29. Protection of interests of minorities. (1) Any section of the citizens residing in the territory of India or any part thereof having a distinct language, script or culture of its own shall have the right to conserve the same. (2) No citizen shall be denied admission into any educational institution maintained by the State or receiving aid out of State funds on grounds only of religion, race, caste, language or any of them.
Why are "sex" and "place of birth" omitted in some of the clauses? Article 15 explicitly mentions "sex" and "place of birth" which is missing in article 29. When I go through many of the articles I see "sex" is explicitly mentioned but not here.
