The
Lex Titia was a
Roman law passed on November 27, 43 BC, that legalized the
Second Triumvirate of
Octavian,
Mark Antony, and
Marcus Aemilius Lepidus. The
Lex Titia gave this "three-man commission for restoring the constitution of the republic" (
triumviri rei publicae constituendae) the power to make or annul laws without approval from either the
Senate or the people; insulated their judicial decisions from appeal, and allowed the Triumvirs to name
magistrates at will. Although the constitutional machinery of the
Republic was not irrevocably dismantled by the
Lex Titia, in the event it never recovered. Lepidus was sidelined early in the triumvirate, and Antony was eliminated in civil war, leaving Octavian the sole leader.
