Keshavan Madhava Menon v. The State of Bombay: A Landmark Case on Pre-Constitutional Laws and Fundamental Rights

This landmark case from 1951 grapples with a crucial question for the Indian Judiciary: Do pre-existing laws automatically become void when they conflict with the fundamental rights enshrined in the Constitution? Let’s delve into the details of this case to understand its significance for Judiciary aspirants.

Understanding the Context

  • Pre-Constitutional Laws: 

The Constitution of India came into effect in 1950. This case deals with laws enacted before 1950.

  • Fundamental Rights: 

Part III of the Constitution outlines fundamental rights guaranteed to all Indian citizens.

The Dispute

  • The petitioner, Keshavan Madhava Menon, published a pamphlet in 1949.
  • The pamphlet allegedly violated the Indian Press Emergency Powers Act, 1931, a pre-Constitution law.
  • When the Constitution came into force, Menon challenged the Act’s validity, arguing it infringed upon his freedom of speech under Article 19(1)(a).

Key Issues

  • Retrospective Effect of Article 13: 

Does Article 13(1), which voids laws inconsistent with fundamental rights, apply to pre-Constitution laws?

  • Validity of Pending Proceedings: 

Would ongoing legal proceedings based on pre-Constitution laws become invalid due to the Constitution’s enforcement?

Court’s Observations

  • Justice Sudhi Ranjan Das:
    • Article 13(1) has no retrospective effect. It applies only to future laws.
    • Pre-Constitution laws aren’t entirely void; only the parts contradicting fundamental rights are invalid.
    • The Constitution doesn’t prevent prosecution for offenses committed before its commencement.
  • Justices Saiyid Fazl Ali and B.K. Mukherjea:
    • The intended scope of Article 13(1) was debated during the Constitution’s drafting.
    • While the initial draft proposed abrogation of conflicting laws, the final wording used “void” with a specific meaning.
    • A law rendered void cannot be the basis for new charges or convictions.
  • Justice M.C. Mahajan:
    • Fundamental rights like freedom of speech weren’t guaranteed before the Constitution.
    • Repealing a law doesn’t erase its past application. People were liable under the Act when it was in force.

The Verdict

The Court dismissed Menon’s petitions. Pre-Constitution laws remain valid unless they directly conflict with fundamental rights. The ongoing proceedings against Menon could continue under the pre-existing Act.


The Keshavan Madhava Menon case established a vital precedent for reconciling pre-existing laws with the Constitution’s fundamental rights. It clarified that Article 13(1) applies prospectively and doesn’t invalidate past actions taken under pre-Constitution laws. This case serves as a crucial reference point for understanding the interplay between pre-existing legal frameworks and the fundamental rights enshrined in the Indian Constitution.
