As tribune in 137 bc passed a law extending voting by ballot to trials before the assembly, except for treason. He was consul 127 and censor 125. Renowned for severity as a iudex (called ‘scopulus reōrum’, the rock on which the guilty foundered), he gained fame by formulating the question ‘Cui bonō?’ (‘Who profited?’) as a principle of criminal investigation. In 113, when three Vestals had been accused of unchastity and two acquitted by the pontifex maximus, he was appointed a special investigator and condemned them and some men involved.
