Amy Stephens, a Republican from Monument, has signed on as sponsor of a bill that would allow Colorado to opt out of the federal health care overhaul, if other states do the same.
The Healthcare Opportunity and Patient Empowerment Act allows Colorado to join an interstate compact, that if approved by the U.S. Congress, would supersede federal law and give authority to the states.
The Supreme Court has affirmed that such compacts are legal.
The effort comes after voters rejected a constitutional amendment that would ban the state from requiring people to buy health insurance.
However, the new measure can take effect even if the Supreme Court upholds the Affordable Care Act. Five other states have introduced similar compact legislation.
Littleton Republican Mike Kopp is the other sponsor of the bill.
