The 77th Constitutional Amendment Act 1995 is an important constitutional amendment that strengthened India’s reservation framework in public employment. It was enacted to protect the interests of Scheduled Castes (SCs) and Scheduled Tribes (STs) in government services. The amendment inserted a new provision in Article 16 of the Constitution to allow reservation in promotions for these communities. This change was introduced after a Supreme Court judgement restricted such reservations, and it aimed to ensure their adequate representation in State services.
77th Constitutional Amendment Act
The 77th Constitutional Amendment Act also called- Constitution (Seventy-seventh Amendment) Act, 1995 was enacted by Parliament in the 46th Year of the Republic of India and officially published in the Gazette of India on 31 May 1995. It came into force on 17 June 1995. The amendment inserted clause (4A) into Article 16 of the Constitution to enable the State to provide reservation in promotion for Scheduled Castes and Scheduled Tribes in government services where their representation was considered inadequate.
Changes under 77th Constitutional Amendment Act
The 77th Constitutional Amendment Act introduced constitutional support for reservation in promotions for SCs and STs within State services.
- Insertion of Article 16(4A): The amendment added clause (4A) to Article 16 of the Constitution. This clause clearly states that the State can provide reservation in promotion for Scheduled Castes and Scheduled Tribes in government services if these groups are not adequately represented in public employment positions.
- Restoration of Promotion Reservation Policy: Reservation in promotion had been practiced administratively since 1955. However, the Supreme Court judgement in 1992 restricted reservation only to initial appointments. The 77th Amendment restored the earlier system by giving constitutional authority to the continuation of promotional reservations for SCs and STs.
- Protection of Representation in State Services: The amendment was based on the recognition that representation of Scheduled Castes and Scheduled Tribes in State services had not reached the desired level. The new provision enabled governments to adopt promotion reservations as a corrective measure to improve representation.
- Empowerment of State Governments: Article 16(4A) gave discretionary power to State governments to decide whether reservation in promotion should be implemented. The State can introduce such policies only when it believes that SCs and STs are inadequately represented in public services.
Case Laws related to 77th Constitutional Amendment Act
Several judicial decisions have examined the validity and implementation conditions of reservation in promotions under the 77th Constitutional Amendment Act.
- Indra Sawhney v. Union of India (1992): The Supreme Court held that Article 16(4) allows reservation only at the stage of initial appointment and not in promotions. The judgement also imposed a general ceiling of 50 percent on reservations in public employment, which influenced later constitutional changes.
- M. Nagaraj v. Union of India (2006): The Supreme Court upheld the constitutional validity of Article 16(4A). However, it directed States to satisfy certain conditions before granting promotion reservation, including proving inadequate representation of SCs and STs and ensuring administrative efficiency is maintained.
- Jarnail Singh v. Lachhmi Narain Gupta (2018): The Court reaffirmed the constitutional validity of promotion reservation provisions. It clarified aspects of the Nagaraj judgement and continued to support the framework established by the 77th Amendment while ensuring constitutional safeguards.
