Summarize the following court judgment. ivil Appeal No. 4879 of 1989. From the Judgment and Order dated 12.11.1986 of the Andhra Pradesh High Court in W.P. No. 16535 of 1986 P. Rama Reddy and A.V.V. Nair for the Appellants. C. Sitaramaiah	 Jagan Rao	 D.R.K. Reddy and T.V.S.N. Chari for the Respondents. The Judgment of the Court was delivered by SABYASACHI MUKHARJI	 J. Leave granted. This is an appeal from the judgment and order of the High Court of Andhra Pradesh dated 12th November	 1986. The appellants challenged the validity of an amendment to the Schedule to the Andhra Pradesh General Sales Tax Act	 1957 (hereinafter called 'the Act '). The appellants are dealers in tamarind in Parvathipuram in Srikakulam district	 a border district in Andhra Pradesh. They had purchased tama rind from the State of Orissa paying tax there and incurring expenditure in bringing the said goods to Andhra Pradesh for the purpose of sale. Under the Act	 tamarind was item 14 of Second Schedule and was subjected to sales tax at the point of first purchase in the State irrespective of whether it was purchased within the State or outside the State. The subject matter of challenge in this application under article 226 of the Constitution before the Andhra Pradesh High Court	 was the validity of an amendment to the Schedule to the Act modifying the point of taxability of tamarind in question. Prior to the amendment tamarind was taxable as mentioned hereinbefore at the first purchase point	 being item No. 14 in Schedule II to the Act. The entry therein read as follows: "Description of Point of levy Rate of tax the goods 14. Tamarind (2014) At the point of 4 paise in first purchase the rupee. in the State. " 425 By virtue of the amendment	 the said entry was amended. Tamarind which is purchased within the State	 was retained in IInd Schedule while tamarind purchased outside the State was transferred to 1st Schedule. After the amendment	 item No. 14 in Schedule II and item 170 in Schedule I stood as follows: "SECOND SCHEDULE section No. Description of goods Point of levy Rate of tax 14. Tamarind when put At the point of 4 paise in chased within the first purchase the rupee. State. in the State. FIRST SCHEDULE section No. Description of Goods Point of levy Rate of tax 170 Tamarind when At the point 4 paise in obtained from out of first sale the rupee. side the State. in the State. " It appears that the result of the said amendment was that tamarind purchased outside the State	 was taxable at the point of first sale in the State. It was contended before the High Court that the said amendment brought about a discrimination between tamarind purchased within the State i.e. one produced within the State	 and the tamarind pur chased outside the State i.e. produced in other States; and that the incidence of tax was more on the tamarind purchased outside the State. It was contended that it violated clause (a) of article 304 as also article 14 of the Constitution. Clause (a) of article 304 states that notwithstanding anything contained in article 301 or article 303	 the legislature of State may by law impose on goods imported from other States or the Union Territories any tax to which similar goods manufactured or produced in the State are subject	 so	 however	 as not to discriminate between goods so imported and goods so manufactured or produced. The question is whether as a result of the said amendment	 there has been any infraction of clause (a) of article 304 of the Constitu tion. We are unable to 426 accept the contention that there was any such discrimina tion. The High Court in the judgment under appeal has so held. We are of the opinion that the High Court was right. Both the tamarind purchased within	 and outside	 the State is taxed uniformly. On behalf of the appellants	 reliance was placed on Firm A.T.B. Mehtao Majid and Co. vs The State of Madras	 14 STC 355	 wherein on an analysis of the relevant provisions it was held that the provisions of rule 16(2) of the Madras General Sales Tax [Turnover and Assessment] Rules	 1939 (substituted in the place of the old rule w.e.f. 1st April	 1955) discriminate between hides and skins imported from outside the State and those manufactured or produced inside the State and as such contravened the provisions of article 304(a) of the Constitution	 and therefore were invalid. It was reiterated by this Court that taxing laws can be re strictions on trade	 commerce and intercourse	 if they hamper the flow of trade and if these are not compensatory taxes or regulatory measures. It was further held that sales tax on hides and skins imposed under the Madras General Sales Tax Act	 1939 and the rules framed thereunder could not be said to be a measure regulating any trade or compen satory tax levied for the use of trading facilities. The similarity contemplated by article 304(a) is in the nature of the quality and kind of the goods and not with respect to whether they were already the subject of tax or not. There this Court was dealing with rule 16 of the relevant Madras rules. Sub rule (a) of rule 16 provides that in case of untanned (raw) hides and/or skins	 the tax u/s 3(1) of the Act was to be levied from the dealer who is the last pur chaser in the State. Sub rule (2) which was in two parts	 dealt with tanned hides and skins. Clause (i) of sub rule (2) provided that in case of hides and skins tanned outside the State	 tax shall be levied upon the dealer who in the State is the first dealer. Clause (ii) provided that in case of tanned hides and skins which have been tanned within the State	 the tax u/s 3(1) shall be levied upon a person who is the first dealer in such hides or skins. The proviso	 howev er	 declared that if the dealer proved that he had already been taxed under sub rule (1) on the untanned hides and skins	 he shall not be subjected to tax under sub rule (2). It was held by this Court that this rule