Every state has a central structure that consists of three main parts that are the legislature, executive, and judiciary. These institutions are specialized in performing specific functions provided under the constitution like rule-making, rule application, and adjudication with a great deal of precision and caution. In India, no institutions are allowed to perform the duty of others, as our constitution provides a theory of separation of powers. The Supreme Court of India enjoys very wide power under the constitution and performs various functions. The main function is to review the legislative and executive actions of the state that should not violate the fundamental principles enshrined under the constitution.
