Wambui v Republic

Wambui v Republic (Petition E007 of 2025) [2026] KEHC 12304 (KLR) (Constitutional and Human Rights) (3 August 2026) (Judgment)

Court

High Court

Case number

Petition E007 of 2025

Judge

["RE Aburili"]

The High Court lacked jurisdiction to reopen or alter a sentence already challenged on appeal and affirmed by the Court of Appeal. The petition repackaged sentencing complaints as constitutional grievances, but the Court was functus officio and could not supervise a superior court or invalidate a commutation made under Article 133. The commutation of the death sentence to life imprisonment was lawful, and no unconstitutionality was shown.

Court

High Court

Case number

Criminal Miscellaneous Application E060 of 2025

Judge

["RN Nyakundi"]

The application was a disguised appeal seeking to reopen conviction and sentence issues that had already been fully determined by the trial court and on appeal. Because the applicant had exhausted the appellate process and the issues were barred by res judicata and estoppel, the High Court lacked jurisdiction to entertain the resentencing request. The motion was therefore dismissed.
