Public interest litigation secures access to justice and representation for groups to protect collective legal rights. Public Interest Litigation is a procedural mechanism for enforcement of matters affecting the public or a class of the community where their legal rights or liabilities are implicated, aimed at vindicating interests beyond private curiosities. It provides legal representation to previously unrepresented groups and functions as a collaborative instrument involving petitioners, public authorities and the judiciary to secure observance of constitutional or basic human rights and protections for vulnerable sections of society.
