Why is the judiciary necessary in democracy?

To protect rights and maintain rule of law

The governing concept is the rule of law in a constitutional democracy. The judiciary independently interprets the Constitution and laws, settles disputes and reviews whether government action is lawful. It can protect citizens when authorities violate rights and can require public institutions to follow constitutional limits. Option A is correct because protecting rights and maintaining the rule of law are essential judicial functions. Option B is wrong because courts do not exist to stop elections. Option C is wrong because the judiciary is a separate organ and does not abolish Parliament. Option D contradicts impartial justice, since judges must decide according to law rather than provide private benefits to ministers.
