This image summarizes the steps through which a proposed law--a bill--must move to become law in Texas. A bill is introduced separately in each chamber and read for the first time. Each chamber's presiding officer (Speaker or Lieutenant Governor) assigns the bill to a committee which studies the bill and decides whether to hold hearings. The committee issues a favorable or unfavorable report. In the House it's then sent to the Calendars Committee which schedules consideration of bills. In the Senate, a bill must receive 2/3 vote of the Senate to bring it to the full Senate for discussion. If a bill reaches the stage of discussion by the full membership of each chamber it is given a second reading, debated, amended, and subject to membership wishes passed to a third reading and another round of debate and amendment before a final vote is taken. If a bill passes the House and then the Senate but the Senate makes changes the House must approve Senate changes or the House and Senate must resolve their differences via a conference committee. And changes made by a conference committee must be approved by both chambers before a bill is enrolled (designated as having passed), signed by the presiding officers of both chambers and sent to the Governor. The Governor then signs, refuses to sign, or vetoes the bill. The bill becomes law with or without the Governor's signature but a vetoe by the Governor blocks a bill from becoming law unless the Legislature votes to override the veto by a 2/3 vote of each chamber.
