#Standard of proof of adultery in matrimonial proceedings
The High Court erred in applying the criminal standard of proof beyond reasonable doubt. The correct standard, as in Wangari Mathai v Mwangi Mathai, is that the court must be satisfied as to be sure, equating to a preponderance of probability; criminal law analogies have no place in the Divorce Court.
The court relied on Wangari Mathai, which equated the burden of proof for matrimonial offences to being satisfied as to be sure, expressly staying away from the criminal law analogy. Rayden on Divorce confirms that a divorce suit is a civil proceeding and adultery may be proved by preponderance of probability. Section 10 of the Matrimonial Causes Act requires only that the court be satisfied on the evidence, with no reference to proof beyond reasonable doubt.
Whether the evidence established adultery notwithstanding the trial judge's findings
On re-evaluation, the unchallenged evidence of PW2 of compromising circumstances, together with the respondent's failure to defend the petition and the letter suggesting a child by another man, satisfied the court that adultery with Wa Teresa was proved.
The court conducted a fresh evaluation of the evidence on appeal. The trial judge misdirected himself in finding the respondent's letter was written in a huff, since that would have been for the respondent to say and she filed no Answer confirmed under oath. The evidence of opportunity and inclination, being unchallenged, raised a presumption of adulterous association which the court accepted.
Fidelity to the Wangari Mathai standard
The court clarified that it was not departing from the standard set in Wangari Mathai; the trial judge had simply failed to consider that the case equated 'satisfied as to be sure' with a standard distinct from the criminal standard.
The court distinguished between the phrase 'beyond reasonable doubt' as used in Wangari Mathai and the criminal analogy. Wangari Mathai itself explained that the standard meant more than a mere balance of probabilities: the court must feel sure of the guilt of the respondent. Had the trial judge adopted that course, he would have found adultery proved.
Legal principles established
#- Adultery, like any other matrimonial offence, need not be proved to the criminal standard of proof beyond reasonable doubt; the court must be satisfied as to feel sure, which is satisfaction on a preponderance of probability.
- The Matrimonial Causes Act (Cap 152) does not prescribe proof beyond reasonable doubt; the proper burden is that the court feels certain or sure that a matrimonial offence has been committed.
- Unchallenged evidence of compromising circumstances showing opportunity and inclination raises a presumption of an adulterous association which may be acted upon, particularly where the respondent does not defend the petition.
