Vikram Cement & Anr. v. State of Madhya Pradesh & Ors.
Background
A cement manufacturer paid entry tax on raw materials (coal, gypsum, bauxite) brought into Madhya Pradesh at the then-prevailing higher rates. A later government notification retrospectively reduced the entry tax rate for a past period to just 1%, but added an "Explanation" stating that dealers who had already paid tax at the higher rate would not get any refund of the difference. The company challenged this Explanation as discriminatory and unconstitutional, but the Madhya Pradesh High Court dismissed its writ petition by simply following an earlier Division Bench ruling without separately examining the arguments.
Decision Breakdown
The Supreme Court held that the no-refund Explanation created an arbitrary and unjustified distinction between dealers who had faithfully paid tax at the higher rate and those who had defaulted and were later let off at the reduced rate: a classification with no intelligible differentia or rational nexus to any legitimate objective, violating Article 14's equality guarantee. The Court also held that once the lawful rate for the period was fixed at 1%, compelling anyone to bear a higher tax burden without refund violated Article 265, which bars collection of tax except by authority of law. The State's suggestion that the Explanation was meant to prevent "unjust enrichment" was rejected as unsupported by the record: that issue could be examined case-by-case at the refund-application stage, not presumed wholesale. The Court declared the Explanation in both relevant notifications unconstitutional, quashed it, and allowed the appeal.
Lesson Learnt
When the government retrospectively lowers a tax rate for a past period, it cannot lawfully bar refunds to those who already paid at the earlier, higher rate while letting defaulters benefit from the reduced rate, doing so is treated as unconstitutional discrimination and an unauthorized tax collection.
