The guardian of Fundamental Rights enumerated in the Indian Constitution is the Supreme Court. The Supreme Court plays a vital role in upholding and protecting the fundamental rights of the citizens. It serves as the guardian by interpreting and enforcing these rights. The Supreme Court has the power to declare any law or government action that violates the fundamental rights as unconstitutional and void. It acts as a check on the legislative and executive branches of the government to ensure that they do not infringe upon the fundamental rights of the citizens. The Parliament, Constitution, and President do not directly serve as the guardian of the fundamental rights, although they do play significant roles in the functioning and protection of these rights.
