Mathenge and Kamotho were among litigants who moved to court to challenge the impeachment process alongside Gachagua who filed his case at Milimani High Court.
Others who also filed separate cases are Father Eddie Waiguru, Anthony Mwithaga, Victor Ngatia, Gema Watho, Peter Kimani and Alice Wamuhu. There are a total of 32 petitioners in Fr Waiguru's case.
Their grievance was that President William Ruto had conspired with Parliament to kick out Gachagua owing to his sentiments on the ills committed by the Kenya Kwanza government during the Finance Act 2024 protests.
According to them, Ruto is on a quest to find a person who is agreeable to the problems faced by the current administration.
Then there was lawyer Elijah Otieno who also filed another case.
Otieno argued that impeaching Gachagua from office was an act of political deceit, vendetta and betrayal against him and the people of the Mount Kenya region.
According to him, the move by Parliament was too fatal to Gachagua as it sent him to political oblivion without hearing him.
"The irreparable consequences of a successful impeachment motion of a President or Deputy President of the Republic of Kenya is that the holder of the office is permanently barred from holding any public office and therefore great care ought to be taken to ensure legal and constitutional compliance to the hilt in the processing of a motion of such a nature," argued Otieno.
From all the petitions filed yesterday, the issues raised ranged from the evidence submitted by Kibwezi West Member of Parliament Mwengi Mutuse, the Speaker of National Assembly's sentiments in favour of impeachment, and the Senate's failure to adjourn to accommodate Gachagua after he fell ill.
