A government resolution first, an Act afterwards: how SEBI became a statutory body
Background
The Securities and Exchange Board of India (SEBI) did not begin with a law of its own. SEBI was constituted as a non-statutory body on April 12, 1988 through a resolution of the Government of India. It was established as a statutory body in the year 1992, and the provisions of the Securities and Exchange Board of India Act, 1992 (15 of 1992) came into force on January 30, 1992. The preamble of SEBI describes its basic functions as protecting the interests of investors in securities and promoting the development of, and regulating, the securities market. SEBI also lists the Securities Appellate Tribunal (SAT) among the institutions in its own structure.
