Colorado Supreme Court blocks congressional-redistricting measures from November ballot
The Colorado Supreme Court has rejected ballot measures that sought to replace the state’s congressional districts, keeping the proposals off the November 2026 ballot.
In its June 29 ruling, the court found that the measures addressed multiple subjects and therefore violated the Colorado Constitution’s single-subject requirement. The decision concerns the proposed ballot measures, not a new congressional map adopted by the court or the legislature.
The result is that Colorado voters will not be asked in November to approve or reject these particular redistricting proposals. The existing redistricting process remains in place for the 2026 election unless it is changed through a later legal or legislative action.
A ruling on ballot-measure requirements
The case reached the Colorado Supreme Court at the ballot-measure review stage. The court’s decision rejected measures designed to let voters replace Colorado’s congressional districts before the 2026 election.
The court’s stated basis was Colorado’s constitutional single-subject rule. Under the ruling as reported, the measures covered multiple subjects rather than the single subject required for a ballot measure. That constitutional finding prevented the proposals from moving forward to the November ballot.
The ruling does not represent a statewide vote on congressional redistricting. No November vote will occur on these measures because the court rejected them before the election. It also does not establish a replacement set of congressional districts.
What remains in place
Colorado’s current redistricting framework is preserved by the decision reported June 29. That means the proposed ballot route to replacing congressional districts will not be available to voters in the November 2026 election through these measures.
The court’s ruling is limited to the measures before it. It should not be read as a permanent bar on every future effort to change congressional districts or the process used to draw them. The approved reporting states that the existing process remains in effect unless a later legal or legislative action changes it.
That distinction matters because the court ruled on whether these ballot measures met a constitutional requirement, rather than deciding that congressional districts can never be altered. The decision resolves the reported challenge to these proposals and their place on the 2026 ballot.
Who is affected
The immediate effect falls on Colorado voters, who will not see the rejected measures on their November ballots. It also affects the state’s congressional-districting system, because the proposals were intended to replace the districts through a voter-approved change.
The measures were described as Democratic-backed, and Fair Maps Colorado was identified in connection with the effort. The court’s ruling does not establish a partisan motive for the decision; its reported rationale was the single-subject requirement in the state Constitution.
No court docket number or full opinion text was included in the approved source material. The material also did not establish whether proponents planned to seek rehearing or pursue another procedural challenge. What is confirmed is the immediate election consequence: the measures will not appear on the November 2026 ballot.
For the 2026 election, Colorado’s congressional redistricting framework therefore remains the operative one unless and until a subsequent legal or legislative development changes it.
