Maheshwari & Suresh Seth for the Appellant (In CA No. 336/70). M. Veerappa	 for the respondent (In C.A. No. 336/70). The Judgment of the Court was delivered by JAGANMOHAN REDDY	 J. These appeals raise a common question :as to whether Dumpers	 Rockers and Tractors are motor vehicles within the meaning of the relevant State Motor Vehicles Taxation Acts	 and are accordingly taxable thereunder. Apart from these appeals	 Bolani Ores Ltd. Appellant in Civil Appeal No. 1816 of 1968 has filed a writ petition challenging the constitutional validity of the Bihar and Orissa Motor Vehicles Taxation Act	 1930. The question raised in the writ petition will only arise for determination	 if the judgment of the High Court of Orissa is held to be valid otherwise the question of the constitutional validity of the Bihar and Orissa Motor Vehicles Taxation Act (hereinafter referred to as 'the Taxation Act ') does not fall for determination as that would be purely academic. The two Civil Appeals Nos. 1816 of 1968 and 1817 of 1968 arise out of two suits One filed by Bolani Ores Ltd. and the other by Orissa Minerals Development Company Ltd.	 respectively	 for a declaration that the machineries in their possession which were described in the respective Schedules to the plaints were not liable for registration under section 22 of the Indian Motor Vehicles Act hereinafter referred to as 'the Act '	 and cannot	 therefore	 be taxed under section 6 of the Taxation Act. In the suit filed by Bolani Ores Ltd.	 8 types of machinery were involved : (1) Shovels	 (2) Drill Master	 (3) Caterpillar Bulldozers	 (4) Rockers	 (5) Dumpers	 (6) Motor Grader	 (7) Tractors and (8) Fargo Truck fitted with serving tank for diesel oil etc. The 'Trial Court held that all the items of machinery as above mentioned	 except item (6) i.e. Motor Grader	 came within the definition of a 141 motor vehicle ' given in section 2 (18) of the Act	 and were therefore liable for registration under section 22 of the Act as well as payment of taxes under the Taxation Act. Against this decision	 First Appeal No. 44 of 1963 was filed in the Orissa High Court. The State did not file any cross appeal against the declaration that item (6) was not taxable. The High Court was of the view that unless it is shown that the vehicle is of a special type adapted for use only in factories or enclosed premises and incapable of running on any other type of roads or public roads	 the vehicles were motor vehicles. It was conceded during the hearing on behalf of the appellant that type (8) Fargo Truck clearly comes within the definition of motor vehicle and likewise the Advocate General conceded that type (2) Ingersoll Hand Drill Master cannot be held to be a Motor Vehicle. The High Court accordingly modified the order of the Trial Court in respect of the types in items (1)	 (2) and (3). It held that these three types as well as the Motor Grader in item (6) already held by the Trial Court not to be a motor vehicle	 were not liable for registration under section 22 of the Act	 nor would they be subject to payment of tax under the Taxation Act. In the suit filed by Orissa Mineral Development Company Ltd.	 out of which First Appeal No. 45 of 1963 arose	 the plaintiff sought a declaration that nine types of machinery which it owns were not liable for registration under the Act : Item (1) & (2) being Dumpers	 (3)& (3A) Tractors (4) Caterpillar Trax Cavetror	 (5) & (6) Caterpillar Bull dozers: (7) & (8) Scrapers and (9) Shovel. The Trial Court found on evidence that items (4) to (9) had a sort of crawler mechanism and were not adapted for regular use on the roads. This fact was also admitted by the opposite party. Accordingly it held that the vehicles in these Items did not come within the ambit of the definition of. 'motor vehicle ' under section 2(18) and were not liable for registration under section 22 of the Act. The case of Dumpers and Tractors items (1) to (3) and (3A)	 however	 was held to stand on a different footing	 as these vehicles were adapted for being used on roads for transporting the goods of the plaintiffs though it may be within its own field of operation. The reasons for bringing such vehicles and the tractors within the purview of section 2(18) of the Act were discussed at some length	 and accordingly it was held in both the suits that the vehicle indicated in the respective suit were liable for registration under section 22 of the Act and for payment of the requisite tax under the Taxation Act. In these appeals intervention of M/s. Chougle & Co.	 M/s N.C.D.C. Ltd. and 'M/s. Dalmia Cement Ltd. who allege that proceedings taken by them are pending in Courts	 was permitted and they are represented by the learned Advocates Soli J. Sorabji	 section P. Nayar and section T. Desai respectively. Civil Appeal No. 336 of 1970 is in respect of the Mysore Motor Vehicles Taxation Act hereinafter called 'the Mysore Act '. The appellants in this appeal filed a petition under article 226 of the Constitution in the High Court of Mysore challenging the demand by the Regional Transport Officer to get the Dumpers registered under the Act failing which they would be committing an offence entailing penal 142 consequences. The High Court of Mysore	 while dismissing the petition	 held that the Dumpers can be used for carrying loads even outside the mining area or any other enclosed premises	 like any other 'goods vehicle ' which is required to be registered under the Act. According to it	 what would take the vehicle out of the category of 'motor vehicles ' under the Mysore Act is that they must be such as "are capable of use in any other place for the purpose of transport of goods or passengers"	 which	 in its view	 was not "the same thing as saying that if the vehicle is not put to use elsewhere	 or used for a special purpose	 it must be exempted from registration under section 22 of the Act. " It further observed : "The test of purpose	 as argued by the learned counsel	 does not also	 in our view fall clearly within the purview of the statutory "exemption in section 2(18) of the Act. On the other hand	 what is enjoined is that its very design and manufacture must be such as would confine its capability for use only in a factory or enclosed premises	 Referring to the case of M/s. Bolani Ores Ltd. vs State of Orissa, (1) the interpretation placed by the Orissa High Court on the judgment of the Supreme Court in The State of Mysore vs Syed lbrahim(2) was not accepted. On this aspect of the Mysore High Court observed : But	 it may also be noted that in the decision of the Supreme Court	 above referred to	 what was in question was whether the owner of a Motor Car	 which was used for transporting passengers for hire was liable for prosecution under section 42(1) of the Act. The exemption under section 2(18) did not fall for consideration in the said decision. It was in this context that the Supreme Court laid down that if a Motor Vehicle is used as a transport vehicle	 the owner who so uses it or permits it to be so used is required to obtain the necessary permit. It is the use of the vehicle for carrying passengers for hire or reward which determines the application of section 42(1) of the Act. " The_High Court	 however	 agreed with the test laid down by the Orissa High Court for determining what under the is a 'motor vehicle '. The decision in these appeals hinges on the view we take of what a 'motor vehicle ' is for the purpose of section 2(c) of the Taxation Act under which the motor vehicle has the same meaning as in the 	 and whether the subsequent amendment of the definition in section 2(18) of the Act by the Motor Vehicles (Amendment) Act	 will govern the definition of 'motor vehicle ' for the purposes of the Taxation Act. Section 6 of the Taxation Act imposes on every motor vehicle a tax at the rate specified in the Second Schedule to the Act. The question	 therefore	 arises as to what is a 'motor vehicle ' for the purposes of the Taxation Act. It may be pointed out that section 2(c) of the Taxation Act	 prior to its amendment in 1940	 defined a 'motor vehicle ' as meaning any vehicle propelled	 or which may be propelled	 on a road by electrical or mechanical power either entirely (1) A. I.R.1958 Orissa 1. (2) 3. 