Atlanta, GA (CNN) -- It's become known as the signature legislation of President Obama's time in office.
And around 10 o'clock Thursday morning, we'll know if Obamacare has stood up against a constitutional challenge.
President Obama defended the Patient Protection and Affordable Care Act during a campaign stop in Atlanta Tuesday.
He says there's no reason for another health care debate.
"And the American people understand that we're not going to make progress going backwards. We need to go forward. They understand we don't need to re-fight this battle over health care. It's the right thing to do. We've got three-million young who are on their parents' health insurance plans that didn't have it before. It's the right thing to do to give seniors discounts on prescription drugs. It's the right thing to do to give 30-million Americans health insurance that didn't have it before. They want to go forward. They understand it's the right thing to do," says President Barack Obama.
Thursday, the Supreme Court will release its ruling on the constitutionality of the health care reform law.
The Patient Protection and Affordable Care Act established a series of reforms over several years including: Banning insurance companies from denying coverage to people with pre-existing conditions, and forbidding insurers from setting a dollar limit on health coverage payouts.
What the justices decide will have an immediate and long-term impact on all Americans, both in how they get medicine and health care.
