Doctrine of Proportionality

The doctrine of proportionality is a method of judicial review used to determine whether a restriction on a Fundamental Right goes further than necessary to achieve a lawful public purpose. It requires a structured comparison between the State's objective, the means adopted and the harm caused to the right, rather than merely asking whether the restriction appears reasonable.

Constitutional setting

Fundamental Rights are not absolute, but restrictions must satisfy the conditions prescribed by the Constitution. Article 13 permits courts to invalidate laws that contravene Fundamental Rights, while Article 19(2)-19(6) expressly require specified restrictions to be reasonable. Under Article 21, State action must also follow a procedure that is just, fair and reasonable.

Four-stage proportionality test

The Supreme Court set out the structured test in Modern Dental College and Research Centre v. State of Madhya Pradesh (2016). Before applying it, the court examines whether the restriction has a valid legal basis.

• Legitimate purpose: The measure must pursue a constitutionally permissible and sufficiently important objective.
• Rational connection: The restriction must be capable of advancing that objective and cannot be arbitrary or unrelated to it.
• Necessity: Among equally effective measures, the State should choose the one that impairs the right least. This is the least-restrictive-means inquiry.
• Balancing: The social benefit of the measure must justify the seriousness of the harm imposed on the right. An excessive burden fails even if the measure has a rational connection to its purpose.

Judicial effect

If a measure fails any required stage, the court may hold the restriction unconstitutional, read it down or grant other appropriate relief. K.S. Puttaswamy v. Union of India (2017) applied proportionality to privacy and emphasized legality, a legitimate State aim and a proportionate relationship between means and ends.

• The doctrine subjects both the purpose and the intensity of rights-restricting State action to review.
• Its application remains sensitive to the text of the particular right and the constitutionally permitted grounds of restriction.