143 or partially. In 1939 the of 1914 was repealed and a new Act substituted in its place. The 1914 Act defined 'motor vehicle ' as including "a vehicle	 carriage or other means of conveyance propelled	 or which may be propelled	 on a road by electrical or mechanical power either entirely or partially." The Orissa Act	 therefore	 initially adopted the definition in the Taxation Act	 which was in consonance with the 	 as it then stood. The definition of 'motor vehicle ' under section 2(18) of the Act having been redefined	 the Taxation Act by the Orissa Amendment Act 2 of 1940 adopted that definition for the purposes of taxation. The preamble to this amendment stated that the amendment was made for the purpose of avoiding repugnancy in the . The Orissa Amendment Act of 1943 reenacted provisions of sections 2 to 8 of the said Act	 as the Amendment Act 2 of 1940 was due to expire on November 23	 1943. Section 2(18) of the Act was	 however	 amended by Act 100 of 1956 but there was no corresponding amendment in the definition of section 2(c) of the Taxation Act. It is	 therefore	 contended that the amended definition is inapplicable 'Lo the Taxation Act	 but it is only the definition of a 'motor vehicle ' as it existed under the Act prior to the amendment that has to be read in section 2(c) of the Taxation Act	 inasmuch as the purpose and intendment of the Legislature was only to incorporate the definition as it existed at the time when the Taxation Act was amended in 1943. If it was otherwise	 following the legislative practice adopted earlier by the Orissa Legis lature	 the definition of a 'motor vehicle ' would have been suitably amended in order to avoid any repugnancy with the amendment. Apart from this contention	 it is also submitted that under the definition as it existed prior to the amendment or subsequent thereto dumpers	 rockers and tractors are not 'motor vehicles '	 because they are not adapted for use on the road. Before we deal with this question it is necessary to note the preliminary objection raised by the learned Advocate for the State of Orissa that the appellants should not be permitted to raise this question as it was not pleaded or urged either before the Trial Court or before the High Court	 nor is there any evidence to determine the question whether the vehicles	 on which the levy of the impugned tax is held to be valid	 are used solely upon the premises of the owners. It is submitted that the contention is contrary to what is stated in the plaint and that it is also not covered by any of the issues under which the question as to whether the premises in which the plaintiffs operate are the exclusive premises of the plaintiffs	 nor is there any evidence as to whether the area where the vehicles operate is the exclusive area of the plaintiffs. In our view	 the preliminary objection has no validity	 because	 firstly	 in para 2 of the plaint it is definitely pleaded : "That for the specific purpose of mining operations within their leasehold areas	 they possess Caterpillar Bulldozers Model D.S. Letourneau Westinghouse Dumpers and Euclid Dumpers Motor Grader Tractors. Fargo Truck" etc. "These machines are mechanically propelled but are neither intended nor adapted for use on public roads nor are ever used by the plaintiffs on public roads or public places." Secondly	 144 the relief asked for is that the machines in possession of the plaintiffs as described above for the purpose of working in the mines and removing over burdens are not liable for registration and consequent payment of taxes under the Taxation Act. Thirdly	 the written statement clearly comprehends what the plaintiffs ' case is. It is categori cally stated in para 4 that "the various types of machines enumerated in para 2 of the plaint being mechanically propelled vehicles come within the definition of motor vehicles as contained in section 2(18) of the Act since they do not come under the exceptions provided therein. It is incorrect to say that these vehicles are neither intended nor adapted for use on public roads	 nor are ever so used by the plaintiffs on public roads or public places. On the contrary the places where the aforesaid machines are operating are public places within the meaning of section 2(24) of the since the public are granted the right of access to the same for transacting day to day business. " Fourthly	 issues Nos. 4 and 5	 viz. "Are the suit vehicles not 'motor vehicles ' within the provisions of ?" and "Are the suit vehicles liable for registration and taxation? respectively give scope for the question now raised. Lastly	 the evidence also which has been led by the plaintiffs	 and to which we shall have occa sion to refer later entitles the appellants to raise this question. For these reasons	 we reject the preliminary objection. It is now necessary to compare the two definitions of 'motor vehicle ' under section 2(18) of the Act both before and after the amendment by Act 100 of 1956. We	 therefore	 give below both these definitions Section 2 (18) before amendment. motor vehicle" means any mechanically propelled vehicle adapted for use upon roads whether the power of propulsion is transmitted thereto from an external or internal source and includes a chassis to which a body has not been attached and a trailer; but does not include a vehicle running upon fixed rails or used solely upon the premises of the owner. Section 2 (18) after amendment by Act 100 of 1956 "motor vehicle" means any mechanically propelled vehicle adapted for use upon roads whether the power of propulsion is transmitted thereto from an external or internal source and includes a chassis to which a body has not been attached and a trailer; but does not include a vehicle running upon fixed rails or a vehicle of a special	 type adapted for use only in a factory or in any other enclosed premises. it will be observed from a comparison of the two definitions that the vehicles which have been taken out of the category of a 'motor vehicle ' are different in these two definitions. Before the amendment a motor vehicle though a motor vehicle within the meaning of the first part of the definition is nonetheless not so	 because of its specified user	 i.e. if it is used solely upon the premises of the owner. These vehicles under section 6 of the Taxation Act read with section 2(c) thereof would not attract liability to tax. But after the amendment though a motor vehicle may be adapted for use upon roads	 nonetheless in order to be taken out of the category of the definition it had to be further adapted	 namely	 it should be a vehicle of a special type adapted for use only in a factory or in any other enclosed premises. In other 145 words	 a motor vehicle of a special type adapted as stated in the post amendment definition would be such as would not be considered to be adapted for use upon roads. The position is the same with respect to the Motor Vehicles Taxation Acts of other States also. We have seen the Mysore Motor Vehicles Taxation Act	 1957	 which though does not define "motor vehicle" ' as such	 nonetheless under section 2(j) states that words and expressions used but not defined in the Act shall have the meanings assigned	 to them in the . It also says that the Mysore General Clauses Act	 1899 (Mysore Act III of 1899) shall apply for the interpretation of the Act	 as it applies for the interpretation of a Mysore Act. 'Section 3 is the taxing provision which provides that a tax at the rates specified in Part A of the Schedule shall be levied on all motor vehicles suitable for use on roads	 kept in the State of Mysore. In the Andhra Pradesh (Andhra Area) Motor Vehicles Taxation Act	 1931	 section 2(i) states that the expressions mentioned in clauses (a) to (f)	 of which clause (d) refers to 'motor vehicle '	 shall have the meanings assigned to them in the . It is also pertinent to mention that the Andhra Pradesh (Andhra Area) Motor Vehicles Taxation Act by section 2(v) defines a 'public road ' and by section 4 which is the taxing provision it is provided that the State Government may	 by notification in the Official Gazette	 from time to time direct that a tax shall be levied on every motor vehicle using any public road in the Andhra area of the State of Andhra Pradesh. The Madras Act uses the same language as that of the Andhra Pradesh (Andhra Area) Act. It appears that using any public road in the Presidency of Madras was first substituted for the words "kept or used in the Presidency of Madras" by section 3 (1) of the Madras Motor Vehicles Taxation (Amendment) Act	 1932 (Madras Act V of 1932). The Bombay Motor Vehicles Tax Act	 1958 follows the same pattern as the Mysore Act and though it does not define a 'motor vehicle '	 yet	 by section 2(10) it provides that other words and expressions used	 but not defined	 in the Act shall have the meanings respectively assigned to them in the . The Bengal Motor Vehicles Tax Act	 1932	 also is similar as that of the Bombay Act inasmuch as s.2(5) thereof states that words and expressions used	 but not defined	 in the Act shall have the same meaning as in the . In all these cases the common question would be whether the definition of a 'motor vehicle ' as it existed before the Amendment Act of 1956 is the same as in section 2(c) of the Taxation Act or does the definition in section 2(c) of the Taxation Act mean that the motor vehicle as defined