Finally through Curio, he caused his ultimatum to be read in the senate on January 1. He demanded as a right the privilege of running for the consulship while proconsul, and he declared his willingness to resign at the same time as Pompeius; in any other case he would be compelled to vindicate his rights. The fact that Curio was accompanied by one of Caesar's officers made the threat of war plain enough.

The tribunes Mark Antony and Q. Cassius Longinus, who were the agents of Caesar, interceded and legally annulled the decree. Discussion with these tribunes led to no results, and the senate therefore on January 7 declared martial law (by the senatus consultum ultimum), and authorized the consuls, the praetors, the proconsuls outside the city, and the loyal tribunes in case of necessity to use force against the interceding tribunes.
