Examine whether income alone can be a reliable indicator of 'backwardness' among OBCs, in light of the Supreme Court's status-based interpretation of creamy layer exclusion.

The creamy layer, mandated by Indra Sawhney (1992) under Article 16(4), excludes socially advanced sections among OBCs from the 27% central quota. Whether a monetary ceiling can capture "backwardness" is contested — the Supreme Court's status-based reading indicates that income is at best a partial test.

Why income is used as a proxy

• Objectivity and ease of verification: a parental gross annual income ceiling is simple to administer across recruitment cycles.
• Periodic rationalisation: the limit was raised from ₹6 lakh to ₹8 lakh in 2017, keeping pace with the Consumer Price Index [2].
• It broadly tracks economic mobility, which can dilute disadvantage within a generation.

Why income alone is unreliable

• Backwardness under Article 16(4) is social and educational, not merely economic; income measures purchasing power, not caste-linked exclusion from networks, land and education.
• The Supreme Court has held that income from salary or agriculture alone cannot be the criterion for creamy layer status [1] — hence such income is kept outside the ceiling computation.
• A Class III employee's household crossing the ceiling is not socially advanced; the Standing Committee on Welfare of OBCs accordingly recommended exempting all Class III employees and not excluding children of parents entering Class I service after 40 [1].
• A uniform national ceiling ignores rural–urban and inter-state cost-of-living differences.
• Mechanical application of the income layer by the DoPT has generated prolonged litigation over OBC candidates excluded from the Civil Services Examination.

The status test as corrective

• Exclusion turns on parental post/occupation — constitutional functionaries, Group A/B officers — under the notified creamy layer schedule [3].
• The Cabinet approved equivalence of posts in PSUs, banks and insurance institutions with government posts, so children of those in lower categories retain OBC benefits [4].

Income is therefore a necessary but insufficient filter, best retained for non-salaried wealth within a status-based framework. Periodic revision of the ceiling, clear cross-sector post-equivalence, and alignment of DoPT rules with judicial precedent would ensure reservation reaches the genuinely disadvantaged, advancing the substantive equality Article 16(4) promises.
