Supreme Court of Justice

Supreme Court of Justice of Papua New Guinea

Reviewed· 2026-08-03Waigani, Port Moresby

The final court and the only court that may authoritatively interpret the Constitution. Section 18 gives it original and exclusive jurisdiction over constitutional interpretation, and section 19 lets designated authorities — including Parliament, the Head of State and provincial governments — seek an opinion that binds, which is unusual: most final courts refuse advisory work. It has used section 57 to order remedies for basic-rights breaches on its own initiative.
