Executive summary

#
This ruling by the Environment and Land Court at Nairobi (C.K. Nzili, J) addresses whether the court, having delivered final judgment on 11 May 2023 in favour of the Plaintiff (Stephen Njoroge) against the National Social Security Fund Board of Trustees, retains jurisdiction to substantively re-adjudicate the parties' disputed financial accounts. The 2023 judgment directed the Defendant to furnish true and accurate statements of account for Hazina-B30/F1 and L.R. No. Kitusuru 101/C233. Subsequent proceedings included a Bill of Costs ruling, struck-out applications, and orders of 29 May 2025 directing execution of transfer documents and requiring the parties to agree on the statements of account. Repeated attempts at agreement failed, and only the Respondent filed submissions on the points of divergence. The court held that the doctrine of functus officio, founded on finality of litigation, bars merit-based re-engagement after final judgment, but does not preclude proceedings incidental to or consequential upon the final decision. Since the judgment itself ordered accounts to be furnished, the taking of accounts is a consequential step, not a reopening of the dispute. Relying on Order 21 Rule 17 of the Civil Procedure Rules, the court held it retains a limited supervisory jurisdiction over the taking of accounts. It ruled that it is functus officio as to determination of the parties' statement of accounts, directed the parties to comply with the existing judgment and decree, and referred the disputed accounts to the Deputy Registrar for taking, examination and reconciliation. No costs order was made.

01

Whether the court, having delivered final judgment, may substantively re-adjudicate the parties' disputed accounts

Holding

No - the court is functus officio as to merits-based determination of the accounts, but retains supervisory jurisdiction to refer the accounts to the Deputy Registrar for taking, examination and reconciliation

Reasoning

The doctrine of functus officio rests on finality of litigation: after final judgment and decree the court cannot re-engage with the merits. However, proceedings incidental to or consequential upon the final decision remain within its jurisdiction. The judgment expressly directed the Defendant to furnish true and accurate statements of account, so taking of accounts is a consequential step giving effect to an existing order, not a new cause of action. Order 21 Rule 17 permits special directions and referral of accounts; the Deputy Registrar may ascertain outstanding balances to found execution.
