The Washington Redistricting Commission is a decennial body charged with redrawing congressional and legislative districts in the state of Washington after each census. On November 8, 1983, Washington state passed the 74th amendment to its constitution via Senate Joint Resolution 103 to permanently establish the Redistricting Commission. Earlier that year the first commission redrew the state's congressional map after the previous one drawn by the legislature was ruled unconstitutional. Since after the 1990 Census, a committee of four appointees of the majority and minority leaders of the House and Senate appoint a fifth member as non-voting chair, and meet to redistributes representative seats according to census results.