inevitably brought about a discrimination in the quantum of tax because while the tanned hides and skins which were imported from outside the State and were sold within the State	 were taxed at a higher rate	 the hides and skins tanned within the State and sold within the State	 are taxed at a lower rate by virtue of the proviso. It was	 indeed	 found that there was a substantial variation between the prices of tanned and untanned goods. This Court pointed out that by virtue of the proviso	 the tax on 427 the latter category was	 in fact	 on the purchase price of the untanned hides and skins though ostensibly the rate of tax under sub rule (2) was the same Hence	 the mischief of discrimination was brought about by the proviso which said that if hides and skins are taxed within the State at raw (untanned) stage	 they shall not be taxed again at the tanned stage. But in view of the facts involved in the instant case	 we are unable to accept that the principles of the said decision have any scope of application to the facts of instant case. In the instant case the tamarind purchased within the State and outside the State	 are taxed at the same rate. But the point of taxability has necessarily to be different in both the cases. In case of tamarind purchased within the State i.e. produced within the State	 the tax is levied at the point of first purchase	 and in case of im ported tamarind i.e. purchased outside the State	 the tax is levied at the point of first sale in the State. It was contended by Mr. P. Rama Reddy	 learned advocate for the appellants	 that tax in case of imported tamarind would be more because its price will include freight charge and other State taxes. Hence	 it was submitted that the sales tax will also be more. That may be so but it cannot be said to be the effect of what law has amended. Tamarind will be imported only when it can be sold in the market here at the same price as the tamarind produced within the State. Only when after bearing the other ' State tax and freight charges	 if it is able to compete with the locally produced tamarind	 it will normally be imported from outside the State. If there is any difference in prices because of market conditions and other factors	 that cannot be said to be due to discrimination prohibited by clause (a) of article 304 of the Constitution. In order to ensure this	 it would be necessary that imported goods must always be taxed at a lower rate than the corresponding goods within the State because of freight and other charges. That cannot be so. The High Court observed that tamarind is an agricultural produce and that is why it was put in Second Schedule i.e. to say	 purchase point	 but where it was imported and sold within the State	 there was no reason to tax it at the sale point. We are of the opinion that the. High Court was 'right. It was contended on behalf of the appellants before the High Court that imported tamarind which had suffered tax at the first sale point	 will again be taxed at the purchase point when purchased within the State	 which would amount to double taxation. Once the imported tamarind is taxed at the first sale point under the First Schedule	 there is no occasion for taxing it over again at the sale point under the Second Schedule. The idea of both the Schedules is to tax only at one point 428 though the point of taxability may be different under dif ferent Schedules. Our attention was drawn on behalf of the appellants to a decision of this Court in Indian Cement Ltd. & Ors. vs State of Andhra Pradesh & Ors.	 69 STC 305. There this Court was concerned with Andhra Pradesh General Sales Tax Act. It appears that in exercise of its powers u/s 9(1) of the Act	 the State Government had passed a notification on January 27	 1987 reducing the rate of sales tax on sale of cement from 13.75% to 4% in respect of cement manufactured by cement factories situated in the State and sold to manufac turing units situated within the State for the purpose of manufacture of cement products such as cement sheets	 asbes tos sheets	 cement flooring stones	 cement concrete pipes	 cement water and sanitary fittings	 concrete poles etc. On the same day the State Govt. had passed another notification u/s 8(5) of the reducing the rate of tax on inter State sale of cement to 2% with or without Form C. On February 28	 1987 the State of Karnataka passed a similar notification reducing the rate of tax on inter State sale of cement from 15% to 2%. The petitioners	 of whom some were manufacturers of cement having their manufacturing units in Tamil Nadu and others	 were stockists having places of business in the States of Karnataka	 Kerala and Tamil Nadu	 filed writ petitions before this Court challenging the validity of these notifications on the ground that these created trade barriers and directly im pinged upon the freedom of trade	 commerce and intercourse provided for in article 301 of the Constitution of India. It was held that the variations in the rates of local and inter State sales tax affected free trade and commerce and created a local preference	 which was contrary to the scheme of Part XIII of the Constitution of India; and as such the notification were bad. This decision was rendered in the peculiar facts of that case. While the principle enunciated by the Court in the said decision there can be no dispute that taxation was a deterrent in some cases	 against free flow of trade	 and as a result of favourable or unfavourable treatment by way of taxation	 the course of flow of trade gets regulated either adversely or favourably	 and that if the scheme of Part XIII guarantees has to be preserved in the national interest	 it is imperative that the provisions of article 301 must be strictly complied with	 we are of the opinion that the ratio of the said decision in the facts and circumstances of this case would not be relevant. In our opinion	 the provisions of the Constitution should be strictly complied with not only with the letter but also with their spirit. Part XIII of the Constitution has to 429 be dealt with the other provisions of the Constitution. Our attention was drawn to the observations of this Court in M/s Associated Tanners	 Vizianagaram	 A.P. vs C.T.O.	 