Colorado Single-Subject Rule: Mid-Decade Redistricting Authority and Adoption of a Specific Map Are Distinct Subjects in One Initiative

Case: In the Matter of the Title, Ballot Title, and Submission Clause for Proposed Initiative 2025-2026 #240 & In the Matter of the Title, Ballot Title, and Submission Clause for Proposed Initiative 2025-2026 #327, 2026 CO 57 (Colo. June 29, 2026)

Court: Colorado Supreme Court (en banc)  |  Posture: Original proceedings under § 1-40-107(2), C.R.S. (2025), review of Title Board actions  |  Disposition: Title Board Action Reversed

I. Introduction

This consolidated Colorado Supreme Court opinion addresses two substantially similar ballot initiatives—Proposed Initiative 2025-2026 #240 (“Initiative #240”) and Proposed Initiative 2025-2026 #327 (“Initiative #327”)—both aimed at changing Colorado’s congressional redistricting landscape before the next decennial cycle.

Parties. Wayne Williams (pro se) petitioned against Initiative #240; Curtis Hubbard petitioned against Initiative #327. Respondents were the initiatives’ designated proponents (Tanya Nathan and Lindsey Rasmussen for #240; John Brackney and Robyn Carnes for #327) and the Ballot Title Setting Board (“Title Board”).

Background framework. In 2018, Colorado voters adopted Amendment Y, codified at article V, sections 44 to 44.6 of the Colorado Constitution, creating an independent congressional redistricting commission (“Commission”) and establishing criteria and procedures for adopting congressional maps. The constitutional scheme limits Commission mapmaking to a “redistricting year” following each federal decennial census and requires adherence to specific criteria (including partisan fairness constraints) and public-process protections.

Key legal issue. Whether each initiative satisfies Colorado’s constitutional and statutory single subject requirement—i.e., whether it contains only one subject “clearly expressed in its title,” as required by Colo. Const. art. V, § 1(5.5) and § 1-40-106.5, C.R.S. (2025).

II. Summary of the Opinion

The Court held that both Initiative #240 and Initiative #327 violate the single subject requirement because each contains at least two distinct subjects:

  1. Changing the redistricting process by temporarily authorizing mid-decade congressional redistricting (and displacing the constitutional, Commission-centered timing/criteria/process safeguards); and
  2. Adopting a specific congressional district map (in statute) to govern the 2028 and 2030 election cycles.

Because these purposes are “distinct and separate” rather than “necessarily and properly connected,” the Court reversed the Title Board’s actions, ordered the titles/ballot titles/submission clauses struck, and directed the initiatives be returned to proponents.

III. Analysis

A. Precedents Cited

1. Deference to the Title Board and the “clear case” standard

  • In re Title, Ballot Title & Submission Clause for 2015-2016 #132, 2016 CO 55, ¶ 10, 374 P.3d 460, 464: The Court reiterated that it applies “all legitimate presumptions” favoring the Title Board’s actions.
  • In re Title, Ballot Title & Submission Clause for 2011-2012 #3, 2012 CO 25, ¶ 6, 274 P.3d 562, 565: Quoted for the presumption of propriety afforded to the Title Board.
  • In re Title, Ballot Title & Submission Clause for Proposed Initiative 2025-2026 #158, 2026 CO 13, ¶ 13, 585 P.3d 232, 236: The Court emphasized it overturns single-subject determinations “[o]nly in a clear case,” while still examining initiative text and title compliance.

How these cases influenced the outcome: The Court framed its review as limited and deferential but concluded this was nonetheless a “clear case” because the initiatives combined a fundamental process change with adoption of a particular map.

2. The purpose of the single subject requirement: anti-logrolling and anti-surprise

  • In re Title, Ballot Title & Submission Clause for 2019-2020 #3, 2019 CO 57, ¶ 14, 442 P.3d 867, 870: Used to explain logrolling concerns—preventing bundling that could induce “yes” votes from different factions that would not support each element separately.
  • In re Title, Ballot Title & Submission Clause for 2015-2016 #132, 2016 CO 55, ¶¶ 13–14, 374 P.3d at 465: Cited for both the anti-logrolling rationale and the “surprise and fraud” concern, including the metaphor of a surreptitious provision “coiled up in the folds” of a complex initiative.
  • In re Title, Ballot Title & Submission Clause for Proposed Initiative 2001-2002 #43, 46 P.3d 438, 442 (Colo. 2002): Quoted in the “coiled up in the folds” discussion; reinforces the voter-protection rationale.

