NCST composition and functions are laid down in Article 338A of the Constitution, which creates the National Commission for Scheduled Tribes as an independent constitutional watchdog for the safeguards, rights, and socio-economic development of Scheduled Tribes across India. Unlike a statutory body created by ordinary legislation, the NCST derives its existence directly from the Constitution, giving it a standing that a body created by Parliament alone would not have.

Origin and Constitutional Basis

Before 2004, Scheduled Castes and Scheduled Tribes were both covered by a single body under Article 338. The Constitution (Sixty-fifth Amendment) Act, 1990 had already reshaped that article, renumbering its clauses and converting the earlier arrangement into a proper multi-member commission. Then the Constitution (Eighty-ninth Amendment) Act, 2003 went a step further: it split the combined commission into two separate constitutional bodies. The words "and Scheduled Tribes" were dropped from Article 338, and a new Article 338A was inserted to house a dedicated National Commission for the Scheduled Tribes. This bifurcation came into effect on 19 February 2004, giving Scheduled Tribes their own exclusive constitutional commission for the first time.

A later change, the Constitution (One Hundred and Second Amendment) Act, 2018, tidied up the surrounding provisions further by removing references to "other backward classes" from this cluster of articles, once the National Commission for Backward Classes was itself granted separate constitutional status under a new Article 338B.

Composition of the NCST

Article 338A(1) establishes the Commission and names it the National Commission for the Scheduled Tribes. Structurally, it mirrors the pattern used for its Scheduled Caste counterpart: the NCST is a multi-member body consisting of a Chairperson and four other Members, all appointed by the President.

Feature National Commission for Scheduled Tribes
Constitutional basis Article 338A
Inserted by 89th Constitutional Amendment, 2003 (effective 19-2-2004)
Composition Chairperson + four Members
Mode of appointment By the President, by warrant under hand and seal
Nature Constitutional body (not statutory)
Power to frame own rules Yes — the Commission regulates its own procedure

Functions and Duties

The functional framework built into Article 338 for the Scheduled Castes Commission — investigation of safeguards, inquiry into complaints, evaluation of their working, and periodic reporting — was carried over in substance to Article 338A for Scheduled Tribes, since the two provisions were carved out of what was originally a single article. In outline, the Commission's duties cover:

  • Investigating and monitoring matters relating to the constitutional and legal safeguards available to Scheduled Tribes, and evaluating how effectively those safeguards are working in practice.
  • Inquiring into specific complaints concerning the deprivation of the rights and safeguards of Scheduled Tribes.
  • Advising on and participating in the planning of measures for the socio-economic development of Scheduled Tribes, and assessing the progress of that development.
  • Reporting to the President, and making recommendations for the more effective implementation of safeguards and for further measures needed for the protection, welfare, and advancement of Scheduled Tribes.

Crucially, the Constitution also imposes a consultation obligation on government: the Union and every State Government must consult the Commission on all major policy matters affecting Scheduled Tribes. This gives the NCST a formal advisory role that goes well beyond after-the-fact grievance redressal — it is meant to be consulted before policy affecting Scheduled Tribes is finalised.

Investigative Powers

While investigating any matter relating to safeguards, or while inquiring into a specific complaint, the Commission is vested with all the powers of a civil court trying a suit. These include the power to:

  • Summon and enforce the attendance of any person from any part of India and examine that person on oath.
  • Require the discovery and production of any document.
  • Receive evidence on affidavit.
  • Requisition any public record or copy of it from any court or office.
  • Issue commissions for the examination of witnesses and documents.

These quasi-judicial powers allow the Commission to conduct meaningful investigations rather than merely receive and forward complaints.

Relationship with the Other Constitutional Commissions

Article 338A did not emerge in isolation — it belongs to a small family of constitutional commissions created for specific social groups, each carved out through amendment over time.

Article Commission Constituency Established/Inserted
338 National Commission for Scheduled Castes Scheduled Castes Restructured 1990 (65th Amdt.); Scheduled Tribes hived off 2003
338A National Commission for Scheduled Tribes Scheduled Tribes Inserted by 89th Amendment, 2003
338B National Commission for Backward Classes Socially and educationally backward classes Given constitutional status later, on the same pattern

Each of these three commissions follows a broadly similar constitutional design: a Chairperson and Members appointed by the President, the power to regulate its own procedure, civil-court powers of investigation, a duty to report to the President, and a corresponding obligation on governments to consult it on major policy matters affecting the group concerned.

Why the NCST Matters

The NCST's oversight sits alongside a wider set of constitutional affirmative-action provisions for Scheduled Tribes — reservation of seats in the Lok Sabha and State Legislative Assemblies under Articles 330 and 332, and special provisions enabling reservation in education and public employment. Because these protections span multiple articles and multiple layers of government, an independent constitutional body with the power to investigate, summon evidence, and demand consultation gives Scheduled Tribes an institutional channel to ensure that safeguards already written into the Constitution are actually implemented, not merely declared.
