If there is a vacancy in the Oregon State Legislature, the board of county commissioners representing the vacant seat must select a replacement. This can only be done when the Legislature is in session or when the vacancy happens more than 61 days before the next scheduled general election.^[5] The board must select a person from the political party that last held the vacant seat. The board must consider three to five candidates, nominated by the local county party that last controlled the seat. A replacement must be selected within 30 days of the vacancy.

Gov. Kate Brown (D) signed new state legislative maps into law on September 27, 2021. The maps were approved by the Oregon House of Representatives, 31-18, and approved in the Oregon State Senate 18-11.^[7] These maps took effect for Oregon’s 2022 legislative elections.

How does redistricting in Oregon work? In Oregon, congressional and state legislative district lines are drawn by the state legislature. District lines are subject to veto by the governor.^[8]

If the legislature fails to establish a redistricting plan for state legislative districts, it falls to the secretary of state to draw the boundaries.^[8]

State law requires that congressional and state legislative districts meet the following criteria:^[8]

Districts must be contiguous.
Districts must "utilize existing geographic or political boundaries."
Districts should not "divide communities of common interest."
Districts should "be connected by transportation links."
Districts "must not be drawn for the purpose of favoring a political party, incumbent or other person."
