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.

Then out of compassion, leniency, plea bargaining or the fact that the several crimes are interrelated, the judge will rule that the sentences may all be served at the same time, with the longest period controlling.
