 Within days of Antony's expulsion, on 7 January 49 BC, the senate reconvened.Under the leadership of Cato and with the tacit support of Pompey, the senate passed a "senatus consultum ultimum", a decree stripping Caesar of his command and ordering him to return to Rome and stand trial for war crimes.The senate further declared Caesar a traitor and a public enemy if he did not immediately disband his army.
