Concurrent

Concurrent, acting in conjunction; agreeing in the same act; contributing to the same event; contemporaneous. As to concurrent writs of summons, which are used for service abroad, etc., and of which a plaintiff can have on payment as many as he pleases, see R.S.C., 1883, Ord. VI. Concurrent sentences, if newly passed, can always be given, but a sentence cannot be given to a prisoner convicted whilst out on ticket of leave to run concurrently with his unexpired sentence; per Hawkins, J., in R. v. King, (1897) 1 QB 218.
