The Supreme Court (Arts 127–137): the apex court — court of record, final interpreter of theConstitution and law, chief of judicial administration, its interpretations and legal principles binding on all (Art 128 — the precedent's constitutional source, applied through Art 128's discipline); the Chief Justice and up to twenty justices (Art 129).
1.5.1 Ordinary Jurisdiction
(a) Hearing the Appeal — appeals from High Court judgments and orders as law provides; PIL and interpretation questions; references from HCs (Art 133's clauses). (b) CorrectionalJurisdiction — the Court's power to correct errors and to manage causes: transfer and invitation of cases of public importance, inter-HC transfers for impartiality (Art 134), correction of its own ongoing/interlocutory orders (the chalu-aadesh correction practice) and the judicial-administration directives (Art 128). (c) Review — the Court's power to review its own decisions (Art 133's jurisdiction list; the review heard by a different bench), on the classic grounds: error apparent, new matters, the interest of justice — rare, corrective, not a second appeal. (d) Revision — the supervisory power to correct subordinate courts' errors of law apparent where no appeal lies (the justice-administration legislation and the Court's rules) — legality's patrol, not merits' re-trial.
1.5.2 Extra-Ordinary Jurisdiction (Hearing of Writ Petitions)
The writ jurisdiction — Art 133: (1) any Nepali citizen may petition to declare a law void (an unreasonably-restrictive or otherwise inconsistent law — including provincial-local conflicts with the federal order); (2) the extraordinary power for FR enforcement, for legal rights withoutother effective remedy, and for public-interest constitutional/legal questions (the PIL root); (3) the five writs: habeas corpus (produce the detained — liberty's writ), mandamus (perform the public duty), certiorari (quash the excess of jurisdiction/legal error on the face), prohibition (stop the impending excess), quo warranto (by what authority does the office-holder hold office). The High Court's parallel writ power within the province — Art 144. The writs are discretionary, forged for justice: the Court may issue "any other appropriate order" to do complete justice.
