 6 of the Act	 and the Superintendent of Taxes are the respondents to the appeals and the writ petitions. It appears that the appellants are growers of tea in West Bengal or in Assam and carry their tea to the market in Calcutta from where the tea is sold for consumption in the country or is exported for sale out of the country. The sale of tea inside Assam bears a very small proportion to the tea produced and manufactured by the appellants. Thus the bulk of tea produced and manufactured is carried out of Assam	 either for internal consumption in India or for export abroad. Besides the tea carried by rail	 a large quantity of tea is carried by road or by inland waterways from Assam to Bengal and in some of these cases	 from one part of West Bengal to another part of the same State through inland waterways	 only a few miles of which pass through the territory of the State of Assam. The Assam Legislature passed the Act which received the assent of the Governor of Assam on April 9	 1954	 and came into force on and from June 1	 1954. The purpose of the Act is to levy taxes on certain goods carried by road or inland waterways in the State of Assam. On June 30	 1954	 the second respondent	 the Commissioner of Taxes	 Assam	 in exercise of the powers conferred upon him by subs. (3) of section 7 of the Act		 published a notification in the Assam Government Gazette bearing date June 21	 816 1954	 by which he notified for general information that the return under the aforesaid Act and the rules made thereunder for the period commencing June 1	 1954 to September 30	 1954	 should be furnished by October 30	 1954. The said notification also demanded the furnishing of quarterly returns before January 30	 1955 and April 36	 1955	 for the quarters ending December 31	 1954 and March 31	 1955	 respectively. The appellants in some of the cases	 in pursuance of demand notices	 submitted returns to the third respondent	 the Superintendent of Taxes	 in the prescribed form in respect of tea despatched and carried up to September 30	 1954	 under protest. They also paid the tax demanded under protest. The appellants moved the High Court of Judicature in Assam under article 226 of the Constitution challenging the validity of the said Act and praying for the issue of a writ of mandamus directing the respondents to forbear from giving effect to the provisions of the Act and the notification issued under the Act and/or a writ of prohibition or any other appropriate writ restraining them from taking steps under the provisions of the Act. The appellants challenged the validity of the Act mainly on the grounds that (1) the Act	 rules and the notifications under the Act were ultra vires the Constitution	 because the Act was repugnant to the provisions of article 301 of the Constitution as the tax on carriage of tea through the State of Assam had the effect of interfering with the freedom of trade	 commerce and intercourse; (2) that tea being a controlled industry under the provisions of the Tea Act XXIX of 1953	 the Union Government alone had the power to regulate the manufacture	 production	 distribution or transport of tea and the jurisdiction of the Assam Legislature was thus completely ousted; (3) that the tax under the Act was nothing but a duty of excise	 in substance	 though not in form	 and was thus an encroachment on the Central legislative field within the meaning of entry 84 of the Union List. The impugned Act was also challenged on the ground that it was discriminatory and thus void under article 14 of 817 the Constitution. The competence of the Assam Legislature to legislate on the subject was also questioned. The respondents opposed those petitions under article 226 of the Constitution in the High Court. It was denied by the State that the Act or the rules made thereunder or the notifications issued thereunder were ultra vires the Constitution or that the Act contravened the provisions of article 301 of the Constitution or that it was an encroachment on the sphere of the Union Legislature or was in any way in conflict with the provisions of the Tea Act XXIX of 1953. The case of the respondents was that the Act was in pith and substance	 a legislation to levy tax on certain classes and types of goods carried by road or inland waterways	 strictly within entry No. 56 of the State List. It was also asserted that the Act was within the legislative competence of the Assam Legislature and was not within the terms of the prohibition contained in article 301 of the Constitution. These petitions were heard by a Special Bench of the Assam High Court	 which	 by its judgment and order dated June 6	 1955	 dismissed them holding that the Act was not unconstitutional. Two separate	 but concurring judgments	 were delivered by Sarjoo Prasad	 C. J. and Ram Labbaya	 J. The learned Chief Justice	 in the course of his judgment	 held that the Act contemplated imposition of a tax on transport or carriage of goods within the Meaning of entry 56 of List II and did not amount to interference with the freedom of trade and commerce within the meaning of article 301 of the Constitution ; that the pith and substance of the impugned Act was that it was a taxing legislation which was not directly concerned with trade and commerce	 though it might indirectly entrench on the field of trade and commerce and that article 301 was not directly concerned with taxing laws. He also held that the impost levied by the Act was not in the nature of an excise duty and that there was no substance in the contention that it encroached upon entry 84 of the Union List 1. It was also held that the impugned Act did not	 in any way	 come in conflict with the control of the tea industry 818 introduced by the Central Legislation	 namely	 the Tea Act XXIX of 1953. Ram Labhaya	 J.	 examined the provisions of the impugned Act in great detail and came to the conclusion that the element of carriage was expressly made a condition of liability to tax under the impugned Act and it was	 therefore	 distinguishable from a duty of excise and came directly under entry 56 of List 11. On the crucial question arising in this case	 his conclusion was that taxation per se has not the effect of abridging or curtailing the freedom contemplated by article 301 ; that articles 302 and 304 restrict the powers of Parliament and the State Legislatures in the matter of legislation under entries 42 of List 1	 26 of List 11 and 33 of List III and that restrictions properly so called on the movement of goods and traffic must find their justification from the provisions of Part XIII of the Constitution ; that the impugned Act made provision for taxation which did not directly impinge upon the freedom of trade	 commerce and intercourse within the meaning of article 301. His view also was that in some cases taxation may have the effect of placing restrictions on movement of goods and traffic	 and if it has that effect	 it comes within the mischief of article 301. In the result	 his conclusion was that the impugned Act in its pith and substance fell within the ambit of entry 56 of List 11. He also examined the terms of the Union legislation	 Tea Act No. XXIX of 1953	 and came to the conclusion that the impugned Act did not trespass upon the field of the controlled industry of tea. His conclusion with reference to the argument of discrimination based on article 14 was that there was no proof forthcoming of any real discrimination between persons and things. With these conclusions Deka	 J.	 the third Judge	 entirely agreed. From the judgment of the High Court the appellants have come up in appeal on certificates granted by the High Court. The two petitions under article 32 of the Constitution were filed on behalf of two other producers of tea. They raise the same questions as arise for determination in the three appeals from the decision of the Assam High Court. They have all been 819 heard together And will be dealt with by a common judgment. Mr. Chatterjee	 on behalf of the appellants	 contended that the impugned Act imposed fetters on the free flow of trade and commerce in respect of tea and jute	 the two commodities dealt with by the Act and	 A therefore		 contravened the provisions of article 301 of the Constitution; that the legislation was beyond the legislative competence of the Assam Legislature and was not authorised by entry 56 in List II ; that the tea industry was a controlled industry as declared by Parliament and directly came under entry 52 of List 1 ; that it was a colourable piece of legislation which	 in its true effect	 was a levy of a duty of excise which could only be done by the Union Legislature	 and finally	 that it contravened article 14 of the Constitution. The learned Attorney General on behalf of the State of Assam as also of the Union contended	 on the other hand	 that taxation simpliciter was not within the terms of article 301. Taxation as such is not a restriction within the meaning of Part XIII. It is an attribute of sovereignty	 which is not justiciable. The power to tax is a peculiar legislative function with which the courts are not directly concerned and that	 therefore	 the freedom contemplated by article 301 does not mean freedom from taxation and that taxation is not included within the connotation of the term. " Restriction " in the context of Part XIII meant legislation which had the effect of impeding the free flow of goods and traffic by erection of tariff walls	 for example	 a tariff wall	 if erected by a Legislature	 may be justiciable	 but not legislation simply imposing a tax for purposes of revenue. He further contended that Part XII of the Constitution is a self contained part dealing with finance etc.	 even as Part XIII is a selfcontained part dealing with trade	 commerce and intercourse within the territory of India. He emphasis ed that the American and Australian decisions are no guide to the decision of the points in controversy in the present case	 as the framework of their respective constitutions was entirely different from the Indian 820 Constitution. Particularly	 the Australian Constitution did not contain anything corresponding to Parts III and XII of our Constitution. According to his contention " freedom " in Part XIII meant freedom from discriminatory taxation and freedom from trade barriers. The Advocate General of the several States who appeared in this case supported the viewpoint stressed by the learned Attorney General. The most important question that falls to be determined in this batch of cases is whether the impugned Act infringes the provisions of Part XIII of the Constitution	 with particular reference 'to article 301. Part XIII is headed "Trade Commerce and Intercourse within the Territory of India". Article 301	 which is the opening Article in this Part is in very general terms	 which are as under: " Subject to the other provisions of this part	 trade	 commerce and intercourse throughout the territory of India shall be free ". It is clear that this Part is not subject to the other provisions of the Constitution and the generality of the words used in article 301 is cut down only by the provisions of the other Articles of this Part ending with article 307. It has not been and it could not be contended that the generality of the expressions used in article 301 admit of any Exceptions or explanations not occurring in this Part itself	 nor has it been contended that trade	 commerce and intercourse are subject to any other fetters. All parties are agreed that trade	 commerce and intercourse throughout the territory of India have been emphatically declared by the Constitution to be free	 but there is a wide divergence of views on the answer to the question " free from what ?" It has been contended on behalf of the appellants that the answer to this question must be that trade	 commerce and intercourse throughout India	 shall be free from everything including taxation. On the other hand	 the contention on behalf of the Union Government and the State Government is that the freedom envisaged by article 301 does not include immunity from taxation and that freedom means that there shall be no trade barriers or tariff 821 walls shutting out commodities	 traffic and intercourse between individuals	 and no shutting in. In order fully to appreciate the implications of the provisions of Part XIII of the Constitution	 it is necessary to bear in mind the history and background of those provisions. The Constitution Act of 1935 (Government of India Act	 26 ( 'Teo. 5	 Ch. 2) which envisaged a federal constitution for the whole of India	 including what was then Indian India in contradistinction to British India	 which could not be fully implemented and which also introduced full provincial autonomy enacted section 297 prohibiting certain restrictions on internal trade in these terms: " 297. (1) No Provincial Legislature or Government shall (a) by virtue of the entry in the Provincial Legislative List relating to trade and commerce within the Province	 or the entry in that list relating to the production	 supply	 and distribution of commodities	 have power to pass any law or take any executive action prohibiting or restricting the entry into	 or export from the Province of goods of any class or description ; or (b) by virtue of anything in this Act have power to impose any tax	 cess	 toll or due which	 as between goods manufactured or produced in the Province and similar goods not so 'manufactured or produced	 discriminates in favour of the former	 or which	 in the case of goods manufactured or produced outside the Province	 discriminates between goods manufactured or produced in one locality and similar goods manufactured or produced in another locality. (2) Any law passed in contravention of this section shall	 to the extent of the contravention	 be invalid. " It will be noticed that the prohibition contained in the section quoted above applied only to Provincial Governments and Provincial Legislatures with reference to entries in the Provincial Legislative List relating to trade and commerce within the Province and to production	 supply and distribution of commodities. That section dealt with prohibitions or 105 822 restrictions in respect of import into or export from a Province	 of goods generally. It also dealt with the power to impose taxes etc. and prohibited discrimination against goods manufactured or produced outside a Province or goods produced in different localities. Part XIII of the Constitution has introduced all those prohibitions	 not only in respect of State Legislatures	 but of Parliament also. In other words	 Part XIII enlarges the scope of the inhibitions and lays down the limits within which the Union Parliament or a State Legislature may legislate with reference to trade	 commerce and intercourse inter State	 intrastate and throughout the territory of India. In this connection it has got to be remembered that before the commencement of the Constitution about two thirds of India was directly under British rule and was called ' British India ' and the remaining about one third was being directly ruled by the Princes and was known as Native States. There were a large number of them with varying degrees of sovereignty vested in them. Those rulers had	 broadly speaking	 the trappings of a Sovereign State with power to impose taxes and to regulate the flow of trade	 commerce and intercourse. It is a notorious fact that many of them had erected trade barriers seriously impeding the free flow of trade	 commerce and intercourse	 not only shutting out but also shutting in commodities meant for mass consumption. Between the years 1947 and 1950 almost all the Indian States entered into engagements with the Government of India and ultimately merged their individualities into India as one political unit	 with the result that what was called British India	 broadly speaking	 became	 under the Constitution	 Part A States	 and subject to certain exceptions not relevant to our purpose	 the Native States became Part B States. We also know that before the Consti tution introduced the categories of Part A States	 Part B States and Part C States (excluding Part D relating to other territories)	 Part B States themselves	 before their being constituted into so many units	 contained many small States	 which formed themselves into 823 Unions of a number of States	 and had such trade barriers and custom posts	 even inter se. But even after the merger	 the Constitution had to take notice of the existence of trade barriers and therefore had to make transitional provisions with the ultimate objective of abolishing them all. Most of those Native States	 big or small	 had their own taxes	 cesses	 tolls and other imposts and duties meant not only for raising revenue	 but also as trade barriers and tariff walls. It was in the background of these facts and circumstances that the Constitution by article 301 provided for the abolition of all those trade barriers and tariff walls. When for the first time in the history of India the entire territory within the geographical boundaries of India	 minus what became Pakistan	 was knit into one political unit	 it was necessary to abolish all those trade barriers and custom posts in the interest of national solidarity	 economic and cultural unity as also of freedom of trade	 commerce and intercourse. It is in the background of these facts and circumstances that we have to determine the ambit of the freedom contemplated by article 301. That Article envisages freedom of trade and commerce with reference to different parts of India as also freedom of movement of individuals in relation to their trade and other activities. Hence	 article 301 has reference not only to trade and commerce	 as ordinarily understood in common parlance	 but also in relation to individuals who have to move with their goods and commodities throughout the length and breadth of the country. Movement of traffic in goods and commodities as also of persons can be by railway or airways	 by road or by inland waterways etc.	 etc. Carriage of goods and passengers by railway	 by sea or by air or by national waterways is covered by entry 30 of List 1 and taxes on railway fares and freights and terminal taxes on goods or passengers carried by railway	 sea or air come under the purview of entry 89 in the same List. On the other hand	 taxes on goods and passengers carried by road or inland waterways come under entry 56 of List II (State List). It will thus be seen that the Constitution makers contemplated taxes 824 on goods and passengers to be imposed by the Parliament on journeys covered by railway or by sea or by air; and by State Legislatures on journeys by road or inland waterways. The power to tax is inherent in sovereignty. The sovereign State	 in some cases the Union	 in other cases the State	 has the inherent power to impose taxes in order to raise revenue for purposes of State. Such a sovereign power ordinarily is not justiciable	 simply because the State in its legislative department has to determine the policy and incidence of taxation. It is the St ate which determines	 through the Legislature	 what taxes to impose	 on whom and to what extent. The judicial department of the State is not expected to deal with such matters	 because it is not for the courts to determine the policy and incidence of taxation. This power of the State to raise finances for Government purposes has been dealt with by Part XII of the Constitution	 which contains the total prohibition of levy or collection of tax	 except by authority of law (article 265). This Part also deals with the distribution of revenue between the Union and the States. It does not clearly demarcate the taxing authority as between the Union and the States and therefore had to indicate in great detail what taxes shall be levied for the benefit of the Union or for the benefit of the States and what taxes may be levied and collected by the Union for the benefit of the States and the principle according to which those revenues have to be distributed amongst the constituent States of the Union. In short	 Part XII is a self contained series of provisions relating to the finances of the Union and of the States and their interrelation and adjustments (ignoring the provisions in Chapter 2 of that Part relating to borrowing and Chapter 3 relating to property contracts etc.). Like Part XIII	 Part XII also is not expressed to be subject to the other provisions of the Constitution. Hence	 both Parts XII and XIII are meant to be self contained in their respective fields. It cannot	 therefore	 be said that the one is subject. to the other. But it has been argued on behalf of the appellants that the pro. visions of article 304 indicate that taxation is within 825 the purview of the overriding provisions	 as they have been characterised	 of article 301. But a close examination of the provisions of article 304 would show that it is divided into two parts	 viz.	 (1) dealing with imposition of discriminatory taxes by a State Legislature; and (2) relating to imposition of reasonable restrictions	 thus showing that imposition of taxes	 discriminatory or otherwise	 is a class apart from imposition of reasonable restrictions on freedom of trade	 commerce and intercourse. The second part of article 304 dealing with imposition of reasonable restrictions on freedom of trade	 commerce and intercourse by a State Legislature is on a line with the imposition by Parliament of such restrictions between one State and another or within any part of the territory of India in public interest	 contained in article 302. The provisions of article 303 further make it clear that the giving Of preference to one State over another or discrimination between one State and another are clearly within the purview of Part XIII	 that is to say	 they are calculated to impede the freedom of trade	 commerce and intercourse. There is a prohibition against Parliament as also against the Legislature of a State making any law giving preference to one State over another or making or authorising the making of any discrimination between one State and another. But the most significant words in connection with giving preference or making discrimination as envisaged in article 303 are with reference to " any entry relating to trade and commerce in any of the Lists in the Seventh Schedule"	 that is to say	 entry 42 in List 1	 entry 26 in List II and entry 33 in List III of the Seventh Schedule. Hence	 any legislation under those entries which has the effect of directly interfering with trade	 commerce and intercourse being free throughout the territory of India has to be struck down as infringing the provisions of article 301. But in this matter also the Constitution makers had before them situations of emergency	 say for example	 created by drought or overflooding resulting in scarcity of commodities like foodgrains etc. In such a situation	 Parliament has been armed with the power to grant preference to one State over 826 another or to make a discrimination as between two and more States if the Law dealing with such a situation declares that it is necessary to do so in order to deal with an emergency like the one referred to above. In this connection it may not be emphasised that article 303 has not been very accurately worded inasmuch as the non obstante clause	 with which the Article opens	 has reference only to article 302	 which empowers Parliament to impose by law restrictions on the freedom of trade	 commerce or intercourse	 inter State or intraState	 in public interest. But the non obstante clause is immediately followed by reference not only to Parliament but also to the Legislature of a State which are armed with the power of giving preference or making discrimination as aforesaid in respect of the entries relating to trade and commerce in any of the lists in the Seventh Schedule. Here	 no reference is made to intercourse. But as the present controversy is not concerned with the freedom of intercourse	 as distinguished from the freedom of trade and commerce	 no more need be said about that omission. Learned counsel for the appellants vehemently argued that the freedom contemplated by article 301 Must be construed in its most comprehensive sense of freedom from all kinds of impediments	 restraints and trade barriers	 including freedom from all taxation. In my opinion	 there is no warrant for such an extreme position. It has to be remembered that trade	 commerce and intercourse include individual freedom of movement of every citizen of India from State to State	 which is also guaranteed by article 19(1)(d) of the Constitution. The three terms used in article 301 include not only free buying and selling	 but also the freedom of bargain and contract and transmission of informa tion relating to such bargains and contracts as also transport of goods and commodities for the purposes of production	 distribution and consumption in all their aspects	 that is to say	 transportation by land	 air or water. They must also include commerce not only in goods and commodities	 but also transportation of men and animals by all means of transportation. Commerce would thus include dealings over the telegraph	 827 telephone or wireless and every kind of contract relating to sale	 purchase	 exchange etc. of goods and commodities. Viewed in this all comprehensive sense taxation on trade	 commerce and intercourse would have many ramifications and would cover almost the entire field of public taxation	 both in the Union and in the State Lists. It is almost impossible to think that the makers of the Constitution intended to make trade	 commerce and intercourse free from taxation in that comprehensive sense. If that were so	 all laws of taxation relating to sale and purchase of goods on carriage of goods and commodities	 men and animals	 from one place to another	 both inter State and intraState	 would come within the purview of article 301 and the proviso to article 304 (b) would make it necessary that all Bills or Amendments of pre existing laws shall have to go through the gamut prescribed by that proviso. That will be putting too great an impedi ment to the power of taxation vested in the States and reduce the States ' limited sovereignty under the Constitution to a mere fiction. That extreme position has	 therefore	 to be rejected as unsound. In this connection	 it is also pertinent to bear in mind that all taxation is not necessarily an impediment or a restraint in the matter of trade	 commerce and intercourse. Instead of being such impediments or restraints	 they may	 on the other hand	 provide the wherewithal; to improve different kinds of means of transport	 for example	 in cane growing areas	 unless there are good roads	 facility for transport of sugarcane from sugarcane fields to sugar mills may be wholly lacking or insufficient. In order to make new roads as also to improve old ones	 cess on the grower of cane or others interested in the transport of this commodity has to be imposed	 and has been known in some parts of India to have been imposed at a certain rate per maund or ton of sugarcane transported to sugar factories. Such an imposition is a tax on transport of sugarcane from one place to another	 either intrastate or inter State. It is the tax thus realised that makes it feasible for opening new means of 828 communication or for improving old ones. It cannot	 therefore	 be said that taxation in every case must mean an impediment or restraint against free flow of trade and commerce. Similarly	 for the facility of passengers and goods by motor transport or by railway	 a surcharge on usual fares or freights is levied	 or may be levied in future. But for such a surcharge	 improvement in the means of communication may not be available at all. Hence	 in my opinion	 it is not correct to characterise a tax on movement of goods or passengers as necessarily connoting an impediment	 or a restraint	 in the matter of trade and commerce. That is another good reason in support of the conclusion that taxation is not ordinarily included within the terms of article 301 of the Constitution. In my opinion	 another very cogent reason for holding that taxation simpliciter is not within the terms of article 301 of the Constitution is that the very connotation of taxation is the power of the State to raise money for public purposes by compelling the payment by persons	 both natural and juristic	 of monies earned or possessed by them	 by virtue of the facilities and protection afforded by the State. Stich burdens or imposts	 either direct or indirect	 are in the ultimate analysis meant as a contribution by the citizens or persons residing in the State or dealing with the citizens of the State	 for the support of the Govern ment	 with particular reference to their respective abilities to make such contributions. Thus public purpose is implicit in every taxation	 as such. There. fore	 when Part XIII of the Constitution speaks of imposition of reasonable restrictions in public interest	 it could not have intended to include taxation within the generic term " reasonable restrictions ". This Court has laid it down in the case of Ramjilal vs Income Tax Officer	 Mohindargarh (1) that imposition and collection of taxes by authority of law envisaged by article 265 is outside the scope of the expression " deprivation of property " in article 31(1) of the Constitution. Reasonable restrictions as used in Part III or Part XIII of the Constitution would in most cases be less (1) ; 	136. 829 than total deprivation of property rights. Hence	 Part XII dealing with finance etc. as already indicated	 has been treated as a Part dealing with the sovereign power of the State to impose taxes	 which must always mean imposing burdens on citizens and others	 in public interest. If a law is passed by	 the Legislature imposing a tax which in its true nature and effect is meant to impose an impediment to the free flow of trade	 commerce and intercourse	 for example	 by imposing a high tariff wall	 or by preventing imports into or exports out of a State	 such a law is outside the significance of taxation	 as such	 but assumes the character of a trade barrier which it was the intention of the Constitution makers to abolish by Part XIII. The objections against the contention that taxation was included within the prohibition contained in Part XIII may thus be summarised: (1) Taxation	 as such	 always implies that it is in public interest. Hence	 it would be outside particular restrictions	 which may be characterised by the courts as reasonable and in public interest. (2) The power is vested in a sovereign State to carry on Government. Our Constitution has laid the foundations of a welfare State	 which means very much expanding the scope of the activities of Government and administration	 thus making it necessary for the State to impose taxes on a much larger scale and in much wider fields. The legislative entries in the three Lists referred to above empowering the Union Government and the State Governments to impose certain taxations with refe rence to movement of goods and passengers would be rendered ineffective	 if not otiose	 if it were held that taxation simpliciter is within the terms of article 301. (3) If the argument on behalf of the appellants were accepted	 many taxes	 for example	 sales tax by the Union and by the States	 would have to go through the gamut prescribed in articles 303 and 304	 thus very much detracting from the limited sovereignty of the States	 as envisaged by the Constitution. (4) Laws relating to taxation	 which is essentially a legislative function of the State	 will become justiciable and every 106 830 time a taxation law is challenged as unconstitutional	 the State will have to satisfy the courts a course which will seriously affect the division of powers on which modern constitutions	 including ours	 are based. (5) Taxation on movement of goods and passengers is not necessarily an impediment. That conclusion leads to a discussion of the other extreme position that taxation is wholly out of the purview of article 301. That extreme position is equally untenable in view of the fact that article 304 contains	 and article 306	 before it was repealed in 1956	 contained	 reference to taxation for certain purposes mentioned in those Articles. But article 306	 which now stands repealed	 contained references to tax or duty on the import of goods into one State from another or on the exports of goods from one State to another. Such imposts were really in the nature of impediments to the free flow of goods and commodities on account of customs barriers	 which it was the intention of article 301 to abolish. Similarly	 article 304 while recognising the power of a State Legislature to tax goods imported inter State	 insists that a similar tax is imposed on goods manufactured or produced within the State. The Article thus brings out the clear distinction between taxation as such for the purpose of revenue and taxation for purposes of making discrimination or giving preference	 both of which are treated by the Constitution as impediments to free trade and commerce. In other words	 so long as the impost was not in the nature of an impediment to the free flow of goods and commodities between one State and another	 including in this expression Union territories also	 its legality was not subject to an attack based on the provisions of Part XIII. But that does not mean that State Legislatures derive their power of taxation by virtue of what is contained in article 304. Article 304 only left intact such power of taxation	 but contained the inhibition that such taxes shall not be permitted to have the effect of impeding the free flow of goods and commodities. Article 301	 with which Part XIII commences	 contains the crucial words " shall be free " and provides 831 the key to the solution of the problems posed by the whole Part. The freedom declared by this Article is not an absolute freedom from all legislation. As already indicated	 the several entries in the three Lists would suggest that both Parliament and State Legislatures have been given the power to legislate in respect of trade	 commerce and intercourse	 but it is equally clear that legislation should not have the effect of putting impediments in the way of free flow of trade and commerce. In my opinion	 it is equally clear that the freedom envisaged by the Article is not an absolute freedom from the incidence of taxation in respect of trade	 commerce and intercourse	 as shown by entries 89 and 92 A in List 1	 entries 52	 54 and 56 to 60 in List II and entry 35 in List 111. All these entries in terms speak of taxation in relation to different aspects of trade	 commerce and intercourse. The Union and State Legislature	 therefore	 have the power to legislate by way of taxation in respect of trade	 commerce and intercourse	 so as not to erect trade barriers	 tariff walls or imposts	 which have a deleterious effect on the free flow of trade	 commerce and intercourse. That freedom has further been circumscribed by the power vested in Parliament or in the Legislature of a State to impose restrictions in the public interest. Parliament has further been authorised to legislate in the way of giving preference or making discrimination in certain strictly limited circumstances indicated in el. (2) of article 303. Thus	 on a fair construction of the provisions of Part XIII	 the following propositions emerge: (1) trade	 commerce	 and intercourse throughout the territory of India are not absolutely free	 but are subject to certain powers of legislation by Parliament or the Legislature of a State; (2) the freedom declared by article 301 does not mean freedom from taxation simpliciter	 but does mean freedom from taxation which has the effect of directly impeding the free flow of trade	 commerce and intercourse; (3) the freedom envisaged in article 301 is subject to non discriminatory restrictions imposed by Parliament in public interest (article 302); (4) even discriminatory or preferential legisla 832 tion may be made by Parliament for the purpose of dealing with an emergency like a scarcity of goods in any part of India (article 303(2)); (5) reasonable restrictions may be imposed by the Legislature of a State in the public interest (article 304(b)); (6) non discriminatory taxes may be imposed by the Legislature of a State on goods imported from another State or other States	 if similar taxes are imposed on goods produced or manufactured in that State (article 304(a)); and lastly (7) restrictions imposed by existing laws have been continued	 except in so far as the President may by order otherwise direct (article 305). After having discussed the arguments for and against the proposition that article 301 includes within its large sweep taxation simpliciter	 I now proceed to discuss the terms of the impugned Act in order to find out whether in the light of the discussion above	 any of its provisions are liable to be struck down as unconstitutional	 because they infringe article 301	 as contended on behalf of the appellants. The Act	 as the preamble shows	 is intended to " impose a tax on certain goods carried by road or inland waterways Dealer " has been defined in section 2(4) as under: "Dealer ' means a person who owns jute in bales before it is carried by motor vehicle	 cart	 trolley	 boat	 animal and human agency or any other means except railways or airways and includes his agent. " Producer has been defined by cl. '(12) of section 2 as follows: " 'Producer ' means a producer of tea and includes the person in charge of the garden where tea is produced ". Section 3	 which is the charging section	 provides that manufactured tea in chests carried by motor vehicle	 etc.	 except railways and airways	 shall be liable to a tax at a certain rate per pound of such tea and that this tax shall be realised from the producer. It also provides that jute carried in bales by motor vehicle	 etc.	 except railways and airways	 shall be liable to a tax at a certain rate per maund on such jute	 which shall be realised from the dealer. It is not necessary 833 to set out the rate of taxes aforesaid	 because 'no argument was advanced to the effect that they were oppressive or excessive. The tax on manufactured tea in chests is to be paid by the producer	 which term includes the person in charge of the garden where tea is produced. This provision has occasioned the argument that it is an excise duty in the garb of a tax and will be dealt with later in the course of this judgment. The tax on jute carried in bales is made realisable from the dealer which means a person who owns the jute in bales. Section 6 lays down the taxing authorities. Section 7 requires every producer and dealer to furnish returns of such tea or such jute as have been made liable to tax under section 3	 as aforesaid. Section 8 makes provision for licensing of balers	 which means persons who own or possess a pressing machine for the compression of jute into bales. Section 9 lays down the procedure of assessment and section 10 the procedure for cancellation of assessment in certain cir cumstances. Section 11 lays down the procedure for assessment in such cases as have escaped assessment or there has been an evasion of the tax. It is not necessary to refer to the other provisions of the Act	 because they are not relevant to the arguments advanced at the Bar. It will be seen from the bare summary of the relevant provisions of the statute that it is a taxing statute simpliciter without the least suggestion even of any attempt at discrimination against dealers and producers outside the State of Assam or of preference in favour of those inside the State. On the face of it	 therefore	 the Act does not suffer from any of the vices against which Part XIII of the Constitution was intended. It has not been suggested that the Act imposes a heavy burden on the dealer or the producer as the case may be. On the terms of the Statute	 it cannot be said that it is intended to put obstacles or impediments in the way of free flow of traffic in respect of jute and tea. On the face of it	 it would not be in the interest of the State of Assam to put any such impediments	 because Assam is a large producer of those commodities and the market for those commodities is mainly in Calcutta. 