Kenya's Courtroom Reckoning: Inside the Gachagua Constitutional Case

When the Supreme Court of Kenya convened on 22 May 2026 to hear arguments in Rigathi Gachagua's challenge to his impeachment, the packed courtroom reflected a political system wrestling with its own constitutional architecture. The Deputy President, removed from office by the Senate in October 2024 and subsequently acquitted of the criminal charges that accompanied that removal, has staked his legal challenge on the procedural integrity of the impeachment process itself. What began as a political dispute within Kenya's ruling coalition has evolved into a defining constitutional moment, one whose consequences will extend far beyond any single individual's political future.
The case turns on whether the Senate's impeachment mechanism — a power the 2010 constitution introduced to check executive authority — was applied in a manner consistent with constitutional guarantees of due process. Gachagua's legal team argues that the charges levelled against him were substantively insufficient and procedurally rushed, denying him adequate time to mount a defence. The Supreme Court must now determine whether impeachment, as currently practiced, meets the threshold the constitution demands. Legal analysts following the proceedings say the court's ruling will either reinforce or substantially revise the tools available to parliamentarians seeking to remove executive officers.
The Impeachment and Its Aftermath
The Senate voted in October 2024 to remove Gachagua from office following allegations of corruption, abuse of office, and undermining of state security. The charges emerged after months of public tension between Gachagua and President William Ruto, tension that had spilled into visible factional disputes within the Kenya Kwanza administration. The removal was historic — no deputy president had previously been successfully impeached under the 2010 constitution. But the legal basis for that removal is precisely what the Supreme Court is now scrutinising.
Following his Senate removal, Gachagua faced parallel criminal proceedings. In April 2026, he was acquitted on the most serious charges, a development his legal team characterises as corroborating their central claim: that the impeachment was politically motivated rather than grounded in legally sustainable allegations. The acquittal does not automatically undo the impeachment, however, which is why the constitutional challenge now before the Supreme Court carries such weight. The court must decide whether a legislative act of removal can stand independently of the criminal justice outcome, and whether the procedures that led to that act comported with constitutional requirements.
What the Court Must Decide
At the centre of the legal arguments is the question of what constitutes sufficient grounds for impeachment under Article 150 of the constitution. The provision requires that a deputy president be removed on grounds of gross misconduct, violation of the constitution, or physical or mental incapacity. Gachagua's lawyers contend that the Senate applied an interpretation of "gross misconduct" that stretched beyond any established precedent, and that their client was denied the opportunity to cross-examine witnesses or present a full defence before the upper house voted.
The Office of the Director of Public Prosecutions and the Senate have maintained that the impeachment process is a political rather than criminal mechanism, and that the Senate's interpretation of its constitutional role should be afforded deference. This framing — that impeachment is fundamentally a parliamentary prerogative — is what Gachagua's team is asking the Supreme Court to reject. If the court agrees that constitutional protections apply with full force to impeachment proceedings, future attempts to remove senior executive officers will face significantly higher procedural hurdles.
A Constitution Under the Microscope
Kenya's 2010 constitution was drafted in the aftermath of the 2007-08 post-election violence, a crisis that exposed the dangers of concentrating executive power without adequate checks. The document created new institutions — including the Supreme Court itself, the Independent Electoral and Political Processes Directorate, and strengthened Chapter Six provisions on leadership and integrity — to prevent any single figure from accumulating unchecked authority. The Gachagua case tests whether those institutional safeguards function as intended when the political will to deploy them aligns with institutional ambition.
Critics of the current government argue that the impeachment was precisely the kind of executive overreach the constitution was designed to prevent — a ruling coalition using parliamentary majorities to eliminate a political rival rather than a genuine accountability mechanism. Supporters of the Ruto administration counter that the allegations against Gachagua were substantively warranted and that the Senate fulfilled its constitutional oversight function. The Supreme Court's ruling will not settle the political argument, but it will establish the legal parameters within which such arguments can legitimately be conducted.
The implications extend beyond Kenya's borders. Across East Africa, several countries — Tanzania, Uganda, Rwanda — maintain constitutional structures that concentrate significant power in executive hands, with weaker independent oversight mechanisms. A ruling from Nairobi that reinforces judicial checks on parliamentary removal processes would provide a reference point for opposition politicians, civil society advocates, and reform-minded legal practitioners throughout the region. Conversely, a ruling that defers to legislative discretion would signal that even Kenya's much-cited constitutional innovations carry limits when political stakes are sufficiently high.
What We Verified / What We Could Not
Monexus confirmed the following from publicly available reporting: that the Supreme Court hearing took place on 22 May 2026; that Gachagua was removed by the Senate in October 2024; that he was acquitted on criminal charges in April 2026; and that his legal challenge centres on the procedural adequacy of the impeachment process. We were unable to independently verify the specific procedural claims made by Gachagua's legal team — such as which witnesses he was prevented from cross-examining or the exact timeline of Senate committee proceedings — because those details have not been fully reported in the sources accessible to this publication. The substantive content of the charges, as described by the Senate in October 2024 reporting, is stated as it appeared in that coverage without independent verification of the underlying allegations.
Stakes and Forward View
If the Supreme Court rules in Gachagua's favour, the Senate's impeachment would be voided, potentially reopening questions about the legitimacy of the current executive composition and the political arrangements within the Kenya Kwanza coalition. If the court upholds the impeachment, it will have endorsed a broad interpretation of parliamentary power to remove executive officers — one that opposition politicians throughout the region will cite as evidence that constitutional text offers limited protection when ruling coalitions are sufficiently unified.
The court has indicated it will deliver its judgment before the end of the current term. Whatever the ruling, it will reshape how Kenya's constitution is read, cited, and relied upon — by lawyers, by politicians, and by citizens who have watched the past two years unfold as a slow-motion test of institutional resilience.
