(CNN) - A day after President Obama signed the health care reform bill, Virginia Gov. Bob McDonnell will put his signature Wednesday on legislation to outlaw the federal government from forcing state residents to purchase health insurance.
The Virginia measure, passed by the state's general assembly last month, directly conflicts with the new federal mandates that all Americans purchase some form of health insurance starting in 2014.
In an effort to sustain the Virginia law, the state's attorney general, Ken Cuccinelli, filed a lawsuit Tuesday in federal district court in Richmond arguing the federal insurance law is an unconstitutional overreach of Congressional power.
While proponents of the measure argue that Congress acted within its authority under the Constitution's Commerce Clause provision, Cuccinelli's complaint says the U.S. Supreme Court has never ruled that the clause allows Congress to require citizens to purchase a good or service like health insurance.
Cuccinelli's complaint also argues that the Virginia law McDonnell is signing Wednesday trumps the federal law because it is a matter assigned to the states under the Constitution's 10th Amendment. That amendment says that all powers not explicitly granted to the federal government remain with the states.
Idaho has enacted a similar law outlawing individual mandates, and more than a dozen other state attorneys general - led by Florida's Bill McCollum - filed a lawsuit Tuesday challenging the constitutionality of the federal health care law.
