Mary Wambui Munene v Peter Gichuki King'ara & 2 others
The bottom line
#Supreme Court restored Mary Wambui Munene's win because the election petition was filed after the 28-day constitutional deadline.
What this practically means
#Mary Wambui Munene was declared winner of the Othaya parliamentary seat in March 2013. Her opponent challenged the result, but filed the petition six days late – after the 28-day period set by the Constitution. The law that allowed the extra time was later ruled unconstitutional, and that ruling applied to this case. So the entire challenge was void from the start. The Supreme Court reinstated Munene’s victory and ordered each side to pay its own costs.
Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.whether these proceedings were a nullity ab initio, having been premised on a Petition filed out of time at the High Court
- 2.whether the Court of Appeal in arriving at its decision exceeded its jurisdiction by delving into issues of fact
- 3.whether the Court of Appeal misdirected itself when it made its finding on the issue of scrutiny and re-count
- 4.when did the vacancy for the Member of the National Assembly for Othaya occur?
Key legal issues
#Whether the petition in the High Court was a nullity for being filed out of time under Article 87(2) of the Constitution.
The petition was a nullity because it was filed on 8th April 2013, six days after the 28-day period from the declaration of results on 5th March 2013, and was based on Section 76(1)(a) of the Elections Act which had been declared inconsistent with Article 87(2) of the Constitution.
The Supreme Court applied its decision in Joho, which declared Section 76(1)(a) of the Elections Act inconsistent with Article 87(2) of the Constitution. The Court held that the declaration of invalidity applied retrospectively to the date of commencement of the Elections Act (2nd December 2011). Since the petition was filed on 8th April 2013, six days after the constitutional deadline of 2nd April 2013, and was founded on the invalidated provision, the entire proceedings were a nullity ab initio. The Court rejected the argument that the appellant had acquiesced, noting that the issue of jurisdiction could be raised at any time. The Court also clarified that the retrospective effect did not apply to cases already finally determined, but this case was still pending.
Whether the Court of Appeal exceeded its jurisdiction by delving into issues of fact.
The Court did not determine this issue because it found the proceedings were a nullity ab initio, rendering the question moot.
Having concluded that the entire proceedings before the High Court and Court of Appeal were a nullity because the petition was filed out of time, the Supreme Court held that it was not necessary to consider the other issues raised in the appeal, including whether the Court of Appeal exceeded its jurisdiction by delving into issues of fact.
Legal principles established
#- A declaration that a law is unconstitutional applies from the date that law was enacted, unless the court says otherwise.
- Any legal proceedings based on a law that violates the Constitution are automatically null and void from the beginning.
- An election petition must be filed within 28 days of the official declaration of results, not from the date of gazettement.
- The issue of whether a court has jurisdiction can be raised at any time, even by a party who did not raise it earlier.
- The retrospective effect of a court ruling does not reopen cases that were already finally decided, but applies to pending cases.
Court orders
#- 1.The Petition of Appeal dated 8th April, 2014 is hereby allowed.
- 2.The Judgement, consequential Orders and the proceedings before the Court of Appeal in Nyeri Civil Appeal No. 31 of 2013 are hereby declared null.
- 3.All the costs in the proceedings before the High Court, the Court of Appeal and this Court, be borne by each party respectively.
- 4.For the avoidance of doubt, the declaration of the result of the election by the Independent Electoral and Boundaries Commission in respect of the seat for the Othaya Member of the National Assembly is hereby restored.

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.
The Petition of Appeal dated 8th April, 2014 is hereby allowed.
The Judgement, consequential Orders and the proceedings before the Court of Appeal in Nyeri Civil Appeal No. 31 of 2013 are hereby declared null.
For the avoidance of doubt, the declaration of the result of the election by the Independent Electoral and Boundaries Commission in respect of the seat for the Othaya Member of the National Assembly is hereby restored.
we are convinced that for the benefit of certainty and consistency, the declaration of invalidity must apply from the date of commencement of the Elections Act, i.e. 2nd December 2011.
If an act is void then it is in law a nullity. It is not only bad, but incurably bad. There is no need for an order of the court to set it aside. It is automatically null and void without more ado, though it is sometimes convenient to have the court to declare it to be so.
But the retrospective effect of a judicial decision is excluded from cases already finally determined. This is the common law position.
Key timeline
#Practical implications
#Always verify the constitutional validity of the statute you rely on
When filing any case, check whether the law you are using has been challenged or declared unconstitutional. If a statute is later struck down, the declaration may apply retroactively, making your whole case a nullity. In election petitions, the constitutional deadline (28 days from result declaration) overrides any statutory provision that extends it.
Monitor legal challenges to laws that affect your operations
If your business depends on a specific statutory provision (e.g., licensing deadlines, tax periods), a court ruling that the provision is unconstitutional could apply retroactively and invalidate actions taken under it. Stay informed about constitutional challenges to laws in your sector, and seek legal advice before relying on a provision that may be vulnerable.
File election petitions within 28 days of result declaration
If you plan to challenge an election result, you must file your petition within 28 days from the date the winner is officially declared, not from the date the result is published in the Kenya Gazette. Relying on a law that allows a longer period is risky—that law may be struck down and your petition will be dismissed as filed too late.
Frequently asked questions
#What is the deadline for filing an election petition in Kenya?+
Under Article 87(2) of the Constitution, an election petition must be filed within 28 days after the declaration of the election results by the Independent Electoral and Boundaries Commission. The date of gazettement does not extend this period.
Can a law declared unconstitutional in Kenya apply to past cases?+
Yes. The Supreme Court has ruled that a declaration of invalidity applies from the date the law was enacted, unless the court limits it. This means it can affect pending cases, but not cases that were already finally decided before the ruling.
What happens if an election petition in Kenya is filed out of time?+
The entire proceedings are a nullity from the start. The High Court loses jurisdiction to hear the case, and any judgment from the Court of Appeal or Supreme Court based on that petition is also void. The original election result stands.
Who pays the costs in a Kenyan election petition that is declared a nullity?+
The court may order each party to bear their own costs, as happened in the Mary Wambui Munene case. This is because the nullity arises from a legal error rather than the conduct of the parties, so no one is penalised with the other side’s legal fees.