How these cases influenced the outcome: The Court’s reasoning turned heavily on logrolling risk: voters might support mid-decade redistricting authority (or suspension of Commission criteria) without supporting a particular partisan map, or vice versa.

3. What counts as a single subject: “necessarily and properly connected” vs. “distinct and separate”

  • In re Title, Ballot Title & Submission Clause for 2011-2012 #3, 2012 CO 25, ¶ 9, 274 P.3d 562, 565: Provides the “necessarily and properly connected” formulation.
  • In re Title, Ballot Title & Submission Clause for Proposed Initiative 2025-2026 #158, 2026 CO 13, ¶¶ 18–19, 585 P.3d 232, 237: Clarifies that an “overarching theme” is not enough if the measure has at least two distinct purposes or is susceptible to logrolling/misleading voters.
  • In re Title, Ballot Title & Submission Clause for 2013-2014 #90, 2014 CO 63, ¶ 11, 328 P.3d 155, 159: Quoted for the proposition that a multi-subject initiative “relates to more than one subject and has at least two distinct and separate purposes.”
  • In re Title, Ballot Title & Submission Clause for 2015-2016 #73, 2016 CO 24, ¶ 14, 369 P.3d 565, 568: Used to support the “necessarily and properly connected” inquiry in distinguishing connected implementation detail from a separate objective.

How these cases influenced the outcome: The Court treated “mid-decade redistricting authorization” and “adoption of a specific map” as distinct ends, not as implementation details of one end.

4. Implementation details vs. separate subject

  • In re Title, Ballot Title & Submission Clause & Summary for 1997-1998 #74, 962 P.2d 927, 929 (Colo. 1998): The Court relied on this to acknowledge that an initiative may include details necessary to implement a single purpose without creating multiple subjects.
  • In re Title, Ballot Title & Submission Clause for 2019-2020 #315, 2020 CO 61, ¶¶ 1, 20, 500 P.3d 363, 365, 368: Cited as an example where revenue reallocation provisions were “implementing provisions” necessarily related to creating and administering a preschool program.

How these cases influenced the outcome: The Court used these decisions as contrasts: unlike administrative mechanisms or funding provisions, altering the constitutionally enshrined timing/entity/criteria for redistricting was deemed a “seismic shift,” not a mere mechanism to make a particular map effective.

5. Overly broad labels and “single subject by theme” rejected

  • In re Title, Ballot Title & Submission Clause for 2021-2022 #16, 2021 CO 55, ¶ 22, 489 P.3d 1217, 1222: Cited for rejecting vague unifying labels that could permit “incongruous and disconnected provisions.”
  • In re Title, Ballot Title & Submission Clause & Summary for 1997-1998 #64, 960 P.2d 1192, 1200 (Colo. 1998): Quoted within #16 to illustrate why overly broad subject labels undermine the single-subject requirement.

How these cases influenced the outcome: The proponents’ framing—“congressional redistricting”—was deemed too broad, because it could mask bundling and facilitate logrolling.

6. Redistricting baseline and constitutional structure

  • People ex rel. Salazar v. Davidson, 79 P.3d 1221 (Colo. 2003): The Court cited this decision in describing Colorado’s redistricting framework and in characterizing how altering redistricting timing/frequency interacts with long-settled redistricting law and constitutional structure.

7. Related same-day decision

  • In re Title, Ballot Title & Submission Clause for Proposed Initiative 2025-2026 #241, 2026 CO 58: Cited for logrolling concerns in the context of other, similar congressional redistricting initiatives considered in the same election cycle.

B. Legal Reasoning

The Court’s analysis proceeded in three main steps:

1. Identify the initiatives’ operative components

Both initiatives did two big things for the 2028 and 2030 cycles: (a) they amended the Colorado Constitution (art. V, § 44) to add subsection (1.5), temporarily authorizing mid-decade redistricting and instituting a specific judicial-review role for the supreme court; and (b) they enacted a detailed statutory map (§ 2-1-101.7) to replace the existing Commission-drawn map for those cycles.

2. Decide whether “mid-decade authorization” is merely an implementation detail of “adopting a map”

The proponents argued that temporary mid-decade authorization functioned like an “effective date” or necessary mechanism to put the new maps in place before 2031, when the Commission would resume its decennial work.