in the Act from time to time is to be adopted for the purpose of section 2(c) of the Taxation Act. In so far as the larger question is L251 Sup. CI/75 146 concerned	 as	to Whether dumpers	 rockers and tractors are motor vehicles at all within the meaning of the first part of the definition of 'motor vehicle ' in section 2 (18) of the Act	 which is the same before and after the amendment	 it is contended that these vehicles are :not suitably adapted for use upon roads	 which according to the learned Advocates mean the public roads or roads	 to which the public has a right of access. The Motor Vehicles Taxation Acts are enacted in exercise of the powers conferred on the State Legislatures under entry 57 of List II of the Seventh Schedule to the Constitution	 while the is enacted by the Parliament in exercise of the 'concurrent legislative power in entry 35 of List III of the Seventh Schedule to the Constitution. Entry 57 of List II empowers legislation in respect of taxes on vehicles	 whether mechanically propelled or not	suitable for use on roads	 including tramcars subject to the provisions of entry 35 of List III. The power exercisable under entry 57 is the power to impost taxes which are in nature of regulatory and compensatory measures. The regulatory and compensatory nature of the tax is that the taxing power should be exercised to impose taxes on motor vehicles which use the roads in the State or are kept for use thereon either throughout the whole area or parts thereof and are sufficient to make and maintain such roads : See The Automobile Transport (Rajasthan) Ltd. vs The State of Rajasthan and others.(1) In this case	 the earlier decision in Atiabari Tea Company Ltd. vs The State of Assam and others (2) was considered. Since the taxing statute is a regulatory or compensatory statute	 it is contended that the provisions of sections 6B	 7	 9A of the Taxation Act relate only to the actual use of the public road. It is pointed out that section 6 of the Taxation Act does not place the burden of taxation on the registered owners of the motor vehicles	 but only on the persons who keep the motor vehicles for use which would mean use their on the public roads. If no such use of public roads is made or the vehicles are not such as can be used on the public roads	 then no tax could be levied under the Taxation Act. Reference in the Taxation Act to the registered owners is	 it is submitted	 meant only for the purpose of enabling refund of tax paid but not payable in terms of the Act	 or section 7 of the Taxation Act. Under Entry 35 of the Concurrent List	 the Parliament as well as the State Legislatures can legislate in respect of only mechanically propelled vehicles including the principles on which taxes on such vehicles are to be levied. It has no power to deal with vehicles which are not mechanically propelled though under the Taxation Act these non mechanically propelled vehicles which are suitable for use on roads can also be taxed even without their being registered under the Act. It will thus be seen that while entry 57 of List II is solely concerned with taxes on vehicles whether mechanically propelled or not	 entry 35 deals with also the principles on which taxes on such vehicles are to be levied. Taxes on vehicles cannot the liability to pay taxes at the rates at which the taxes are to be levied. On the other hand	 the expression 'principles of taxation ' denote rules of guidance in the matter of taxation. The ambit and amplitude of these two legislative entries in the respective Lists was dealt with in State of Assam & Others (1) [1963] 1 section C. R. 491. (2) ; 147 vs Labanya Probha Debi	(1) where Suba Rao CJ.	 speaking for the. Constitution Bench of this Court observed at p. 614 "The two entries deal with two different matters though allied ones one deals with taxes on vehicles and the other with the principles on which such taxes are to be levied. when two entries in the Constitution	 whether in the same List or different Lists	 deal with two subjects	 if possible	 an attempt shall be made to harmonize them rather than to bring them into conflict. Taxes on vehicles in their ordinary meaning connote the liability to pay taxes at the rates at which the taxes are to be levied. On the other hand	 the expression " principles of taxation" denotes rules of guidance in the matter of taxation. We	 therefore	 hold that the Amending Acts do not come into conflict with the existing law in respect of any principles of taxation	 but only deal with a subject matter which is exclusively within the legislative competence of the State Legislature. " It is contended that having regard to the nature of the vehicles question they are particularly suitable for the functions they are performing and unsuitable for the roads on which they would be only a source of damage	 inconvenience	 danger and uneconomical compared with the other vehicles usually utilised for transport of goods. Accordingly it is submitted that : (1) the present case should be determined with reference to the definition of 'motor vehicle ' read without the amendment in the Act	 as such vehicles operating solely within the appellants ' premises should not be liable to tax; (2) the vehicles not being suitable for public roads would not be either registered or taxed whether before or after 1956. Both for the purposes of registration and taxation the common question arises	 viz.	 whether the vehicles in question are adapted for use upon roads	 which	 it is submitted	 are public roads or roads to which public have a right of access. If they are not	 then they are not 'motor vehicles ' within the meaning of either the Act or the Taxation Act; (3) the concept 'adapted for use on roads ' must lie within the ambit of the expression used by the Constitution; otherwise it would be unconstitutional. It must	 therefore	 follow that the definition can only refer to vehicles which are reasonably suitable for the road in the sense that an average man could think that plying of the vehicles on the road would be one of the normal uses of the vehicles. That alone would be a test of suitability; and (4) for the interpretation of section 22 of the Act it would be permissible and even obligatory to examine the section not in isolation but in the light of the object and scheme of the Act and the regulatory provisions regarding the licensing of drivers	 issuing of permits	 provisions for compulsory registration and other regulatory provision are confined to the vehicles on the public roads. The provisions of section 22 are definitely to advance the objects of the Act and to effectuate the regulatory provisions. By the very language the principal purpose is to insist upon registration in respect of vehicles plying in public places. Further	 the (1) ; 148 expression must be interpreted to advance the object of the Act exactly as the other para of section 22 does. In this view the expression "purpose of carrying passengers or goods" cannot mean the personal use of the owner. A person himself cannot be the passenger and goods	 and as such it must not be interpreted disjunctively. It is a single expression "passenger or goods". It is conceivable that this alternative part of the section is only to ensure that in connection with the journey on a public road even if a motor vehicle goes into a place which will not be strictly a public place like hotel or inside a railway	 such as in a Railway Station	 or even inside the premises of a bus depot	 hospitals	 etc. provisions for compulsory registration should be applicable. The judgment of the High Court is assailed on the ground that while formulating the test to determine whether a vehicle is adapted for use on the roads it has evidently equated compatibility with suitability	 because at certain places it has laid down the test in terms of compatibility and at other places in terms of suitability. This is clearly illustrative by its decision regarding 'tractor '. A tractor without a tailor can neither carry passengers nor goods. In the instant case	 it is said that the tractor cannot ply in a public place	 nor does it ply in any other place for carrying passengers or goods. It could not evidently fall within section 22 of the Act. Though this is so	 the High Court says that because it can be adapted by attaching a tailor	 it comes within section 2(18)	 forgetting that what we are concerned with is a tractair without a tailor which is actually used to supply compressed air to certain plants or machines	 which clearly shows that the High Court did not have a correct concept of "adapted for use on road". Shri Soli Sorabji on behalf of the interveners has more or less adopted a similar line of argument and has referred us to the several dictionary meanings of the word 'adapted '. He has also referred to the