Legal Commentary & Landmark Judgments: Section 3
Section 3 empowers the State Government to exempt any race, sect, or indigenous tribe from the operation of the Act or specific parts thereof by notification in the Official Gazette.
When litigating succession rights involving tribal or notified indigenous families in northeastern states, Jharkhand, or Odisha, counsel must verify whether a Section 3 exemption notification covers the tribe, which displaces the Act in favor of uncodified customary law.