834 In those I circumstances	 it is difficult	 if not impossible	 to come to the conclusion that the Act comes within the purview of article 301 of the Constitution. If that is so	 no further consideration arising out of the other provisions of Part XIII of the Constitution calls for any decision. Having thus disposed of the main ground of attack against the constitutionality of the Act based on article 301 of the Constitution	 it is necessary to advert to the other contentions raised on behalf of the appellants. It has been contended that the Act is beyond the legislative competence of the Assam Legislature. We have	 therefore	 to address ourselves to the question whether or not it is covered by any of the entries in List 11 of the Seventh Schedule. Entry 56	 in its very terms	 " Taxes on goods and passengers carried by rail or in inland waterways "	 completely covers the impugned Act. There is no occasion in this case to take recourse to the doctrine of pith and substance	 inasmuch as the Act is a simple piece of taxing statute meant to tax transport of goods	 in this case jute and tea	 by road or on inland waterways. In my opinion	 it is a very simple case of taxation completely covered by entry 56	 but the argument against the competence of the Assam Legislature has been sought to be supported by the subsidiary contention that though in form it is a tax on the transport of goods within the terms of entry 56	 in substance it is an imposition of excise duty within the meaning of entry 84 in List 1 of the Seventh Schedule	 but	 in my opinion	 there is no substance in this contention for the simple reason that so long as jute or tea is not sought to be transported from one place to another	 within the State or outside the State	 no tax is sought to be levied by the Act. It is only when those goods are put on a motor truck or a boat or a steamer or other modes of transport contemplated by the Act	 that the occa sion for the payment of tax arises. A similar argument was advanced in the case of The Tata Iron & Steel Co. Ltd. vs The State of Bihar (2)	 and Das	 C. J.	 delivering the majority judgment of the Court	 disposed of the argument that the tax in that case was not (2) ; 835 on sale of goods	 but was	 in substance	 a duty of excise	 in these terms: " This argument	 however	 overlooks the fact that under el. (ii) the producer or manufacturer became liable to pay the tax not because he produced or manufactured the goods	 but because he sold the goods. In other words the tax was laid on the producer or manufacturer only qua seller and not qua manufacturer or producer as pointed out in Boddu Paidanna 's case In the words of their Lordships of the Judicial Committee in Governor General vs Province of Madras	 72 I.A. 91 at p. 103	 ' a duty of excise is primarily a duty levied on a manufacturer or producer in respect of the commodity manufactured or produced. It is a tax on goods not on sales or the proceeds of sale of goods '. If the goods produced or manufactured in Bihar were destroyed by fire before sale the manufacturer or producer would not have been liable to pay any tax under section 4(1) read with section 2(g)	 second proviso. As Gwyer	 C. J.	 said in Boddu Paidanna 's case	 supra	 at p. 102	 the manufacturer or producer would be liable	 if at all	 to a sales tax because he sells and not because he manufactures or produces; and he would be free from liability if he chose to give away everything which came from his factory '. " (See p. 1369 of the Report). The observations quoted above completely cover the present controversy. The Legislature has chosen the dealer or the producer as the convenient agency for collection of the tax imposed by section 3	 but the occasion for the imposition of the tax is not the production or the dealing	 but the transport of those goods. It must	 therefore	 be held that the Act does what it sets out to do	 namely to impose a tax on goods carried by road or on inland waterways. Another line of argument directed to the same end	 namely	 of attacking the competence of the Assam Legislature was that it impinged on the provisions of the Tea Act	 XXIX of 1953. It was argued that the tea industry was a controlled one within the competence the Union Legislature. The Tea Act declared that it was expedient in the public interest that the 836 Union should take the tea industry under its control. With a view to controlling the industry in public interest the Act established the Tea Board (section 4) whose function it was	 inter alia	 to regulate the production and extent of cultivation of tea	 of improving the quality of tea	 of promoting co operative effort among growers and manufacturers of tea	 etc.	 etc. (section 10). With the objectives aforesaid	 Chapter III lays down provisions for the control over the extension of tea cultivation and Chapter IV deals with provisions for control over the export of tea and tea seed. Chapter V lays down provisions for the imposition of duty of customs on export of tea outside India and the proceeds of the cess thus levied have to be credited to the Consolidated Fund of India. Out of that Fund	 called the Tea Fund	 the expenses of the establishment created by the Tea Act have to be met. The rest of the provisions of the Act are meant to implement the main provisions of the Act. There are no provisions of the Tea Act which can be said to come into conflict with the provisions of the impugned Act. In our opinion	 therefore	 this ground of attack also fails. A third line of argument against the constitutionality of the Act was that it is extra territorial in its operation in so far as it purports to tax producers and dealers who may not be residents of the State of Assam. This argument has been advanced in the interest of the appellants and petitioners from West Bengal	 who have to carry their goods by road or on waterways passing through the territory of Assam	 from one part of West Bengal to another. So far as this group of cases is concerned	 the main grievance of the appellants is that no doubt their goods have to pass through a portion of the territory of Assam	 but the goods have been produced	 packed and transported as merchandise from one part of West Bengal to another part of the same State. It is not denied that there is some real and substantial nexus to support the taxing statute	 but it is contended that relatively to the whole journey to be covered by the merchandise	 the portion of the territory of Assam covered in 837 that journey is very small. But in judging the validity of a legislation with reference to the contention based on extra territoriality it is not relevant to consider the question of the proportion between the extent of territorial nexus to the whole length of the journey. If goods belonging to or carried by the appellants traverse any of the territory of Assam the taxation cannot be successfully assailed on this ground	 once it is held that it was within the legislative competence of the Legislature imposing the tax in question. See in this connection the observations of this Court in The Tata Iron and Steel Co. Ltd. vs The State of Bihar (1) at pp. 1369 to 1371	 where Das	 C. J.	 speaking for the majority of the Court	 has examined the theory of nexus with reference to a large body of case law bearing on the question. I respectfully adopt that line of reasoning and hold that the Act does not suffer from the vice of extra territoriality. It is true that the incidence of the taxation may fall upon per.sons not ordinarily residing in the State of Assam or upon goods not produced in Assam	 but	 in this connection	 it is enough to point out that what has been said above in respect of the tax being in the nature of a duty of excise applies which equal force to this part of the argument also. The tax is leviable from such goods as traverse in their journey any part of the territory of Assam	 not because the owners or the producers are residents of Assam	 but because the waterway or the roadway situate in the territory of Assam has been utilised for a portion of the journey. It is clear	 therefore	 that there is no infirmity attaching to the Act on the ground that it is extra territorial in its operation. It only remains to consider the last ground of attack	 namely	 that the Act is discriminatory in character and thus infringes article 14 of the Constitution. In this connection	 it has been argued that only tea in chests and jute in bales have been selected for taxation	 leaving the same commodities in other hands or in other forms	 or in other receptacles (1) 107 838 free from the incidence of the taxation in question. The Legislature has chosen to tax the transport over land or over waterways of those commodities	 in chests or in bales	 apparently because those are the most convenient and usually employed methods of packing for carriage of those goods to long distances. Hence	 it is not a case of choosing for the purposes of taxation one class of goods in preference to another class of the same variety. The Legislature was out to tax the transport of those commodities and must be presumed to have selected the most convenient way of doing it. It has not been suggested that any large amount of such commodities is transported over long distances	 otherwise than in chests or bales. Furthermore	 if the Legislature has to tax something	 it is not bound to tax that thing in all its forms and varieties. It may pick and choose with a view to raising such amount of revenue as it sets out to do. It is not for the courts to say that there were other ways of doing the thing or that all forms and varities should have been brought under the scope of the taxation. It is open to the Legislature to impose a tax in a form and in a way which it deems most convenient for the purposes of collection and calculation of the tax. As all the grounds of attack raised against the con stitutionality of the Act fail	 the appeals and the petitions	 in my opinion	 should be dismissed with costs. I have deliberately refrained from making references to or relying upon decisions from other countries like the U. section A. or Australia	 because the cases decided in those countries cannot be any guide for the solution of the problems raised in this case inasmuch as the framework of the Constitution in those countries is not in pari materia with ours. Any precedents deciding cases on the construction of statutes	 which are worded differently from ours	 cannot	 in my opinion	 be a safe guide for the decision of controversies raised in terms of our Constitution. I regret to have to differ from the majority of the Court	 but my only justification for taking a different view is that my reading of Part XIII of the 839 Constitution does not justify the inference that taxation simpliciter is within the terms of article 301 of the Con stitution. GAJENDRAGADKAR J. The vexed question posed by the construction of the provisions of Part XIII Of A the Constitution which has been incidentally discussed in some reported decisions of this Court falls to be Ga considered in the present group of cases. This group consists of three appeals brought to this Court with a certificate issued by the Assam High Court under article 132 and two petitions filed under article 32. The three appellants are tea companies	 two of which (Civil Appeal No. 126 of 1958 and Civil Appeal No. 128 of 1958) carry on their trade of growing tea in the District of Sibsagar in Assam while the third (Civil Appeal No. 127 of 1958) carries on its trade in Jalpaiguri in West Bengal. All the three companies which would be described hereafter as the appellants carry their tea to Calcutta in order that it may be sold in the Calcutta market for home consumption or export outside India. Tea produced in Jalpaiguri has also to pass through a few miles of territory in the State of Assam	 while the tea produced in Assam has to go all the way through Assam to reach Calcutta. It appears that a very small pro portion of tea produced and manufactured in Assam finds a market in Assam itself; bulk of it finds its custom in the market at Calcutta. Besides the tea which is carried by rail a substantial quantity has to go by road or by inland waterways and as such it becomes liable to pay the tax leviable under the Assam Taxation (on goods carried by Roads or Inland Waterways) Act	 1954 (Act XIII of 1954) (hereafter called the Act). The Act has been passed by the Assam Legislature in order to provide for the levy of a tax on certain goods carried by road or inland waterways in the State of Assam and it has received the assent of the Governor on April 9	1954. On behalf of the State of Assam	 which will be described hereafter as respondent	 its officers required the appellants to comply with the several requirements imposed by the Act	 and made tax 840 demands on them in respect of the tea carried by them. The tax thus demanded was paid by the appellants under protest	 and soon thereafter petitions were filed in the Assam High Court under article 226 challenging the validity of the Act as well as the tax demands made by the officers of the respondent. By J. their respective petitions the appellants prayed that a writ of mandamus should issue directing the respondent and its officers to forbear from giving effect to the provisions of the Act and from otherwise enforcing it against the appellants. The petitioners also claimed alternatively a writ of prohibition or any other appropriate writ restraining the respondent and its officers from enforcing the Act against the appellants. That is how the validity of the Act came before the Assam High Court for judicial scrutiny. The appellants challenged the vires of the Act on several grounds. The principal ground	 however	 was that the Act had violated the provisions of article 301 of the Constitution	 and since it did not comply with the provisions of article 304(b) it was ultra vires. It was also urged that tea was a controlled industry under the provisions of Act 29 of 1953	 and so it was the Union Government alone which was competent to regulate the manufacture	 production	 distribution or transport of the said commodity ; that being so the Assam Legislature was not competent to pass the Act. The validity of the Act was further challenged on the	 ground that	 though the Act purported to have been passed under Entry 56 of List 11	 in substance and in reality it was a duty of excise and as such it could be enacted only under Entry 84 of List 1. According to the appellants the Act also suffered from the vice that it was violative of the fundamental right of equality before the law guaranteed by article 14. The correctness of these contentions was disputed by the respondent. It urged that the Act was perfectly within the competence of the Assam Legislature under Entry 56 of List II and that the provisions of Part XIII were wholly inapplicable to it. The respondent further pleaded that article 14 had not been violated and that there was no substance in the 841 argument that as controlled industry it is only the Union Government which could deal with it or that in reality the Act bad imposed a duty of excise. The petitions filed by the appellants were heard by a Special Bench of the Assam High Court. All the pleas raised by the appellants were rejected by Sarjoo Prasad	 C. J. and Ram Labhaya	 J.	 who delivered		 separate but concurring judgments. The appellants ' then applied for and obtained a certificate from the High Court under article 132 ; that is how the three appeals have come to this Court	 and they raise for our decision all the points which were argued before the High Court. Naturally the principal contention which has been urged before us at length centres round the applicability of Part XIII. The two petitions filed under article 32 raise substantially the same question. The petitioners are tea companies which carry on the trade of growing and manufacturing tea in Jalpaiguri in West Bengal. The respondent has attempted to subject the petitioners to the provisions of the Act	 and the petitioners have challenged the authority of the respondent to levy a tax against them under the Act on the ground that the Act is ultra vires. Since the principal question raised in these appeals appeared to be of considerable importance in which other States may also be interested we directed that notice should be issued to the Attorney General of India and the Advocates General in all the States of India. Accordingly the