English cases on this question and submitted that no vehicle cam be taxed unless it possesses the attribute of being "suitable for use on roads". The expression "adapted for use on roads" must be construed as suitable for use on roads in the light of entry 57; otherwise	 the legislation would be ultra vires the said entry	 and consequently such a construction should be avoided by courts. He further submitted that the Orissa High Court has misconstrued the judgment of the	 Supreme Court in State of Mysore vs Syed Ibrahim	(1) where the observations were made with reference to the definition of "a public service vehicle" as defined in section 2(25) of the Act	 under which user by itself was sufficient to bring the vehicle within its purview. He has referred us to sections 47(f)	 55(f)	 71(2)	 74	 75(1) and (3) and 77 of the Act in support of his proposition that having regard to the general object	 purpose and the policy underlying the Act the expression "roads" must mean public roads and not private roads. If so	 the dumpers	 rockers and tractors etc. which do not ply or are not suitable for plying on public roads cannot be either registered under the Act or taxed under the Taxation Act. Mr. Tarkunde for the State of Orissa submits that every motor vehicle registered under the Act is liable to pay tax under the Taxation Act and since dumpers	 rockers and tractors are by their nature (1) ; 149 adapted for use on the roads they are registerable	 and they have to be registered and are liable for payment of tax under the Taxation Act. There has been a good deal of argument on both sides on the meaning of the expression "adapted for use upon roads". We have been referred to certain English decisions which deal with the meaning of the word 'adapted ' in the English Road Traffic Act	 1960. While the definition of 'motor vehicle ' in the Act describes it as a mechanically propelled vehicle adapted for use upon roads	 the English Road Traffic Act describes it as a mechanically propelled vehicle "intended or adapted for use on roads". Even the earlier English Road Traffic Act	 1930	 had used the words "intended or adapted for use on roads"	 while making Part I applicable to motor vehicles. In Daley and others vs Hargreaves(1) the Queen 's Bench Division took the view that as there was no evidence sufficient to show that the dumpers were "intended or adapted for use on roads" within the meaning of section 36 of the Road and Rail Traffic Act.	 1933	 and section 1 of the Road Traffic Act	 1930	 and the case being indistinguishable in substance from the Scottish decision in MacDonald vs Carmichael(2) which the Court would follow for conformity	 it had not been established that dumpers were motor vehicles to which the regulations applied. In MacDonald 's case(2) it was held that the dumpers were solely used in connection with road construction and were not constructed to carry goods on an ordinary highway. They were so constructed as to be capable of	 and were in fact occasionally used for	 carrying road making material along short stretches of the public highway in the vicinity of the work of reconstruction. The ratio of that decision was applied to the Daley 's case	(1) where Salmon	 J. observed at p. 555 : "In my judgment	 the true effect of the Court of Justiciary 's decision was that the very limited use of the dumpers on the road in that case did not establish	 that they were "intended or adapted for use on the road"	 within the meaning of those words in the Road traffic Act	 1930	 section 1." Lord Parker	 C.J.	 though agreeing reserved his opinion by emphasising that it must not be taken as the result of this decision that dumpers of the type used in this case were not motor vehicles intended or adapted for use on the road. He indicated that he had agreed with Salmon	 J.	 merely because there was no proof in that case that the dumpers used were motor vehicles. While dealing with the English cases it must not be forgotten that the definition of "motor vehicle" in the Road Traffic Act imports the element of intention into the definition for ascertaining whether a vehicle is a motor vehicle. In Maddox V. Storer	(3) Lord Parker	 C.J.	 was construing the word "adapted" when used disjunctively with "constructed". He observed at p. 456 : "One can get illustration after illustration	 on looking at the Act itself	 where "adapted	 when used disjunctively with (1) (2) (3) 150 constructed" must mean a physical alteration	 and	 as it seems to me	 other cases where the word "adapted" alone is used and where it must be given the adjectival meaning of be ' fit and apt for the purpose." But where the word "adapted" alone has been used such as in subparagraph (2) of paragraph 1 of the First Schedule to the Road Traffic Act	 1960	 he was of the view that it was wholly inapt to mean "altered so as to make fit". He asked "How do you alter a motor car so as to make it fit to carry not more than seven passengers" ? It is clearly there standing on its own	 susceptible only of meaning "fit and apt for the purpose." In Burns vs Currell(1) also Lord Parker delivered the judgment. He referred to the decision in Daley	 MacDonald Maddox (supra) observed at p. 440 thus : "But to define exactly the meaning of the words "intended or adapted" is by no means easy. I think that the expression "intended"	 to take that word first	 does not mean "intended by the user of the vehicle either at the moment of the alleged offence or for the future". I do not think it means the intention of the manufacturer or the wholesaler or the retailer;" After referring to Salmon	 J. 's observations in Daley 's case (supra) and the suggestion that the word "intended" might be paraphrased as "suitable or apt" Lord. Parker pointed out that it may be merely a difference of wording	 but he preferred to make the test whether a reasonable person looking at the vehicle would say that one of its users would be a road user	 and then he dealt with the meaning of the word "adapted" and observed at p. 441 : "So far as the other word	 "adapted	 is concerned, as was pointed out in Maddox vs Storer (1963)1 Q.B. 451the word adapted" is used throughout the Road Traffic Act	 1960	 in a number of different contexts. Sometimes It is used as an alternative to "constructed" "constructed or adapted	 and it seems clear, and indeed it has been so held for a very long time, that adapted" there means altered. On the other hand	 as it was pointed out in Maddox vs Storer	 it is used in other contexts in this Act	 in particular when it stands alone	 as clearly meaning "apt" or "fit"	 in other words in an adjectival sense. Here in this context of intended or adapted my own view is	 though I think it is perhaps unnecessary to decide it in this case	 that "adapted	 used disjunctively with intended" and not with the word "constructed	 is used in its adjectival sense.  The decisions rendered on the definition of 'motor vehicle ' under the English Road Traffic Act are of little help	 because that definition (1) 151 has reference to the words "intended or adapted" while the element of intention has no relevance under the Act	 where the word "adapted" alone is used. It has been urged before us that since the learned thief Justice Lord Parker had referred to the meaning of the words "intended" and "adapted" separately in the context of the English Road Traffic Act	 we should take assistance from his observations. It appears to us that where two words of different import are used which in the context	 of the scheme of the Act and its purpose play an important part	 to ask us to take the meaning given of one of the words and import it as the meaning for the purposes of the Act even when the same word is used	 is perhaps to place us in a similar predicament as that of the gentleman who when asked to expound on Chinese metaphysics	 not knowing how to begin looked up the article on China in the Encyclopedia Britannica and also on metaphysics and combined the two into Chinese metaphysics. As usual references have been made to the Dictionaries but quite often it is not possible to hold a dictionary in one hand and the statute to be interpreted in the other for ascertaining the import and intent of the word or expression used by the Legislature. The shade of meaning of a word	 its different connotations and collocations which one finds in a dictionary does not relieve us of the responsibility of having to make the ultimate choice of selecting the right meaning We choose that meaning which is most apt in the context	 colour and diction in which the word is used. The use of a dictionary ad lib without an analysis of the entire Act	 its purpose and its intent	 for ascertaining the meaning in which the Legislature could have used the word or expression may not lead us to the right conclusion. With this caution before us for avoiding any of the aforesaid methods which might lead to a possible incongruity	 we will examine the different facets to which our attention has been drawn. The meaning of the word "adapted" in section 2(18) of the Act is itself indicated in entry 57 of List II of the Seventh Schedule to the Constitution	 which confers a power on the State to tax vehicles whether propelled mechanically or not and uses the word "suitable" in relation to its use on the roads. The words "adapted for use" must therefore be construed as "suitable for use". At any rate	 words "adapted for use" cannot be larger in their import by including vehicles 'Which are not " suitable for use ' on roads. In this sense	 the words "is adapted" for use have the same connotation as "is suitable " or" is fit" for use on the roads. The question would then arise	 are dumpers	 rockers and tractairs suitable or fit for use on roads ? It is not denied	 that these vehicles are on pneumatic wheels and can be moved about from place to place with mechanical power. 