The Colorado Supreme Court rules against three ballot measures that would have changed how the state handles congressional redistricting before the 2028 elections. Multiple outlets report that the court throws out the proposals, which were supported by Democrats and designed to allow a new congressional map to be put in place in advance of the 2028 vote.

The court’s decision applies Colorado constitutional requirements, with sources describing a violation of the state’s “single subject” rule, which requires ballot initiatives to address only one issue. Outlets also note that the court views the measures as attempting to alter long-settled redistricting law in a way that goes beyond the initiatives’ stated purpose by changing elements such as the timing, frequency, criteria, or the entity responsible for congressional redistricting.

As a result of the ruling, the rejected measures do not move forward to voters, and the proposals’ goal of positioning Democrats to win additional House seats is blocked. The decision also reduces the immediate momentum for similar redistricting ballot efforts in other states ahead of the 2028 election cycle.
