Ngayu v Unilever Tea Kenya Ltd
The bottom line
#Kenya's Court of Appeal confirmed that a signed settlement voucher ends an employment dispute unless you can prove fraud, duress, or misrepresentation.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether new issues (duress, lack of bargaining power, Section 119 Evidence Act presumptions) not pleaded or argued at trial may be raised on appeal
- 2.Whether an employee who is paid terminal dues and executes a discharge voucher in full and final settlement can subsequently sue the same employer citing further claims arising from the same employment relationship
Key legal issues
#Whether new grounds of duress and unequal bargaining power could be raised for the first time on appeal
No. The appellant never pleaded or testified to duress before the trial court; a party is strictly bound by their pleadings and cannot re-engineer their case on appeal.
The court reviewed the appellant's statement of claim, witness statement and evidence and found no mention of duress or bargaining power. Citing Osede, GRD v Republic and Wareham, it held that an appellate court cannot usurp the trial court's function by evaluating brand-new arguments, since the other party had no fair notice and it would litigate a different case from the one decided.
Whether a discharge voucher in full and final settlement bars subsequent claims arising from the same employment relationship
Yes. A voluntarily executed discharge voucher is a valid, binding contract; the employee is estopped from further claims unless duress, fraud, misrepresentation or ambiguity is strictly proved.
The court applied pacta sunt servanda and the public policy of finality in disputes, relying on Gbenga-Oluwatoye (Constitutional Court of South Africa) that full and final settlement waivers are valid and consistent with public policy. The recognized exceptions are proven duress, fraud/misrepresentation, and ambiguous text construed contra proferentem; none was pleaded or established here.
Legal principles established
#- An appellate court will not entertain new issues, grounds or claims that were not raised, argued and determined by the trial court.
- A duly executed discharge voucher constitutes a valid, binding contract that extinguishes all existing and future statutory and contractual claims unless a vitiating factor such as duress, fraud or misrepresentation is proved.
- Duress is an issue of fact that must be specifically pleaded and strictly proved; it cannot be raised for the first time on appeal.
- Normal financial pressure or a desire for a quick payout does not amount to legal duress sufficient to set aside a discharge voucher.
Court orders
#- 1.The appeal is dismissed with costs to the respondent
- 2.The judgment and decree of the Employment and Labour Relations Court delivered on 20th January 2022 in Kericho ELRC Cause No. 15 of 2020 is upheld

Quotable passages
#Verbatim from the judgment, each located to the page it appears on in the official PDF — so these can be cited and checked directly.
it is not permissible for matters and issues not raised at the trial court to be raised for the first time on appeal
Unless an employee can prove that the waiver was signed under duress, fraud, or misrepresentation, the agreement validly extinguishes all existing and future statutory and contractual claims.
Duress is fundamentally an issue of fact that must be specifically pleaded and strictly proved by way of evidence.
normal financial pressure or a desire to receive a quick cash payout does not equate to legal duress
The upshot is that the judgment and decree of the Employment and Labour Relations Court delivered on 20th January 2022 in Kericho ELRC Cause No. 15 of 2020 is hereby upheld.
Issues in the judgment
#Header misdescribes the court below as the Environment and Land Court in ELC No. 15 of 2020, contradicting the body of the judgment and the disposition.
The appellant's prayer refers to a memorandum of claim dated 7th June 2022, though the claim was filed in 2020.
