Assistant Commissioner of Agricultural Income Tax & Ors. v. M/s. Netley 'B' Estate & Ors.
Background
Under the Karnataka Agricultural Income Tax Act, a Karnataka High Court ruling (Cardoza's case) had held that once a firm is dissolved, it ceases to exist in law and cannot be taxed on agricultural income actually received after dissolution, even if that income related to produce sold before dissolution: such income could only be taxed in the hands of whoever actually received it. The Karnataka legislature responded by retrospectively amending Section 26(4) (effective from 1975) to add an Explanation deeming a dissolved firm to continue existing, for tax purposes, in respect of such income. Assessee-firms challenged this retrospective amendment, and a Division Bench of the High Court struck it down, holding it unconstitutionally nullified the Cardoza judgment.
Decision Breakdown
The Supreme Court held that a legislature cannot directly overrule a court's judgment, but it can validly render a judgment ineffective for the future by retrospectively altering the very legal foundation on which that judgment was based, which is exactly what happened here. Distinguishing the precedent relied on by the High Court (D. Cawasji & Co., where a steep retrospective tax hike was struck down because it was arbitrary and merely sought to escape a refund without curing any real defect), the Court found that here the legislature had genuinely changed the substantive basis of assessment, making dissolved firms deemed-assessees for specific post-dissolution receipts, rather than simply nullifying the earlier ruling outright. Since this was a legitimate and complete legislative change to the law's foundation, not an arbitrary or disguised attempt to defeat a vested right, the amendment was valid. The Court set aside the High Court's judgment and allowed all the Revenue's appeals.
Lesson Learnt
A legislature is free to retrospectively change the law to remove the very basis of an unfavourable court ruling (even many years later), and such a change is constitutionally valid: what it cannot do is simply declare, by naked legislative fiat, that a specific past judicial decision is overruled or does not bind the parties.
