Tex. Elec. Code § 213.057
As soon as practicable after completion of a recount that changes the number of votes received for a particular candidate or for or against a measure, the final canvassing authority shall conduct a canvass for the office or measure involved using the recount supervisor's report, instead of the original county election returns, for each county in which a recount was conducted. An original final canvass for the office or measure is void, and the new final canvass is the official final canvass for the election on that office or measure. If no change occurs in the recount in the number of votes received for a candidate or for or against a measure, the official result of the election is determined from the original final canvass.