Attorney. General appeared before us and the States of Bihar	 Madras	 Punjab	 Rajasthan and Uttar Pradesh have also been heard. The challenge to the vires of the Act on the ground that it contravenes article 301 necessarily raises the question about the construction of the relevant provisions in the said Part. article 301 with which Part XIII begins provides that " subject to the other provisions of this Part trade	 commerce and intercourse through. out the territory of India shall be free ". The appellants contend that this provision imposes a limitation on the legislative power of the State Legislatures as well as the Parliament	 and the vires of the Act will 842 have to be judged on that basis. The words used in article 301 are wide and unambiguous and it would be unreasonable to exclude from their ambit a taxing law which restricts trade	 commerce or intercourse either directly or indirectly. On the other band	 the respondent the Attorney General	 and the other States have urged that taxing laws stand by themselves; 'they are governed by the provisions of Part XII and no provision of Part XIII can be extended to them. In the alternative it has been suggested that the provisions of Part XIII should be applied only to such legislative entries in the Seventh Schedule which deal with trade	 commerce and intercourse. This alternative argument would bring within the purview of Part XIII Entry 42 in List I which refers to interState trade and commerce	 Entry 26 in List II which deals with trade and commerce	 within the State subject to the provisions of Entry 33 in List III	 and Entry 33 in List III which deals with trade and commerce as therein specified. The arguments thus presented by both the parties appear prima facie to be logical and can claim the merit of attractive simplicity. The question which we have to decide is which of the contentions correctly represents the true position in law. Does truth lie in one or the other contention raised by the parties	 or does it lie midway between those contentions ? This problem has to be resolved primarily by adopting a fair and reasonable construction of the relevant Articles in Part XIII; but before we attempt that task it would be relevant to deal with some general considerations. Let us first recall the political and constitutional background of Part XIII. It is a matter of common knowledge that	 before the Constitution was adopted	 nearly two thirds of the territory of India was subject to British Rule and was then known as British India	 while the remaining part of the territory of India was governed by Indian Princes and it consisted of several Indian States. A large number of these States claimed sovereign rights within the limitations imposed by the paramount power in that behalf	 and they pur ported to exercise their legislative power of imposing 843 taxes in respect of trade and commerce which inevitably led to the erection of customs barriers between themselves and the rest of India. In the matter of such barriers British India was governed by the provisions of section 297 of the Constitution Act	 1935. To the provisions of this section we will have occasion later to refer during the course of this judgment. Thus	 prior to 1950 the flow of trade and commerce was impeded at several points which constituted the boundaries of Indian States. After India attained political freedom in 1947 and before the Constitution was adopted the historical process of the merger and integration of the several Indian States with the rest of the country was speedily accomplished with the result that when the Constitution was first passed the territories of India consisted of Part A States which broadly stated represented the Provinces in British India	 and Part B States which were made up of Indian States. This merger or integration of Indian States with the Union of India was preceded by the merger and consolidation of some of the States interse between themselves. It is with the knowledge of the trade barriers which had been raised by the Indian States in exercise of their legislative powers that the Constitution makers framed the Articles in Part XIII. The main object of article 301 obviously was to allow the free flow of the stream of trade	 commerce and intercourse throughout the territory of India. In drafting the relevant Articles of Part XIII the makers of the Constitution were fully conscious that economic unity was absolutely essential for the stability and progress of the federal policy which had been adopted by the Constitution for the governance of the country. Political freedom which had been won	 and political unity which had been accomplished by the Constitution	 had to be sustained and strengthened by the bond of economic unity. It was realised that in course of time different political parties believing in different economic theories or ideologies may come in power in the several constituent units of the Union	 and that may conceivably give rise to local and 844 regional pulls and pressures in economic matters. Local or regional fears or apprehensions raised by local or regional problems may persuade the State Legislatures to adopt remedial measures intended solely for the protection of regional interests without due regard to their effect on the economy of the nation as a whole. The object of Part XIII was to avoid such a possibility. Free movement and exchange of goods throughout the territory of India is essential for the economy of the nation and for sustaining and improving living standards of the country. The provision contained in article 301 guaranteeing the freedom of trade	 commerce and intercourse is not a declaration of a mere platitude	 or the expression of a pious hope of a declaratory character; it is not also a mere statement of a directive principle of State policy ; it embodies and enshrines a principle of paramount importance that the economic unity of the country will provide the main sustaining force for the stability and progress of the political and cultural unity of the country. In appreciating the significance of these general consi derations we may profitably refer to the observations made by Cardozo	 J.	 in C.A.F. Seelig	 Inc. vs Charles H. Baldwin(1) while he was dealing with the commerce clause contained in article 1	 section 8	 cl. 3 of the American Constitution. " This part of the Constitution "	 observed Cardozo J.	 " was framed under the dominion of a political philosophy less parochial in range. It was framed upon the theory that the peoples of the several states must sink or swim together and that in the long run prosperity and salvation are in union and not division ". There is another general consideration which has been pressed before us by the learned Attorney General and the States to which reference must be made. It is argued that in determining the scope and reach of the freedom embodied in article 301 we should bear in mind the fact that to the extent to which the frontiers of this freedom are widened to that extent is the legislative power of the States curtailed or limited. The Legislatures of the States have plenary powers to (1) ; 	 523; 	 1038. 845 legislate in respect of topics covered by the legislative entries in Parts II and III. If the words used in article 301 receive the widest interpretation as contended by the appellants it would obviously mean that the State Legislatures would not be able to legislate on several entries in the said Lists without adopting the procedure prescribed by article 304(b). In fact it would be unreasonable to impose such a limitation on the legislative power of the State Legislatures and thereby affect their freedom of action. Whilst appreciating this argument it may be pertinent to observe that what appears as a curtailment of	 or limitation on	 the powers of the State Legislatures prescribed by article 304(b) day	 from the point of view of national economy	 be characterised as a safeguard deliberately evolved to protect the economic unity of the country ; even so it may be assumed that in interpreting the provisions of article 301 and determining the scope and effect of Part XIII we should bear in mind the effect of our decision on the legislative power of the States and also of Parliament. Having thus referred to some general considerations let us now proceed to examine the question as to whether tax laws are wholly outside the purview of Part XIII. In support of the argument that Part XIII does not apply to tax laws the learned Attorney General has emphasised the fact that the power to levy a tax is an essential part of sovereignty itself	 and he has suggested that this power is not subject to judicial review and never has been held to be so. In this connection he has invited our attention to the observa tions made in Cooley 's " Constitutional Limitations " on the power of taxation. 'The power to impose taxes "	 says the author	 " is one so unlimited in force and so searching in extent	 that the courts scarcely venture to declare that it is subject to any restriction whatever	 except such as rest in the discretion of the authority which exercises it " (1). The author then has cited the observations of Marshall	 C. J.	 in McCulloch vs Maryland (2) where the learned Chief Justice has (1) Cooley 's " Constitutional Limitations "	 Vol. 2	 8th Ed.	 p. 986. (2) ; 	 428: ; 	 607. 108 846 stated that " the power of taxing the people and their property is essential to the very existence of the government	 and may be legitimately exercised on the objects to which it is applicable to the utmost extent to which the government may choose to carry it. The only security against the abuse of this power is found in the structure of the government itself ". Basing himself on this character of the taxing power of the State the learned Attorney General has asked us to hold that Part XIII can have no application to any statute imposing a tax. In our opinion this contention is not wellfounded. The statement of the law on which reliance has been placed is itself expressed to be subject to the relevant provisions of the Constitution; for instance	 the same author has observed " It is also believed that that provision in the Constitution of the United States which declares that the citizens of each state shall be entitled to all the privileges and immunities of the citizens of the several states will preclude any state from imposing upon the property which citizens of other states may own	 or the business which they may carry on within its limits	 any higher burdens by way of taxation than are imposed upon corresponding property or business of its own citizens" (p. 1016). Putting the same propositions in terms of our Constitution it cannot be suggested that the power of taxation can	 for instance	 violate the equality before the law guaranteed by article 14 of the Constitution. Therefore the true position appears to be that	 though the power of levying tax is essential for the very existence of the government	 its exercise must inevitably be controlled by the constitutional provisions made in that behalf. It cannot be said that the power of taxation per se is outside the purview of any constitutional limitations. It is true that in Ramjilal vs Income tax Officer	 Mohindargarh (1) it has been held that " since there is a special provision in article 265 of the Constitution that no tax shall be levied or collected except by authority of law	 el. (1) of article 31 must be regarded as concerned with deprivation of property otherwise than by the (1) [1051] S.C.R. 127. 847 imposition or collection of tax	 and inasmuch as the right conferred by article 265 is not a right conferred by Part III of the Constitution	 it could not be enforced under article 32". It is clear that the effect of this decision is no more than this that the protection against the imposition and collection of taxes	 save by the authority of law	 directly comes under article 265 and cannot be said to be covered by cl. (1) of article 31. It would be unsafe to assume that this decision is	 or was intended to be	 an authority for the proposition that the levy of a tax by taxing statute can	 for instance	 violate article 14 of the Constitution. The next question which needs examination is whether tax laws are governed only by Part XII of the Constitution and not by Part XIII. The argument is that Part XII is a self contained code; it makes all necessary provisions	 and so the validity of any taxing statute can be judged only by reference to the provisions of the said Part. Article 265 provides that "no tax shall be levied or collected except by authority of law". It is emphasised that this Article does not contemplate that its provision is subject to the other provisions of the Constitution	 and so there would be no justification for applying Part XIII to the taxing statutes. It is also pointed out that restrictions and other exceptions which the Constitution wanted to prescribe in respect of taxation have been provided for by articles 274	 276	 285	 287 and 288	 and so we need not look beyond the provisions of this Part in dealing with tax laws. In our opinion this argument fails to take notice of the fact that article 265 itself inevitably takes in article 245 of the Constitution when in substance it says that a tax shall be levied by authority of law. The authority of law to which it refers and under which alone a tax can be levied is to be found in article 245 read with the corresponding legislative entries in Schedule VII. Now	 if we look at article 245 which deals with the extent of laws made by Parliament and by the Legislatures of States it begins with the words " subject to the provisions of this Constitution "; in other words	 the power of Parliament and the Legislatures of the States to make laws including 848 laws imposing taxes is subject to the provisions of this Constitution and that must bring in the application of the provisions of Part XIII. Therefore the argument based on the theory that tax laws are governed by the provisions of Part XII alone cannot be accepted. The power to levy taxes is ultimately based on article 245	 and the said power in terms is subject to the provisions of the Constitution. On the other hand	 the opening words of article 301 are very significant. The doctrine of the freedom of trade	 commerce and intercourse enunciated by article 301 is not subject to the other provisions of the Constitution but is made subject only to the other provisions of Part XIII; that means that once the width and amplitude of the freedom enshrined in article 301 are determined they cannot be controlled by any provision outside Part Xlll. This position incidentally brings out in bold relief the important part	 which the Constitution makers wanted the doctrine of freedom of trade to play in the future of the country. It is obvious that whatever may be the content of the said freedom it is not intended to be an absolute freedom; absolute freedom in matters of trade	 commerce and intercourse would lead to economic confusion	 if not chaos and anarchy; and so the freedom guaranteed by article 301 is made subject to the exceptions provided by the other Articles in Part XIII. The freedom guaranteed is limited in the manner specified by the said Articles but it is not limited by any other provisions of the Constitution outside Part XIII. That is why it seems to us that article 301	 read in its proper context and subject to the limitations prescribed by the other relevant Articles in Part XIII	 must be regarded as imposing a constitutional limitation on the legislative power of Parliament and the Legislatures of the States. What entries in the legislative lists will attract the provisions of article 301 is another matter; that will depend upon the content of the freedom guaranteed; but wherever it is held that article 301 applies the legislative competence of the Legislature in question will have to be judged in the light of the relevant Articles 849 of Part XIII; this position appears to us to be inescapable. On behalf of the respondent it was suggested before us that the scope and extent of the application of article 301 can well be determined in the light of section 297 of the Constitution Act of 1935. Section 297 reads thus: " 297(1). No Provincial Legislature or Government shall (a) by virtue of the entry in the Provincial Legislative List relating to trade and commerce within the Province	 or the entry in that List relating to the production	 supply	 and distribution of commodities	 have power to pass any law or take any executive action prohibiting or restricting the entry into	 or export from the Province of goods of any class or description ; or (b) by virtue of anything in this Act have power to impose any tax	 cess	 toll	 or due which	 as between goods manufactured or produced in the Province and similar goods not so manufactured or produced	 discriminates in favour of the former	 or which	 in the case of goods manufactured or produced outside the Province	 discriminates between goods manufactured or produced in one locality and similar goods manufactured or produced in another locality. (2) Any law passed in contravention of this section shall	 to the extent of the contravention	 be invalid. There is no doubt that the prohibition prescribed by this section was confined to the Provincial Governments and Provincial Legislatures and did not apply to the Central Government or Central Legislature. It is also true that the said prohibition had reference to the entries in the Provincial Legislative List relating to trade and commerce	 and to production	 supply and distribution of commodities. The section also deals with prohibitions and restrictions in respect of import of goods into	 or their export from	 a Province. Likewise discrimination against goods manufactured or produced outside the Province or goods produced in other localities is also prohibited. The argument 850 is that when the Constitution adopted article 301 it had section 297 in view and the only substantial change which it intended to make was to extend the application of the principles enunciated in the said section to the Union Government and the Union Parliament	 and to apply it to the territory which had subsequently become a part of India as indicated by the relevant 'Articles; the essential content of freedom of trade and commerce as prescribed by the said section	 however	 continues to be the same. In support of this argument	 reliance has been placed on the observations made by Venkatarama Aiyar	 J.	 in the case of M. P. V. Sundararamier & Co. vs The State of Andhra Pradesh (1). In that case the vires of some of the provisions of the Sales Tax Laws Validation Act	 1956 (7 of 1956)	 were challenged on several grounds. In dealing with one of the points raised in support of the said challenge Venkatarama Aiyar	 J.	 who delivered the majority judgment	 considered the content of Entry 42 in List 1. It had been urged before the Court that the said entry should be liberally construed and should be held to include the power to tax	 and in support of this contention reliance was placed on certain American and Australian decisions. This argument was repelled and it was held that Entry 42 in List I is not to be interpreted as including taxation. In coming to this conclusion the learned judge made certain general observations pointing out that it would not be always safe to rely upon American or Australian decisions in interpreting the provisions of our Constitution. Said the learned judge	 " the threads of our Constitution were no doubt taken from other Federal Constitutions but when they were woven into the fabric of our Constitution their reach and their complexion underwent changes. Therefore	 valuable as the American decisions are as showing how the question is dealt with in sister Federal Constitution great care should be taken in applying them in the interpretation of our Constitution ". He made a similar comment about section 92 of the Commonwealth of Australia Constitution Act and (1) ; 	 1483 84. 