(e) Any other order that the Honourable Court deems fit to give in the interest of justice. (f) That, further grounds shall be adduced in the sworn supporting affidavit of Joseph Maina Mwangi among other grounds to be adduced during the hearing of this application. 2. The application is based on the grounds thereto which states: (a) That I was charged and convicted for the offence of robbery with violence contrary to Section 296(2) of the Penal Code in Criminal case No.950 of 2003 at Murang’a Law Court and sentenced to suffer death.

The application is also based on the affidavit sworn by the applicant/petitioner dated 25th July 2023 which reiterates the grounds thereto. 4. I have heard both parties in the application thro’ ORI address as indicated on the record. Notably the following facts are not in dispute. (a) The applicant was given a lawful death sentence in the Chief Magistrate’s Court. (b) The applicant exercised his right of appeal before the High Court. In that regard, the jurisdiction of the High Court was spent. (c) The matter went to the Court of Appeal, consequently it cannot be heard again by the High Court after it has been heard by the Court of Appeal. (d) The case of Muruatetu relate to murder cases only and this is a case of robbery with violence. (e) The sentence herein is not death anymore, as such Muruatetu becomes untenable. HCCHR PET E007 OF 2024 JUDGMENT Page 4 of 5 In conclusion, I find that this court is junctus officio as review of sentence herein is concerned. Further, the matter herein though stated to be a Petition, does not have any Petition filed. In that case, the notice of motion application herein is dismissed/struck out due to want of jurisdiction. It is so ordered. GRACE L. NZIOKA JUDGE 28/4/2026 HCCHR PET E007 OF 2024 JUDGMENT Page 5 of 5
