PIL in Indian Law: Definition, Scope, and Exam Importance
PIL Full Form refers to "Public Interest Litigation." This term is widely used in the Indian legal system and judiciary. A PIL is a legal process or petition filed in court by an individual or group, seeking judicial intervention for matters impacting the public at large rather than just personal interests. It is an important tool that allows people to raise issues like human rights, environmental protection, and broader social concerns before the courts. Understanding the full form and concept of PIL is vital for students appearing in legal, civil service, and general knowledge exams.
What is Public Interest Litigation (PIL)?
Public Interest Litigation is a special type of legal action. Unlike typical litigation, where only affected parties can approach the court, a PIL enables any citizen, NGO, or group to file a petition when the interests of the general public are at stake. These litigations address issues like pollution, safety hazards, or protection of rights for marginalized groups. The goal is to ensure justice and legal remedies for problems affecting society as a whole, such as environmental concerns or violation of fundamental rights.
