This document discusses laws that are inconsistent with fundamental rights in India. It states that Article 13 declares that any laws, including permanent laws passed by Parliament or state legislatures, ordinances, delegated legislation, customs, or non-legislative sources that violate fundamental rights will be void. This confers the power of judicial review on the Supreme Court and high courts to declare laws unconstitutional. While a constitutional amendment is not considered a law, the Supreme Court ruled that even amendments can be challenged if they violate parts of the basic structure of the constitution.
