The bottom line

#

Being acquitted of a criminal charge in Kenya is not enough to win a malicious prosecution case—you must also prove police acted maliciously and without any reasonable basis.

What this practically means

#

Executive summary

#
The Plaintiffs sued the Attorney General, the OCS, the DCI and the County Government of Laikipia claiming general, special, aggravated and exemplary damages for false imprisonment, malicious arrest and malicious prosecution. They alleged that following their arrest on 8th May 2019 and prosecution in Nanyuki Criminal Case No. 588 of 2019 for tampering with survey marks under Section 29(a) of the Survey Act, they were detained, suffered loss of liberty, reputational injury and legal expenses, and were acquitted under Section 215 of the Criminal Procedure Code on 16th May 2022. The Defendants filed defences asserting lawful action on reasonable and probable cause in exercise of statutory duties, but called no witnesses at trial. The court framed four issues: whether malicious prosecution was proved, whether unlawful arrest and false imprisonment were proved, entitlement to relief, and costs. Applying the settled four-element test from Murunga and Mbowa, and Nzoia Sugar on the insufficiency of acquittal alone, the court held that although the prosecution terminated in the Plaintiffs' favour, they failed to prove absence of reasonable and probable cause, malice, or the Defendants' legal responsibility for the decision to prosecute. The court further observed that the DPP, vested with exclusive prosecutorial mandate under Article 157, was not joined and was ordinarily a necessary party, and that no evidence showed investigators manipulated the prosecutorial process. Allegations of political and cartel influence were unsupported. The suit was dismissed with each party bearing its own costs.

Key legal issues

#
01

Malicious prosecution - ingredients and proof

Holding

Plaintiffs proved institution of proceedings and acquittal, but failed to prove absence of reasonable and probable cause and malice

Reasoning

The court applied the four-part test from Murunga and Mbowa. The acquittal under Section 215 of the Criminal Procedure Code merely showed the prosecution failed to meet the criminal standard of proof; it did not show the prosecution lacked reasonable and probable cause at inception. Plaintiffs produced no investigation file, witness statements or Occurrence Book extracts to show investigators ignored exculpatory evidence, and allegations of political motive were unsupported by any evidence.

02

Non-joinder of the Director of Public Prosecutions

Holding

The DPP, vested with exclusive constitutional power to institute and discontinue prosecutions under Article 157, was a necessary party; without evidence that police misled the DPP, no responsibility could be attributed to the Defendants sued

Reasoning

The court held that the decision to charge rests with the DPP exercising independent prosecutorial discretion. Although failure to sue the DPP is not invariably fatal where evidence shows investigators manipulated the process, no such evidence was presented, so there was no evidential basis to attribute the prosecutorial decision to the police officers or the Attorney General.

p. 6
03

Burden of proof despite uncontroverted evidence

Holding

Even where defendants adduce no evidence, plaintiffs must still prove their claim on a balance of probabilities under Sections 107-109 of the Evidence Act

Reasoning

The court noted the defendants did not participate or call witnesses, but this did not relieve the plaintiffs of the legal burden. Applying Kiema v Kenya Cargo Hauling Services, the onus lies on he who alleges; the plaintiffs had to prove each element of the tort, which they failed to do.

p. 4

Legal principles established

#
  • Acquittal per se does not establish absence of reasonable and probable cause for a malicious prosecution claim; spite or ill-will must be proved
  • Reasonable and probable cause is judged objectively on the material within the prosecutor's knowledge at the time of instituting proceedings
  • Where the impugned conduct concerns the decision to prosecute, the DPP is ordinarily a necessary party

Court orders

#
  1. 1.The Plaintiffs' suit is hereby dismissed
