Texas Election Code - ELEC § 232.013. Rescheduling Runoff for Contested Race

(a) If the final judgment in an election contest necessitates a runoff election in the contested race, the district judge shall set the date for the runoff if the judge determines that lack of time prevents the proper conduct of the runoff on the regularly scheduled date. The runoff must be held on the same day of the week as the regularly scheduled runoff.

(b) The date set for the runoff may not provide a longer interval between the court order and the runoff than is required or authorized by law between the main election and a regularly scheduled runoff. The date may provide a shorter interval, but the interval must make it possible for early voting by personal appearance to begin not later than the 10th day before election day.

(c) If the runoff is set for a date that shortens the regular period for early voting, the order setting the date of the election must specify the date for beginning early voting by personal appearance.

(d) If the contested election is a primary, the district clerk shall deliver a certified copy of the order setting the date of the runoff to the state chair of the political party in the case of a statewide or district office or to the county chair in the case of a county or precinct office.
