Effective - 28 Aug 2014   115.237. Ballots, contents of — straight political party ticket voting prohibited — rulemaking authority. — 1. Each ballot printed or designed for use with an electronic voting system for any election pursuant to this chapter shall contain all questions and the names of all offices and candidates certified or filed pursuant to this chapter and no other. As far as practicable, all questions and the names of all offices and candidates for which each voter is entitled to vote shall be printed on one page except for the ballot for political party committee persons in polling places not utilizing an electronic voting system which may be printed separately and in conformity with the requirements contained in this section. As far as practicable, ballots containing only questions and the names of nonpartisan offices and candidates shall be printed in accordance with the provisions of this section, except that the ballot information may be listed in vertical or horizontal rows. The names of candidates for each office shall be listed in the order in which they are filed.  2. In polling places using electronic voting systems, the ballot information may be arranged in vertical or horizontal rows or on a number of separate pages or screens. In any event, the name of each candidate, the candidate's party, the office for which he or she is a candidate, and each question shall be indicated clearly on the ballot.  3. Nothing in this subchapter shall be construed as prohibiting the use of a separate paper ballot for questions or for the presidential preference primary in any polling place using an electronic voting system.  4. Where electronic voting systems are used and when write-in votes are authorized by law, a write-in ballot, which may be in the form of a separate paper ballot, card, or envelope, may be provided by the election authority to permit each voter to write in the names of persons whose names do not appear on the ballot.  5. No ballot printed or designed for use with an electronic voting system for any partisan election held under this chapter shall allow a person to vote a straight political party ticket. For purposes of this subsection, a "straight political party ticket" means voting for all of the candidates for elective office who are on the ballot representing a single political party by a single selection on the ballot.  6. The secretary of state shall promulgate rules that specify uniform standards for ballot layout for each electronic or computerized ballot counting system approved under the provisions of section 115.225 so that the ballot used with any counting system is, where possible, consistent with the intent of this section. Nothing in this section shall be construed to require the format specified in this section if it does not meet the requirements of the ballot counting system used by the election authority.  7. Any rule or portion of a rule, as that term is defined in section 536.010, that is created under the authority delegated in this section shall become effective only if it complies with and is subject to all of the provisions of chapter 536 and, if applicable, section 536.028. This section and chapter 536 are nonseverable and if any of the powers vested with the general assembly pursuant to chapter 536 to review, to delay the effective date or to disapprove and annul a rule are subsequently held unconstitutional, then the grant of rulemaking authority and any rule proposed or adopted after August 28, 2002, shall be invalid and void. ­­-------- (L. 1977 H.B. 101 § 8.101, A.L. 1979 S.B. 275, A.L. 1982 S.B. 526, A.L. 2002 S.B. 675, A.L. 2006 S.B. 1014 & 730, A.L. 2014 H.B. 1136)
