 Remission is one of the five clemency powers that is available to both the president and the governor. Remission means reduction. In case of remission, there is a reduction in the time period of sentence without any change in the nature of a sentence. For example, a person undergoing 10 years of rigorous imprisonment after remission will undergo only 5 years of rigorous imprisonment. Here, there is no change in the nature of sentence but only reduction in the time period of sentence. To remember the difference between commutation and remission, associate the word commutation with the word change because in case of commutation, there is a change in the nature of a sentence. Also, commutation and change start with the same letter C and associate the word remission with reduction because both words start with the same letter R and there is only a reduction in the time period of sentence.