Vizianaga ram. A.P. & Ors.	 ; It was reiterated there that the effect of an imposition of tax may work differently upon different dealers	 namely	 those who import goods and those who purchase the goods locally. That effect cannot be said to arise directly or as an immediate effect of the imposition of tax. It cannot be said that there was any violation of clause (a) of article 304 of the Constitution. We are of the opinion that in the instant case the difference	 in rates	 if any	 between the imported tamarind and locally produced tamarind is not as an immediate or direct result of the imposition of tax. The decision of this Court in Weston Electronics & Anr. vs State of Gujarat & Anr. 	 ; dealt	 in our opinion	 with an en tirely different situation and for the purpose of the in stant controversy	 cannot be of any assistance. Mr. C. Sitaramiah	 appearing for the respondents	 drew our attention to Rattan Lal & Co. & Anr. vs The Assessing Authority & Anr.	 ; wherein this Court had reiterated that when a taxing State is not imposing rates of tax on imported goods different from rates of tax on goods manufactured or produced	 article 304 has no application. So long as the rate is the same article 304 is satisfied. In the instant case the tax is at the same rate and	 hence	 tax cannot be said to be higher in the case of imported goods. When the rate is applied the resulting tax may be somewhat higher but that does not contravene the equality contemplat ed by article 304 of the Constitution. In the facts and the circumstances of the case	 there is no ground to complain about the breach of article 14 of the Constitution. In the aforesaid view of the matter	 we are of the opinion that the High Court was right in the view it took and this appeal must fail. The appeal is accordingly dis missed. In the facts and the circumstances of the case	 however	 we make no order as to costs. P.S.S. Appeal dismissed.

Under item 14 of Second Schedule to the Andhra Pradesh General Sales Tax Act	 1957 tamarind was subjected to sales tax at the point of first purchase in the State irrespective of whether it was purchased within the State or outside the State. However	 by virtue of an amendment to the Act by Act 19 of 1986 tamarind which is purchased within the State was retained in Second Schedule	 while tamarind purchased out side the State was transferred to First Schedule as item 170	 making it taxable at the same rate at the point of first sale in the State. The appellants had purchased tamarind from the State of Orissa paying tax there and incurred expenditure in bringing it to Andhra Pradesh for sale. They challenged the said amendment modifying the point of taxability as discriminato ry between tamarind produced and purchased within the State and the tamarind produced and purchased outside the State and as such	 violative of Articles 304(a) and 14 of the Constitution. The submission was that imported tamarind which had suffered tax at the first sale point will again be taxed at the purchase point when purchased within the State	 which would amount to double taxation	 and that tax in case of imported tamarind would be more because its price will include freight charges and other State taxes. The High Court found that there was no discrimination. Dismissing the appeal by special leave	 the Court	 423 HELD: When a taxing State is not imposing rates of tax on imported goods different from rates of tax on goods manufactured or produced	 Article 304 of the Constitution has no application. In the instant case	 both tamarind purchased within	 and outside	 the State was taxed uniform ly. There was. therefore	 no infraction of clause (a) of Article 304 of the Constitution. [429D E; 426A; 425G H] Rattan Lal & Co. & Anr. vs The Assessing Authority & Anr. 	 ; 	 applied. Firm A.T.B. Mehtao Majid & Co. vs The State of Madras	 14 STC 355 and Indian Cement Ltd. & Ors. vs State of Andhra Pradesh & Ors.	 69 STC 305	 distinguished. It may be that when the rate is applied the resulting tax in respect of imported tamarind may be somewhat higher because its price will include freight charges and other State taxes. But that cannot be said to be the effect of what law has amended. Tamarind will be imported only when it can be sold in the market at the same price as the tamarind produced within the State. Only when after bearing the other State taxes and freight charges	 if it is able to compete with the locally produced tamarind it will normally be imported from outside the State. If there is any difference in prices because of market conditions and other factors	 that cannot be said to be due to discrimination prohibited by clause (a) of Article 304.

Once the imported tamarind is taxed at the first sale point under the First Schedule there is no occasion for taxing it over again at the sale point under the Second Schedule. The idea of both the Schedules is to tax only at one point	 though the point of taxability is different in both the cases. In case of tamarind purchased within the State	 i.e.	 produced within the State	 the tax is levied at the point of first purchase under the Second Schedule	 and in case of imported tamarind i.e.	 purchased outside the State	 the tax is levied at the point of first sale in the State under the First Schedule. It could not therefore	 be said that taxing the imported tamarind at the point of first sale in the State would amount to double taxation. [427H; 428A; 427B C; 427G] 424 In the facts and circumstances of the case	 there was	 therefore	 no ground to complain about the breach of Article 14 of the Constitution [429E F]
