James Karuga Kiiru v Joseph Mwamburi & 2 others [2001] KECA 354 (KLR)
The bottom line
#Kenya's Court of Appeal ruled police acted lawfully in arresting and detaining a poaching suspect, and innocence alone does not make police liable.
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 first defendant was at fault in making the arrest, i.e. whether the defendants had reasonable cause to suspect that the appellant had committed an offence
- 2.Whether the first defendant was at fault in taking the appellant to Garsen and Hola before taking him back to Malindi
- 3.Whether the prosecution was malicious, i.e. whether the prosecutor acted dishonestly or unreasonably, and whether there was reasonable and probable cause for the prosecution
Key legal issues
#Whether the arrest of the appellant was lawful (false imprisonment - the arrest)
The arrest was lawful: the defendants discharged the burden of proving reasonable cause to suspect the appellant of an offence, so the first defendant was not guilty of false imprisonment in making the arrest
The court applied the principle that once arrest and detention are established, the defendant must justify them by proving reasonable cause for suspicion. Here the evidence that the first two defendants had received information implicating the appellant in poaching-related offences was uncontradicted and overwhelming, and they reasonably believed it. The trial judge was entitled to act on that evidence and to find that it afforded reasonable cause to suspect the appellant had committed an offence, so the first defendant was not guilty of false imprisonment in making the arrest.
Whether taking the appellant to Garsen and Hola police stations before returning him to Malindi was lawful
A constable may do what is reasonable to investigate a suspicion against a person in his custody, including taking him to other stations; the measures taken here were reasonable and the appellant willingly co-operated, so no false imprisonment arose
The court recognised that a constable has greater powers than an ordinary person over someone in custody: he may take the suspect to places such as his house or workplace to verify the suspicion or test an alibi, so long as the measures are reasonable. Moving the appellant to Garsen and Hola for investigation during the fourteen days was, on the facts, reasonable, and because the appellant willingly co-operated in all that was done he could not complain of it as false imprisonment.
Whether the prosecution was malicious and without reasonable and probable cause
The malicious prosecution claim failed: the appellant did not discharge the onus of proving that the prosecutor did not act honestly or reasonably, and the submission that there was no reasonable and probable cause lacked merit
The court distinguished malicious prosecution from wrongful arrest and detention: to prosecute is not prima facie tortious, and the person prosecuted bears the onus of proving that the prosecutor did not act honestly or reasonably. On the evidence there was nothing to show the prosecutor had not acted honestly and reasonably, and the faintly argued submission of absence of reasonable and probable cause failed. Even if the appellant was innocent, absent necessary evidence a police officer who has only done his duty in investigating an offence is not liable.
Whether the trial judge ought to have assessed damages despite dismissing the claim
It is desirable practice for a trial judge to assess damages even when giving judgment for the defendant; the learned judge here omitted to do so, though the point was academic as the appeal failed on liability
Although Khamoni J dismissed the damages claim, he did not assess the damages the plaintiff would have recovered had he succeeded on appeal. Endorsing Law JA's dictum in Selle v Associated Motor Boat Co, the court stated that a trial judge in a damages suit should always make a finding on quantum even when giving judgment for the defendant, since that course avoids much time and expense. The point was academic here because the appeal failed on liability.
Legal principles established
#- In a claim for false imprisonment arising from an arrest, the burden is on the defendant to prove that there was reasonable cause to suspect the arrested person of committing an offence
- A police officer who has taken into custody a person reasonably suspected of an offence may do what is reasonable to investigate the suspicion, including moving the suspect between places and stations, provided the measures taken are reasonable
- Malicious prosecution differs from wrongful arrest and detention: prosecution is not prima facie tortious, and the onus of proving that the prosecutor did not act honestly or reasonably lies on the person prosecuted
- A trial judge in a suit for damages should make a finding on the amount of damages even when giving judgment for the defendant, to avoid time and expense if the matter goes on appeal
Court orders
#- 1.The appeal is dismissed with costs
The bench
#One judgment of the whole court — no separate or dissenting opinions.
- On appeal from
- High Court (described in the judgment as 'the superior court')
- Jurisdiction invoked
- Not stated in the judgment; the matter is a first appeal from a judgment of the superior court to the Court of Appeal
Relief refused
#Damages for false imprisonment
The arrest was justified: the defendants proved reasonable cause to suspect the appellant of an offence based on trustworthy information they reasonably believed
Damages for malicious prosecution
The appellant failed to discharge the onus of proving that the prosecutor did not act honestly or reasonably, and the absence of reasonable and probable cause was not made out
Damages for loss of business
The claim fell with the appeal as a whole; no liability was established to ground any of the heads of damages claimed
Costs
The appeal was dismissed with costs (the appellant to pay the respondents' costs); no other costs order was made
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.
For the reasons above stated, this appeal fails. It is accordingly dismissed with costs.
The burden was on the defendants to prove that they had reasonable cause for suspecting that the appellant had committed an offence.
When a constable has taken into custody a person reasonably suspected of an offence, he can do what is reasonable to investigate the matter and to see whether the suspicions are supported or not by further evidence.
To prosecute a person is not prima facie tortious, but to do so dishonestly or unreasonably is.
It may well be that the appellant was innocent all the time, but there is no reason in the absence of necessary evidence for making a police officer liable when he had only done his duty in investigating an offence.
It is always desirable, in a suit for damages, for the trial judge to make a finding as to the amount to which he thinks the plaintiff would be entitled if successful, even though he gives judgment for the defendant.
Issues in the judgment
#The names of the first and second defendants are not stated anywhere in the judgment; they are identified only by description, so the case title and party list are reconstructed from the descriptions available
No appeal number or superior court suit number is given anywhere in the judgment for either the appeal or the proceedings below
