The U.S. Supreme Court announced Thursday that it has agreed to hear a case next term that could upend election laws across the country with the potential endorsement of a fringe legal theory about how much power state legislatures have over the running of congressional and presidential elections.

The case, called Moore v. Harper, is centered on newly drawn maps of voting districts for North Carolina's 14 seats in the next U.S. House of Representatives.
