Congressional and legislative plans are enacted by the Texas State Legislature, subject to the Governor’s veto. If they fail to enact legislative plans, authority passes to the Legislative Redistricting Board of Texas, a 5-member politician commission.
Texas’ congressional delegation grew from 36 seats to 38 (a gain of 2 seats) following the 2020 reapportionment.
Primary Authority: Congressional plans are enacted by the Texas State Legislature, subject to the Governor’s veto. The Legislature can override a veto with a 2/3 vote in each chamber. No party currently has a veto-proof majority in either chamber.
If a bill is presented to the governor during session, the governor has 10 days to sign or veto it; otherwise, it becomes law without signature. If the bill is delivered to the governor within 10 days of adjournment, the governor must sign or veto it within 20 days of session adjournment; otherwise, it becomes law. Sundays are excluded from these calculations.
