Introduction
Article 366(25) states that Scheduled Tribes means such tribes or tribal communities or parts of or groups within such tribes or tribal communities as are deemed under Article 342 to be Scheduled Tribes for the purposes of the Constitution.
This means Article 366(25) itself does not independently list or identify any tribe. It only tells us that the tribes recognized as Scheduled Tribes are those that are specified under Article 342.
So, Article 366(25) must always be read together with Article 342.
Link with Article 342
Article 342 provides the actual constitutional mechanism for specifying Scheduled Tribes.
Under Article 342:
• The President may specify tribes or tribal communities as Scheduled Tribes for a State or Union Territory
• This is done by public notification
• Parliament can later include or exclude any tribe from the list
• Neither the President nor State governments can unilaterally alter the list after notification, except through Parliament
Thus:
• Article 366(25) gives the definition
• Article 342 gives the procedure and authority
Nature of Definition
The definition under Article 366(25) is:
• Constitutional
• Indirect
• Dependent on Presidential notification under Article 342
• State-specific in application
This is very important because a community may be recognized as a Scheduled Tribe in one State but not necessarily in another.
Why this provision is important
Article 366(25) is significant because it forms the base for applying many constitutional protections and welfare provisions for Scheduled Tribes.
It is relevant for:
• Reservation in education and public employment under Articles 15(4), 15(5), and 16(4)
• Political reservation under Articles 330 and 332
• Claims relating to tribal welfare and administration under the Fifth Schedule and Sixth Schedule
• Directive Principles such as Article 46
• Commissions and safeguards under Article 338A

State-specific character
One of the most important features of Scheduled Tribe recognition is that it is linked to a particular State or Union Territory.
This means:
• A person belonging to a Scheduled Tribe in one State may not automatically get the same recognition in another State
• Benefits are usually tied to the notified area and list
• This avoids automatic nationwide extension of status without constitutional process
Judicial Interpretation and Case Laws
Marri Chandra Shekhar Rao v Dean, Seth G S Medical College
The Supreme Court held that Scheduled Caste or Scheduled Tribe status is State-specific. A person recognized in one State cannot automatically claim the same status in another State unless that community is also notified there.
Importance:
• Clarified territorial nature of ST recognition
• Reinforced Article 342 framework
Action Committee on Issue of Caste Certificate v Union of India
The Supreme Court reaffirmed that SC and ST recognition is State-specific and benefits cannot automatically travel from one State to another.
State of Maharashtra v Milind
The Supreme Court held that courts cannot modify or expand the Presidential list of Scheduled Tribes. Only Parliament has the power to include or exclude communities from the list.
Importance:
• Presidential list is final
• No evidence-based judicial addition allowed
• Article 342 must be strictly followed
No independent judicial addition
Courts cannot declare any community as Scheduled Tribe merely because it resembles another tribe or because of social backwardness. Recognition must come strictly through the constitutional route under Article 342.
This is one of the most important legal principles connected to Article 366(25).
Criteria in practice
The Constitution itself does not list detailed criteria for Scheduled Tribe identification in Article 366(25). Historically, factors like:
• Distinct culture
• Geographical isolation
• Tribal characteristics
• Economic and social backwardness
have influenced identification, but legally the final authority remains the constitutional notification process under Article 342.
Importance for governance
Article 366(25) is foundational for tribal policy in India because it determines who can claim:
• Reservation benefits
• Political representation
• Special welfare schemes
• Constitutional protections for tribal areas
• Safeguards against exploitation and displacement
Conclusion
Article 366(25) provides the constitutional definition of Scheduled Tribes by linking the term directly to Article 342. Its importance lies in giving legal certainty to tribal recognition and serving as the basis for a wide range of constitutional safeguards, reservations, and welfare measures.
