Article 16: Equality of opportunity in matters of public employment

In plain words

All citizens have equality of opportunity in public employment. No citizen can be ineligible or discriminated against for a government job only on grounds of religion, race, caste, sex, descent, place of birth or residence.

  • Parliament can prescribe residence requirements for certain posts in a State or Union territory.
  • The State can reserve posts for backward classes not adequately represented, and reserve promotions (with consequential seniority) for the Scheduled Castes and Scheduled Tribes.
  • Unfilled reserved vacancies can be carried forward, without counting towards the fifty per cent ceiling for that year.
  • Posts can be reserved for economically weaker sections, up to a maximum of ten per cent, in addition to existing reservations.
  • Offices in religious or denominational institutions can be limited to followers of that religion.

Understanding this article

Article 16 guarantees equality of opportunity in public employment. No citizen can be discriminated against in State employment on grounds of religion, race, caste, sex, descent, place of birth or residence. It also permits reservation in appointments and promotions, which has made it one of the most litigated provisions in the Constitution.

The structure

  • Clause (1): equality of opportunity in public employment.
  • Clause (2): no discrimination on listed grounds, including descent and residence.
  • Clause (3): Parliament may require residence for certain posts.
  • Clause (4): reservation for backward classes not adequately represented.
  • Clauses (4A) and (4B): reservation in promotion for SCs and STs, and carrying forward unfilled reserved vacancies.
  • Clause (6): reservation for economically weaker sections, up to ten per cent.

Key principles from the case law

  • Reservation should ordinarily not exceed fifty per cent, save in extraordinary situations.
  • The creamy layer of backward classes must be excluded from reservation benefits.
  • Reservation in promotion for SCs and STs is permissible, but the State must ensure administrative efficiency (Article 335), and the creamy layer principle can apply.
  • SCs may be sub-classified for more beneficial treatment of the more backward among them, based on data.

Article 16(4) is not an exception

Reservation under Article 16(4) is treated as a facet of equality, not an exception to it. Formal equality is supplemented by substantive equality for those historically excluded.

Key Supreme Court rulings

  • Indra Sawhney v. Union of India 1992 Supp (3) SCC 217

    A nine judge bench upheld OBC reservation but required exclusion of the creamy layer and laid down that reservation should not ordinarily exceed fifty per cent.

  • M. Nagaraj v. Union of India 2006 INSC 711

    Upheld Articles 16(4A) and 16(4B) on reservation in promotion, holding equality to be a basic feature, while requiring the State to satisfy conditions before providing such reservation.

  • Jarnail Singh v. Lachhmi Narain Gupta 2018 INSC 881

    Held that M. Nagaraj's requirement of quantifiable data showing backwardness of SCs and STs was contrary to Indra Sawhney and invalid to that extent, and that the creamy layer principle can be applied to SCs and STs.

  • The State of Punjab v. Davinder Singh 2024 INSC 562

    By majority, sub-classification of Scheduled Castes for reservation is constitutionally permissible; E.V. Chinnaiah, which held otherwise, was overruled.

Common mistakes

  • Calling Article 16(4) an exception to equality.
  • Forgetting the creamy layer exclusion.
  • Relying on Chinnaiah, which has been overruled on sub-classification.
