Executive summary

#
This was a first appeal to the Environment and Land Court at Thika against the judgment of Trial Magistrate M.W. Kurumbu delivered on 23rd February 2023. The dispute arose from two sale agreements dated 27/08/2008 and 05/05/2012 over the parcel known as MITUBIRI/NANGA BLOCK 1/184, sold at Kshs 800,000, of which the Respondent paid Kshs 450,000. The trial court directed the Appellant to excise one acre and transfer it to the Respondent within 90 days and to refund Kshs 194,000, dismissing the Appellant's counter-claim in trespass, and directing each party to bear their respective costs. The Appellant raised five grounds, principally that the trial court rewrote the parties' contracts and rewarded the Respondent despite finding him in breach. The Respondent urged that the trial court properly analysed the evidence and applied contract law principles. Mogeni J restated the first appellate court's duty to re-evaluate the evidence, applied Mbogo v Shah on interference with discretion, and held that although courts must not rewrite contracts, the trial court was entitled to enforce the parties' own second agreement in the interest of substantive justice under Article 159(2)(d). The Court applied the doctrine of unjust enrichment, following Chase International Investment Corporation and Willy Kimutai Kitilit, holding that the Appellant could not retain both the land and the money paid. The trespass counter-claim failed as the Respondent's possession rested on the agreements. The appeal was dismissed with no order as to costs on 3rd April 2025.

Key legal issues

#
01

Whether the trial court rewrote the parties' contracts

Holding

The trial Magistrate did not err; she enforced the second agreement of 5/05/2012 which the parties had mutually agreed, in the interest of substantive justice

Reasoning

The Court held that although courts should not rewrite contracts, the trial court was entitled to enforce the second agreement the parties themselves entered into, under Article 159(2)(d). The Respondent had pleaded a prayer for further or other relief as the court deemed just, and it would be unjust to dismiss his claim where he took possession, developed the property and paid over half the purchase price.

p. 5
02

Whether the doctrine of unjust enrichment justified the refund and excision orders

Holding

Yes - the Appellant would be unjustly enriched by retaining both the land and the Kshs 450,000 paid

Reasoning

The Court applied the doctrine of unjust enrichment and the restitutionary remedy, citing Chase International Investment Corporation, holding that to allow the Appellant to keep both the suit land and the monies paid would offend conscience and equity. The basic elements of enrichment at the plaintiff's expense and injustice of retention were satisfied on the facts.

p. 5
03

Whether the counter-claim in trespass was rightly dismissed

Holding

Yes - the evidence did not support the claim for trespass, as the Respondent's possession was pursuant to the sale agreements

Reasoning

The Respondent took possession immediately upon execution of the first sale agreement as permitted by its terms. Since his presence on the suit property rested on a subsisting contractual basis that the trial court enforced, the Appellant's claim that he was a trespasser, founded on her purported rescission, could not stand. The appellate court found no error in the dismissal of the counter-claim.

p. 4
04

The scope of the first appellate court's mandate

Holding

The first appellate court must re-evaluate, re-assess and re-analyse the record while making due allowance for not having seen or heard the witnesses

Reasoning

Guided by Abok James Odera & Associates v John Patrick Machira, the Court restated that on a first appeal it must reconsider the evidence and reach its own conclusions, but must not introduce extraneous matters not dealt with by the parties, and must give allowance for not having heard the witnesses firsthand.

Legal principles established

#
  • It is not the business of the Court to rewrite the terms of a contract, but the Court has a duty to render substantive justice under Article 159(2)(d) of the Constitution
  • A claim may properly be founded for restitution where it would be unjust to allow a party to retain the benefits of an unjust enrichment
  • Elements of unjust enrichment: the Defendant enriched by receipt of a benefit, at the Plaintiff's expense, and it would be unjust to allow retention
  • An appellate court may interfere with the trial court's exercise of discretion only if satisfied the trial court misdirected itself, arrived at a wrong decision resulting in injustice

Court orders

#
  1. 1.The appeal is dismissed
  2. 2.No order as to costs
  3. 3.Orders accordingly (the trial court's judgment of 23/02/2023 directing excision of 1 acre and refund of Kesh 194,000 stands)
