The State of Madhya Pradesh and Others v. Lafarge Dealers Association and Others
Background
This batch of appeals concerned industrial units that had been granted sales-tax exemptions/deferments under the undivided State of Madhya Pradesh before it was split into Madhya Pradesh and Chhattisgarh in 2000. The dispute was whether such tax benefits, and the "intra-state" tax treatment of goods movement between units now sitting in two different states, continued after the bifurcation, or whether the new state boundary made such transactions "inter-state" and ended the benefit's cross-border reach. Conflicting High Court rulings and an earlier Supreme Court precedent (Swarn Rekha Cokes and Coals) had taken differing views, leading to this matter being referred to a larger bench for an authoritative ruling.
Decision Breakdown
The Supreme Court held that when a new state is constitutionally created, it is a distinct political and legal entity, and a reorganisation statute's provision for "continuity of laws" (to avoid a legal vacuum) does not mean the two successor states are treated as one for tax purposes. Consequently, what were formerly intra-state sales within undivided Madhya Pradesh became inter-state sales once Chhattisgarh was carved out, and the exemption/deferment benefit tied to the unit's original state did not automatically extend to the new inter-state trade. The Court expressly overruled the contrary reasoning in paragraphs 29-30 of its earlier Swarn Rekha Cokes decision, allowed the State's appeals, dismissed the private parties'/assessees' appeals, but left it open for affected parties to separately argue before tax authorities whether any distinct exemption existed for inter-state transactions.
Lesson Learnt
When a state is split into two, laws may continue to apply for continuity's sake, but this does not erase the new state's separate legal and political identity: benefits or tax treatments tied to the old single-state boundary do not automatically carry over to transactions that now cross the new inter-state line.
