Kamuru v Lingine (Environment and Land Case E017 of 2026) [2026] KEELC 3099 (KLR)
The bottom line
#A Kenyan landowner lost his injunction and had his entire suit struck out because his affidavits were improperly commissioned and he ran two cases over the same dispute.
What this practically means
#Executive summary
#Key legal issues
#Competency of affidavits commissioned by a firm of advocates
The supporting and verifying affidavits were incompetent and invalid because the stamp of the law firm, not that of a designated commissioner for oaths, was affixed to the jurat
Sections 4 and 5 of the Oaths and Statutory Declaration Act vest the power to administer oaths in a commissioner for oaths personally, and Section 3 requires the commissioner to sign the roll. That authority cannot be delegated to a law firm. An affidavit bearing a firm's stamp rather than a designated commissioner's stamp is defective, and even the verifying affidavit suffers the same defect.
Whether the suit disclosed a reasonable cause of action
The suit did not disclose a reasonable cause of action because it sought to impeach, through an ordinary suit, lawful orders of the magistrate's court which remain in existence and unvaried
The lower court's orders of 08.05.2025 underpinning the alteration of the registry index map had not been set aside or varied. A court exercising appellate jurisdiction may set aside subordinate court decisions only via appeal or suitable judicial review, not a fresh suit. Using a separate suit to supersede such orders amounts to approaching the court through the back door.
Whether the suit and application were an abuse of due process
They were an abuse of the due process of the court because the applicant simultaneously pursued a review application before the lower court seeking the same or near-same orders
The applicant had filed a review application dated 02.04.2026 in the lower court that remained undetermined and sought substantially the same relief as this suit. Settled law prohibits a multiplicity of suits over the same subject matter; where court processes are being misused, the court must stand firm and protect the integrity of the judicial process.
Legal principles established
#- Only a designated commissioner for oaths, and not a firm of advocates, may administer oaths and commission affidavits; a defective jurat renders an affidavit incompetent
- Defects in commissioning affidavits are substantive and fundamental and cannot be cured under Article 159(2)(d) of the Constitution
- Orders of a subordinate court cannot be set aside or varied through a separate suit; they must be challenged by way of appeal or suitable judicial review/review application
- A party cannot prosecute parallel proceedings in different courts over the same matter; multiplicity of suits is an abuse of court process
Court orders
#- 1.The Application dated 17.04.2026 be and is hereby struck out
