There are approximately eight lawsuits against the Texas U.S. House and state legislative district boundaries, mostly in federal court. But from the filings so far, it appears the plaintiffs will not seek a postponement of the March 2022 primary. Instead, if they prevail, they will probably depend on past Texas precedents when the boundaries of many districts changed after that year’s primary was over. In those cases, the primary results for the districts whose boundaries changed were set aside. Instead, candidate filing re-opened in those districts, and the winners were determined in November as though they were special elections. In Texas special elections, there are no party nominees. Everyone runs in the election, and if no one gets 50%, there is a run-off.
In 1996 in Texas, 13 of the U.S. House districts (out of 30 districts) used the special election procedures. The boundaries of the 1990’s districts had been changed after the 1996 primary by a federal court. Someone got over 50% in November in most of those districts. In the three districts in which no one got 50% in November, there was a run-off on December 10, 1996. Thanks to Jim Riley for this news.
