Summarize the following court judgment. CIVIL Appeal No. 4160 of 1985. 852 From the Judgment and Order dated 25.6.1984 of the Kerala High Court in T.R.C. No. 19 of 1984. V. J. Francis for the Appellant. T. M. Ansari	 Markose Vellapally and D. N. Misra for the Respondent. The Judgment of the Court was delivered by BHAGWATI	 J. The sole question which arises for determination in this appeal is as to what is the rate at which the goods which had been purchased earlier and which were in stock with the assessee on 30 6 74 were assessable to purchase tax when the purchases were found to be last purchases as a result of events which took place subsequent to 30.6.1974. This question has become material since the rate of purchase tax was increased from 3% to 5% with effect from 1st July	 1974. Now it is not disputed in the present case that the purchases of goods effected by the assessee prior to 30 6 74 were last purchases within the State because the goods purchased which were in stock on 30.6.74 were subsequently sold by the assessee in the course of inter state trade or commerce which means that they were not sold within the State and hence the assessee was clearly the last purchaser within the State and as such was liable to pay purchase tax under Item 71 of the First Schedule to the Kerala General Sales Tax Act. Equally it is clear that the assessee could not be made liable to tax on the purchases made by it prior to 30th June 1974	 unless the purchases acquired the quality of being last purchases in the State. It was pointed out by this Court in State of Madras vs Shri T. Narayanaswami Naidu & Anr.(1) when the assessee "files a return and declares the stock in hand	 the stock in hand cannot be said to have been acquired by last purchase because he may still during the next assessment year	 sell it or he may consume it himself or the goods may be destroyed	 etc. He would be entitled to claim before the assessing authorities that the character of acquisition of the stock in hand was undermined; in the light of subsequent events it may or may not become the last purchase inside the State. " There can therefore be no doubt that the assessee in the present case became liable to pay tax on the purchases made by it prior to 30th June	 1974	 as soon as it became determined though subsequent to 30th June 1974	 that these purchases were last purchases inside the State and were consequently exigible to tax. (1) ; 853 But the question remains as to what is the rate at which the A assessee was liable to be taxed in respect of these purchases. Since the purchases took place before 30th June 1974	 the assessee would	 in our opinion	 liable to be taxed at the rate prevailing at the time when the purchases were made and since the rate at the time was 3% of the sale price	 the High Court was right in taking the view that the purchases made by the assessee prior to 30th June 1974 were taxable at the rate of 3%. We may point out that a similar view has been taken by the Kerala High Court in Seaso Rubbers vs State of Kerala(1). We find ourselves in agreement with the reasoning adopted by the Full Bench of the High Court in that case. We accordingly reject the appeal but with no order as to costs.

The respondent assessee had made certain purchases before 30th June	 1974 and sold them subsequently in the course of inter state trade or commerce. The rate of purchase tax under Item 71 of the First Schedule to the Kerala General Sales Tax was increased from 3% to 5% with effect from 1st July	 1974. The High Court held that the purchases made by the respondent prior to 30th June	 1974 were taxable at the rate of 3 %. Dismissing the appeal to this Court	 ^ HELD: The assessee could not be made liable to tax on the purchases made by it prior to 30th June	 1974	 unless the purchases acquired the quality of being last purchases in the State In the instant case there can be no doubt that the assessee became liable to pay tax on the purchases made by it prior to 30th June	 1974	 as soon as it became determined though subsequent to 30th June	 1974	 that these purchases were last purchases inside the State and were subsequently eligible to tax. Since the purchases took place before 30th June	 1974	 the assessee would be liable to be taxed at the rate of 3% which was prevailing at the time when the purchases were made.
