The petitioner, Jagdish Singh, challenged the reservation of the Kadipur Assembly Constituency for Scheduled Castes, arguing it was discriminatory and violative of the Fundamental Right to Equality. The petitioner claimed that the Delimitation Act, 2002, and the reservation of seats for Scheduled Castes and Scheduled Tribes were being misinterpreted, resulting in stagnation in reservation of seats. The Election Commission of India objected to the maintainability of the writ petition, citing Article 329(a) of the Constitution, which prohibits challenges to the validity of laws relating to delimitation of constituencies.
