Introduction
Article 14 guarantees equality before the law and equal protection of the laws. While it forbids class legislation, it permits reasonable classification provided it satisfies the twin test established in State of West Bengal v. Anwar Ali Sarkar (1952): intelligible differentia and a rational nexus to the legislative objective. Over the decades, the Supreme Court has evolved beyond this formalistic inquiry toward substantive scrutiny under the doctrine of manifest arbitrariness.
Evolution of the Manifest Arbitrariness Test
- E.P. Royappa v. State of Tamil Nadu (1974): Justice P.N. Bhagwati propounded that equality is a dynamic concept, declaring equality and arbitrariness as 'sworn enemies.' This established non-arbitrariness as an intrinsic guarantee of Article 14 in administrative matters.
- State of A.P. v. McDowell & Co. (1996): The Supreme Court restricted the doctrine, holding that plenary legislation enacted by Parliament or State Legislatures cannot be struck down merely on grounds of arbitrariness, requiring explicit constitutional infractions instead.
- Shayara Bano v. Union of India (2017): The Court settled the debate and overruled the restrictive approach in McDowell. It held that primary legislation lacking an 'adequate determining principle' or acting capriciously and irrationally can be invalidated under Article 14 for 'manifest arbitrariness.'
Contemporary Applications of the Doctrine
- Navtej Singh Johar v. Union of India (2018): The Supreme Court struck down Section 377 of the Indian Penal Code to the extent it criminalised consensual same-sex acts between adults, terming it manifestly arbitrary.
- Joseph Shine v. Union of India (2018): Section 497 of the IPC (Adultery) was invalidated on the grounds of manifesting an arbitrary, patriarchal classification that denied women agency.
Critical Analysis and the Proportionality Standard
While the manifest arbitrariness standard empowers the judiciary to protect constitutional values, critics argue that it carries the risk of judicial subjectivism—substituting legislative wisdom with judicial discretion. To provide objective boundaries, the Court increasingly fuses manifest arbitrariness with the Doctrine of Proportionality (as applied in Gujarat Mazdoor Sabha v. State of Gujarat, 2020), demanding a structured assessment of legitimate state aims, rational connection, minimal impairment, and balanced impact.
Conclusion
The evolution towards the manifest arbitrariness test marks a profound shift in Indian constitutional jurisprudence, transitioning Article 14 from formalistic equality to substantive equality. By pairing this standard with the doctrine of proportionality, the judiciary ensures that legislative and executive actions remain aligned with constitutional morality without descending into arbitrary exercise of state power.