851 the decisions thereunder	 and in that connection he observed: '	 We should also add that article 304(a) of the Constitution cannot be interpreted as throwing any light on the scope of article 301 with reference to the question of taxation as it merely reproduces section 297(1)(b) of the Government of India Act	 and as there was no provision therein corresponding to article 301 section 297(1)(b) could not have implied what is now sought to be inferred from article 304(a) ". The learned Attorney General has relied on these observations. It would be noticed that	 incidental as these observations are	 what the learned judge was considering was the scope and effect of section 297(1)(b) of the Government of India Act	 1935	 and he held that the content of the said section cannot be enlarged in the light of the provisions of article 304(a). No doubt the observations would seem to show that the learned judge thought that article 304(a) cannot throw any light on the scope of article 301 with reference to the question of taxation ; but it is clear that the question of construing the said Articles did not fall to be considered	 and was not obviously argued before the Court. With respect	 it may be pointed out that in the happy phraseology adopted by the learned judge himself	 in the setting of Part XIII and particularly in the light of the wide words used in article 301	 the reach and complexion of article 304(a) is wider than section 297(1)(b) and does include reference to taxation. Then as to the merits of the argument that section 297 of the Constitution Act of 1935 should virtually determine the scope of article 301	 we are reluctant to accept the assumption that the only change which the Constitution makers intended to make by adopting article 301 was to extend the application of section 297 to the Union Government and the Parliament. Just as the Constitution makers had before them the said section they were also familiar with corresponding clauses included in the Federal Constitutions of other countries. The history of judicial decisions interpreting section 92 of the Australian Constitution must have been present to their minds as also the history of the growth and development of the American Law under 852 the commerce clause in the American Constitution. Besides	 we feel considerable hesitation in accepting the view that the makers of the Constitution did not want to enrich and widen the content of freedom guaranteed by section 297. They knew that the Constitution would herald a new and inspiring era in the history of India and they	 were fully conscious of the importance of maintaining the economic unity of the Union of India in order that the federal form of government adopted by the Constitution should progress in a smooth and harmonious manner. That is why we are inclined to hold that the broad and unambiguous words used in article 301 are intended to emphasise that the freedom of trade	 commerce and intercourse guaranteed was richer and wider in content than was the case under section 297; how much wider and how much richer can be determined only on a fair and reasonable construction of article 301 read along with the rest of the Articles in Part XIII. In our opinion	 therefore	 the argument that tax laws are outside Part XIII cannot be accepted. That takes us to the question as to whether article 301 operates only in respect of the entries relating to trade and commerce already specified. Before answering this question it would be necessary to examine the scheme of Part XIII	 and construe the relevant Articles in it. It is clear that article 301 applies not only to inter State trade	 commerce and intercourse but also intrastate trade	 commerce and intercourse. The words " throughout the territory of India " clearly indicate that trade and commerce whose free dom is guaranteed has to move freely also from one place to another in the same State. This conclusion is further supported by articles 302 and 304(b) as we will presently point out. There is no doubt that the sweep of the concept of trade	 commerce and intercourse is very wide; but in the present case we are concerned with trade	 and so we will leave out of consideration commerce and intercourse. Even as to trade it is really not necessary to discuss or determine what trade exactly means; for it is common ground that the activity carried on by the appellants 853 amounts to trade	 and it is not disputed that transport of goods or merchandise from one place to another is so essential to trade that it can be regarded as its integral part. Stated briefly trade even in a narrow sense would include all activities in relation to buying and selling	 or the interchange or exchange of commodities and that movement from place to place is the very soul of such trading activities. When article 301 refers to the freedom of trade it is necessary to enquire what freedom means. Freedom from what? is the obvious question which falls to be determined in the context. At this stage we would content ourselves with the statement that the freedom of trade guaranteed by article 301 is freedom from all restrictions except those which are provided by the other Articles in Part XIII. What these restrictions denote may raise a larger issue	 but in the present case we will confine our decision to that aspect of the matter which arises from the provisions of the Act under scrutiny. It is hardly necessary to emphasise that in dealing with constitutional questions courts should be slow to embark upon an unnecessarily wide or general enquiry and should confine their decision as far as may be reasonably practicable within the narrow limits of the controversy arising between the parties in the particular case. We will come back again to article 301 after examining the other Articles in Part XIII. article 302 confers on the Parliament power to impose restrictions on trade	 commerce and intercourse. It provides that Parliament may by law impose such restrictions on the freedom of trade	 commerce or intercourse between one State and another or within any part of the territory of India as may be required in the public interest. It would be immediately noticed that the reference made to a restriction on the freedom of trade within any part of the territory of India as distinct from freedom of trade between one State and another clearly indicates that the freedom in question covers not only inter State trade but also intrastate trade. Thus the effect of article 302 is to 109 854 provide for an exception to the general rule prescribed	 by article 301. Restrictions on the freedom of trade can be imposed by Parliament if they are required in the public interest so that the generality of freedom guaranteed by article 301 is subject to the exception s provided by article 302. That takes us to article 303. It reads thus: " 303. (1) Notwithstanding anything in article 302	 neither Parliament nor the Legislature of a State shall have power to make any law giving	 or authorising the giving of	 any preference to one State over another	 or making	 or authorising the making of	 any discrimination between one State and another	 by virtue of any entry relating to trade and commerce in any of the Lists in the Seventh Schedule. (2) Nothing in clause (1) shall prevent Parliament from making any law giving	 or authorising the giving of	 any preference or making	 or authorising the making of	 any discrimination if it is declared by such law that it is necessary to do so for the purpose of dealing with a situation arising from scarcity of goods in any part of the territory of India. " The first part of this Article is in terms an exception or a proviso to article 302 as is indicated by the nonobstante clause. This clause prohibits Parliament from making any law which would give any preference to one State over another or would make any discrimination between one State and another by virtue of the relevant entries specified in it. In other words	 in regard to the entries there specified	 the power to impose restrictions cannot be used for the purpose of giving any preference to one State over another or making any discrimination in that manner. It is obvious that the reference to the Legislature of the State in this clause cannot be reconciled with the non obstante clause; but the object of including the Legislature of a State appears to be to emphasise that like Parliament even the Legislature of a State cannot give any preference or make any discrimination. Sub Article (2) is an exception to sub article (1) of article 303. It empowers the Parliament to make a law giving or authorising to give any preference or making 855 any discrimination	 but this power can be exercised only if it is declared by law made by the Parliament that it is necessary so to do for the purpose of dealing with a situation arising from scarcity of goods in any part of the territory of India ; in other words	 it is only when Parliament is faced with the task of meeting an emergency created by the scarcity of goods in any particular part of India that it is authorised to make a law making a discrimination	 or giving preference	 in favour of the part thus affected. On behalf of the States strong reliance is placed on the fact that article 303(1) expressly refers to the entries relating to trade and commerce in any of the Lists in the Seventh Schedule	 and it is urged tbat this gives a clear indication as to the scope of the provisions of article 301 itself There is some force in this contention ; but on the whole we are not prepared to hold that the reference to the said entries should govern the construction of article 301. The setting in which the said entries are referred to would of course determine the scope and extent of the prohibition prescribed by article 303 (1); but that cannot be pressed into service in determining the scope of article 301 itself. It is significant that article 303(1) does not refer to intercourse and in that sense intercourse is outside its sphere. It is likely that having authorised Parliament to impose restrictions by article 302 it was thought expedient to prohibit expressly the said power of imposing restrictions from being used for the purpose of giving any preference in so far as the relevant entries are concerned. It may also be that the primary object of confining the operation of article 303(1) to the said entries was to introduce a corresponding limitation on the power of Parliament to discriminate under article 302. However that may be	 in our opinion the limitation thus introduced in article 303(1) cannot circumscribe the scope of article 301 or otherwise affect its construction. Besides	 as we will presently point out	 there are other Articles in this Part which indicate that tax laws are included within article 301	 and if that be so	 the reference to the said entries in article 303(1) cannot 856 limit the application of article 301 to the said entries alone. Article 304 reads thus: "Notwithstanding anything in article 301 or article 303	 the Legislature of a State may by law (a) impose on goods imported from other States or the Union territories any tax to which similar goods manufactured or produced in that State are subject	 so	 however	 as not to discriminate between goods so imported and goods so manufactured or produced; and (b) impose such reasonable restrictions on the freedom of trade	 commerce or intercourse with or within that State as may be required in the public interest: Provided that no Bill or amendment for the purposes of clause (b) shall be introduced or moved in the Legislature of a State without the previous sanction of the President. " The effect of article 304(a) is to treat imported goods on the same basis as goods manufactured or produced in any State; and it authorises tax to be levied on such imported goods in the same manner and to the same extent as may be levied on goods manufactured or produced inside the State. We ought to add that this sub Article assumes that taxation can be levied by the State Legislature on goods manufactured or produced within its territory and it provides that outside goods cannot be treated any worse. How a tax can be levied on internal goods is	 however	 provided by article 304(b). The non obstante clause referring to article 301 would go with article 304(a)	 and that indicates that tax on goods would not have been permissible but for article 304(a) with the non obstante clause. This incidentally helps to determine the scope and width of the freedom guaranteed under article 301 ; in other words article 304(a) is another exception to article 301. Article 304(b) empowers the State Legislature to impose reasonable restrictions on the freedom of trade with other States or within its own territory. Again	 the reference to the territory within the State supports the conclusion that article 301 covers the movement of 857 trade both inter State and intrastate. Article 304(b) is to be read with the non obstante clause relating to article 301 as well as article 303	 and in substance it gives power to the State Legislature somewhat similar to the power conferred on the Parliament by article 302. The reference to article 303 in the non obstante clause has presumably been made as a matter of abundant( caution since the Legislature of a State has been included in article 303(1). There are	 however	 obvious differences in the powers of the Parliament and State Legislatures. In regard to an act which the State Legislature intends to pass under article 304(b) no bill can be introduced without the previous sanction of the President	 and this requirement has obviously been inserted in order that regional economic pressures which may inspire legislation under the said clause should be duly examined in the light of the interest of national economy; such legislation must also be in the public interest which feature is common with the provision contained in article 302; such legislation must also satisfy the 'further test that the restrictions imposed by it are reasonable. That is another additional restriction imposed on the powers of the State Legislatures. Thus there are three conditions which must be satisfied in passing an Act under article 304(b)	the previous sanction of the President must be obtained	 the legislation must be in the public interest	 and it must impose restrictions which are reasonable. It is of course true that if the previous sanction of the President is not obtained that infirmity may be cured by adopting the course authorised by article 255. The result of reading article 304(a) and (b) together appears to be that a tax can be levied by a State Legislature on goods manufactured or produced or imported in the State and thereby reasonable restrictions can be placed on the freedom of trade either with another State or between different areas of the same State. Tax legislation thus authorised must therefore be deemed to have been included in article 301	 for that is the obvious inference from the use of the non obstante clause. Article 305 saves existing laws and laws providing 858 for State monopolies. It is unnecessary to deal with this Article. Its object clearly was not to interrupt or to Affect the operation of the existing laws except in so far as the President may by order otherwise direct. Article 306 is relevant. It reads thus: " Notwithstanding anything in the foregoing provisions of this Part or in any other provisions of this Constitution	 any State specified in Part B of the First Schedule which before the commencement of this Constitution was levying any tax or duty on the import of goods into the State from other States or on the export of goods from the State to other States may	 if an agreement in that behalf has been entered into between the Government of India and the Government of that State	 continue to levy and collect such tax or duty subject to the terms of such agreement and for such period not exceeding ten years from the commencement of this Constitution as may be specified in the agreement: Provided that the President may at any time after the expiration of five years from such commencement terminate or modify any such agreement if	 after consideration of the report of the Finance Commission constituted under article 280	 he thinks it necessary to do so." This Article has been subsequently deleted by section 29 and Schedule to the Constitution (Seventh Amendment) Act	 1956	 but its initial inclusion in Part XIII throws some light on the scope of article 301. Laws made by any State specified in Part B of the First Schedule levying any tax or duty on the import of goods into the State from other States or the export of goods from the State to other States were expressly saved by a article 306 because it was realised that they would otherwise be hit by article 301. In other words	 taxing statutes or statutes imposing duties on goods would	 but for article 306	 have attracted the application of article 301. Let us now revert to article 301 and ascertain the width and amplitude of its scope. On a careful examination of the relevant provisions of Part XIII as a whole as well as the principle of economic unity 859 which it is intended to safeguard by making the said provisions	 the conclusion appears to us to be inevitable that the content of freedom provided for by article 301 was larger than the freedom contemplated by section 297 of the Constitution Act of 1935	 and whatever else it may or may not include	 it certainly includes movement of trade which is of the very essence of all trade and is its integral part. If the transport or the( movement of goods is taxed solely on the basis that the goods are thus carried or transported that	 in our opinion	 directly affects the freedom of trade as contemplated by article 301. If the movement	 transport or the carrying of goods