It is widely acknowledged that the concentration of all types of state power into the same hands can lead to iniquitous and/or inefficient government. In the famous words of the British historian, Lord Acton: 'Power tends to corrupt; absolute power corrupts absolutely.' Constitutional theorists argue that for a constitution to be 'efficient' and 'well arranged' the three branches (or organs) of state (the judiciary, executive and legislature) should be separated into different bodies or persons.
