Njenga v Njenga [1985] KECA 43 (KLR)
The bottom line
#Kenya's Court of Appeal ruled that a child born during marriage is presumed legitimate unless disproven beyond reasonable doubt.
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 learned judge erred in holding that Njogu is a child of the marriage
- 2.Whether the parties had access to each other at any time when Njogu could have been begotten
- 3.Whether the presumption of legitimacy under section 118 of the Evidence Act was rebutted, including whether the gestation period relied on by the appellant was decisive
- 4.What standard of proof applies to evidence in rebuttal of the presumption of legitimacy
Key legal issues
#Standard and mode of rebutting the presumption of legitimacy under section 118 of the Evidence Act
The presumption of legitimacy arising from birth during a valid marriage is rebuttable only by proof, beyond reasonable doubt, that the parties had no access to each other at any time when the child could have been begotten; a gestation period of 270-280 days was not abnormal and could not displace it.
Section 118 makes birth during marriage conclusive proof of legitimacy unless non-access is shown. The court found the parties lived in the same house during the conception period, and Margaret Nyambura corroborated an occasion when the parties were together overnight. Relying on Preston-Jones, Gaskill and Hadlum, the court held that even extended gestation intervals could not be ruled out without medical evidence, so a fortiori the 270-280 day period relied on by the appellant was unremarkable. The appellant's evidence therefore failed to meet the required conclusive standard.
Whether the trial judge erred in holding that Njogu is a child of the marriage
No error in the finding; the finding that Njogu is a child of the family was upheld.
The respondent's evidence of access was supported by the appellant's own admissions (that he moved into the Langata house and told the respondent he did not want sexual relations, showing opportunity), and by Margaret Nyambura's evidence that she saw both parties sleeping on the sofa set one morning. On that evidence it could not reasonably be said the appellant had no opportunity of access. The appeal on the remaining ground therefore failed and was dismissed with costs.
Legal principles established
#- A child born during the continuance of a valid marriage is presumed legitimate under section 118 of the Evidence Act, and that presumption can only be rebutted by evidence of non-access strong, distinct, satisfactory and conclusive - putting the matter beyond reasonable doubt, not by a mere balance of probability.
- Where access is shown, the presumption of legitimacy is not defeated by evidence that another man may also have had intercourse with the wife; the law requires positive proof that the husband had no intercourse which might have led to the birth.
- Allegations that would bastardise a child born in wedlock are treated as seriously as criminal allegations because of their grave and life-long consequences, notwithstanding that the proceedings are civil.
Court orders
#- 1.Appeal dismissed with costs
- 2.Consent order disposing of the first eleven grounds of appeal (recorded by the court and signed by both advocates)
The bench
#One judgment of the whole court — no separate or dissenting opinions.
Wrote the judgment
Delivered the leading judgment. Held that section 118 of the Evidence Act raises a rebuttable presumption of legitimacy for a child born during a valid marriage; the appellant could only displace it by proving non-access beyond reasonable doubt. The evidence of shared residence and the corroborating testimony of Margaret Nyambura showed opportunity of access, so the trial judge's finding that Njogu was a child of the marriage disclosed no error. Appeal dismissed with costs.
The standard demanded of the evidence in rebuttal of paternity: "is high. The evidence... must be strong, distinct, satisfactory and conclusive"p. 3
Wrote the judgment
Wrote a separate concurring opinion. Emphasised that section 118 adopts date of birth, not conception, as the test of legitimacy, and that the presumption can yield only to positive proof of non-access at the relevant time. Reviewed the English authorities including Bury v Phillpot, Gordon v Gordon and Morris v Davies to show the presumption is not repelled by a mere balance of probability.
The presumption of legitimacy could be rebutted only by evidence which puts the matter beyond reasonable doubt.p. 3
Wrote the judgment
Wrote a brief separate concurrence. Observed that the 360-day interval in Preston-Jones v Preston-Jones would seem unacceptably long without special medical evidence, but agreed that evidence in rebuttal under section 118 of the Evidence Act must be strong, clear and conclusive before the presumption of legitimacy is overturned.
yet I agree that the evidence in rebuttal, permitted by section 118 of the Evidence Act (cap 80) should be strong, clear and conclusive.p. 5
- On appeal from
- High Court of Kenya
- Jurisdiction invoked
- First appeal to the Court of Appeal from the High Court in proceedings under the Guardianship of Infants Act (cap 144); no specific constitutional or appellate jurisdiction provision is cited in the judgment
Relief refused
#Appellant's plea that Njogu is not his child / reversal of the finding that Njogu is a child of the marriage
The appellant failed to prove non-access beyond reasonable doubt; the evidence did not meet the high standard required to rebut the presumption of legitimacy
Costs
Appeal dismissed with costs to the respondent
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.
I would dismiss the appeal with costs.
For these reasons I also agree that this appeal should be dismissed with costs.
I agree with the opinion of Madan and Nyarangi, JJA. Apart from observing that the period of time which had elapsed of 360 days in Preston-Jones v Preston-Jones [1951] 1 All ER 124 would seem to be unacceptably long without special medical evidence to support it; yet I agree that the evidence in rebuttal, permitted by section 118 of the Evidence Act (cap 80) should be strong, clear and conclusive.
The presumption of legitimacy could be rebutted only by evidence which puts the matter beyond reasonable doubt.
The presumption can yield only to positive proof of non-access at the relevant time
Issues in the judgment
#The judgment states inconsistently that Njogu was born on August 24, 1980 in the leading judgment but on August 24, 1981 in Madan JA's opinion
The copy of the judgment bears no case number or formal title; only the parties' names (Njenga) and the child's name (Njogu) appear
The transcription of Platt Ag JA's concurrence is garbled ('As Platt Ag JA also agree it is so ordered'), and the document is a certified copy rather than the original judgment