is allowed to be impeded	 obstructed or hampered by taxation without satisfying the requirements of Part XIII the freedom of trade on which so much emphasis is laid by article 301 would turn to be illusory. When article 301 provides that trade shall be free throughout the territory of India primarily it is the movement part of the trade that it has in mind and the movement or the transport part of trade must be free subject of course to the limitations and exceptions provided by the other Articles of Part XIII. That we think is the result of article 301 read with the other Articles in Part XIII. Thus the intrinsic evidence furnished by some of the Articles of Part XIII shows that taxing laws are not excluded from the operation of article 301 ; which means that tax laws can and do amount to restrictions freedom from which is guaranteed to trade under the said Part. Does that mean that all tax laws attract the provisions of Part XIII whether their impact on trade or its movement is direct and immediate or indirect and remote ? It is precisely because the words used in article 301 are very woe	 and in a sense vague and indefinite that the problem of construing them and determining their exact width and scope becomes complex and difficult. However	 in interpreting the provisions of the Constitution we must always bear in mind that the relevant provision " has to be read not in vacuo but as occurring in a single complex instrument in which one part may 860 throw light on another ". (Vide: James V. Commonwealth of Australia (1)). In construing article 301 we must	 therefore	 have regard to the general scheme of our Constitution as well as the particular provisions in regard to taxing laws. The construction of article 301 should not be determined on a purely academic or doctrinnaire considerations ; in construing the said 'Article we must adopt a realistic approach and bear in mind the essential features of the separation of powers on which our Constitution rests. It is a federal constitution which we are interpreting	 and so the impact of article 301 must be judged accordingly. Besides	 it is not irrelevant to remember in this connection that the Article we are construing imposes a constitutional limitation on the power of the Parliament and State Legislatures to levy taxes	 and generally	 but for such limitation	 the power of taxation would be presumed to be for public good and would not be subject to judicial review or scrutiny. Thus considered we think it would be reasonable and proper to hold that restrictions freedom from which is guaranteed by article 301	 would be such restrictions as directly and immediately restrict or impede the free flow or movement of trade. Taxes may and do amount to restrictions ; but it is only such taxes as directly and immediately restrict trade that would fall within the purview of article 301. The argument that all taxes should be governed by article 301 whether or not their impact on trade is immediate or mediate	 direct or remote	 adopts	 in our opinion	 an extreme approach which cannot be upheld. If the said argument is accepted it would mean	 for instance	 that even a legislative enactment prescribing the minimum wages to industrial employees may fall under Part XIII because in an economic sense an additional wage bill may indirectly affect trade or commerce. We are	 therefore	 satisfied that in determining the limits of the width and amplitude of the freedom guaranteed by article 301 a rational and workable test to apply would be: Does the impugned restriction operate directly or immediately on trade or its (1) 	613. 861 movement? It is in the light of this test that we propose to examine the validity of the Act under scrutiny in the present proceedings. We do not think it necessary or expedient to consider what other laws would be affected by the interpretation we are placing on article 301 and what other legislative entries would fall under Part XIII. We propose to confine our decision to the Act with which ' we are concerned. If any other laws are similarly challenged the validity of the challenge will have to be examined in the light of the provisions of those laws. Our conclusion	 therefore	 is that when article 301 provides that trade shall be free throughout the territory of India it means that the flow of trade shall run smooth and unhampered by any restriction either at the boundaries of the States or at any other points inside the States themselves. It is the free movement or the transport of goods from one part of the country to the other that is intended to be saved	 and if any Act imposes any direct restrictions on the very movement of such goods it attracts the provisions of article 301	 and its validity can be sustained only if it satisfies the requirements of article 302 or article 304 of Part XIII. At this stage we think it is necessary to repeat that when it is said that the freedom of the movement of trade cannot be subject to any restrictions in the form of taxes imposed on the carriage of goods or their movement all that is meant is that the said restrictions can be imposed by the State Legislatures only after satisfying the requirements of article 304(b). It is not as if no restrictions at all can be imposed on the free movement of trade. Incidentally we may observe that the difference in the provisions contained in article 302 and article 304(b) would prima facie seem to suggest that where Parliament exercises its power under article 302 and passes a law imposing restrictions on the freedom of trade in the public interest	 whether or not the given law is in the public interest may not be justiciable	 and in that sense Parliament is given the sole power to decide what restrictions can be imposed in public interest as 110 862 authorised by article 302. On the other hand article 304(b) requires not only that the law should be in the public interest and should have received the previous sanction of the President but that the restrictions imposed by it should also be reasonable. Prima facie the requirement of public interest can be said to be not justiciable and may be deemed to be satisfied by the sanction of the President; but whether or not the restrictions imposed are reasonable would be justiciable and in that sense laws passed by the State Legislatures may on occasions have to face judicial scrutiny. However this point does not fall to be considered in the present proceedings and we wish to express no definite opinion on it. Let us then examine the material provisions of the Act. As we have already pointed out the Act has been passed providing for the levy of tax on certain goods carried by roads or inland waterways in the State of Assam. Section 2(11) defines a producer as meaning a producer of tea and including the person in charge of the garden where it is produced. Section 3 is the charging section. It provides that manufactured tea in chests carried by motor vehicles etc.	 except railways and airways shall be liable to tax at the specified rate per lb. of such tea and this tax shall be realised from the producer. It also makes similar provisions for jute with which we are not concerned in the present proceedings. Section 6 provides for taxing authorities and their powers. Section 7 provides	 inter alia	 that every producer shall furnish returns of the manufactured tea carried in tea chests 	in such form and to such authority as may be prescribed. Section 8 makes a provision for licensing of balers who are persons owning or possessing pressing machines for the compression of jute into bales. Section 9 prescribes the procedure for levying the assessment ; and section 10 provides for the cancellation of assessment in the cases specified. Section 11 deals with the assessment in cases of evasion and escape; section 12 with rectification	 and section 13 with penalty for non submission of returns and evasion of taxes. Section 19 provides for notice of demand	 and is. 20 lays down when 863 tax becomes payable. This Act has been passed by the Assam Legislature under Entry 56 in List 11 and naturally it purports to be a tax on goods carried by roads or by inland waterways. It is thus obvious that the purpose and object of the Act is to collect taxes on goods solely on the ground that they are carried by road or by inland waterways within the area of the	 State. That being so the restriction placed by the Act on the free movement of the goods is writ large on its face. It may be that one of the objects in passing the Act was to enable the State Government to raise money to keep its roads and waterways in repairs; but that object may and can be effectively achieved by adopting another course of legislation ; if the said object is intended to be achieved by levying a tax on the carriage of goods it can be so done only by satisfying the requirements of article 304(b). It is common ground that before the bill was introduced or moved in the State Legislature the previous sanction of the President has not been obtained ; nor has the said infirmity been cured by recourse to article 255 of the Constitution. Therefore we do not see how the validity of the tax can be sustained. In our opinion the High Court was in error in putting an unduly restricted meaning on the relevant words in article 301. It is clear that in putting that narrow construction on article 301 the High Court was partly	 if not substantially	 influenced by what it thought would be the inevitable consequence of a wider construction of article 301. As we have made it clear during the course of this judgment we do not propose to express any Opinion as to the possible consequence of the view which we are taking in the present proceedings. We are dealing in the present case with an Act passed by the State Legislature which imposes a restriction in the form of taxation on the carriage or movement of goods	 and we hold that such a restriction can be imposed by the State Legislature only if the relevant Act is passed in the manner prescribed by article 304(b). This question can be considered from another point of view. When a State Legislature passes an Act under Entry 56 of List II its initial legislative 864 competence is not in dispute. What is in dispute is whether or not such legislative competence is subject to the limitations prescribed by Part XIII. Now what does an act passed under the said Entry purport to do ? It purports to put a restraint in the form of taxation on the movement of trade	 and if the movement of trade is regarded as an integral part of trade itself	 the Act in substance puts a restriction on trade itself. The effect of the Act on the movement of trade is direct and immediate; it is not indirect or remote; and so legislation under the said Entry must be held to fall directly under article 301 as legislation in respect of trade and commerce. In some of the decisions of this Court	 in examining the validity of legislation it has been considered whether the impugned legislation is not directly in respect of the subject matter covered by a particular Article of the Constitution. This test was applied	 for instance by Kania	 C. J.	 in the case of A. K. Gopalan vs The State of Madras (1). It was also adopted by this Court in the case of Ram Singh vs The State of Delhi (2). It is no doubt true that the points which arose for decision in those cases had reference to the fundamental rights guaranteed by articles 19	 21 or 22 ; but we are referring to those decisions in order to emphasise that the test there adopted would in the present case lead to the conclusion that the Act with which we are concerned is invalid. The true approach according to Kania	 C.J.	 is only to consider the directness of the legislation. Now	 if the directness of legislation has to be considered it is clear that the Act imposes a tax on the carriage of goods and that immediately takes it within the purview of Part XIII. In the course of arguments the learned Attorney General invited us to apply the test of pith and substance	 and he contended that if the said test is applied the validity of the Act can be sustained. In support of his argument he has relied on the observations made by Das	 C. J.	 in the case of The State of Bombay vs R.M.D. Chamarbaugwala (3). In that case the Court (1) (1950] S.C.R. 88. (2) ; (3) ; 865 was called upon to consider the validity of the Bombay Lotteries and Prize Competitions Control and Tax (Amendment) Act	 1952. The challenge to the Act proceeded on two grounds	 (1) that it violated the fundamental right guaranteed under article 19(1)(g) and (2) that it offended against the provisions of article 301. The challenge on the first ground was repelled because it was held that gambling cannot be treated as trade or business under article 19(1)(g). This conclusion was sufficient to repel also the other ground on which the	 validity of the Act was challenged because	 if gambling was not trade or business under article 19(1)(g)	 it was also not trade or commerce under article 301. On the conclusion reached by this Court that gambling is not a trade this position would be obvious. Even so	 the learned Chief Justice incidentally applied the test of pith and substance	 and observed that the impugned act was in pith and substance an act in respect of betting and gambling	 and since betting or gambling was not trade	 commerce or business " the validity of the Act had not to be decided by the yardstick of reasonableness and public interest laid down in articles 19(6) and 304 ". In this connection it may	 with respect	 be pointed out that what purports to be a quotation from Lord Porter 's judgment in Commonwealth of Australia & Ors. vs Bank of New South Wales(1) has not been accurately reproduced. In fact	 referring to phrases such as 'pith and substance ' Lord Porter has observed that " they no doubt raise in convenient form an appropriate question in cases where the real issue is one of subject matter	 as when the point is whether a particular piece of legislation is a law in respect of some subject within the permitted field. They may also serve useful purpose in the process of deciding whether an enactment which works some interference	 with trade	 commerce and intercourse among the States is nevertheless untouched by section 92 as being essentially regulatory in character " (pp. 312	 313). These observations would indicate that the test of pith and substance is generally and more appropriately applied when a dispute arises as to the 866 legislative competence of the legislature	 and it has to be resolved by reference to the entries to which the impugned legislation is relatable. When there is a conflict between two entries in the legislative lists	 and legislation by reference to one entry would be competent but not by reference to the other	 the doctrine of pith and substance is invoked for the purpose of determining the true nature and character of the legislation in question (Vide: Prafulla Kumar Mukherjee vs Bank of Commerce Ltd.	 Khulna (1) and Subrahmanyan Chettiar vs Muttuswami Goundan (2) . But even the application of the test of pith and substance yields the same result in the present proceedings. The pith and substance of the legislation is taxation on the carriage of goods and that clearly falls within the terms of article 301. At the commencement of this judgment we have stated that the complexity of the problem which we are called upon to decide in the present proceedings has been incidentally mentioned or considered in some of the reported decisions of this Court. We may in that connection refer to two of such decisions at this stage. In The State of Bombay vs The United Motors (India) Ltd. (3)	 Patanjali Sastri	 C. J.	 observed that the freedom of inter State trade and commerce declared in article 301 is expressly subordinated to the State power of taxing goods imported from sister States provided only no discrimination is made in favour of similar goods of local origin. According to the learned Chief Justice the commercial unity of India is made to give way before the State power of imposing any non discriminatory tax on goods imported from sister States. This observation would suggest that article 304(a) and (b) deal with taxes and to that extent it is inconsistent with the argument that tax laws are outside Part XIII. The next case in which this question has been incidentally discussed is in Saghir Ahmed vs The State of U. P. (4). In that case the impugned provisions of the U. P. Road Transport Act	 1951 (U. P. Act II of (1) (1947) L.R. 74 I.A. 23. (2) (3) ; (4) ; 867 1951)	 were declared to be unconstitutional on two other grounds which had no direct connection with the challenge under Part XIII of the Constitution. Even so	 Mukherjea	 J.	 as he then was	 who spoke for the Court	 has referred to the problem raised by Part XIII as " not quite free from difficulty " and has indicated its pros and cons which were urged before the Court. One of the points thus urged was that article 301 provides safeguards for carrying on trade as a whole as distinct from the rights of an individual to carry it on. In other words the said Article was concerned with the passage of commodities or persons either within or without the State frontiers but not directly with individuals carrying on the trade or commerce. The right of individuals	 it was said	 was dealt with under article 19(1)(g) so that the two Articles had been framed in order to secure two different objects. To the same effect are some of the observations made by Das	 C. J.	 in the case of R. M. D. Chamarbaugwala (1). It is unnecessary on the present occasion to consider whether the fields covered by article 19(1)(g) and article 301 can be distinguished in the manner suggested in the said observations. It may be possible to urge that trade as a whole moves inevitably with the aid of human agency	 and so protection granted to trade may involve protection even to the individuals carrying on the said trade. In that sense the two freedoms may overlap. However	 it is unnecessary to pursue this point any further in the present proceedings. Before we conclude we would like to refer to two decisions in which the scope and effect of the provisions of section 92 of the Australian Constitution came to be considered. We have deliberately not referred to these decisions earlier because we thought it would be unreasonable to refer to or rely on the said section or the decisions thereon for the purpose of construing the relevant Articles of Part XIII of our Constitution. It is commonplace to say that the political and historical background of the federal polity adopted by the Australian Commonwealth	 the setting of the Constitution itself	 the distribution of powers and the general scheme of the Constitution are different	 and so it (1) ; 868 would not be safe to seek for guidance or assistance from the Australian decisions when we are called upon to construe the provisions of our Constitution. In this connection we have already referred to the note of warning struck by Venkatarama Aiyar	 J.	 against indiscriminate reliance being placed on Australian and American decisions in interpreting our Constitution in the case of M. P. V. Sundararamier & Co. (1). The same caution was expressed by Gwyer	 C. J.	 as early as 1939 when he observed in The Central Provinces and Berar Sales of Motor Spirit and Lubricants Taxation Act	 1938 (2) " there are few subjects on which the decisions of other Courts require to be treated with greater caution than that of federal and provincial powers	 for in the last analysis the decision must depend upon the words of the Constitution which the Court is interpreting; and since no two Constitutions are in identical terms it is extremely unsafe to assume that a decision on one of them can be applied without qualification to another. This may be so even where the words or expressions used are the same in both cases	 for a word or a phrase may take a colour from its context and bear different senses accordingly ". Even so the reported decisions of this Court show that in dealing with constitutional problems reference has not infrequently been made to Australian and American decisions; and that	 we think	 brings out the characteristic feature of the working of the judicial process. When you are dealing with the problem of construing a constitutional provision which is none too clear or lucid you feel inclined to inquire how other judicial minds have responded to the challenge presented by similar provisions in other sister Constitutions. It is in that spirit that we propose to refer to two Privy Council decisions which dealt with the construction of section 92 of the Australian Constitution. The first paragraph of section 92 of the Australian Constitution	 around which has grown	 in the words of Lord Porter a " labyrinth where there is no golden thread "	 reads thus: " On the imposition of uniform (1) ; 1483 84. (2) 	 5. 