Mandal Commission and Indra Sawhney v UOI

Mandal Commission OBC reservation became the subject of one of independent India's most consequential constitutional battles when the government's decision to reserve 27% of central government jobs for Other Backward Classes was challenged before the Supreme Court. The resulting judgment, Indra Sawhney v. Union of India (1992), popularly called the Mandal case, laid down the framework that still governs OBC reservation in public employment today.

What the Case Was About

The dispute arose over an executive order implementing 27% reservation in central government jobs for Other Backward Classes, invoking Article 16(4) of the Constitution, which permits the State to make provision for the reservation of appointments in favour of any backward class of citizens that is not adequately represented in State services. The core questions before the Court concerned the outer limit of such reservation, the scope of "backward class," and whether reservation could extend to promotions.

The Supreme Court's Ruling

In 1992, the Supreme Court upheld the validity of the 27% OBC reservation under Article 16(4), but subject to a set of conditions that continue to define the boundaries of reservation law:

Aftermath: Constitutional Amendments Responding to the Judgment

Several of the conditions laid down in the Mandal case proved contentious, particularly the bar on promotion-based reservation. Parliament responded through a series of constitutional amendments that modified the reservation framework for Scheduled Castes and Scheduled Tribes:

These amendments were later challenged, and the Supreme Court upheld their constitutional validity, holding that Articles 16(4A) and 16(4B) flow from Article 16(4) itself and do not alter its basic structure. The Court held that the amendments retained the underlying requirements of backwardness and inadequacy of representation that justify reservation, subject to the overall efficiency of administration under Article 335, and that they applied only to Scheduled Castes and Scheduled Tribes. Importantly, the ruling clarified that the 50% ceiling, the creamy layer concept, and the distinction between OBCs on one hand and SCs/STs on the other — as laid down in the Mandal case — continued to hold for OBCs.

Why It Matters

The Mandal case remains the foundational precedent on the scope and limits of reservation under Article 16(4). It fixed the 50% ceiling and the creamy layer principle as durable constitutional standards for OBC reservation, while the subsequent constitutional amendments show how Parliament can calibrate the framework for SCs and STs — particularly on promotion — without disturbing the core principles the Court laid down.
