Creamy Layer Principle

The creamy layer principle excludes the socially advanced members of a backward class from reservation benefits so that benefits reach those who remain disadvantaged. It is primarily a rule of substantive equality, not merely an income or economic-poverty test.

Origin and rationale

The Supreme Court formulated the principle for Other Backward Classes in Indra Sawhney v. Union of India (1992) while interpreting Article 16(4). It reasoned that excluding the advanced sections helps identify the genuinely backward class and prevents reservation benefits from being concentrated among its better-placed members.

• Creamy-layer identification may consider constitutional or occupational status, social advancement and income; income alone does not fully determine backwardness.
• The principle applies to OBC reservation in public employment and has also been applied to OBC reservation in educational institutions.

Position concerning Scheduled Castes and Scheduled Tribes

Indra Sawhney did not apply the OBC creamy-layer rule to SCs and STs. However, Jarnail Singh v. Lachhmi Narain Gupta (2018) treated exclusion of the creamy layer as an equality requirement in the specific context of reservation in promotion under Article 16(4A).

• The judgment did not convert SC and ST status into a purely income-based classification.
• It should not be read as establishing a uniform creamy-layer exclusion for every form of SC and ST reservation.

Later judicial development and key distinction

In State of Punjab v. Davinder Singh (2024), the Supreme Court permitted sub-classification within SCs and STs to distribute reservation benefits more effectively. Several concurring opinions favoured identifying advanced sections, but no uniform nationwide creamy-layer test for SCs and STs was prescribed.

• Sub-classification separates groups within a reserved category according to relative disadvantage; creamy-layer exclusion removes advanced individuals or sections from benefits.
• Both ideas seek more equitable distribution, but they are legally distinct.
