ALI MUZAFFAR vs Mst. AMTUL BEGUM and 3 others

This matter comes before the Supreme Court of Pakistan through a petition for special leave to appeal against the concurrent findings of the trial court, the Additional District Judge, and the High Court, which held that the decision in an earlier writ petition brought by the petitioner operated as res judicata. The core legal question is whether a prior judgment rendered in a writ petition filed by the same petitioner constitutes res judicata to bar subsequent proceedings. The Supreme Court dismissed the petition, holding that the lower courts' finding on res judicata was free from any legal infirmity. The key principle laid down is that a prior judicial decision involving the same parties and subject matter, particularly from a writ petition previously instituted by the same litigant, effectively operates as res judicata to preclude subsequent agitation of the same issues.
