Introduction

Article 13 ensures that Fundamental Rights are protected from violation by laws.
It checks both old laws (before Constitution) and new laws made after it.
Any law violating Fundamental Rights can be declared void (invalid).

Meaning / Definition

Article 13 lays down that any law inconsistent (not matching) with Fundamental Rights shall be void to the extent of such inconsistency.

It mainly deals with:

• Validity of pre-Constitution laws
• Validity of post-Constitution laws
• Protection of Fundamental Rights

Modes or Types

Pre-Constitution Laws (Article 13(1))

• Laws made before 26 January 1950

• Continue to exist after Constitution

• But become void if they violate Fundamental Rights

• Important points:

  • Void only from the date of Constitution
  • Not invalid for past actions (not retrospective)

Prospective Nature

• Article 13(1) is prospective (applies to future)

• It does not affect past actions done before Constitution

• Rights and liabilities created before Constitution remain valid

Doctrine of Severability

• If only part of a law violates Fundamental Rights:

  • Only that part becomes void
  • Remaining valid part continues

• This is called severability (separation)

Validity of Procedure

• Even if past rights remain valid

• The procedure used after Constitution must follow Fundamental Rights

• Any unfair procedure becomes void after 1950

Important Case Law

Keshavan Madhava Menon v. State of Bombay

• Article 13 is not retrospective
• Law valid before Constitution remains valid for past acts

Lachmandas v. State of Maharashtra

• Procedure violating Fundamental Rights cannot continue after Constitution

Sub-Inspector Rooplal v. Lt. Governor

• Doctrine of severability applied
• Only offending part of law becomes void

Distinction / Comparison

Prospective vs Retrospective

• Prospective:

  • Applies only to future
  • Article 13 follows this

• Retrospective:

  • Applies to past actions
  • Article 13 does not follow this

Void vs Completely Invalid

• Void:

  • Invalid only to the extent of violation

• Completely Invalid:

  • Entire law becomes invalid

• Under Article 13 → Only part violating rights becomes void

Practical Example

A law made in 1930 denies education to a particular caste.
After 1950, this part becomes void because it violates equality under Fundamental Rights.

However, actions taken under that law before 1950 remain valid.

Summary

• Article 13 protects Fundamental Rights from violation by laws
• Pre-Constitution laws become void if inconsistent with rights
• Article 13 is prospective (applies to future, not past)
• Past actions under old laws remain valid
• Doctrine of severability allows removal of only invalid parts
• Courts ensure laws follow Fundamental Rights after 1950
