In a decision with national implications, the Colorado Supreme Court threw out the state's new congressional districts today, saying the GOP-led Legislature redrew the map in violation of the state constitution.
Lawmakers can redraw congressional districts only after each census and before the ensuing general election, the court said in a closely watched 5-2 decision that followed party lines.
"Because the General Assembly failed to redistrict during this constitutional window, it relinquished its authority to redistrict until after the 2010 census," the court said. "There is no language empowering the General Assembly to redistrict more frequently or at any other time."
The justices chastised the lawmakers for claiming they should be able to redraw the maps "two, or even 10 times in a single decade.
"If the districts were to change at the whim of the state Legislature, members of Congress could frequently find their current constituents voting in a different district in subsequent elections," the ruling said.
"We conclude that the General Assembly does not have the unprecedented power it claims," the ruling said. "Federal law grants the states the authority to redistrict, and federal law defines and limits this power. Our state constitution cannot change these federal requirements."
