The bottom line
#Kenya's Court of Appeal confirmed that you cannot use a constitutional petition to dodge a finalized land decree—execution disputes must go to the executing court.

#Key legal issues
#Whether a constitutional petition challenging execution of a decree is an abuse of process
Yes. Where the substance of a claim is an execution question, section 34 of the Civil Procedure Act requires it to be raised before the executing court; a constitutional petition raising the same questions is a collateral attack on a finalized decree and an abuse of process.
The Court characterized the appellants' grievance as a classic execution question arising from the 1986 decree in the 1973 suit. Section 34(1) of the Civil Procedure Act mandates that all questions relating to execution, discharge or satisfaction of a decree be determined by the executing court and not by separate suit. Allowing parties to relitigate execution issues through fresh constitutional petitions would undermine the finality of judgments, invite endless litigation, and destabilize the administration of justice. The High Court's inherent jurisdiction to prevent misuse of its processes justified striking out the petition.
Applicable appellate standard of review
The abuse-of-discretion standard from Mbogo & Another v Shah applies: the appellate court does not substitute its own view but asks whether the judge exercised discretion on proper principles.
Because the decision under appeal involved the exercise of judicial discretion in determining whether the petition was an abuse of process, the Court applied the Mbogo v Shah standard. It declined to interfere absent a misdirection or manifest wrongness in the exercise of discretion. Applying that standard, the Court found the Judge correctly characterized the petition as a collateral attack and correctly held it an abuse of process, and therefore found no basis to interfere.
Finality of litigation and inherent power to prevent abuse of process
Courts possess inherent jurisdiction to prevent misuse of their processes, exercised to prevent proceedings being used as instruments of delay, harassment or obstruction.
Relying on Muchanga Investments Ltd v Safaris Unlimited (Africa) Ltd, the Court reaffirmed that abuse of court process includes use of judicial proceedings in an oppressive, vexatious or obstructive manner. The five-decade history of litigation over the suit property demonstrated repeated attempts to reopen matters already decided, entitling the High Court to intervene to prevent further abuse.
