The bottom line
#Kenya's Court of Appeal allowed Centurion Engineers to enforce an arbitral award against KEBS, holding a public body cannot dodge payment by raising procurement law objections too late.
What this practically means
#Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.Whether the arbitral award was contrary to the public policy of Kenya within the meaning of section 35(2)(b)(ii) of the Arbitration Act
- 2.Whether the variation of the original contract by way of the supplementary agreement breached section 47 of the Public Procurement and Disposal Act as read with regulation 31(c)
- 3.Whether the respondent, having instructed the extra works and never raised the PPDA earlier, was estopped from raising the procurement-law objection on appeal
Key legal issues
#Whether the arbitral award upholding variations exceeding 15% of the contract sum was contrary to public policy under section 35(2)(b)(ii) of the Arbitration Act
The award was not contrary to public policy; the PPDA objection was an afterthought by a respondent that used a private document and never referred to the PPDA, and there was evidence of liability to pay.
The Court found the variation was a mutual agreement evidenced by instructions and a supplementary contract. The respondent never raised the PPDA during the works, the tender and contract documents did not reference it, and the arbitrator found no evidence of breach of section 47. Unlike cases where liability was unproven, here the works were completed and the premises occupied, so enforcement was not injurious to the public good.
Whether the respondent was estopped from raising the PPDA breach for the first time on appeal
The respondent was estopped from raising the statutory objection too late in the day.
The Court found as a fact that at no point did the respondent raise the provisions of the PPDA, nor did it inform the appellant that it would not pay beyond 15% of the original contract. Having instructed the extra works, signed the supplementary agreement and taken possession of the completed premises, the respondent could not turn around at the last minute to disown its contractual obligations.
Whether the appellant was entitled to payment for the additional works on a quantum meruit basis
The appellant was entitled to the value of the work done under the contract as mutually agreed; the arbitral award recognizing that entitlement stands.
It was not disputed that the appellant carried out and completed the additional works as instructed and handed over the project, which the respondent has used in its day-to-day business without paying. The supplementary agreement listed the exact amounts of each additional work, evidencing a meeting of minds, and the respondent's refusal to pay was a 'won't pay' rider rather than a want of liability.
Legal principles established
#- A court will not set aside an arbitral award as contrary to public policy where the procuring entity itself never invoked the procurement statute and there is proof of liability for the work done; a party cannot hide behind statutory violation it participated in.
- Parties are bound by the terms of their contract and courts will not rewrite contracts for them.
Court orders
#- 1.The ruling of the High Court dated December 9, 2016 is set aside
- 2.The arbitral award of Mr Onesmus Mwangi Gichuri dated May 5, 2015 is recognized as binding and adopted as judgment of the court
- 3.The appeal is allowed with costs to the appellant

- On appeal from
- High Court
- Jurisdiction invoked
- First appeal to the Court of Appeal from the High Court in a matter arising from the setting aside of an arbitral award under section 35 of the Arbitration Act
Relief refused

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.
The upshot of this is that the ruling of the High Court dated December 9, 2016 be and is hereby set aside. The arbitral award of Mr Onesmus Mwangi Gichuri dated May 5, 2015 be and is hereby recognized as binding and shall be adopted as judgment of the court.
The appeal is accordingly allowed with costs to the appellant.
The respondent cannot be seen to hide under the provisions of the PPDA, yet it was never referred to in the contract between the parties. The respondent being a public body ought to have governed itself as such and not at the last-minute try and turn tables.
In this instance, there is evidence of liability to pay, but with a rider of ‘won’t pay’.
A court of law cannot rewrite a contract between parties. The parties are bound by the terms of their contract, unless coercion, fraud or undue influence are pleaded or proved.
Issues in the judgment
#The judgment refers to the arbitrator's award as dated November 28, 2013 in the narrative, but the operative order adopts an award of the same arbitrator dated May 5, 2015; the November date appears to refer to the first (set aside) award while the May 5, 2015 award is the one under challenge, but the sequence is not expressly clarified.