'The word "vehicle" itself connotes that it is a contrivance which moves. A vehicle which merely moves from one place to another need not necessarily be a motor vehicle within the of a.2(18) of the Act. It may move on iron flats made into a chain such as a caterpillar vehicle or a military tank. Both move from one place to another but are not suitable for use on roads. It is not that they cannot move on the roads but they are not adapted	 made fit or suitable for we on roads. They would	 if used	 dig and 152 damage the roads. It is contended that the dumpers or rockers are very heavy and though they can move on roads they would damage the roads and	 therefore	 they are not suitable for use on roads. To substantiate this proposition the appellants have produced before us certain notifications issued by the State of Orissa under which vehicles beyond a certain laden. weight are prohibited from plying on the roads. It was rightly pointed out by the learned Advocate for the State of Orissa that there are only some of the roads on which vehicles heavier than what is indicated in the notification cannot be permitted. But that is not to say that all vehicles which exceed a particular weight are not adapted for use upon roads and are	 therefore	 not motor vehicles. A dumper in the Mysore case according to the manufacturer 's own specifications is suitable for roads and is described thus : " The dumper will carry: bulk goods	 building materials	 mining products	 agricultural and forestry products	 earth	 stones	 bricks	 concrete	 mortar	 etc. The structure is of simple design and easy to handle. Tripping is performed by releasing the locking device retaining the tipping body. The dumper requires no more than a few seconds for the emptying of its tipping body and gives no trouble to the driver when being operated on uphill or downhill roads	 With its load unbalanced	 or when the load refuses to slide out easily. Quickness and ease characterise the operation of the dumper and the clumsy manoeuvring can be dispensed with. In narrow lanes or rough roads where turning would be impossible or undesirable	 the seat is turned and will face driving direction. " It is also averred in the plaint in the suit filed by the appellant Bolani Ores Ltd. that Euclid Dumpers are used for transporting ore from the mining faces to the crushing and screening plant or from head mine stockpile to near railway siding. Rockers also seem to be similar to dumpers. But in this case rockers are heavier than dumpers. In so far as the tractairs are concerned	 attachments are fitted for the purpose of supplying compressed air to Jack Hammer Drills which are used to drill holes in the ore body so that explosive charges may be inserted in them to break the ore into manageable sizes. In respect of all these three types of vehicles it cannot be said that they are not adapted for use upon roads. That they are not so used or are confined for use to only places other than roads or public places is a different matter	 because whether they have to be registered under the Act or are liable for payment of tax under the Taxation Act will depend upon the provisions of the respective Acts. In so far as the Act is concerned	 we must bear in mind that it is essentially an Act to regulate transport 	 The statement of objects and 153 reasons given for the 1939 Act	 in so far as it is relevant for our purpose states thus "It has been recognised now for some years past that the Indian Motor Vehicles Act	 1914 which was framed to suit conditions at an early stage of development of motor transport	 is no longer adequate to deal with conditions brought about by the rapid growth of motor transport in the past two decades. In the interest alike of the safety and convenience of the public and of the development of a so called system of transport	 much closer control is required than the present Act permits	 and it is necessary to take powers to regulate transport. " A perusal of the provisions of the Act	 in the light of the objects and reasons	 would justify the conclusion that it is not necessary for every vehicle registered under the Act to be also liable for payment of tax under the Taxation Act. It may be that a vehicle is registerable under the Act but not liable for tax under the Taxation Act. For instance section 22 of the Act provides : "No person shall drive any motor vehicle and no owner of a motor vehicle shall cause or permit the vehicle to be driven in any public place or in any other place for the purpose of carrying passengers or goods unless the vehicle is registered. " Similarly under section 3 of the Act "No person shall drive a motor vehicle in any public place unless he holds an effective driving licence issued to himself authorizing him to drive the vehicle	 and no person shall be drive a motor vehicle as a paid employee or shall so drive a transport vehicle unless his driving licence specifically entitles him so to do." A 'motor vehicle ' under section 2(18) has been defined as any mechanically propelled vehicle adapted for use upon roads. Having regard to the context of the definition of "public place" in section 2(24) of the Act	 the regulatory character of the Act	 and the use of the word 'road ' used in a public Act	 road would mean a "public road" which word as already noticed has been used will the Andhra Pradesh (Andhra Area) Motor Vehicles Taxation Act. The word "public place" has been defined in section 2(24) as meaning "a road street	 way or other place "whether a thoroughfare or not	 to which the public have a right of access". If the public have no right of access to any place which is not a road	 street	 way or thoroughfare it will not be a public place. A motor vehicle which is not adapted for use upon roads to which the public have no right of access is not a motor vehicle within the meaning of section 2(18) of the Act. But where a vehicle is adapted for use on a road which is neither more nor less than that it is made suitable or fit for use upon road	 i.e. public roads	 it is a motor vehicle	 and if such a motor vehicle is a goods vehicle under section 2(8) which means a vehicle which is not only suitable or fit for use upon roads but is "constructed or adapted for use for the carriage of goods" or where it is not so constructed or adapted when used for the carriage of goods solely or in addition to passengers	 car is a public service vehicle within the meaning of section 2(25) of the Act	 namely " an motor vehicle used or adapted to be used for the 154 carriage of passengers for hire or reward it has to be registered under section 22 and can only be driven by a person who holds a licence under section 3 of the Act. Where a vehicle is adapted for use upon roads and though it is not driven on the Public roads or in a public place even then if it carries goods car passengers which may not be for hire or reward or the passengers may be friends or relatives of the owner or the goods may belong to the owner and plying in a place to which the public has	 as a matter of right	 no access	 it nonetheless cannot be driven without its being registered or without the driver holding a licence to drive such a vehicle. In so far as the Act is concerned	 having regard to the fact that the dumpers and rockers are motor vehicles which are not taken out of that category	 as was the case before the amendment	 they have to be registered after the amendment and can only be driven by persons holding a valid licence. The tractair though it may be a motor vehicle within the definition of that term is neither a goods vehicle nor a vehicle which carries passengers nor is it being driven in a place to which public have as a right access. As it does not perform any of the aforesaid functions or uses it is