Gabinian Law, in Roman history, a name given to two distinct laws passed by the Senate. 1. A law, passed in 67 B. C., investing Pompey with unlimited command for the space of three years over the Mediterranean and its coasts for fifty miles inland. He was given control also of the public treasure of the provinces. Under authority of this law, Pompey cleared the Mediterranean of pirates. 2. A Roman law, passed 58 B.
