Conditional, revocable, premature release of a prisoner. Commonly, prisoners serving sentences from one to four years are eligible for parole after serving one third of the sentence, subject to a minimum of one year. Some jurisdictions (such as the US) allow parole even to those serving life sentence. In most cases, it is granted by a local parole board in consultation with members of the community. A 19th century US invention, parole is not remission of a sentence. If the released convict (called the parolee) breaks any condition of the release, he or she may be arrested again to serve the remaining portion of the sentence in prison. In comparison, a probation is granted usually before the convict begins serving the sentence.
