Under M. Nagaraj v Union of India (2006), a State making reservation in promotion for SCs and STs under Article 16(4A) had to show backwardness of the class, inadequacy of representation and maintenance of administrative efficiency under Article 335. The fifty per cent limit was not applied to each year's vacancies in isolation, because Article 16(4B) lets carried-forward backlog vacancies be treated as a separate class. So "Not crossing of 50% ceiling in a particular year" was not a requirement.

Current law: Jarnail Singh v Lachhmi Narain Gupta (2018) held that the State need not collect quantifiable data to show the backwardness of SCs and STs; inadequacy of representation and administrative efficiency remain relevant.
