In law, a sentence forms the final act of a judge-ruled process, and also the symbolic principal act connected to his function. The sentence generally involves a decree of imprisonment, a fine and/or other punishments against a defendant convicted of a crime. Those imprisoned for multiple crimes, will serve either a consecutive sentence (in which the period of imprisonment equals the sum of all the sentences) or a concurrent sentence (in which the period of imprisonment equals the length of the longest sentence). If a sentence gets reduced to a less harsh punishment, then the sentence is said to have been "mitigated". Rarely (depending on circumstances) murder charges are "mitigated" and reduced to manslaughter charges. However, in certain legal systems, a defendant may be punished beyond the terms of the sentence, e.g. social stigma, loss of governmental benefits, or collectively, the collateral consequences of criminal charges.
