Mwobi v Njoroge (Civil Appeal 314 of 2009) [2013] KECA 501 (KLR)
The bottom line
#Kenya's Court of Appeal voided a 14-year-old land judgment because the trial judge had earlier disqualified herself, ordering a fresh retrial before a different judge.
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 doctrine of waiver, estoppel and acquiescence applied so as to preclude the parties from objecting to the Judge who had earlier disqualified herself proceeding to hear and determine the case
- 2.Whether a judge who has disqualified herself from a matter can later resume jurisdiction and preside over the same case
- 3.Whether the proceedings and judgment conducted after the judge's disqualification were a nullity
Key legal issues
#Effect of a judge's prior disqualification on subsequent proceedings
Having disqualified herself, the judge could not later conduct the same trial and deliver judgment; the subsequent proceedings and judgment were a nullity irrespective of the parties' failure to object.
The judge had disqualified herself as a Commissioner of Assize on the ground that she was known to one of the parties. That ground did not dissipate on her appointment as Judge. Although the parties and advocates failed to raise the objection and arguably waived and acquiesced, disqualification is a matter of law. Justice must not only be done but be seen to be done, and the fair-minded observer would apprehend bias from a judge revisiting a matter she had once declined to hear.
Applicability of waiver, estoppel and acquiescence to judicial disqualification
Although the parties' conduct amounted to waiver and acquiescence generally, those doctrines cannot validate proceedings before a judge who has disqualified herself, because disqualification is a matter of law.
The court analysed the doctrines from Halsbury's Laws and local authority, accepted that the parties by silence and participation had waived their right to object and had acquiesced. However, it held that disqualification of a judge is a matter of law and not fact, so estoppel, waiver and acquiescence do not apply to cure the defect.
Test for bias and impartiality in Kenya
The court adopted Lord Denning's real likelihood test as stated in Metropolitan Properties v Lannon, looking at the impression given to right-minded persons, over Lord Goff's real danger test.
The court reviewed Kenyan precedent including Uhuru Highway v Exchange Bank (which had adopted R v Gough) and Kimani v Njoroge, where the majority preferred Lord Denning's formulation in Metropolitan Properties v Lannon. The court expressed agreement with the impression-on-right-minded-persons test and anchored the requirement of impartiality in Article 50 of the Constitution and section 77(9) of the repealed Constitution.
Role of advocates in alerting the court to disqualification
Advocates have a duty to study the file, acquaint themselves with the record and alert the court to a prior disqualification; their failure wasted judicial time and resources and contributed to the costs order.
The court noted that several advocates came on record over the years, evidenced by Notices of Change of Advocates, and a diligent advocate ought to have discovered the earlier disqualification and raised it. Although the failure did not validate the proceedings, the court criticised the advocates for allowing the judge to conduct the trial and reflected this in making no order as to costs.
Legal principles established
#- A judge who has disqualified herself from hearing a matter cannot, all factors remaining constant, later resume jurisdiction and preside over the same matter; proceedings conducted thereafter are a nullity
- Disqualification of a judge is a matter of law, not fact, and cannot be cured by estoppel, waiver or acquiescence of the parties
- On the test for apparent bias, the court adopts the reasonable and informed observer standard over the real danger test
Court orders
#- 1.The appeal is allowed
- 2.The judgment and decree of the High Court are set aside
- 3.The case is remitted to the superior court for a retrial before any other Judge of competent jurisdiction other than Khaminwa J
- 4.Each party shall bear her/his own costs of this appeal and the court below
The bench

- On appeal from
- High Court of Kenya at Mombasa
- HCCC No. 99 of 1999
- Jurisdiction invoked
- First appeal to the Court of Appeal under the applicable appellate framework (Court of Appeal jurisdiction over appeals from the High Court); decided as a first appeal on fact and law
Relief refused
#Determination of the remaining ten grounds of appeal on the merits
The court declined to address the other grounds because doing so would pre-empt the outcome of the retrial
Costs
Each party shall bear her/his own costs of this appeal and the court below.
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.
In the premises we shall allow the appeal. The judgement and decree of the High Court is set aside. We substitute therefor with an order remitting the case back to Superior Court for a retial before any other Judge of competent jurisdiction other than Khaminwa, J. who presided over the trial.
In the premises each party shall bear her/his own costs of this appeal and the court below.
We do not think that a Judge who has disqualified herself from a matter and all factors remaining constant can again in future purport jurisdiction and preside over the matter.
it is nonetheless our view that disqualification of a Judge is a matter of law and not fact. As such there can be no estoppel, waiver and acquiescence.
It must be remembered that justice must not only be done but must also be manifestly seen to be done.
Issues in the judgment
#The quotation of Article 50 in the judgment begins with an apparent typographical error ('Very person has the right...') instead of 'Every person'
The court states the matter before it as HCCC No. 99 of 1999 but the first ground of appeal refers to 'HCCC No.90 of 1990', an internal inconsistency in the case number
The court records the disqualification date inconsistently, at one point as 5th March 2013 (evidently an error for 2003) and elsewhere as 8th March 2003