not a vehicle which has to be registered nor has it to be driven only by a person who holds a licence. The question then remains as to whether these vehicles though registrable under the Act are motor vehicles for the purpose of the Taxation Act. It has already been pointed out that before the amendment vehicles used solely upon the premises of the owner	 though they may be mechanically propelled vehicles adapted for use upon roads were excluded from the definition of 'motor vehicle '. If this definition which excludes them is the one which is incorporated by reference under section 2 (c) of the Taxation Act	 then no tax is leviable on these vehicles under the Taxation Act. Shri Tarkunde for the State of Orissa contends that the definition of 'motor vehicle ' in section 2(c) of the Taxation Act is not a definition by incorporation but only a definition by reference	 and as such the meaning of 'motor vehicle for the purpose of section 2(c) of the Taxation Act would be the same as defined from time to time under section 2(18) of the Act. In ascertaining the intention of the Legislature in adopting the method of merely referring to the definition of 'motor vehicle ' under the Act for the purpose of the Taxation Act	 we have to keep in mind its purpose and intendment as also that of the Motor Vehicles Act. We have already stated what these purposes are and having regard to them the registration of a motor vehicle does not automatically make it liable for taxation under the Taxation Act. The Taxation Act is a regulatory measure imposing	 compensatory taxes for the purpose of raising revenue to meet the expenditure for making roads	 maintaining them and for facilitating the movement and regulation of traffic. The validity of the taxing power under entry 57 List II of the Seventh Schedule read with article 301 of the Constitution depends upon the regulatory and compensatory nature of the taxes. It is not the purpose of the Taxation Act to levy taxes on vehicles which do not use the roads or in any way form part of the flow of traffic on the roads which is required to be regulated. The regulations under the Motor Vehicles Act for registration and prohibition of certain categories of vehicles being driven by persons 155 who have no driving licence	 even though those vehicles are not plying can the roads	 are designed to ensure the safety of passengers and goods etc. and for that purpose it is enacted to keep control and check on the vehicles. Legislative power under Entry 35 of List III (Con V current List) does not bar such a provision. But Entry 57 of List II is subject to the limitations referred to above	 namely	 that the power of taxation thereunder cannot exceed the compensatory nature which must have some nexus with the vehicles using the roads viz. public roads. If the vehicles do not use the roads	 notwithstanding that they are registered under the Act	 they cannot be taxed. This very concept is embodied in the provisions of section 7 of the Taxation Act as also the relevant sections in the Taxation Acts of other States	 namely	 that where a motor vehicle is not using the roads and it is declared that it will not use the roads for any quarter or quarters of a year or for any particular year or years	 no tax is leviable thereon and if any tax has been paid for any quarter during which it is not proposed to use the motor vehicle on the road	 the tax for that quarter is refundable. If this be the purpose and object of the Taxation Act	 when the motor vehicle is defined under section 2(c) of the Taxation Act as having the same meaning as in the Motor Vehicle Act	 1939	 then the inten tion of the Legislature could not have been anything but to incorporate only the definition in the Motor Vehicles Act as then existing	 namely	 in 1943. as if that definition was bodily written into section 2(c) of the Taxation Act. If the subsequent Orissa Motor Vehicles Taxation (Amendment) Act	 1943	 incorporating the definition of motor vehicle ' referred to the definition of 'motor vehicle	 under the Act as then existing	 the effect of this legislative method would	 in our view	 amount to an incorporation by reference of the provisions of section 2(18) of the Act in section 2(c) of the Taxation Act. Any subsequent amendment in the Act or a total repeal of the Act under a fresh legislation on that topic would not affect the definition of 'motor vehicle ' in section 2(c) of the Taxation Act. This is a well accepted interpretation both in this country as well as in England which has to a large extent influenced our law. This view is further reinforced by the use of the word has in the expression "has the same meaning as in the " in section 2(c) of the Taxation Act	 which would perhaps further justify the assumption that the Legislature had intended to incorporate the definition under the Art as it then existed and not as it may exist from time to time. This method of drafting which adopts incorporation by reference to another Act whatever may have been its historical justification in England	 in this country does not exhibit an activities draftsmanship which would have adopted the method of providing its own definition. Where two Acts are complimentary or interconnected	 legislation by reference may be an easier method because a definition given in the one Act may be made to do as the definition in the other Act both of which being enacted by the same Legislature. At any rate	 Lord Esher	 M.R.	 dialing with legislation by incorporation	 in In re. Wood 's Estate state(1) said at p. 615: If a subsequent Act brings into itself by reference some of he clauses of a former Act	 the legal effect of that	 as has (1) 156 often been held	 is to write those sections into the new Act just as if they had been actually written in it with the pen	 or printed in it	 and	 the moment you have those clauses in the later Act	 you have no occasion to refer to the former Act at all. " The observations in Clarke vs Bradlaugh(1) are also to the same effect. Brett	 L.J.	 in that case had said at p. 69 : ". . there is a rule of construction that	 where a statute is incorporated by reference into a second statute	 the repeal of the first statute by a third statute does not affect the second." In Secretary of State for India in Council vs Hindusthan Co operative Insurance Society Ltd.(2) the Privy Council was considering a case where the incorporation effected in the statute	 viz.	 the Calcutta Improvement Trust Act	 1911 referred to by their Lordships as the "Local Act" was in express terms and in the form illustrated by 54 and 55 Vict.	 Ch. 19. The "Local Act in dealing with the acquisition of land for the purposes designated by it	 made provision for the acquisition under the Land Acquisition Act	 and the provisions of the Land Acquisition Act were subjected to numerous modifications which were.	 set out in the Schedule	 so that in effect the "Local Act" was held to be the enactment of a Special Law for the acquisition of land for the special purpose. It was in the context of these and several other provisions which pointed to the absorption of certain of the provisions of the Land Acquisition Act into the "Local Act" with vital modifications that Privy Council observed at p. 266 "But their Lordships think that there are other and perhaps more cogent objections to this contention of the Secretary of State	 and their Lordships are not prepared to hold that the sub section in question	 which was not enacted till 1921	 can be regarded as incorporated in the Local Act of 1911. It was not part of the Land Acquisition Act when the Local Act was passed	 nor in adopting the provisions of the Land Acquisition Act is there anything to suggest that the Bengal Legislature intended to bind themselves to any future additions which might be made to that Act. It is at least conceivable that new provisions might have been added to the Land Acquisition Act which would be wholly unsuitable to the Local code. Nor again	 does Act XIX of 1921 contain any provision that the amendments enacted by it are to be treated as in any way retrospective	 or are to be regarded as affecting any other enactment than the Land Acquisition Act itself. Their Lordships regard the local Act as doing nothing more than incorporating certain provisions from an existing Act	 and for convenience of drafting doing so by reference to that Act	 instead of setting out for itself at length the provisions which it was desired to adopt." (1) [1881] 8 Q. D. D. 63. (2) L. R. 58 I. A. 259. 