869 duties of customs	 trade	 commerce	 and intercourse among the States	 whether by means of internal carriage or ocean navigation	 shall be absolutely free ". The part played by Frederick Alexander James	 who carried on the trade of growing and processing dried fruits	 in securing judicial pronouncements on the true scope and effect of the said section is wellknown. He fought three valiant legal battles in which he successfully asserted his right as a trader against legislative encroachment. In James V. State of South Australia (1) section 20 of the Dried Fruits Export Control Act	 1924	 was struck down. In James V. Cowan (2) section 28 was challenged	 whereas in the last case of James V. Commonwealth of Australia (3) James had claimed a declaration that the Dried Fruits Act 11 of 1928 and 5 of 1935 and the regulations framed thereunder were invalid as offending against section 92 of the Constitution. It is to the observations made by the Privy Council in the last case to which we wish to refer. Referring to the word " free " used in the said section Lord Wright observed that the said word in itself is vague and indeterminate; it must take its colour from the context. Then he referred to the fact that " 'free trade ' ordinarily means freedom from tariffs "	 but he immediately added that " free " in section 92 cannot be limited to freedom in the last mentioned sense. According to this judgment	 every step in the series of operations which constitute the particular transaction is an act of trade	 and control under the State law of any of these steps must be an interference with its freedom as trade. In this connection it was also observed that not much help is to be got by reflecting that trade may still be free though the trader has to pay for the different operations such as tolls	 railway rates and so forth; it would thus appear that the result of this decision is that imposition of tolls	 railway rates and so forth might impede the freedom of trade contemplated by section 92	 which in other words supports our conclusion that a tax may amount to a restriction under article 301. (1) ; (3) 	613. (2) III 870 In the case of Commonwealth of Australia vs Bank of New South Wales (1) to which reference has already been made in connection with the test of pith and substance the Privy Council was examining the validity of section 46 of Banking Act (Commonwealth) (No. 57 of 1947) in the light of the provisions of section 92 of the Australian Constitution. In deciding the said question one of the tests which was applied by Lord Porter was : " Does the act not remotely or incidentally (as to which they will say something later) but directly restrict the inter State business of banking "	 and he concluded that " two general propositions may be accepted	 (1) that regulation of trade	 commerce and intercourse among the States is compatible with its absolute freedom	 and (2) that section 92 is violated Only when a	 legislative or executive act operates to restrict such trade	 commerce and intercourse directly and immediately as distinct from creating Some indirect or consequential impediment which may fairly be regarded as remote ". This decision thus justifies the conclusion we have reached about the scope and effect of article 301. In the result we hold that the Act has put a direct restriction on the freedom of trade	 and since in doing so it has not complied with the provisions of article 304(b) it must be declared to be void. In view of this conclusion it is unnecessary to consider the other points urged in support of the challenge against the validity of the Act. The three appeals and the two petitions are accordingly allowed and writs or orders directed to be issued as prayed. The appellants and the petitioners will be entitled to their costs from the respondent. The validity of the Assam Taxation (on Goods carried by Roads or lnland Waterways) Act	 1954 hereinafter referred to as the	 Act	 is challenged by certain producers of tea in the States of West Bengal and Assam. The Act was passed by the Assam Legislature and received the assent of the Governor of Assam on April 9	 1954. To the introduc tion of the Bill (which was enacted into the Act) in 871 the State Legislature	 the previous sanction of the President was not obtained : nor did the President assent to the Act. By section 3 of the Act		 it is provided inter alia that " manufactured tea in chests carried by motor vehicles	 cart	 trolly	 boat	 animal and human agency or any other means except	 railways and airways shall be liable to a tax of one anna per pound of such tea and this tax shall be realised from the producer". " Producer " is defined by section 2 cl. (2) as meaning a producer of tea and included a person in charge of the garden where tea is produced. By section 4	 tax is charged on the total net weight carried during the return period. Section 7 provides that every producer and dealer shall furnish a return of manufactured tea carried in chests. By section 23	 cl. (3)	 the Commissioner of Taxes is authorised to recover taxes and penalties due under the Act as arrears of land revenue. Sections 27 and 28 impose a duty upon the producers to maintain accounts in the forms prescribed under the Act and to preserve the same and to producer them whenever called upon	 to the Commissioner or other persons as may be appointed by the Government in that behalf The rules framed under the Act make it obligatory upon the producers to submit quarterly returns to the Superintendent of Taxes and to maintain the registers in the forms prescribed and failure to maintain registers is penalised. In exercise of the powers conferred by section 7	 sub section (3)	 the Commissioner of Taxes issued a notification in the Assam Government Gazette notifying for general information that returns under the Act and the Rules thereunder for the period between June 1	 1954 and September 30	 1954	 shall be furnished on or before October 30	 1954	 and for the subsequent quarters on or before the dates specified therein. Three producers who transported their tea by road or by inland waterways to Calcutta in the State of West Bengal challenged by petitions under article 226 of the Constitution filed in the High Court of Assam	 tile authority of the Legislature of the State of Assam to enact the Act on the plea that the Act violated the guarantee of freedom of trade	 commerce and intercourse under 872 article 301 of the Constitution. The High Court rejected the plea raised by the petitioners	 and against the orders passed	 three appeals with certificates of fitness under article 132 of the Constitution have been preferred. Two other producers have challenged the vires of the Act by petitions under article 32 of the Constitution presented to this court. The principal question canvassed in these proceedings is about the competence of the Assam Legislature to enact the Act. The producers contend that by article 301 of the Constitution	 trade	 commerce and intercourse being declared free throughout the territory of India	 the statute authorising imposition of restrictions or burdens on that freedom by levying tax under the authority of an Act which does not conform to the conditions prescribed by the Constitution is invalid. Item 56 of List II of the seventh schedule to the Constitution authorises the State Legislature to impose taxes on goods and passengers carried byroad or on inland waterways. In terms	 the tax imposed by the Act is a tax on goods carried by road and inland waterways and is not of the nature of a duty of excise. If the vires of the Act are to be adjudged solely in the light of the power conferred by article 246 cl. (3) read with item 56 of List 11 of the seventh schedule	 the tax must be regarded as within the competence of the State. But the exercise of legislative power of the Parliament and the State Legislatures conferred by the legislative lists is restricted by diverse provisions of the Constitution. By article 301	 it is declared that subject to the provisions of Part XIII of the Constitution	 trade	 commerce and intercourse throughout the territory of India shall be free. The language of the Article is general; it admits of no implications and of no exceptions bar those expressly imposed by Part XIII. It comprehensively sets out the guarantee of freedom and defines in terms	 clear and precise	 that trade	 commerce and intercourse throughout the territory of India subject to the provisions of Part XIII	 shall be free	 i.e.	 trade	 commerce and intercourse shall not	 except to the extent expressly permitted	 be prohibited	 controlled	 burdened or impeded. Our 873 Constitution even though in form federal	 has in diverse provisions thereof	 emphasised the unity of India; and with a view to promote that unity appears to have guaranteed	 subject to specific restrictions	 freedom of trade	 commerce and intercourse throughout the territory. The Article is not merely declaratory of State policy like the directive principles defined by Part IV of the Constitution which are expressly not made enforceable by any court though the principles are " fundamental in the governance of the country '. It incorporates a restriction on the exercise of power by Governmental agency legislative as well as execu tive. Besides placing an irremovable ban on the executive authority	 it restricts the legislative power of the Parliament and the State legislatures conferred by articles 245	 246 and 248 and the relevant items in the legislative lists relating to trade	 commerce and intercourse. On the exercise of the legislative power to tax trade	 commerce and intercourse	 restrictions are prescribed by certain provisions Contained in Part XII	 e.g.	 articles 276	 286	 287	 288 and 289: but these restrictions do not exhaustively delimit the periphery of that power. The legislative power to tax is restricted also by the fundamental freedoms contained in Part III	 e.g.	 articles 14	15(1)	19(1)(g) and 31(1) and is further restricted by Part XIII. Article 245	 cl. (1)	 of the Constitution expressly provides that the legislative powers of the Parliament and the State Legisla tures to make laws are subject to the provisions of the Constitution ; and article 301 is undoubtedly one of the provisions to which the legislative powers are subject. The power of taxation is essentially an attribute of the sovereignty of the State and is not exercised in consideration of the protection it affords or the benefit that it confers upon citizens and aliens. Its content is not measured by the apparent need of the amounts sought to be collected	 and its incidence does not depend upon the ability of the citizens to meet the demand. But it is still not an unrestricted power. By article 265 of the Constitution	 the power to tax can be exercised by authority of law alone and the Constitution affirmatively grants the power of taxation 874 under diverse heads under the three lists of the seventh schedule. The power of taxation has there. fore to be exercised by the Legislature strictly within the limits prescribed by the Constitution	 and any alleged transgression either by Parliament or the State Legislature of the limits imposed by the Constitution is justiciable. Trade and commerce do not mean merely traffic in goods	 i. e.	 exchange of commodities for money or other commodities. In the complexities of modern conditions	 in their wide sweep are included carriage of persons and goods by road	 rail	 air and waterways	 contracts	 banking	 insurance transactions in the stock exchanges and forward markets	 communication of information	 supply of energy	 postal and telegraphic services and many more activities too numerous to be exhaustively enumerated which may be called commercial intercourse. Movement of goods from place to place may in some instance	% be an important ingredient of effective commercial intercourse	 but movement is not an essential ingredient thereof Dealings in goods and other commercial activities which do not import a concept of movement are as much part of trade and commerce as transactions involving movement of goods. The guarantee of freedom of trade and commerce is not addressed merely against prohibitions	 complete or partial; it is addressed to tariffs	 licensing	 marketing regulations	 price control	 nationalisation	 economic or social planning	 discriminatory tariffs	 compulsory appropriation of goods	 freezing or stand still orders and similar other impediments operating directly and immediately on the freedom of commercial intercourse as well. Every sequence in the series of operations which constitutes trade or commerce is an act of trade or commerce and burdens or impediments imposed on any such step are restrictions on the freedom of trade	 commerce and inter course. What is guaranteed is freedom in its widest amplitude freedom from prohibition	 control	 burden or impediment in commercial intercourse. Not merely discriminative tariffs restricting movement of goods are included in the restrictions which are hit by 875 Art 301	 but ball taxation on commercial intercourse	 even imposed as a measure for collection of revenue is so hit. Between discriminatory tariffs and trade barriers on the one hand and taxation for raising revenue on commercial intercourse	 the difference is one of purpose and not of quality. Both these forms of burden on commercial intercourse trench upon the freedom guaranteed by article 301: The guarantee of freedom is again not merely against burdens or impediments on inter State movement: nor does the language of article 301 guarantee freedom merely from restrictions on trade	 commerce and intercourse as such. Articles 302	 303	 304 and 306	 which I will presently advert to	 make it abundantly clear that the freedom contemplated was freedom of trade	 commerce and intercourse in all their varied aspects inclusive of all activities which constitute commercial intercourse and not merely from restrictions on " trade	 commerce and intercourse as such ". Article 301 as has already been observed enunciates a fetter upon the exercise of legislative power under the entries in the lists of the seventh schedule concerning or relating to trade	 commerce and intercourse. The basic principle underlying article 301 appears to have been adopted from the Constitution of the Australian Commonwealth. In the American Constitution	 by the 8th section	 article 1	 power to regulate commerce is granted; but the freedom of commerce as guaranteed by our Constitution is not found enunciated in the Constitution of the United States. Section 92 of the Constitution of the Commonwealth of Australia provides by the 1st paragraph that " on the imposition of uniform duties of customs	 trade	 commerce and intercourse among the States	 whether by means of internal carriage or ocean navigation	 shall be absolutely free ". That guarantee of freedom of trade	 commerce and intercourse though Dot as extensive as the guarantee enshrined in our Constitution	 is of the same pattern. But our Constitution has made a sig nificant departure from the Australian Constitution	 Whereas by section 92 of the Australian Constitution	 876 freedom of trade	 commerce and intercourse is guaranteed among the States	 i.e.	 at inter State level	 our Constitution has made trade	 commerce and intercourse free throughout the territory of India. The freedom guaranteed by our Constitution is more pervasive: it is freedom of trade	 commerce and intercourse intraState as well as inter State. But this extension of the area of its operation does not alter the content of that freedom. It is freedom from tax burdens as well as other impediments. Section 92 of the Commonwealth of Australia Act does not encompass the wide freedom guaranteed by our Constitution it protects trade	 commerce and intercourse from restrictions in inter State commerce; but in my judgment	 the interpretation put by the Judicial Committee of the Privy Council in James vs Commonwealth of Australia (1) upon the meaning of the expression " free " in section 92 is not on that account less illuminating in the interpretation of article 301 of our Constitution which is largely based on that section of the Australian Constitution. Lord Wright in delivering the judgment of the Board in James vs Commonwealth of Australia (1) (supra) at pp. 627.628 observed : " ' Free ' in section 92 cannot be limited to freedom in the last mentioned sense (freedom from tariffs). There may at first sight appear to be some plausibility in that idea	 because of the starting point in time specified in the section	 because of the sections which surround	 section 92	 and because proviso to section 92 relates to customs duties. But it is clear that much more is included in the term; customs duties and other like matters constitute a merely pecuniary burden; there may be different and perhaps more drastic ways of interfering with freedom	 as by restriction or partial or complete prohibition of passing into or