Key legal issues
#Whether Githongo SPMC E & L Case No. E002 of 2024 was res judicata in light of Meru High Court Succession Cause No. 1 of 1994
Yes. The succession cause involved the same suit lands and parties, and the High Court determined to whom the late Samuel's share was to devolve and in what capacity; the fresh suit contesting that devolution, merely rephrased as customary trust, was res judicata.
The two suit lands were part of the estate of the late Ithiria distributed by the High Court. The dispute in the succession cause concerned devolution of the late Samuel's entitlement and the capacity in which it would be held. The High Court determined these questions, holding the late Samuel had gifted his entitlement to the 1st and 2nd respondents. The customary trust claim in the magistrate's court directly contested the same devolution; all elements of res judicata under Section 7 of the Civil Procedure Act were present. The proper avenue was an appeal to the Court of Appeal, which was already pending.
Whether the succession court had jurisdiction to determine the trust/devolution issues such that res judicata could be sustained
Yes. The High Court had jurisdiction over gifting, devolution of a deceased's entitlement and the capacity in which devolved property was to be held under the Law of Succession Act.
The court found that the issues of gifting and devolution fell squarely within the Law of Succession Act framework, and the High Court was properly seized of the dispute. The devolution was absolute, without trustship. Any challenge to that devolution lay in the Court of Appeal, not a fresh land suit before a Senior Principal Magistrate's Court.
Legal principles established
#- A party alleging res judicata must demonstrate a previous suit on the same cause of action in a competent court, a previous determination of the same issue, and privity of parties.
- The elements of res judicata are conjunctive rather than disjunctive.
- A party aggrieved by succession devolution orders must contest them on appeal, not by filing a fresh suit rephrased as a customary trust claim.
