Colorado Supreme Court blocks ballot initiatives to redraw congressional districts

On June 29, 2026, the Colorado Supreme Court reversed the Title Board’s actions on proposed initiatives #240 and #327, finding that both measures violated Colorado’s multiple-subject rule and related election-law limits.

The practical effect is that Colorado voters will not see these proposals on the ballot through this route. The court said the measures would have opened the door to mid-decade congressional redistricting and new U.S. House districts for the 2028 and 2030 election cycles.

For Colorado, that keeps the 2021 congressional map in place for now. For the broader country, AP reported the ruling is another setback in the national redistricting fight over House control.

The Colorado Judicial Branch says Title Board decisions can be appealed to the state Supreme Court, which may affirm or reverse them on an expedited schedule.
