Indian Supreme Court jurisprudence on RESERVATIONS includes:

1. RESERVATION JURISPRUDENCE in India has evolved significantly: 2. (i) INDRA SAWHNEY v UoI (1992) — 9-Judge Bench upheld 27% OBC reservation; laid down (a) 50% cap on reservation; (b) creamy layer principle for OBCs; (c) no reservation in promotions; 3. (ii) M. NAGARAJ v UoI (2006) — Constitution Bench upheld Article 16(4-A) (promotion reservation for SC/ST) subject to conditions: state must show (a) backwardness; (b) inadequate representation; (c) overall efficiency; 4. (iii) JARNAIL SINGH v LACHHMI NARAIN GUPTA (2018) — modified Nagaraj: no need to show backwardness for SC/ST (presumed); applied creamy layer to SC/ST promotions for first time; 5. (iv) JANHIT ABHIYAN v UoI (2023) — Constitution Bench upheld 103rd Amendment (10% EWS reservation), Articles 15(6) and 16(6). 6. CONTINUING DEBATES: extension of creamy layer to SC/ST in admissions; sub-classification of reserved categories. 7. Hence option B is correct. _Source: Legal Research Methodology + Jurisprudence — Reservation jurisprudence; Indra Sawhney; M Nagaraj; Janhit Abhiyan_
