List of state legislative districts

There are 132 seats in the Ohio General Assembly. Approximately one half of the 33 seats in the Ohio State Senate are up for election every two years. All 99 seats in the Ohio House of Representatives are up for election every two years.

Due to a 2022 Ohio Supreme Court ruling, the Ohio Redistricting Commission was required to draw new state legislative maps following the 2022 elections.[1]

On September 26, 2023, the Ohio Redistricting Commission voted 6-0 (with one member absent) to adopt new state legislative maps.[2][3] On October 5, the ACLU of Ohio filed a motion on behalf of the League of Women Voters of Ohio and other plaintiffs asking the Ohio Supreme Court to invalidate the new state legislative maps on the grounds that they violated the state constitution.[4]

On November 27, the Ohio Supreme Court upheld the maps and dismissed the following cases: League of Women Voters of Ohio et al. v. Ohio Redistricting Commission et al., Bennett et al. v. Ohio Redistricting Commission et al., and Ohio Organizing Collaborative et al. v. Ohio Redistricting Commission et al.[5] Chief Justice Sharon Kennedy wrote for the majority: "The bipartisan adoption of the September 2023 plan is a changed circumstance that makes it appropriate to relinquish our continuing jurisdiction over these cases.[6]

The majority was composed of the court's four Republicans.

Justice Jennifer L. Brunner wrote a dissent on behalf of the court's other two Democrats, saying, "It is illusory to suggest that a bipartisan vote to adopt the September 2023 plan constitutes a change in circumstances that somehow diminishes our review power or renders a unanimous redistricting plan constitutionally compliant. There is nothing in Article XI, Section 6 that suggests that bipartisan agreement on a plan renders it presumptively constitutional, and we have flatly rejected that idea."[7] Click here for more information about redistricting after the 2020 census.

Redistricting

In Ohio, the state legislature or a commission may have the opportunity to draw congressional maps. A bipartisan state legislative commission draws state legislative maps. A six-member advisory commission is involved in both the congressional and state legislative redistricting processes. Due to a 2022 Ohio Supreme Court ruling, the Ohio Redistricting Commission was required to draw new state legislative maps following the 2022 elections.[20]

On September 26, 2023, the Ohio Redistricting Commission voted 6-0 (with one member absent) to adopt new state legislative maps.[21][22] On October 5, the ACLU of Ohio filed a motion on behalf of the League of Women Voters of Ohio and other plaintiffs asking the Ohio Supreme Court to invalidate the new state legislative maps on the grounds that they violated the state constitution.[23]

On November 27, the Ohio Supreme Court upheld the maps and dismissed the following cases: League of Women Voters of Ohio et al. v. Ohio Redistricting Commission et al., Bennett et al. v. Ohio Redistricting Commission et al., and Ohio Organizing Collaborative et al. v. Ohio Redistricting Commission et al.[5] Chief Justice Sharon Kennedy wrote for the majority: "The bipartisan adoption of the September 2023 plan is a changed circumstance that makes it appropriate to relinquish our continuing jurisdiction over these cases.[24]

The majority was composed of the court's four Republicans.

There is nothing in Article XI, Section 6 that suggests that bipartisan agreement on a plan renders it presumptively constitutional, and we have flatly rejected that idea."[25]
