Article XI, Section 3 | Requirements for drawing House of Representatives districts

(A) The whole population of the state, as determined by the federal decennial census or, if such is unavailable, such other basis as the general assembly may direct, shall be divided by the number "ninety-nine" and by the number "thirty-three" and the quotients shall be the ratio of representation in the house of representatives and in the senate, respectively, for ten years next succeeding such redistricting.

(B) A general assembly district plan shall comply with all of the requirements of division (B) of this section.

(1) The population of each house of representatives district shall be substantially equal to the ratio of representation in the house of representatives, and the population of each senate district shall be substantially equal to the ratio of representation in the senate, as provided in division (A) of this section. In no event shall any district contain a population of less than ninety-five per cent nor more than one hundred five per cent of the applicable ratio of representation.

(2) Any general assembly district plan adopted by the commission shall comply with all applicable provisions of the constitutions of Ohio and the United States and of federal law.

(3) Every general assembly district shall be composed of contiguous territory, and the boundary of each district shall be a single nonintersecting continuous line.

(C) House of representatives districts shall be created and numbered in the following order of priority, to the extent that such order is consistent with the foregoing standards:

(1) Proceeding in succession from the largest to the smallest, each county containing population greater than one hundred five per cent of the ratio of representation in the house of representatives shall be divided into as many house of representatives districts as it has whole ratios of representation. Any fraction of the population in excess of a whole ratio shall be a part of only one adjoining house of representatives district.

(2) Each county containing population of not less than ninety-five per cent of the ratio of representation in the house of representatives nor more than one hundred five per cent of the ratio shall be designated a representative district.

(3) The remaining territory of the state shall be divided into representative districts by combining the areas of counties, municipal corporations, and townships. Where feasible, no county shall be split more than once.

(D)(1)(a) Except as otherwise provided in divisions (D)(1)(b) and (c) of this section, a county, municipal corporation, or township is considered to be split if any contiguous portion of its territory is not contained entirely within one district.

(b) If a municipal corporation or township has territory in more than one county, the contiguous portion of that municipal corporation or township that lies in each county shall be considered to be a separate municipal corporation or township for the purposes of this section.

(c) If a municipal corporation or township that is located in a county that contains a municipal corporation or township that has a population of more than one ratio of representation is split for the purpose of complying with division (E)(1)(a) or (b) of this section, each portion of that municipal corporation or township shall be considered to be a separate municipal corporation or township for the purposes of this section.

(2) Representative districts shall be drawn so as to split the smallest possible number of municipal corporations and townships whose contiguous portions contain a population of more than fifty per cent, but less than one hundred per cent, of one ratio of representation.

(3) Where the requirements of divisions (B), (C), and (D) of this section cannot feasibly be attained by forming a representative district from whole municipal corporations and townships, not more than one municipal corporation or township may be split per representative district.

(E)(1) If it is not possible for the commission to comply with all of the requirements of divisions (B), (C), and (D) of this section in drawing a particular representative district, the commission shall take the first action listed below that makes it possible for the commission to draw that district:

(a) Notwithstanding division (D)(3) of this section, the commission shall create the district by splitting two municipal corporations or townships whose contiguous portions do not contain a population of more than fifty per cent, but less than one hundred per cent, of one ratio of representation.

(b) Notwithstanding division (D)(2) of this section, the commission shall create the district by splitting a municipal corporation or township whose contiguous portions contain a population of more than fifty per cent, but less than one hundred per cent, of one ratio of representation.

(c) Notwithstanding division (C)(2) of this section, the commission shall create the district by splitting, once, a single county that contains a population of not less than ninety-five per cent of the ratio of representation, but not more than one hundred five per cent of the ratio of representation.

(d) Notwithstanding division (C)(1) of this section, the commission shall create the district by including in two districts portions of the territory that remains after a county that contains a population of more than one hundred five per cent of the ratio of representation has been divided into as many house of representatives districts as it has whole ratios of representation.

(2) If the commission takes an action under division (E)(1) of this section, the commission shall include in the general assembly district plan a statement explaining which action the commission took under that division and the reason the commission took that action.

(3) If the commission complies with divisions (E)(1) and (2) of this section in drawing a district, the commission shall not be considered to have violated division (C)(1), (C)(2), (D)(2), or (D)(3) of this section, as applicable, in drawing that district, for the purpose of an analysis under division (D) of Section 9 of this article.
