What is a Social Interest Litigation or Public Interest Litigation? Do they both refer to same with reference to law as a subject?

Public Interest Litigation or PIL, in Indian context is a right given to every citizen, under Article 32 of the Indian Constitution. Public Interest Litigation means that, it is not necessary for the aggrieved party to represent itself in fornt of the Court, but the Court itself (suo moto) introduces the case on behalf of the aggrieved party. In India PIL is governed under PART III of the Constitution i.e. Fundamental Rights.

The litigation whereas the interest of the society is protected by the courts and can be initiated by any NGO's or any person who doesn't pursue his personal interest rather to upheld or protect the interest of society is called Social Interest Litigation. Public Interest Litigation is also the same as Social Interest Litigation and in India, it is Public interest litigation which is adopted from USA's Social Interest Litigation and is in the same sense and meaning of protecting the interest of larger masses or public at large. so they are same. My 2 cents. Thanks.

means litigation for the protection of public interest. It is litigation introduced in a court of law, not by the aggrieved party but by the court itself or by any other private party. It is not necessary, for the exercise of the court's jurisdiction,
