Struggle to Establish a Consistent Standard of Review in Ballot Access Cases Continues”, see 77 Den. U. L. Rev. 197 (1999). Annotator’s note. The following annotations include cases decided under former provisions similar to this section. The requirement that petitions be circulated within a six-month period is not an unreasonable burden on the rights of either the proponents of the petition or of the voting public. Am. Constitutional Law . The six-month deadline set forth in subsection (1) is a reasonable, nondiscriminatory ballot access regulation; it does not offend the first and fourteenth amendments of the United States Constitution. The requirement preserves the integrity of the state’s elections,
maintains an orderly ballot, and limits voter confusion. The requirement advances those interests by establishing a reasonable window in which proponents must demonstrate
support for their causes. Am. Constitutional Law Found.,
Inc. v. Meyer, 120 F.3d 1092 (10th Cir. 1997), aff’d on
Rule 17.3.8 Date of signing.
a. If a signature is placed on the petition prior to the final approval of the petition format by the designated election official, the entry shall be rejected.
Also you’ll see on the “Initiative Spreadsheet” pages 16-18, that no other action has taken place on early title settings. http://www.sos.state.co.us/pubs/elections/Initiatives/InitiativesHome.html
