National Oil Corporation v John Mwangi Kaguenyu & 2 others [2019] KECA 884 (KLR)
The bottom line
#Kenya's Court of Appeal threw out a Kshs 37.5 million malicious prosecution award, confirming that reporting a crime to police isn't enough to make you liable.
What this practically means
#Executive summary
#Key legal issues
#Elements of the tort of malicious prosecution
The plaintiff must establish that the defendant instituted the prosecution, that it ended in the plaintiff's favour, that it was instituted without reasonable and probable cause, and that it was actuated by malice.
The Court adopted the classic Murunga formulation. Making a complaint to the police is not of itself sufficient; the police must independently investigate and decide to prosecute, so liability cannot rest solely on the fact that the defendant lodged the report that set the process in motion.
Whether the appellant's report to the Banking Fraud Unit was actuated by malice
The report was not actuated by malice; the appellant had a bona fide basis, as an audit showed products collected had not been paid for.
The 1st respondent collected petroleum products against deposit slips, but the bank reconciliation did not reflect his deposit. An audit established the products were unpaid for. The appellant therefore had reasonable grounds to report the matter to the Banking Fraud Unit, which conducted its own investigations before prosecution.
Role of police independence in malicious prosecution claims
Law enforcement agencies must investigate complaints independently and are not mere conduits for complainants; a defendant is not liable for matters of which he was unaware.
Relying on Kiiru v Mwamburi, the Court emphasised that police must act impartially and investigate thoroughly, considering both complainant's and suspect's versions. However, neglect to make reasonable use of available sources of information before instituting proceedings may evidence want of reasonable and probable cause and malice.
Legal principles established
#- A complainant who merely makes a report to the police is not liable for malicious prosecution where the police independently investigate and decide to prosecute; a plaintiff must affirmatively establish malice.
- Acquittal alone does not establish malicious prosecution; the four Murunga elements, including malice and absence of reasonable and probable cause, must all be proved.
