The impeachment of a deputy president in Kenya, such as Rigathi Gachagua, could potentially be challenged in court, but the court’s ability to overturn it would depend on the specific legal grounds raised.

The Constitution of Kenya outlines a specific process for the impeachment of a Deputy President. According to Article 150, the Deputy President can be impeached on grounds of gross violation of the Constitution or any other law, where there is serious reason to believe that they have committed a crime under national or international law, or for gross misconduct.

If the National Assembly and Senate follow the constitutional process properly, including a thorough investigation and a two-thirds majority vote in both houses, it becomes very difficult for the courts to interfere. However, if procedural irregularities or violations of constitutional rights are proven, the court could step in to review and potentially overturn the impeachment.

In short, while it’s possible for the court to review an impeachment process, an actual overturning would depend on the presence of legal errors or violations.
