High Court Hears Challenge to Rigathi Gachagua’s Impeachment: Process, Power, and Political Stakes

Kenya’s High Court is now the centre of a constitutional fight over the impeachment of former Deputy President Rigathi Gachagua—the first such removal in Kenya’s history and a major test of judicial control over political accountability.[1][2] This article focuses on Kenyan law and institutions only and is for general information; it is not legal advice.

From Senate Ouster to High Court: How the Gachagua Impeachment Landed Back in Court

In 2024, the Senate voted to remove Gachagua on five of 11 charges, including ethnic balkanization and undermining the judiciary, the first impeachment of a Deputy President under the 2010 Constitution.[1][2] The vote followed a sharply polarized climate and heavy media scrutiny.

Under the Constitution, impeachment proceeds as follows:[4]

• National Assembly:

  • Receives and debates a motion
  • Conducts or mandates investigations
  • Decides whether to forward charges to the Senate

• Senate:

  • Sits as a trial body
  • Determines whether the threshold of “gross violation” or “gross misconduct” is met

Gachagua’s lawyers say these steps were rushed and constitutionally flawed, citing violations of fair administrative action and due process.[2][4] They argue:

• Public participation was perfunctory and too rushed for meaningful citizen input
• Hearings became a partisan spectacle, not an impartial inquiry[2][4]

After removal, Gachagua moved to the High Court challenging both legality and constitutionality of the process.[4] Earlier, he had tried to stop the impeachment at the Supreme Court, claiming Parliament’s ongoing proceedings violated his rights.[5]

• A bench led by Deputy Chief Justice Philomena Mwilu declined jurisdiction, holding that:
  • The High Court is the proper forum for such disputes
  • Parallel applications by Gachagua and the National Assembly should be struck out[5]

That decision cleared the way for the current, merits‑based High Court challenge.

💡 Key takeaway: Impeachment in Kenya is both political and subject to judicial review; the exact limits of that review are now being tested.[4][5]

Inside the High Court Hearing: Key Arguments, Bench Dynamics, and Procedural Flashpoints

The main petition is before a three‑judge bench at the Milimani Law Courts—Erick Ogolla, Anthony Mrima, and Dr. Freda Mugambi—empanelled by the Supreme Court.[2][4] Gachagua has attended in person, often with his spouse Dorcas Rigathi and a senior legal team led by Paul Muite.[2][4]

His lawyers portray the impeachment as a politically driven “hit‑job” that breached natural justice:[2]

• Timelines allegedly too compressed for proper public participation
• Inadequate disclosure of evidence before hearings
• Limited chance to cross‑examine witnesses or respond to late evidence[2][4]

They further argue:[2][4]

• The Senate treated Article 145’s threshold as political discretion, not a legal standard
• It acted as a “conveyor belt” for the Executive, not an independent trial body

For the bench, key questions include:[4]

• Scope of judicial review over Parliament’s impeachment powers without violating separation of powers
• Evidentiary and procedural thresholds for removing a Deputy President
• When speed and political pressure cross into constitutional violations

An added issue is Gachagua’s alleged ill‑health during Senate hearings, supported by medical testimony attributed in media reports to Dr. Dan Gikonyo.[3] Commentators note that:[3]

• Proven serious illness could affect:
  • Whether notice was effective
  • Whether he could meaningfully participate or instruct counsel

Judges must sift genuine constitutional claims from political grievances.[3]

⚠️ Key point: The High Court is not re‑trying the charges; it is testing whether the Senate process and threshold complied with the Constitution and the Bill of Rights.[2][4]

What’s at Stake: Constitutional Precedent, Political Fallout, and Public Perception

The ruling could reset the balance between Parliament and Judiciary in impeachment matters:[4]

• Upholding Parliament:

  • Signals strong deference to political judgment
  • Keeps impeachment primarily a political remedy with limited review[4]

• Finding defects:

  • Expands judicial oversight over impeachment
  • Forces stricter procedures, better records, and clearer standards on participation and fair hearing[2][4]

If the impeachment is invalidated, analysts warn of a potential constitutional crisis because Kithure Kindiki currently holds the office:[2]

• Could Gachagua be reinstated, and how quickly?
• What happens to appointments and decisions made by the current Deputy President?
• Would the court delay its orders to allow political and institutional adjustment?

Politically, the case affects:[1][2]

• Power balances within the ruling coalition and opposition
• Gachagua’s national standing—revival if he wins, marginalization if he loses
• The Executive’s interests, signalled by President William Ruto’s earlier objection to the High Court’s jurisdiction[1]

Public engagement has been intense:[6][7]

• Live broadcasts and social media coverage frame the case as:
  • A test of rule of law and elite accountability
  • A contest over whether impeachment is genuine oversight or political revenge[6][7]

📊 Public lens: Non‑stop coverage and partisan narratives heighten pressure for clear, well‑reasoned judicial explanations.[6][7]

Conclusion: Why This Case Matters for Kenya’s Constitutional Future

The Gachagua challenge lies at the intersection of constitutional design and high‑stakes politics.[2][4] It will clarify:

• How resilient Kenya’s impeachment framework is against partisan misuse
• What fair process, real public participation, and health‑related constraints mean in high‑office removals[3][4]

Most crucially, the ruling may set binding precedent on:[2][4]

• The legal status of an impeached Deputy President
• The legitimacy and continuity of their successor

⚡ Call to action: As hearings and judgments unfold, attention should centre on legal principles, institutional checks, and long‑term democratic norms—not only on partisan winners and losers.
