What this practically means
#Executive summary
#Key legal issues
#Compatibility of the 7-day notice of appeal requirement with the 30-day appeal period in section 85A of the Elections Act
The 2017 Rules are not inconsistent with the Elections Act, the Elections (Parliamentary and County Elections) Petition Rules 2017 or the 2010 Court of Appeal Rules; the notice of appeal is a reasonable notification mechanism and a mandatory prerequisite
Section 85A's 30-day limit governs filing of the appeal, not abolition of the notice of appeal. The notice formally notifies parties that the dispute has moved to the Court of Appeal and prevents ambush. The 2017 Rules are later in time, dedicated to election petition appeals, and rule 4(2) expressly provides they prevail over the 2010 Rules in the event of conflict.
Whether to strike out the notice of appeal or extend time despite non-compliance
The Court exercised its discretion under rule 6(5) of the 2017 Rules to extend time and decline striking out, since no party was prejudiced and the appeal could be determined within the prescribed timelines
Although timelines in electoral disputes must be strictly observed, the 2017 Rules confer discretion to determine the effect of non-compliance, balancing justice without undue regard to procedural technicalities against timeliness. The record of appeal was already before the Court, no prejudice was shown, and the three objects of the Rules (just, impartial and expeditious determination) would not be compromised.
Whether the KIEMS kit forms part of the register of voters and whether scrutiny should have been ordered
The KIEMS kit is not part of the register of voters under section 4 of the Elections Act; it is a gadget for biometric voter identification and transmission of results. Further, the appellant never pleaded or applied for its scrutiny.
Section 4 exhaustively defines the register of voters (poll, ward, constituency, county and residence registers) and the KIEMS kit is not among them. Section 44 establishes the integrated electronic electoral system and section 44A a complementary mechanism. Having failed to plead and lay a basis for scrutiny in the petition or the scrutiny application, the appellant cannot fault the trial court.
Whether the trial court erred in evaluating the evidence and on witness credibility
Credibility findings are the province of the trial court; the appellate court may intervene only where conclusions are perverse. No credible evidence supported the allegations of partiality, and the scrutiny report revealed no material irregularity.
Section 85A confines election appeals to matters of law. The Court cannot re-examine the probative value of evidence or calibrate credibility, per the Supreme Court in Gatirau Peter Munya. There was no report of partiality in the Polling Station Diary or Occurrence Book, and the trial judge's finding that PW13 was not a witness of truth was not perverse.
Whether failure to call presiding officers shifted the burden of proof
The burden of proof lay with the petitioner throughout; failure by respondents to call witnesses does not displace it
It was the appellant's duty to call cogent and credible evidence to prove the allegations in the petition. A petition cannot succeed merely because a respondent offered no evidence in rebuttal; the petitioner must adduce evidence of the nature that would entitle him to judgment even if no rebuttal were offered.
Legal principles established
#- Election petition appeals in the Court of Appeal lie on matters of law only; the Court's engagement with facts is limited to context and to whether the trial judge's conclusions are supported by the record or are perverse
- The KIEMS kit is not part of the register of voters as defined in section 4 of the Elections Act
- A notice of appeal is a mandatory prerequisite and jurisdictional precondition to an election petition appeal; the 7-day period in the 2017 Rules prevails over the 14-day period in the 2010 Rules
- Failure by a respondent to call a witness does not automatically allow a petition; the petitioner must first adduce evidence entitling him to judgment absent rebuttal
- Parties are bound by their pleadings; a court cannot grant relief not sought in the pleadings or applications
