Public Interest Litigation (PIL) is a legal mechanism that allows individuals or groups to seek justice for issues affecting the public at large, even if they are not directly affected. It was introduced in India to promote social justice and ensure the protection of fundamental rights. The Supreme Court and High Courts entertain PILs under Article 32 and Article 226 of the Constitution, respectively. PILs have played a crucial role in addressing issues like environmental protection, human rights violations, and corruption. However, the misuse of PILs for personal or political gains has raised concerns about judicial overreach and frivolous litigation.
