The Constitution sets out the principles of India’s elections in just six articles (324–329) and leaves the machinery to Parliament. Two laws carry that machinery: the Representation of the People Act, 1950 (who votes, where, and how many seats) and the Representation of the People Act, 1951 (who can be elected, how elections are conducted, and how they are challenged). “Salient features of the Representation of People’s Act” is one of the few statutes named in the Mains GS II syllabus.

What UPSC asks

Prelims: which Act covers what, Section 8 disqualifications, Sections 29A and 123, election petitions, NOTA, the two-constituency rule, delimitation freezes, and the 61st Amendment (voting age 18).
Mains GS II: criminalisation of politics, election finance after the electoral bonds judgment, EVM and VVPAT debates, simultaneous elections, the Model Code of Conduct, and the role of courts in electoral reform.