157 It was further observed at p. 267 : "In this country it is accepted that where a statute is incorporated by reference into a second statute	 the repeal of the first statute does not affect the second : see the cases collected in Craies on Statute Law	 3rd edn. pp. 349	 350. This doctrine finds expression in a common form section which regularly appears in the amending and repealing Acts which are passed from time to time in India. x x x x x The independent existence of the two Acts is therefore recognized; despite the death of the parent Act	 its offspring survives in the incorporating Act. Though no such saving clause appears in the General Clauses Act	 their Lordships think that the principles involved is as applicable in India as it is in this country. It seems to be not less logical to hold that where certain provisions from an existing Act have been incorporated into a subsequent Act	 no addition to the former Act	 which is not expressly made applicable to the subsequent Art	 can be deemed to be incorporated in it	 at all events if it is possible for the subsequent Act to function effectually without the addition." This Court in The Collector of Customs	 Madras vs Nathelle Sampethu Chetty and Another(1) considered the Privy Council decision in the Hindusthan Co operative Insurance Society Ltd. (2) and distinguished that case and held the principle inapplicable to the facts of that case. In State of Bihar vs section K. Roy(2) this Court was considering the definition of "employer" in section 2(e) of the Coal Mines Provident Fund and Bonus Schemes Act	 1948	 Where that expression was defined to. mean "the owner of a coal mine as defined in clause (g) of section 3 of the Indian Mines Act	 1923". The Indian Mines Act	 1923	 had been repealed and substituted by the (Act 35 of 1952). In the latter Act the word "owner" had been defined in cl. (1) of section 2. The question was whether by virtue of section 8 of the General Clauses Act	 the definition of the word "employer" in cl. (e) of section 2 of the Coal Mines Provident Fund and Bonus Schemes Act should be construed with reference to the definition of the word "owner" in cl. (1) of section 2 of Act 35 of 1952	 which repealed the earlier Act and reenacted it. It may be mentioned that according to section 2(1) of Act 35 of 1952 the word "owner"	 when used in relation to a mine	 means " any person who is the immediate proprietor or lessee or occupier of the mine or of any part thereof and in the case of a mine the business whereof is being carried on by a liquidator or receiver	 such liquidators receiver. . . The expression "coal mine" is separately defined in cl. (b) of section 2 of the Coal Mines Provident Fund and Bonn&	 (1) ; 	 at pp. 830 833. (2) L.R. 58 I.A. 259. (3) [1966] Supp. S.C.R. 259. 158 Schemes Act	 1948. Ramaswami	 J.	 speaking for the Court observed at p. 261 : "As a matter of construction it must be held that all works	 machinery	 tramways and sidings	 whether above or below ground	 in nor adjacent to a coal mine will come within the scope and ambit of the definition only when they belong to the coal mine. In other words	 the word "or" occurring before the expression "belonging to a coal mine" in the main definition has to be read to mean "and". " This case	 as well as the decision in New Central Jute Mills Co. Ltd. V. The Assistant Collector of Central Excise	 Allahabad & others	(1) are distinguishable on the facts and legislation which this Court was considering. In the New Central Jute Mills Co. Ltds.(1) case	 the Privy Council decision in the Hindusthan Co operative Insurance Society Ltd. 's case (supra) was referred to and distinguished. It is	 however	 contended by the learned Solicitor General that both in Nathella Sampathu Chetty 's case (supra) as well as the New Central Jute Mills Co. Ltd. 's case(1) this Court was considering the effects of the two Acts which were made by Parliament by central legislation and it is	 therefore	 not strictly a case of incorporation because the Central Legislature is deemed to have	 while making the latter enactment	 kept in view the provisions of the former Act. In our view this may not be conclusive. in Ram Sarup vs Munshi and Others(2) a judgment of the Bench of five Judges of this Court held that the repeal of the Punjab Alienation of Land Act	 1900	 had no effect on the continued operation of the Punjab Preemption Act	 1913	 and that the expression "agricultural land ' 'in the later Act had to be read as if the definition of the Alienation of Land Act had been bodily transposed into it. After referring to the observations of Brett	 L.J.	 in Clarke 's case (supra)	 Rajagopala Ayyangar	 J.	 speaking for the court observed at pp. 868869 : "Where the provisions of an Act are incorporated by reference in a later Act the repeal of the earlier Act has	 in general	 no effect upon the construction or effect of the Act in which its provisions have been incorporated. x x x x x x In the circumstances	 therefore	 the repeal of the Punjab Alienation of Land Act of 1900 has no effect on the continued operation of the Preemption Act and the expression ' agricultural land ' in the later Act has to be read as if the definition in the Alienation of Land Act had been bodily transposed into it. " The above decision of this Court is more in point and supports our conclusion. In our view	 the intention of Parliament for modifying the has no relevance in determining the intention of the Orissa Legislature in enacting the Taxation Act. Apart from (1) (2) ; 159 this aspect the power; of	 taxation as we	 have said earlier	 is not in the Concurrent List III but in List II and construed as a taxation measure we cannot extend the	 ambit	 of it by mere implication. As we said it is possible for both the Acts to co exist even after the definition of 'motor vehicle ' in the Act has been amended. It is	 therefore	 clear that the definition of 'motor vehicle as existing Prior to 1956 Amendment would alone be applicable as being incorporated in the Taxation Act. Mr. Tarkunde has referred to section 6 of the in support of his contention that after the amendment	the amended definition would apply to the Taxation Act. But we do not think that there is any justification for this	submission. Section 6 of the 	 specifically refers to that Act	 or any Central Act or Regulation made after the commencement of the and states that if these Acts repeal any enactment	 hitherto made or hereafter to be made	 then	 unless a different intention appears	 the repeal shall not affect the matters specified in clauses (a) to (e) of that section. Since the Taxation Act is a State Act neither section 6 nor section 6A of the has any relevance. That Act has to be interpreted in the light of the Orissa and since there is no question of any amendment or any repeal of any of the Orissa Acts affecting the Taxation Act	 section 7 of the Orissa has also no relevance. If so the question is whether these vehicles were used solely upon the premises of the owner. On this aspect	 there can be no doubt	 because there is evidence to show that dumpers	 rockers and tractaires (tractors with air compressed attachment) are exclusively used on the premises of the owners. In Civil Appeal No. 1816 of 1968 P. W. 1 Assistant Superintendent of Mines	 Bolani Ores Ltd.	 stated that there is no public road within their leasehold premises. No member of public is allowed to enter into leasehold premises without due permission obtained before hand. They have check gates on the approach road to their leasehold. All the machines are within leasehold and never outside it. In cross examination	 no doubt he admitted that the leasehold has no fence. He	 however	 stated that there is an official approach road to the plant. He also stated in cross examination that there is a gate book	 gate register and a security guard. From this evidence it is clear that though there is no fence	 there are check gates	 and the public are not allowed to enter into the leasehold without prior permission and the machines are used within the leasehold premises. The mere fact that there is no fence does not mean that the leasehold premises are not enclosed premises. It is obvious that no one can get into the leasehold premises without having to go through the gate for which gate book	 gate register and security guard are provided. In Civil Appeal No. 1817 of 1968 Orissa Mineral Development Company 's case	 P. W. 1 stated in his evidence that the dumpers in the schedule were to carry ores from the place of excavation in the railway wagon within the mining area. The members of the public have no right to enter into it. There are check gates and guards. 