Supreme Court Says Decades-Old Sales Tax Surcharge Reference Has Become Academic After GST

A seven-judge Constitution Bench of the Supreme Court held on Tuesday that a nearly three-decade-old reference on the power of state legislatures to levy an additional tax or surcharge calculated on sales tax has become academic following the introduction of the Goods and Services Tax regime. The bench had reserved its verdict earlier and delivered the judgment on November 4.

The bench examined earlier decisions, including longstanding precedents on the taxing powers of states, in the course of addressing the reference. The Court observed that an additional tax or surcharge computed as a percentage of sales tax payable amounted to an enhancement of the rate of sales tax under the then-applicable constitutional entry on taxes on the sale or purchase of goods.

Why it matters

With GST having subsumed the earlier sales-tax structure, the Court's finding that the reference is now moot closes a long-pending question of legislative competence without disturbing the current indirect-tax framework. The ruling clarifies the status of a reference that had been pending for years, settling its place in the post-GST legal landscape.

Constitution Bench references of this kind often linger for long stretches as the law around them evolves. By recognising that the underlying tax regime has changed fundamentally, the Court avoided reopening settled questions while tidying up a loose end left over from the pre-GST era.
