 Next, in this series of pardoning powers is commute or commutation. It is the process of substitution or replacement of one form of punishment for a lighter form. I will tell you a trick to remember the definition. What is the literal meaning of commute? It means to travel to work. So you are travelling from home to work, meaning you are travelling from one place to another. Likewise, commute and quality means changing the punishment from one form to the other. But the key point here is that it changes the punishment to a lighter form. Examples include commutation of a death sentence to rigorous imprisonment and this rigorous imprisonment can be commuted to simple imprisonment. See, President can commute the sentences of court martial, punishment under union law and death sentence. But Governor can commute only punishments given under state law and the death sentence. He does not have any power regarding sentences of court martial. Thank you.
