The Latest

Congress: On September 21, the state legislature passed HB 319, which was signed on September 26. The law purported to limit the opportunity to file a referendum on the maps, but on October 14, the Ohio Supreme Court unanimously allowed the possibility of a referendum to the plan, with signatures (from 6% of the state's electors) due by December 25. On December 14, the state legislature passed HB 369, a revised congressional plan, which was signed by the governor on December 15.

State leg.: On September 28, the politician commission passed state Senate and state House lines, on a partisan vote. Challenges to the plan were defeated in the courts.

A voter initiative to change the redistricting process for 2021 qualified for the November 2012 ballot; there was litigation over the ballot language, and a complaint before the Ohio Elections Commission regarding allegedly false statements in a campaign flyer with respect to the measure. The measure was ultimately defeated in the 2012 general election.

On December 17, 2014, the legislature passed a state constitutional amendment, which would revise the redistricting process and criteria for 2020 and beyond; the measure will be submitted to voters in 2015. The amendment would expand the existing body for drawing state lines: the current three statewide officials, and a designee of the majority and minority leader of each state legislative chamber. The map will be valid for the decade if passed with the votes of at least two members of each major party; if passed by a partisan majority, the map will be valid for only four years. The plan retains, and tightens, the priority placed on not splitting counties or towns between districts. To the extent those constraints leave options, the plan may not be drawn primarily to favor or disfavor a party, and the plan must attempt to draw lines so that the partisan leaning of districts roughly echoes the electorate's statewide partisan preferences.

  • Institution

    Redistricting political control:

    Governor State Senate State House
    Congressional lines R 10 D, 23 R 40 D, 59 R
    State legislative lines Governor, Auditor, Secretary of State, R designee, D designee
    2000 cong. lines R 11 D, 21 R 39 D, 59 R
    2000 state lines Governor, Auditor, Secretary of State, R designee, D designee

    Ohio's congressional lines are drawn by the state legislature, as a regular statute, subject to gubernatorial veto. The members of the state House redistricting committee are listed here; the members of the state Senate committee are listed here.

    Ohio's state legislative lines are drawn by a five-member politician commission, in place since 1967. The commission consists of the Governor, Auditor, Secretary of State, one commissioner chosen by the speaker of the House in concert with his party's leader in the Senate; and the other chosen by the House minority leader along with his party's leader in the Senate. The members of the commission are listed here. [Ohio Const. art. XI, § 1]

    Both processes are aided by a 6-member advisory commission. The state Senate and state House majority leaders each appoint three members, at least one of whom must be from a different party, and at least one of whom must not be a legislator. [Ohio Rev. Code § 103.51]

    Ohio law gives the Ohio Supreme Court original and exclusive jurisdiction to hear challenges to state legislative lines filed in state court; if a state legislative plan is declared invalid, the politician commission will have an opportunity to redraw legal districts. [Ohio Const. art. XI, § 13]

  • Timing

    Census data were delivered to Ohio on March 9, 2011.

    Ohio state law does not impose a particular deadline for drawing congressional lines, though candidates must file for congressional primary elections by December 7, 2011. [Ohio Rev. Code § 3513.05] The regular legislative session began on January 3, 2011, and ends December 31, 2011.

    State legislative district lines must be drawn by October 1, 2011. [Ohio Const. art. XI, § 1] Candidates must file for state legislative primary elections by December 7, 2011. [Ohio Rev. Code § 3513.05]

    Ohio law prohibits redrawing state legislative districts mid-decade, before the next Census; there is no similar provision pertaining to congressional lines. [Ohio Const. art. XI, § 6]

  • Public input

    The legislative committees responsible for congressional redistricting, and the politician commission responsible for state legislative redistricting, conducted hearings trhough the summer. Minutes and materials for congressional redistricting are archived here, and minutes and materials for state legislative redistricting are archived here.

    The Secretary of State's office has made available a version of Maptitude Online for citizens to draw and submit their own district plans.

  • Criteria

    Like all states, Ohio must comply with constitutional equal population requirements, and with section 2 of the Voting Rights Act.

    Ohio law further requires that state legislative districts be contiguous and compact. Districts must preserve whole political units -- counties, townships, municipalities, and wards, in that order -- where feasible. For counties sufficiently populous to contain entire legislative districts, such districts must be created wholly within the county, and any remaining territory in the county must be contained in only one legislative district. Where it is not possible to preserve political units whole, only one political unit may be divided between two legislative districts. [Ohio Const. art. XI, §§ 7, 9]

    State House districts must be nested within state Senate districts, so that each Senate district is made up of three House districts. [Ohio Const. art. XI, § 11]

    State ex rel. Ohioans for Fair Districts v. Husted, No. 2011-1646 (Ohio Sup Ct.): a challenge in state court to the law containing the congressional plan, which purports to limit the ability to submit the plan to a referendum, as other state laws are subject to referendum.
