With the deadline to file for reelection a little over a month away, two of Utah’s Republican members of Congress are asking a federal court to block the use of new U.S. House districts that could significantly boost Democrats’ chances of winning a Salt Lake City area seat in November.

A lawsuit filed late Monday by U.S. Reps. Celeste Maloy and Burgess Owens and nearly a dozen local officials contends a state judge violated the U.S. Constitution last year when she rejected congressional districts drawn by the Republican-led state Legislature and instead imposed an alternative map submitted by groups suing the Legislature.

The U.S. Constitution and Utah Constitution both give redistricting powers to the state Legislature, the lawsuit asserts, and “courts have no authority to draw a congressional map.” The lawsuit contends Utah’s districts should revert to those last approved by the Legislature in 2021, unless lawmakers come up with new ones.

Utah is one of several states still locked in legal battles over House voting districts ahead of the midterm elections this fall.
