From the resolution of contentious issues regarding distribution of legislative powers by the courts, Principle of Federal Supremacy and Harmonious Construction have emerged. Explain.

In short

When legislative entries overlap, courts first read them harmoniously so each operates in its own field, and only if conflict is irreconcilable does the Union law prevail under Articles 246(1) and 254. Mineral Area Development Authority v. SAIL (2024) reconciled the Union's mining entry with the states' power to tax mineral rights.

Model answer

Ghissu Editorial · Verified 4 Oct 2026

Introduction
The Seventh Schedule's three lists inevitably overlap. In Mineral Area Development Authority v. SAIL (2024), a nine-judge bench reconciled the Union's mining entry with the states' power to tax mineral rights, showing the two principles courts use: harmonious construction first, federal supremacy as the last resort.
Principle of Federal Supremacy
•

Textual basis

Article 246(1) gives Parliament power over the Union List "notwithstanding" clauses (2) and (3), so in an irreconcilable overlap the Union entry prevails.

•

Concurrent repugnancy

Under Article 254(1) a central law prevails over a conflicting state law, judged by the M. Karunanidhi (1979) tests, though Article 254(2) saves a state law that receives the President's assent.

•

Applied

In Adhiyaman Educational Institute (1995), Tamil Nadu's rules on technical education gave way to the AICTE Act, made under the Union entry on coordination and standards.

Principle of Harmonious Construction
•

Reconcile first

Courts identify a law's pith and substance and read overlapping entries so that each operates in its own field, because the lists are meant to coexist and no entry should be rendered meaningless.

•

Classic illustration

The Federal Court's motor spirit case (1939) upheld both the federal excise on manufacture and the provincial tax on sale.

•

Reading together

Gujarat University v. Mudholkar (1963) let a state set the medium of instruction only so far as the Union's power over standards was unaffected.

Conclusion
Together the principles let a strong Centre coexist with meaningful state autonomy, keeping the division of powers flexible and the Union cohesive in the spirit of cooperative federalism.
