INTACH founder members realized the need for the support of heritage friendly rules and regulations in preserving India’s heritage. This led to the setting up of Heritage Legislation Cell which began its work as early as 1984-85 and was actively involved in highlighting the legal aspects of heritage conservation.

Over the years INTACH as a national entity continued to file petitions and initiate PILs to protect t heritage in jeopardy. Some of its most signal victories are:
