What is Accumulative Judgment?

A second or additional judgment given against one, who has been convicted, the execution or effect of which is to commence after the first has expired; as, where a man is sentenced to an imprisonment for six months on conviction of larceny, and, afterwards he is convicted of burglary, he may be sentenced to undergo an imprisonment for the latter crime, to commence after the expiration of the first imprisonment; this is called an accumulative jufgment.
