Summarize the following court judgment. Petitions (Civil) Nos. 5117/ 81	 7340/81	 3656 84/82	 6381 82	 6951 52/82	 8010 19/82	 8108 11/82	 90 19 20/82	 5241 60/83	 1734 35/83 and 559 560/83. (Under Article 32 of the Constitution of India). B. Kanta Rao for the Petitioners. C. Seetharamiah	 T.V.S.N. Chari	 Ms. Vrinda Grover	 Ch. Badri Nath	 A.K. Sanghi	 G.S. Chatterjee P.N. Mishra	 A.V Rangam	 Pramod Swarup	 D. Goburdhan and M.N. Shroff for the Respondents. The Judgment of the Court was delivered by SABYASACHI MUKHARJI	 J. W.P. Nos: 5117/81	 3656 84/82	 5241 5260/83. & 7340/81 These four batches of Writ Petitions challenge the imposition of sales tax on bread	 rusk and bun under the A.P. Sales Tax Act 1957 as illegal. The main and the first contention was that the bread and biscuits belong to one homogeneous class but these have been differently treated for taxation under Schedule I	 Item No. 117 and Schedule I	 Item No. 129 of the said Act. In other words	 the contention of the petitioners is that the bread and biscuits are the same	 they should not be differently taxed. The purchasers and sellers of bread and biscuits have been differently taxed In support of this contention reliance was placed on certain decisions of this Court	 namely: State of Andhra Pradesh & Anr. vs Nalla Raja Reddy & Ors.	 ; ; New Manek Chowk Spinning and Weaving Mills Co. Ltd. and Ors. vs Municipal Corporation of the City of Ahmedabad and others; 	 We do not find any proposition in those decisions in support of this contention of the petitioners. The decision of the Allahabad High Court in Annapurna Biscuit (Mfg.) Co. and Another vs The State of U.P. and Another	 [1975] 35 S.T.C. 9 127 does not deal with this contention at all. A The second contention sought to be raised was that the multiple point tax violates Article 19(1)(g) of the Constitution. The petitioners being Bakeries	 this contention is not open to the petitioners. The third contention sought to be raised was that excise duty and sales tax are imposed on the same items. This also does not arise in the case of the petitioners who are Bakeries. Apart from that the taxable events in these two impositions are different. So this contention cannot in any event be raised. The fourth contention sought to be raised was the surcharge. This point in our opinion does not arise. Furthermore this point is concluded by the observations of this Court in the case of Hoechst Pharmaceuticals Ltd and Another Etc. vs State of Bihar and others	 [1983] 3 S.C.R. 130. Indeed all these contentions raised on behalf of the petitioners have been negatived by this Court in the aforesaid decision. We reiterate that the economic wisdom of a tax or lack of it are within the exclusive domain of the legislature. The only question for the Court to consider it whether there is rationality in that behalf of the legislature that capacity to pay the tax increases by and large with an increase of receipts. From any point of view there is rationality in this proposition. It is sound commonsense. It is in consonance with social justice to which we are committed by our Constitution. In that view of the matter the challenge to the imposition under Article 14 as well as Article 19(1)(g) of the Constitution are not sustainable. These Writ Petitions must fail and are dismissed accordingly. There will be no order as to costs. Interim orders	 if any	 are vacated W.P. Nos. 6381 82/82	 6951 52/82	 8010 19/82 8108 11/82	 9019 20/ 82	 1734 35/83 & 559 560/83. In view of the Judgment in W.P. Nos. 5117/81	 3656 84/82	 524 1 5260/83 and 7340/8 1	 these petitions must also fail and are accordingly dismissed. There will be no order as to costs. N.P.V. Petitions dismissed.

% In a batch of Writ Petitions filed in this Court the petitioners challenged the imposition of sales tax and surcharge on bread	 rusk and bun under the A.P. Sales Tax Act	 1957 as illegal	 contending that bread and biscuits belonged to one homogeneous class but had been treated differently for purposes of taxation under Schedule 1	 Item No. 117 and Item No. 129 of the Act	 that the purchasers and sellers of bread and biscuits had been differently taxed	 and that the multiple point tax violated Article 19(1)(g) of the Constitution. Dismissing the writ petitions	 ^ HELD: The economic wisdom of a tax or lack of it are within the exclusive domain of the legislature. The only question for the Court to consider is whether there is rationality in that behalf of the legislature that capacity to pay the tax increased by and large with the increase of receipts. From any point of view	 there is rationality in this proposition. It is sound commonsense and is in consonance with social justice. Therefore	 the challenge to the imposition	 under Article 14 as well as Article 19(1)(g) of the Constitution is not sustainable.
