The Court of Appeal has reduced a Sh7.5 million defamation award against a Nairobi businessman to Sh3 million, holding that although his letter accusing a senior banker of corruption was defamatory, the original damages were excessive given the limited circulation of the publication.
In a judgment delivered on February 13, 2026, appellate judges Francis Tuiyott, Aggrey Muchelule and Joel Ngugi partially allowed an appeal filed by Paul Matumbi, proprietor of Prudential Valuers Limited, against Henry Tanui, a former Head of Credit at Consolidated Bank of Kenya.
The dispute arose from a February 26, 2008 letter Matumbi wrote to the bank’s Managing Director, copying the Board Chairman, complaining that his valuation firm had been unfairly denied work.
In the letter, Matumbi questioned Tanui’s academic qualifications and alleged the banker solicited “handouts” in exchange for professional favours.
Matumbi later admitted authoring the letter but told the court he wrote it “in anger” after what he considered unfair treatment, saying he had been advised to put his concerns in writing.
Tanui, who holds undergraduate and postgraduate degrees in financial services, testified before the High Court that he was summoned before the bank’s disciplinary committee to defend his qualifications and integrity and was cleared of wrongdoing.
He said the episode caused distress and contributed to his decision to leave the bank for Ecobank Kenya at a lower salary.
In December 2019, High Court judge Joseph Kiplagat Sergon found the allegations false and malicious, awarding Tanui Sh6 million in general damages and Sh1.5 million in exemplary damages, plus costs.
On appeal, Matumbi argued the letter was protected by qualified privilege because it was a complaint made to persons with a corresponding interest, and that no actual damage to reputation had been proven.
The appellate court rejected the defence, finding the privilege was defeated by malice.
The judges held that although grievances can in some cases be communicated to relevant persons, the tone and content of the letter went beyond what was reasonably necessary to raise a complaint.
The court also reaffirmed that in libel cases, injury to reputation is presumed and does not require proof of actual financial loss.
It ruled evidence showed Tanui was subjected to internal disciplinary scrutiny and suffered distress.
However, the court found the damages awarded were disproportionate because the letter was only seen by two senior bank officers and did not enter the public domain.
The judges reduced general damages from sh6 million to sh3 million, saying the original award fell outside the range of comparable awards for cases involving limited publication.
The court also struck out the Sh1.5 million exemplary damages award, ruling that malice alone is not sufficient to justify punitive damages unless the case falls within narrowly defined legal categories.
Judges ruled there was no evidence Matumbi stood to gain financially from the publication or that it formed part of a calculated profit-driven scheme, describing him as a private individual airing a grievance “in an improper and malicious manner.”
The court emphasised the need to balance protection of reputation with freedom of expression, ruling that reputation forms part of human dignity while free speech sustains democratic accountability.
The judges said justice in defamation cases lies in proportionality rather than excessive punishment.
