Priscilla Wangui Mukundi & 10 Others v Kenya Prisons Service, Commissioner General of Prisons & Attorney General; Public Service Commission (Interested Party)
The bottom line
#Kenya's Employment Court dismissed 11 Prisons officers' claims to higher rank and Kshs. 26.4 million in arrears because their appointments lacked required Public Service Commission approval.
What this practically means
#Executive summary
#Key legal issues
#Whether the petitioners' designation as Commissioners of Prisons was validly effected
No. The alleged harmonisation signal of 10 June 2024 was not backed by written approval, and the circular of 5 June 2024 harmonised grading structures without automatically promoting officers.
The court found the signal filed related to different matters of 25 February 2025, well after the alleged date. The PSC's 5 June 2024 circular merely harmonised the Prisons grading structure with the National Police Service and National Youth Service. Promotion and revision of terms require the PSC's written approval under Article 234; absent that, the claimed designation and benefits were not legally due.
Whether the respondents violated the petitioners' constitutional rights through demotion and non-payment
No. The claim was premised on rights not accrued from an illegality, and the arrears claim was unparticularised.
Since the initial appointment as Assistant Commissioners was issued without requisite PSC approval and was ultra vires, no legitimate expectation or accrued rights could arise. The Kshs. 26,433,000 claim was not disaggregated per petitioner as required by Rule 23 of the ELRC (Procedure) Rules, so a general claim could not suffice.
Whether the petitioners were discriminated against
No. The comparator could not apply and no CBA at shop floor level was demonstrated.
The discrimination claim rested on rights as Commissioner of Prisons which never accrued. The payment statements filed did not reflect unionisation or an active CBA at the shop floor to support agency fees, so the alleged selective treatment of officers recruited alongside them had no foundation.
Whether certiorari, prohibition and mandamus should issue
No. The orders sought could not issue as framed and the petition was dismissed.
Having found no accrued rights, no valid designation as Commissioners of Prisons, and an unparticularised arrears claim, the court held the orders could not issue as framed. Legitimate salary arrears, where due, should be assessed and paid administratively without a constitutional petition.