160 P. W. 2 stated in his evidence that the suit vehicles were used at the place of mining operations. The members of the public have no access to the mining area. There were ten to twelve guards around the mining area and there were also guards at the gates of the approaching road. The guards were to prevent the unauthorised persons to enter into the mining area and there was a duty chart of those guards. No doubt	 P. W. 4 stated in his evidence that the area within which the machines were used was neither fenced nor walled around. Similarly in Civil Appeal No. 336 of 1970 in the case of Dalmia Cement Bharat Ltd it has been stated in the reply affidavit in paragraph 4 that a "trench 4 'X4 'x2 ' is dug alround the mining area so as to prevent free ingress and egress to the mining area. Certain pit areas are fenced with barbed wire. In fact to avoid accidents	 particular area where dumpers are being used have necessarily to be fenced. This is required under the Mining Act and Rules framed thereunder. " In reply to paragraph 4 it has been stated by the respondent that the allegations of the deponent in paragraph 4 of his affidavit except the allegation that the mining area is a well defined and enclosed area are substantially correct. From the very nature of the area operated by these three companies it is obvious that the machines which are the subject matter of these appeals must be working in their respective mining areas. The mere fact that there is no fence or the barbed wire around	 the leasehold premises is not conclusive. There is evidence to show that the public arc not allowed to go inside without prior permission	 there are gates and a check on ingress and egress is kept by guards who also ensure that no unauthorised persons have access to the mining area	 all of which indicate that the respective mining areas are enclosed premises within the meaning of the exceptions under section 2(c) of the Taxation Act. In the result Civil Appeal 336/70 is dismissed with cost and other appeal 	 are partly allowed and it is held that dumpers and rockers though registrable under the Act are not taxable under the Taxation Act as long as they are working solely within the premises of the respective owners. So far as the tractairs are concerned they are neither registerable under the Act nor taxable under the Taxation Act. The appellants will get proportionate costs. As we have held that these machines are not taxable the question about the constitutional validity of the Taxation Act challenged by Writ Petition No. 372 of 1974 filed by Bolani Ores Ltd. would become academic and need not be considered. The writ petition is accordingly dismissed but without costs. P.B.R. C.A.336/70 and W.P. 372/74 dismissed C. A. 1816 1817/68 partly allowed.

The appellants who owned Dumpers	 Rockers and Tractors claimed that these machines were not liable for registration under section 22 of the Indian and as such were not taxable under section 6 of the Bihar and Orissa Motor Vehicles Taxation Act	 1930. The trial court held that the machinery were motor vehicles within the meaning of section 2(18) of the and were therefore liable for registration under that Act and so to payment of tax under the Taxation Act. The High Court held that unless it was shown that the vehicles were of a special type adapted for use only in factories or enclosed premises and incapable of running on any other type of roads or public roads the vehicles were motor vehicles and that the three types not being motor vehicles were not liable for registration under section 22 of the Act nor were they subject to payment of tax under the Taxation Act. Section 2(c) of ' the Taxation Act adopted the definition of motor vehicle contained in the Motor Vehicles Act	 1914. The Motor Vehicles Act	 1914 was repealed and replaced by the . The definition of motor vehicle in section 2(18) of the having been redefined the Taxation Act	 by the Orissa Amendment Act 2 of 1940 adopted that definition for the purpose of taxation. The Orissa Amendment Act	 1943 reenacted provisions of sections 2 to 8 of the Taxation Act as the Amendment Act 2 of 1940 was due to expire. Section 2(18) of the was amended by Act 100 of 1956. But there was no corresponding amendment in the definition of section 2(c) of the Taxation Act. It was contended in this Court that under the definition of motor vehicle as it existed prior to amendment or subsequent thereto dumpers	 rockers and tractors were not motor vehicles because they were not adapted to use on the road and (2) the definition of motor vehicle in section 2(c) of the Taxation Act is not a definition by incorporation but only a definition by reference and as such the meaning of motor vehicle for the purpose of section 2(c) of the Taxation Act would be the same as defined from time to time under sections 8(2) to 18 of the . HELD : Dumpers and rockers though registrable under the are not taxable under the Taxation Act as long as they are working solely within the premises of the respective owners. So far as the tractairs are concerned they are neither registrable under the nor taxable under the Taxation Act. [160 F] A motor vehicle which is not "adapted for use" upon roads to which public have no right of access is not a motor vehicle within the meaning of section 2(18) of the Act. The words "is adapted for use" have the same connotation as "is suitable" or "is fit" for use on the roads. The meaning of the word adopted" in section 2(18) of the Act is itself indicated in entry 57 of List If of the 7th Schedule to the Constitution which confers powers on the State to tax vehicles whether propelled mechanically or not and uses the words "suitable" in relation to its use on the roads. The words "adapted for use" must. therefore	 be constructed as "suitable for use". The words "adapted for use" 139 cannot be larger in their import by including vehicles which are not "suitable for use" on roads. A perusal of the provisions of the Act would justify the conclusion that it is not necessary for other vehicles registered under the Act to	 be also liable for payment of tax under the Taxation Act. [153 G A; 151 F G] Daley and others vs Hargreaves 	 MacDonald vs Carmichael 	 Maddox vs Storer and Burns vs Currell 	 referred to. (2) The power of taxation under Entry 57 List II cannot exceed the compensatory nature which must have some nexus with the vehicles using the public roads. If the vehicles do not use roads notwithstanding that they are registered under the Act they cannot be taxed. If this be the Purpose and object of the Taxation Act	 when the motor vehicle is defined under section 2(c) of the Taxation Act as having the same meaning as in the then the intention of the legislature could not have been anything but to incorporate only the definition in the as it existed in 1943	 as if that definition was bodily written into section 2(c) of the Taxation Act. If the subsequent Orissa Motor Vehicle Taxation (Amendment) Act 1943 incorpo rating the definition of "motor vehicle" referred to the definition of "motor vehicle" under the Act as then existing the effect of this regulative method would amount to an incorporation by reference to the provisions of section 2(18) of the Act in section 2(c) of the Taxation Act. Any subsequent amendment in the Act or a total repeal of the Act under a fresh legislation on that topic would 'not affect the definition of "motor vehicle" in section 2(c) of the Taxation Act. [155 B; D E] The use of the word 'has ' in the expression "has the same meaning as in the Motor Vehicle Act	 1939" in section 2(c) of the Act would justify the assumption that the legislature had intended to incorporate the definition under the Act as it then existed and not as it may exist from time to time	 [155 F] In re. Woa 's Estate (1886)31 Ch. D.607	 Clarke vs Bradlaugh (1888)8 Q.B.D. 63	 Secretary of State for India in Council vs Hindusthan Co operative Insurances Society Ltd. L.R. 58 I.A. 259	 State of Bihar vs section K. Ray [1966] Supp. S.C.R. 259 and Ram Sarup vs Munshi and Others ; 	 referred to. The definition of motor vehicle as existing prior to the 1956 amendment of the would alone be applicable as being incorporated in the Taxation Act. The intention of Parliament for modifying the has no relevance in determining the intention of the Orissa Legislature in enacting the Taxation Act. The power of taxation is not in the concurrent List but in List It and construed as a taxation measure the ambit of it cannot be extended by mere implication. It is possible for both the Acts to Co exist even after the definition of "motor vehicle" in the Act has been amended. [159 B; 158 H] In the instant case there is evidence to show that the dumpers	 rockers and tractairs are exclusively used on the premises of the owners. [159 E] The machines which are the subject matter of these appeals must be working in their respective mining areas. The mere fact that them is no fence or barbed wire around the leasehold premises is not conclusive. There is evidence to show that the public are not allowed to go inside without prior permission	 there are gates and a check on ingress and egress is kept by guards who also ensure that no unauthorised persons have access to the mining area.