The Court rejected that characterization. It viewed the mid-decade authorization as a fundamental alteration to the constitutionally entrenched redistricting structure—particularly because it:

  • displaced the Commission’s constitutionally assigned authority during the interim period;
  • sidestepped Amendment Y’s constraints against drawing maps to advance partisan interests (Colo. Const. art. V, § 44.3(4)(a)); and
  • disregarded the Commission’s public hearing/comment procedures (Colo. Const. art. V, § 44.4).

In short, the Court treated “whether Colorado should allow mid-decade redistricting under altered criteria and by a different actor” as a policy question separable from “which specific map should govern 2028/2030.”

3. Apply the anti-logrolling function to the initiatives’ structure

The Court emphasized that bundling these distinct questions invites logrolling. It offered a realistic voter-behavior account:

  • Some voters might like the idea of redrawing districts mid-decade (or temporarily changing criteria or removing the Commission) but oppose the specific map.
  • Others might favor the specific map’s partisan outcomes but oppose destabilizing the once-per-decade redistricting cadence and constitutional process.

Combining both elements in one measure could “secure the enactment” of something that could not pass “upon [its] merits” alone—precisely what § 1-40-106.5(1)(e)(I) and the constitutional single-subject rule are designed to prevent.

Holding distilled: Even if “congressional redistricting” is the broad theme, these initiatives contain two distinct purposes—(1) temporary structural/process change enabling mid-decade redistricting and (2) enactment of a particular interim map—so they fail the single-subject requirement.

C. Impact

1. Practical effect on initiative drafting in redistricting

The decision draws a sharper boundary between (a) a measure that adopts a map and (b) a measure that changes the constitutional redistricting architecture (timing, actor, criteria, process). Drafters seeking to place a new map on the ballot should anticipate that pairing map adoption with a structural mid-decade authorization is vulnerable to single-subject challenge unless the Court would view the structural change as genuinely ancillary and not a separate policy objective.

2. Reinforcement of Amendment Y’s structural protections

While the Court did not adjudicate the merits of the initiatives’ policy goals, its characterization of mid-decade authorization as a “seismic shift” underscores the judiciary’s sensitivity to attempts to circumvent the Commission-based model and its constitutionally mandated criteria and procedures—particularly anti-partisan-gerrymandering and public participation features.

3. Litigation posture and Title Board review

The opinion confirms that even under deferential review, the Court will reverse in a “clear case” when an initiative bundles separable policy choices in a way that implicates logrolling concerns. This is likely to encourage both:

  • more granular segmentation of initiative proposals into discrete measures; and
  • more frequent single-subject challenges where proponents attempt to combine “process” reforms with “substantive outcomes” (like adopting a particular map or policy result).

IV. Complex Concepts Simplified

Single subject requirement
Colorado requires that a ballot initiative contain only one subject. The point is to ensure voters can express a clear preference and to prevent bundling unrelated proposals.
Logrolling
Combining multiple proposals in one measure so that supporters of different parts vote “yes,” even if they would oppose other parts if voted on separately.
“Necessarily and properly connected”
Provisions can be grouped together if they genuinely work toward one objective and are connected in a way that is more than thematic—often as true implementing details rather than independent policy decisions.
Title Board and § 1-40-107(2) review
The Title Board sets an initiative’s title and ballot language. The Colorado Supreme Court can review that action in an original proceeding, but it does not decide whether the initiative is wise or constitutional on the merits—only whether it complies with procedural requirements like single subject and clear title.
Mid-decade redistricting
Redrawing congressional districts outside the ordinary once-per-decade schedule tied to the federal census. Here, that meant redrawing for 2028/2030 rather than waiting for the post-2030-census cycle.
Amendment Y / Independent Commission model
Colorado’s constitution assigns congressional mapmaking to an independent commission and requires specific criteria (including partisan fairness constraints) and public procedures. The initiatives attempted to temporarily bypass parts of that model.

V. Conclusion

2026 CO 57 establishes a clear rule for Colorado’s initiative single-subject doctrine in the redistricting context: an initiative that (1) temporarily alters the constitutional redistricting process to allow mid-decade redistricting and (2) enacts a specific interim congressional map contains multiple subjects, not one.

The Court’s reversal of the Title Board emphasizes that “congressional redistricting” is too broad a label to unify distinct policy choices, particularly when the combination risks logrolling. Going forward, proponents seeking mid-decade redistricting changes or interim maps should expect to present those objectives separately—or draft with heightened attention to whether structural reforms can be defended as true implementation rather than a second, independent purpose.
