WASHINGTON (CBSDC/AP) — The Supreme Court on Thursday upheld the nationwide tax subsidies under President Barack Obama’s health care overhaul, in a ruling that preserves health insurance for millions of Americans.

The justices said in a 6-3 ruling that the subsidies that 8.7 million people currently receive to make insurance affordable do not depend on where they live, under the 2010 health care law.

The outcome is the second major victory for Obama in politically charged Supreme Court tests of his most significant domestic achievement. It came the same day the court gave the administration an unexpected victory by preserving a key tool the administration uses to fight housing bias.

Chief Justice John Roberts again voted with his liberal colleagues in support of the law. Roberts also was the key vote to uphold the law in 2012. Justice Anthony Kennedy, a dissenter in 2012, was part of the majority on Thursday.

“Congress passed the Affordable Care Act to improve health insurance markets, not to destroy them,” Roberts wrote in the majority opinion. “If at all possible, we must interpret the Act in a way that is consistent with the former, and avoids the latter.”

Roberts continued, “In this instance, the context and structure of the Act compel us to depart from what would otherwise be the most natural reading of the pertinent statutory phrase.”

In a dissent he summarized from the bench, Justice Antonin Scalia said, “We should start calling this law SCOTUScare.” Using the acronym for the Supreme Court, Scalia said his colleagues have twice stepped in to save the law from what Scalia considered worthy challenges.

“The Court holds that when the Patient Protection and Affordable Care Act says ‘Exchange established by the State’ it means ‘Exchange established by the State or the Federal Government.’ That is of course quite absurd, and the Court’s 21 pages of explanation make it no less so,” Scalia wrote.

Scalia added, “Words no longer have meaning if an Exchange that is not established by a State is ‘established by the State.’ It is hard to come up with a clearer way to limit tax credits to state Exchanges than to use the words ‘established by the State.’ And it is hard to come up with a reason to include the words ‘by the State’ other than the purpose of limiting credits to state Exchanges.”

Justices Samuel Alito and Clarence Thomas joined the dissent, as they did in 2012.

Democratic presidential candidate Hillary Clinton commented on Twitter following the ruling.

“Yes! SCOTUS affirms what we know is true in our hearts & under the law: Health insurance should be affordable & available to all,” she tweeted.

Nationally, 10.2 million people have signed up for health insurance under the Obama health overhaul. That includes the 8.7 million people who are receiving an average subsidy of $272 a month to help pay their insurance premiums.

Of those receiving subsidies, 6.4 million were at risk of losing that aid because they live in states that did not set up their own health insurance exchanges.

The health insurance industry breathed a big sigh of relief, and a national organization representing state regulators from both political parties said the court’s decision will mean stable markets for consumers.

“This decision allows (state officials) to move forward with a level of confidence that their markets will not see significant disruption due to a paradigm shift,” said Ben Nelson, CEO of the National Association of Insurance Commissioners and a former Democratic senator from Nebraska.

Shares of publicly traded hospital operators including HCA Holdings Inc. and Tenet Healthcare Corp. soared after the ruling relieved those companies of the prospect of having to deal with an influx of uninsured people. Investors had worried that many patients would drop their coverage if they no longer had tax credits to help pay.

Republicans said the ruling would not mean the end of the political fight over the law, widely dubbed “Obamacare.”

Sen. Lindsey Graham of South Carolina, a Republican presidential contender, said that for 2016 candidates for Congress or the White House health care will be the “most dominant issue in the country.”

And Senate Majority Leader Mitch McConnell said Democrats who support the law “now have a choice: crow about Obamacare’s latest wobble toward the edge, or work with us to address the ongoing negative impact of a 2,000-page law that continues to make life miserable for too many of the same people it purported to help.”

The challenge devised by die-hard opponents of the law relied on four words – “established by the state” – in the more than 900-page law.

The law’s opponents argued that the vast majority of people who now get help paying for their insurance premiums are ineligible for their federal tax credits. That is because roughly three dozen states opted against creating their own health insurance marketplaces, or exchanges, and instead rely on the federal healthcare.gov to help people find coverage if they don’t get insurance through their jobs or the government.

In the challengers’ view, the phrase “established by the state” demonstrated that subsidies were to be available only to people in states that set up their own exchanges.

The administration, congressional Democrats and 22 states responded that it would make no sense to construct the law the way its opponents suggested. The idea behind the law’s structure was to decrease the number of uninsured. The law prevents insurers from denying coverage because of “pre-existing” health conditions. It requires almost everyone to be insured and provides financial help to consumers who otherwise would spend too much of their paycheck on their premiums.

The point of the last piece, the subsidies, is to keep enough people in the pool of insured to avoid triggering a disastrous decline in enrollment, a growing proportion of less healthy people and premium increases by insurers.

Several portions of the law indicate that consumers can claim tax credits no matter where they live. No member of Congress said that subsidies would be limited, and several states said in a separate brief to the court that they had no inkling they had to set up their own exchange for their residents to get tax credits.

The 2012 case took place in the midst of Obama’s re-election campaign, when Obama touted the largest expansion of the social safety net since the advent of Medicare nearly a half-century earlier. But at the time, the benefits of the Affordable Care Act were mostly in the future. Many of its provisions had yet to take effect.

In 2015, the landscape has changed, although the partisan and ideological divisions remain for a law that passed Congress in 2010 with no Republican votes.

The case is King v. Burwell, 14-114.
