Justice Antonin Scalia added a stellar new entry to the annals of wickedly entertaining U.S. Supreme Court dissents on Thursday.

You didn’t have to read between the lines. You didn’t need to know the subtleties of the government’s defense of a legal challenge to Obamacare: That Congress had flubbed in drafting the law but everyone knew what Congress meant.

“Words no longer have meaning if an exchange that is not established by a state is ‘established by the state’,” Scalia wrote in his icy dissent. “Under all the usual rules of interpretation, in short, the government should lose this case. But normal rules of interpretation seem always to yield to the overriding principle of the present court: The Affordable Care Act must be saved.”

Obamacare? “We should start calling this law SCOTUScare,” Scalia wrote.

Zing.

Chief Justice John Roberts has now twice rescued the Affordable Care Act from legal challenges that would have crippled it. In 2012, Roberts wrote for a 5-4 majority that upheld the law’s individual insurance coverage mandate.

And the conservative chief justice — yes, he still tends to be a conservative — wrote the majority opinion in the 6-3 ruling issued Thursday.

It does remind us of the long-ago comment from Chicago Mayor Richard J. Daley’s press secretary, Earl Bush: “Don’t print what he said. Print what he meant.”

At any rate, the majority accepted the argument that, despite what the law’s language said, Congress did not intend to restrict Obamacare subsidies only to people who got insurance through state-run exchanges.

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

Millions of people whose coverage was at risk, no doubt sighed with relief.

While the legal challenges to Obamacare are winding down, big financial and structural challenges remain.

Many insurers are seeking big premium increases for the next year. Many Americans who signed up for health coverage earlier this year have fallen off the rolls because they didn’t pay their premiums.

President Barack Obama took a victory lap on Thursday, while some GOP presidential candidates and congressional leaders vowed to repeal the law.

It’s time, though, to move on some changes that would preserve the best-liked elements of Obamacare while easing some of the financial pressures, and reverse incentives it has created.

Among them:

Ease the mandate that forces employers to cover employees who work 30 hours a week or more as full-timers. Setting that standard at 40 hours would encourage employers not to greatly curb workers’ hours or cut full-time jobs.

Exempt businesses that have fewer than 100 employees from the mandate to provide coverage that kicks in next year. Many small businesses can’t afford it.

Offer Americans more choices for coverage. A proposed “copper” option, for instance, would appeal to people who want low premiums and protection from the cost of treating a catastrophic illness or injury.

Call it Obamacare or SCOTUScare, it’s the law of the land. It can be vastly improved. It should be.
