 The Assembly is headed by the Speaker; the Senate is headed by the President, a post held "ex officio" by the Lieutenant Governor, who only has a tie-breaking "casting vote", but more often it is presided over by the Temporary President or by a senator of the Majority Leader's choosing.The Legislature is empowered to make laws, subject to the Governor's power to veto a bill.However, the veto may be overridden by the Legislature if there is a two-thirds majority in favor of overriding in each House.
