Sylvanus Oiya Ongoro v Director of Criminal Investigations & 4 others
The bottom line
#Kenya's Court of Appeal dismissed this appeal because alleging your rights were violated is not enough—you must prove it with specific evidence.
What this practically means
#Executive summary
#Key legal issues
#Precision in pleading constitutional violations (Anarita Karimi principle)
The appellant merely asserted violations of Articles 27, 28, 29, 47 and 49 without demonstrating how each provision was infringed; the claim failed for want of specificity and proof
Reinforcing Anarita Karimi Njeru and Communication Commission of Kenya v Royal Media Services, the Court held that a petitioner must show the rights infringed, the constitutional provisions contravened, and the manifestation of contravention. The appellant did not show discrimination under Article 27, did not identify which aspect of Article 47(1) was breached, and produced no proof of assault or of being denied reasons for arrest. Allegation without demonstration cannot found a constitutional remedy.
Burden of proof in constitutional petitions
A party alleging violation of fundamental rights bears the onus of proving the violation on a balance of probabilities
The Court restated that rights are inherent and not granted by the State, but the corollary is that whoever alleges violation must prove it. Having reconsidered and reevaluated the evidence as a first appellate court, it found the appellant had not discharged this onus; police received information of crimes, reasonably believed the appellant involved, arrested and prosecuted him, and he was found to have a case to answer.
Malicious prosecution and reasonable and probable cause
The appellant failed to show that his arrest and prosecution were actuated by malice; the prosecution was founded on a report and investigations constituting reasonable and probable cause
Relying on James Karuga Kiiru v Joseph Mwamburi, the Court held that prosecution is not prima facie tortious unless done dishonestly or unreasonably. The appellant was acquitted only under section 215 of the Criminal Procedure Code on insufficiency of evidence after being found to have a case to answer, which does not establish that police acted without reasonable cause or dishonestly. Mere allegation of malice without demonstration fails.
Validity of affidavits commissioned by a Commissioner for Oaths whose stamp bears a Nairobi address
The High Court erred in striking out the affidavits; a Commissioner for Oaths may commission documents and administer oaths anywhere in Kenya regardless of the address on the stamp
Section 4 of the Oaths and Statutory Declarations Act empowers a commissioner for oaths, in any part of Kenya, to administer oaths and take affidavits. The record showed the appellant was never asked to explain whether he appeared before the commissioners, so the finding that he had not appeared was speculative. However, the error did not affect the outcome because the petition failed on the merits in any event.
Duty of police not to assault arrested persons
The Court affirmed the principle that assaulting a defenceless arrested person violates Article 244(c) and the Constitution, but found the respondents had denied the claim and the appellant proved nothing
While asserting that police have no right to assault an arrested and defenceless person, the Court noted the claim of assault and manhandling was denied by the respondents and the appellant did not discharge his burden of proving it. The observation on Article 244(c) is obiter dictum; the ratio is the failure of proof.
Legal principles established
#- A Commissioner for Oaths may commission documents and administer oaths in any part of Kenya and is not limited to the address indicated on his or her stamp; the address on a commissioning stamp does not invalidate an affidavit sworn elsewhere in Kenya
- A party alleging violation of constitutional rights must demonstrate with precision the provisions violated and the manner of violation, and must prove the violation on a balance of probabilities; mere allegation is insufficient
- Acquittal on the merits does not of itself establish malicious prosecution; to prosecute a person is not prima facie tortious unless done dishonestly or unreasonably and without reasonable and probable cause
