The judiciary acts as the most important institutional check on executive excesses in a constitutional democracy.
Through judicial review, courts examine the constitutionality and legality of executive actions.

In India, this role is exercised by the Supreme Court and High Courts under Articles 32, 136, 226, and 227 of the Constitution.
