Mate & another v Wambora & another
The bottom line
#Courts cannot stop Parliament's internal processes unless there is a clear constitutional violation.
What this practically means
#The Supreme Court ruled that courts should not interfere with ongoing parliamentary proceedings, like an impeachment, unless there is a clear threat to the Constitution. This case involved a governor's impeachment by the Embu County Assembly. The High Court had stopped the process, but the Supreme Court said that was wrong. It emphasized separation of powers: each arm of government must respect the others. Constitutional timelines, such as those for impeachment, are mandatory and cannot be extended by any court.
Executive summary
#Questions the Court framed
#The issues the Court set itself to decide, in its own words.
- 1.whether this court has the jurisdiction under article 163(4)(a) of the Constitution to determine this appeal
- 2.whether the court can interfere with parliamentary processes which are in actual progress
- 3.whether the court can interfere with constitutional timelines
- 4.what are the requisite orders in this case?
Key legal issues
#Whether the Supreme Court has jurisdiction under Article 163(4)(a) to hear an appeal arising from contempt proceedings that also involves the interpretation and application of the Constitution.
The Supreme Court has jurisdiction under Article 163(4)(a) because the appeal raises issues concerning the interpretation and application of the Constitution, specifically the doctrine of separation of powers and the privileges and immunities of legislative bodies, which transcend the mere question of contempt.
The Court held that the issues in the appeal had transcended the parties as individuals and crystallized into a conflict involving the interpretation and application of the Constitution, thus falling within the jurisdiction of the Supreme Court under Article 163(4)(a). The law of contempt of court, in this context, could not be screened from the grasp of 'interpretation and application of the Constitution.' The Court relied on its earlier ruling in the same matter (Application No 37 of 2014) which had already determined that the jurisdictional threshold was met.
Whether a court can interfere with parliamentary or legislative processes that are in actual progress, particularly through conservatory orders.
A court should not interfere with ongoing legislative processes unless there is a clear and imminent threat of a constitutional violation. The court must exercise restraint and respect the doctrine of separation of powers, allowing the legislative body to complete its processes before judicial intervention.
The Supreme Court reviewed the doctrine of separation of powers and the privileges and immunities of legislative bodies. It held that while courts have the mandate to determine the constitutionality of actions by any State organ, they must be guided by restraint and should not supervise the workings of Parliament. The court found that the High Court's conservatory orders, which halted the impeachment process, were an unwarranted intrusion into the constitutional mandate of the County Assembly. The court emphasized that the County Assembly was operating within its constitutional scheme and its Standing Orders, and there was no basis for the court to intervene at that stage.
Whether constitutional timelines are amenable to court changes or variations.
Constitutional timelines are mandatory and binding on all State organs, including the courts. They cannot be varied or extended by any court.
The Court cited its own decision in Raila Odinga and the Court of Appeal decision in Ferdinand Waititu to affirm that timelines set by the Constitution are not negotiable and cannot be extended. Applying this principle to the case, the Court noted that the County Assembly's Standing Orders provided a seven-day timeline for the impeachment process. The High Court's conservatory order effectively interfered with this timeline, placing the Speaker in a dilemma between obeying the court order and complying with his constitutional and procedural obligations. The Supreme Court held that this was untenable.

Each party to bear own cost.
This court will not question each and every procedural infraction that may occur in either of the Houses of Parliament. The court cannot supervise the workings of Parliament. The institutional comity between the three arms of government must not be endangered by the unwarranted intrusions into the workings of one arm by another
These timelines set by the Constitution and the Elections Act are neither negotiable nor can they be extended by any court for whatever reason.
Key timeline
#Practical implications
#Challenge parliamentary actions carefully
When seeking to stop legislative proceedings, you must demonstrate a clear and imminent constitutional violation, not just procedural infractions. Courts will not supervise Parliament. Frame arguments around separation of powers and show that the harm outweighs the institutional comity. Also note that constitutional timelines are absolute—no court can extend them.
Legislative stability affects investment
This ruling reinforces that county assemblies can conduct impeachment processes without premature judicial interference. For businesses operating in devolved units, this means political processes like impeachment will run their course. Plan for potential leadership changes and ensure your contracts and engagements account for such constitutional timelines.
Your rights vs. legislative process
If you are affected by a legislative action (e.g., impeachment of a local leader), you cannot easily stop it through court orders unless you prove a direct constitutional threat. The court will let the process finish first. Your remedy may come after the fact, through judicial review of the final outcome, not by halting proceedings mid-way.
Frequently asked questions
#Can Kenyan courts stop Parliament from impeaching a governor?+
Generally no. The Supreme Court ruled that courts should not interfere with ongoing legislative processes like impeachment unless there is a clear and imminent threat to the Constitution. The court must respect separation of powers and let the process run its course.
What is the doctrine of separation of powers in Kenya?+
It means the three arms of government—executive, legislature, and judiciary—are independent and must not interfere with each other's functions. In this case, the Supreme Court said courts cannot supervise Parliament's internal workings, as that would endanger institutional comity.
Are constitutional timelines flexible in Kenya?+
No. The Supreme Court confirmed that timelines set by the Constitution (e.g., for impeachment) are mandatory and cannot be extended by any court. All state organs, including the judiciary, must respect them.
What happens if a county assembly ignores a court order in Kenya?+
It can be held in contempt, but the Supreme Court in this case annulled the contempt finding because the underlying court order was an unwarranted intrusion into Parliament's mandate. The Speaker faced a dilemma between obeying the court and following constitutional timelines. The court ruled that such orders should not be issued in the first place.
