Life imprisonment

Life imprisonment is a term used for a particular kind of sentence of imprisonment. The effect of such a sentence varies between jurisdictions; many nations have a maximum possible period of time a prisoner may be incarcerated, or require the possibility of parole after a set amount of time.

Interpretation in North America

• In the United States, life imprisonment usually lasts until the prisoner dies. Sometimes life terms are given in sentences that are intentionally longer than how long the prisoner is expected to live, e.g. a 200-year sentence for multiple counts of murder. In actuality, a life sentence does not always mean "imprisonment for life." In many states, a convict can be released on parole after a decade or more has passed. For example, sentences of "15 years to life" or "25 years to life" may be given. Even when a sentence specifically denies the possibility of parole, government officials may have the power to grant amnesty or reprieves, or commute a sentence to time served. Under the federal criminal code, however, with respect to offenses committed after December 1, 1987, parole has been abolished for all sentences handed down by the federal system, including life sentences, so a life sentence from a federal court will result in imprisonment for the life of the defendant, unless a pardon or reprieve is granted by the President.
