– The Supreme Court has rejected another challenge to President Obama's health care overhaul.

The justices on Tuesday left in place lower court rulings dismissing a lawsuit against the Affordable Care Act.

The suit argues that the law violates the provision of the Constitution that requires tax-raising bills to originate in the House of Representatives.

In declining to hear that contention, the high court all but ensured that the Affordable Care Act will remain intact through the November election. The rebuff leaves health care as one of the core issues in the presidential and congressional campaigns.

The suit had gained little traction in the lower courts, even as it provoked a party-line divide on the legal reasoning. A federal trial judge in Washington upheld the law, as did a unanimous panel of three Democratic-appointed judges.

A larger panel of judges then voted not to reconsider the case. Although the four Republican appointees on the 11-member Washington appeals court would have heard arguments, they also said they would have upheld the law for different reasons.

The court has twice turned back major challenges to the law, in opinions written by Chief Justice John Roberts in 2012 and in June.

The court also has allowed family-owned businesses with religious objections to opt out of paying for contraceptives for women covered under their health plans.

The Pacific Legal Foundation backed the latest lawsuit, which was filed on behalf of Matt Sissel, an artist in Oregon.
