Impeachment is a political process where charges are levelled against governors or their deputies for violation of the Constitution or abuse of office. Impeachment does not equate to criminal offence per se, that is dealt with at the judicial courts. The standard of proof and the method used to adduce evidence is different. Someone could be impeached and found guilty and if the same charges and evidence taken through the criminal system, there could be a different outcome. It is rather the cleansing of the office where the holder has brought disrepute and shame.
When the people of Kenya decided to have the devolved system of governance, those who play small gods in the West and the Bretton Woods institutions wrote off the idea and said it will fail.
