The Supreme Court of India has laid down guidelines regarding the types of cases that are ordinarily not entertained as Public Interest Litigation. These typically include cases that relate to personal or private disputes, service matters concerning individuals, and matters related to procedural issues of individual cases in lower courts. PIL is intended to address issues of broader public importance, violation of fundamental rights of a collective group, or matters where justice is denied to underprivileged sections of society who cannot approach the court themselves.