out of the State. Nor does " free " necessarily connote absence of discrimination between inter State and intrastate trade. No doubt conditions restrictive of freedom of trade among the States will frequently 'involve a discrimination; but that is not essential or decisive. . (1) 877 A compulsory seizure of goods may include indifferently goods intended for intrastate trade and goods intended for trade among the States. Nor can freedom be limited to freedom from legislative control; it must equally include executive control Every step in the series of operations which constitute the particular transaction is an act of trade; and control under the State law of any of these steps must be an interference with its freedom as trade. " These observations made in the context of a guarantee against obstruction to the flow of interstate trade and commerce	 involved the " conception " of " freedom from customs duties	 imports	 border prohibitions and restrictions of every kind : the people were to be free to trade with each other	 and to pass to and fro among the States	 without any burden	 hindrance or restriction based merely on the fact that they were not members of the same State ". Freedom guaranteed by article 301 is however not absolute: it is subject to the provisions contained in Part XIII of the Constitution. Article 302 authorises Parliament to impose restrictions on the freedom of trade	 commerce and intercourse between one State and another or within any 'part of the territory of India as may be required in the public interest. The Constitution has therefore circumscribed the guarantee under article 301 by authorising the Parliament to impose restrictions thereon. Such restrictions on trade	 commerce and intercourse may be intrastate as well as inter State: the only condition which the restrictions must fulfil is that they must be imposed in the public interest. The learned Attorney General urged that the courts are incompetent to adjudge whether the quantum	 and the incidence of a tax imposed by a Legislature in exercise of its powers are in the public interest	 and therefore it must be inferred that articles 301 and 302 do not deal with freedom from taxation and the limits which may be placed thereon. Counsel urged that in the modern political thought	 exercise of the sovereign power of taxation is not restricted to collection of revenue for governmental 112 878 purposes; it is reported to for diverse purposes	 often with a view to secure a pattern of social order ensuring justice	 liberty and equality amongst citizens. That the courts may not in adjudging upon the validity of a restriction imposed by a parliamentary statute	 lightly enter upon an investigation whether the amount sought to be recovered and its incidence are in the public interest	 is not a ground for holding that article 302 does not deal with restrictions which may be placed upon trade	 commerce and intercourse by the imposition of taxes. The courts will normally rely upon the wisdom of the Parliament and presume that taxes are generally imposed in the public interest: but that does not exclude the jurisdiction of the court in a given case to enter upon an enquiry whether an impugned legislation satisfies the constitutional test. If an enquiry into the validity of a burden or impediment imposed on the freedom of trade	 commerce 'and intercourse imposed otherwise than by levying a tax is within the competence of the court	 the restraint which the courts put upon their own functions by raising a presumption of constitutionality in dealing with a burden imposed by a taxing statute cannot be forged into a fetter upon their jurisdiction. By el. (b) of article 304	 the State Legislatures are invested with similar authority to impose restrictions on the freedom of trade	 commerce and intercourse with or within the State as may be required in the public interest. The territorial extent of the operation of the laws which may be made under articles 302 and 304(b) may not from the very nature of the jurisdiction exercised by the Legislatures be co extensive	 but subject thereto	 the Parliament and the State Legislatures are entrusted in exercise of legislative authority with powers to restrict freedom of trade	 commerce and intercourse. Why the Constitution should have enacted that the Parliamentary law may impose restrictions as may be required in the public interest and the State law may impose reasonable restrictions as may be required in the public interest	 it is difficult to appreciate. It is unnecessary for the purpose of these cases to enter 879 upon a discussion whether there is any real distinction between the quality of restrictions which may be imposed by legislation by the Parliament and State Legislatures exercising authority respectively under articles 302 and 304(b) of the Constitution. The two Articles enact that to oirucmscribe effectively the freedom of trade	 commerce and intercourse	 the restriction must satisfy the primary test that it is " required in the public interest ". Clause (b) of article 304 is subject to a proviso that no Bill or amendment for the purpose of el. (b) shall be introduced or moved in the Legislature of a State without the previous sanction of the President. The authority of the State Legislature to enact legislation imposing restrictions on trade	 commerce and intercourse is therefore subject to the condition that before the Bill or amendment of a statute is moved	 the previous sanction of the President must be obtained. Legislative power of the Parliament imposing restrictions on the freedom of trade	 commerce and intercourse may therefore be validly exercised if the restrictions are required in the public interest. On the exercise of authority in that behalf by the State Legislatures	 there are placed two restrictions	 (1) that the restriction must be reasonable and required in the public interest	 (2) that the Bill or amendment imposing restriction can be moved or introduced in the Legislature only with the previous sanction of the President. In this context	 I may refer to article 255 which provides	 in so far as it is material	 that no Act of the Legislature of a State shall be invalid by reason only that the previous sanction required by the Constitution was not given	 if assent to that Act was given under el. (c) where the previous sanction required was that of the President	 by the President. Even if the previous sanction of the President has not been obtained to the moving or introduction of the Bill or amendment falling within el. (b) of article 304	 the Act still would not be invalid if the President has signified his assent to the Act enacted by the Legislature. Article 303(1) is an exception to article 302 as well as article 304(b). Notwithstanding the wide sweep of the 880 legislative power restored by articles 302 and 304(b) to the Parliament and the State Legislatures to make laws imposing restrictions on the freedom of trade	 commerce and intercourse	 prohibition is imposed on the exercise of the power in making laws giving or authorising the giving of	 any preference to one State over another or making	 or authorising the making of	 any discrimination between one State and another	 by virtue of any entry relating to trade and commerce in any of the Lists in the seventh schedule. (1) of article 303 emphasises the object of the Constitution. makers to safeguard the economic unity of the nation and to prevent discrimination between the constituent States in the matter of trade and commerce. It is true that under cl. (1) of article 302	 the discrimination which is prohibited is under a law made by virtue of an entry relating to trade and commerce in the seventh schedule. But thereby	 discrimination which is prohibited is not limited to discrimination under laws made under items expressly relating to the trade and commerce items of the seventh schedule. The expression " relating to trade and commerce " used in article 302(1) in my judgment includes all those entries in the lists of the seventh schedule which deal with the power to legislate	 directly or indirectly in respect of activities in the nature of trade and commerce. By el. (2) of article 303	 the rigour of cl. (1) in the matter of laws to be enacted by Parliament is to a certain extent reduced. That clause authorises the Parliament	 but not the State Legislatures	 to make laws notwithstanding el. (1) when it is declared by law that it is necessary to make discrimination which is prohibited for the purpose of dealing with the situation arising from scarcity of goods in any part of the territory of India. Article 304	 in so far as it is material	 provides that notwithstanding anything in article 301 or article 303	 the Legislature of a State may by law	 (a) impose on goods imported from other States (or the Union territories) any tax to which similar goods manufactured or produced in that State are subject	 so	 however	 as not to discriminate between goods so imported and goods so 881 manufactured or produced. This clause implies that notwithstanding anything contained in article 301 or article 303	 the State Legislature has the power to im. pose tax on the import of goods to which similar goods manufactured or produced in the State are subject	 provided that by taxing the goods imported from another State or Union territory	 no discrimination is practised. If article 301 and article 303 did not deal with restrictions or burdens in the nature of tax	 the reason for incorporating the non obstante clause to which article 304	 el. (1)	 is subject	 cannot be appreciated. Undoubtedly	 the provisions of Part XIII of the Constitution do not impose additional or independent powers of taxation; the powers of taxation are to be found conferred by articles 245	 246 and 248 read with the lists in the seventh schedule	 and the provisions of Part XIII are limitative of the exercise of legislative power. The circumstance that the Constitution has chosen to deal with a specific field of taxation as an exception to articles 301 and 303 (which should really be article 303(1) ) strongly supports the inference that taxation was one of the restrictions from the imposition of which by the guarantee of article 301	 trade	 commerce and intercourse are declared free. Clause (b) of article 304 is subject to the proviso prescribing that the previous sanction of the President shall be obtained to the moving or introduction of a Bill or amendment imposing restrictions on the freedom of trade	 commerce and intercourse. There is however no such condition imposed in the matter of enactment of laws imposing non discriminative tariffs under el. But on that account	 the nature of the restrictions contemplated by cls. (a) arid (b) is not in any manner different. Clause (b) deals with a general restriction which includes a restriction by the imposition of a burden in the nature of tax. Clause (a) deals with a specific burden of taxation in a limited field. Article 305 protects existing laws except in so far as the President may by order or otherwise direct	 and it also validates certain enactments made before the commencement of the Constitution (Fourth Amendment) Act	 1955	 and authorises the Parliament 882 and the State Legislatures in future to make laws relating to matters referred to in sub cl. (2) of cl. (6) of article 19. Article 306 of the Constitution which was repealed by the Constitution (Seventh Amendment) Act	 1956	 provided	 in so far as it is material	 that notwithstanding anything in the foregoing provisions of Part XIII or any other provisions of the Constitution	 a State specified in Part B of the First Schedule which before the commencement of the Constitution was levying any tax or duty on the import of goods into the State from other States or on the export of goods from the State to other States may	 if an agreement in that behalf has been entered into between the Government of India and the Government of that State continue to levy and collect such tax or duty subject to the terms of such agreement. . . The marginal note of the Article refers to the power of the States specified in Part B of the First Schedule to levy tax as a power to impose restrictions on trade and commerce	 and clearly supports the view that within the meaning of article 301	 freedom was to include free dom from taxation and the restrictions contemplated by articles 302 and 304 contemplated imposition of burdens of the nature of taxation. On a careful review of the various Articles	 in my judgment	 by Part XIII	 restrictions have been imposed upon the legislative power granted by articles 245	 246 and 248 and the lists in the seventh schedule to the Parliament and the State Legislatures and those restrictions include burdens of the nature of taxation. Therefore	 the power to tax commercial intercourse vested by the legislative lists in the Parliament or the State Legislatures	 is circumscribed by Part XIII of the Constitution and if the exercise of that power does not conform to the requirements of Part XIII	 it would be regarded as invalid. As observed hereinbefore	 the previous sanction of the President was not obtained to the moving of the Bill which was enacted as the impugned Act. Even though the Assam Legislature had by item 56 of the seventh schedule legislative authority to impose this tax	 the State could not exercise this authority in the absence of the previous sanction of the President and 883 the invalidity of the Act imposing the tax on goods and passengers is not cured	 the President not having assented to the Act at any time after it was passed by the Assam Legislature. The argument that this view seriously restricts the " sovereignty " of the States has	 in my view	 little force. Even a cursory review of our constitutional provisions clearly shows that the primary object of the Constituent Assembly was to erect a governmental machinery with a strong central Government	 with the object of building up a healthy economy	 and unifying the various component States	 consisting of the former British Indian Provinces and the merged Indian States	 by subordinating local and parochial interests to the wider national interest. In any event	 in adjudging the vires of a statute	 the impact of the view which the interpretation placed by the court may produce on some cherished notion of sovereignty of the component States must be ignored. In that view	 the Assam Taxation (on Goods carried by Roads or Inland Waters) Act	 1954	 must be regarded as infringing the guarantee of freedom of trade and commerce under article 301	 because the Bill moved in the Assembly had not received the assent of the President as required under article 304(b) proviso	 and the Act has not been validated by the assent of the President under article 255(c). In the view expressed by me	 I do not deem it necessary to enter upon certain subsidiary contentions such as the application of the " pith and substance doctrine " to the interpretation of the relevant clauses	 the alleged violation by the Act of the equal protection clause of the Constitution	 and the effect of Act XXIX of 1953 enacted by the Parliament	 which were debated at the Bar. In the view taken	 the appeals must be allowed and the Rule in the two applications made absolute	 with costs. ORDER OF COURT: In view of the majority judgment	 the appeals and the writ petitions are allowed with costs one set of hearing fees.

The Assam Taxation (on goods carried by Roads and Inland Waterways) Act	 1954	 was passed under Entry 56 of List II of Seventh Schedule to the Constitution. The appellants contended that the Act violated the freedom of trade guaranteed by article 301 Of the Constitution and as it was not passed after obtaining the previous sanction of the President as required by article 304(b) it was ultra vires. The respondent urged that taxing laws were not governed by Part XIII (which contained articles 301 and 304) but only by Part XII and in the alternative that the provisions of Part XIII applied only to such legislative entries in the Seventh Schedule as dealt specifically with trade	 commerce and intercourse. Held	 (per Gajendragadkar	 Wanchoo and Das Gupta	 JJ.) that the Act violated article 30i and since it did not comply with the provisions of article 304(b) it was ultra vires and void. The freedom of trade	 commerce and intercourse guaranteed by article 301 was wider than that contained in section 297 Of the Government of India Act	 1935	 and it included freedom from tax laws also. Article 301 provides that the flow of trade shall run smooth and unhampered by any restriction either at the boundaries of the States or at any other points inside the States themselves ; and if any Act imposes any direct restrictions on the movement of goods it attracts the provisions of article 301	 and its validity can be sustained only if it satisfied the requirements of article 302 or article 304. The operation of article 301 cannot be restricted to legislation under the Entries dealing with trade and commerce. The Assam Act directly affected the freedom contemplated by article 301.

Per Sinha	 C. J. The Assam Act did not contravene article 301 and was not ultra vires. Neither the one extreme position that article 301 included freedom from all taxation nor the other that taxation was wholly outside the purview of article 301 was correct. The freedom conferred by article 301 did not mean freedom from taxation simpliciter but only from the erection of trade barriers	 tariff walls and imposts which had a deleterious effect on the free flow of trade	 commerce and intercourse. The Assam Act was a taxing statute simpliciter and did not suffer from any of the vices against which Part XIII of the Constitution was intended. Ramjilal vs Income tax Officer	 Mohindargarh	 [1951] S.C.R. 127	 referred to. Further	 the impugned Act was within the competence of the State Legislature and fell directly within Entry 56 of List 11 ; it was not in conflict with the Tea Act Of 1953 enacted by Parliament; it did not contravene article 14 and it was not extra territorial in operation. The Tata Iron & Steel Co. Ltd. vs The State of Bihar	 ; 	 followed. Per Shah	 J. The Assam Act infringed the guarantee of freedom of trade and commerce under article 301 and as the Bill was not moved with the previous sanction of the President as required by article 304(b) nor was it validated by the assent of the President under article 255(c)	 it was ultra vires and void. Article 301 guarantees freedom in its widest amplitude	 freedom from prohibition	 control	 burden or impediment in commercial intercourse. The freedom includes not only freedom from discriminative tariffs and trade barriers but also from all taxation on commercial intercourse. Part XIII of the Constitution places restrictions upon the legislative power granted by articles 245	 246 and 248 and the Lists and these restrictions include burdens in the nature of taxation.
