Jarnail Singh v. Lachhmi Narain Gupta

The story

For over a decade, government employees and states had wrestled with the fallout of the 2006 Nagaraj ruling, which conditioned SC/ST promotion quotas on proving 'backwardness' with hard data—a task many states found impractical and litigation-prone. Employees denied promotions, and states struggling to implement quotas, brought the fight back to the Supreme Court, asking a five-judge bench to revisit these conditions. At the heart of the case lay a human tension: hundreds of thousands of SC/ST employees waiting for promotions promised by the Constitution, pitted against general category employees who felt reservations needed real accountability. In 2018, the Constitution Bench, led by Justice Rohinton Nariman, delivered a nuanced verdict—it freed states from the burden of proving backwardness through data, since the Constitution itself had already recognized SC/STs as historically disadvantaged. Yet the Court did not open the floodgates entirely: it insisted, borrowing from the older Indra Sawhney ruling, that the 'creamy layer'—the relatively advantaged among SC/STs—must be excluded from promotional benefits. The judgment reshaped affirmative action policy in government service, balancing constitutional commitment to social justice with a demand for genuine equity within reserved categories, ensuring the neediest, not the already-advantaged, received the intended benefit.

The facts

The case arose from a reference to a five-judge Constitution Bench to reconsider certain conclusions in M. Nagaraj v. Union of India (2006), which had upheld the constitutional validity of Articles 16(4A) and 16(4B) but imposed conditions on states before granting reservation in promotions to SC/ST employees. Various state governments and litigants challenged the requirement in Nagaraj that the state must collect quantifiable data showing the backwardness of SC/STs before providing reservation in promotions, arguing this was onerous and unnecessary since SC/STs are constitutionally presumed backward. The dispute involved competing claims of general category and SC/ST employees over promotional reservation policies in various government departments.

The question before the court

Whether the requirement laid down in M. Nagaraj (2006) that states must collect quantifiable data demonstrating the backwardness of SC/STs before granting reservation in promotions needs reconsideration by a larger bench, and whether the 'creamy layer' exclusion principle applies to SC/ST reservations in promotions.

The holding

The Constitution Bench held that the requirement in M. Nagaraj directing states to collect quantifiable data on the backwardness of Scheduled Castes and Scheduled Tribes before granting reservation in promotions is invalid and contrary to the nine-judge bench decision in Indra Sawhney, since SC/STs are already declared backward under the Constitution (via Presidential lists under Articles 341 and 342) and do not need to separately prove backwardness. However, the Court retained the requirement that the state must still show inadequacy of representation of SC/STs in the relevant cadre and that reservation in promotion does not affect overall administrative efficiency. The Court further held that the 'creamy layer' principle, previously applied to identify and exclude the advanced sections of Other Backward Classes from reservation benefits, also applies to Scheduled Castes and Scheduled Tribes for the purpose of promotional reservations, meaning that the creamy layer among SC/STs must be excluded from the benefit of reservation in promotions.

The principle it stands for

For reservation in promotions under Article 16(4A), the state need not collect quantifiable data to prove the backwardness of SC/STs since their backwardness is constitutionally presumed, but it must still demonstrate inadequacy of representation and protect administrative efficiency. The creamy layer exclusion principle, evolved for OBCs in Indra Sawhney, extends equally to SC/ST candidates in the context of promotional reservations to ensure that only the truly disadvantaged among them benefit.

Provisions this case shaped

• Art. 335Claims of Scheduled Castes and Scheduled Tribes to services and postsinterpreted — Reaffirmed that efficiency of administration must be maintained while allowing reservation in promotions.
• Art. 16Equality of opportunity in matters of public employmentinterpreted — Clarified scope of reservation in promotions under Article 16(4A) read with Article 16(4).
• Art. 341Scheduled Castesinterpreted — Held SC status under Presidential lists already establishes backwardness, no separate proof needed.
• Art. 342Scheduled Tribesinterpreted — Held ST status under Presidential lists already establishes backwardness, no separate proof needed.
