What this practically means
#Executive summary
#Key legal issues
#Whether res judicata bars the Petition
Yes; the issues in the Petition were directly and substantially in issue in the prior Voi ELC Case No. 12 of 2019 and its appeal ELCA No. 22 of 2023, which were decided on merit between essentially similar parties.
The Court set out the elements of res judicata under section 7 of the Civil Procedure Act: a former final judgment on merit by a competent court with identical parties, subject matter and cause of action. It found the parties essentially similar, the same suit parcel, and a judgment on merit, Justice Matheka having dismissed the appeal and upheld the respondent's acquisition and title. Even issues framed as constitutional rights are barred. The Petitioner did not seek to annul the subsequent proceedings, so is bound by them.
