How do Articles 19 and 29 relate to Article 15, according to Article 15(5)?
According to Article 15(5), nothing in Article 19 (which deals with protection of certain rights regarding freedom of speech, etc.) and Article 29 (which deals with protection of interests of minorities) shall prevent the State from making special provisions by law for the advancement of any socially and educationally backward classes of citizens or for the Scheduled Castes or the Scheduled Tribes in so far as such special provisions relate to their admission to educational institutions, including private educational institutions whether aided or unaided by the State, other than the minority educational institutions referred to in Article 30.

Article 15(5) allows the State to make special provisions for the advancement of socially and educationally backward classes and Scheduled Castes/Tribes in the context of their admission to educational institutions, which is also covered by Articles 19 and 29. This means that Article 15(5) works together with Articles 19 and 29 to ensure that the State can make special provisions for these disadvantaged groups in various areas, including education.
