The Oregon Supreme Court ruled Thursday that 10 Republican state senators are prohibited from running for reelection after participating in the longest walkout in state history, making one-third of the chamber ineligible for reelection.

Last year’s six-week walkout was an effort to boycott Democratic-proposed bills on abortion, transgender healthcare, and gun control that the GOP lawmakers opposed. Senate President Rob Wagner did not excuse the senators’ absences due to a 2022 voter-approved measure that banned lawmakers from reelection if they racked up more than 10 unexcused absences. Under the measure, the secretary of state barred the senators from the ballot.
