The Communal G.O. case
State of Madras v. Champakam Dorairajan
Held. The Madras Government reserved seats in medical and engineering colleges by caste and religion through a Communal Government Order. The Court struck it down under Article 29(2), holding that the Directive Principles cannot override fundamental rights.
Why it matters. Parliament answered with Article 15(4), inserted by the First Amendment, which allows special provisions for socially and educationally backward classes.
