Congress is busily making plans for legislative action should the latest challenge to Obamacare prevail in the Supreme Court.

On Wednesday, the justices will hear arguments in King v. Burwell to decide whether the IRS had the authority to write a rule authorizing subsidies to go to millions of people in the 37 states with federal exchanges.

The plaintiffs say the language of the law is clear: Subsidies are allowed in “an Exchange established by the State under [section] 1311of the Patient Protection and Affordable Care Act.” It doesn’t just say this once, but nine times in various linguistic forms.

That is the point that MIT economist Jonathan Gruber made when he famously said: “If you’re a state, and you don’t set up an exchange, that means your citizens don’t get their tax credits.”

The day of reckoning for President Obama’s lawless rollout of Obamacare finally will arrive this week when the Supreme Court hears oral arguments in King v. Burwell. Americans who are interested in the rule of law should hope that when the SCOTUS hands down its decision–most likely on the very last day of the term this June–it will rule to enforce the law that was actually written, not the law the IRS wishes had been written. But those like me who are interested in good health policy are looking forward to an important side-benefit of such a principled decision. It finally may give us a crude market test for a poorly conceived and badly marketed product that so far has survived only because it has a federally enforced monopoly behind it.

The Obama Administration’s abuse of executive power—dispensing with its duty to faithfully execute statutes to become a law maker unto itself—has become the most consequential dispute across the three branches of government. The Supreme Court rejoins this debate on Wednesday with oral arguments in the challenge to the White House’s illegal Affordable Care Act subsidies.

By our count at the Galen Institute, more than 49 significant changes already have been made to the Patient Protection and Affordable Care Act: at least 30 that President Obama has made unilaterally, 17 that Congress has passed and the president has signed, and 2 by the Supreme Court.

As we approach oral argument this week at the Supreme Court in the King v. Burwell case, critics of the latest legal challenge to an Affordable Care Act provision are predicting a disaster of biblical proportions if the Court overturns an IRS rule and declares as illegal the current insurance subsidies for coverage in health exchanges established by the federal government.

This endless loop of major media reporting seems to be taking its cues from the original Ghostbusters movie script. “Fire and brimstone coming down from the skies! Rivers and seas boiling! Forty years of darkness! The dead rising from the grave! Human sacrifice! Dogs and cats, living together! Mass hysteria!” But only the “mass hysteria” part may be accurate for some of those news and commentary outlets.

Wednesday, the Supreme Court will hear oral arguments about whether the Obama administration used the IRS to deliver health insurance subsidies to Americans in violation of the law. Millions of Americans may lose these subsidies if the court finds that the administration acted illegally. If that occurs, Republicans have a plan to protect Americans harmed by the administration’s actions.

When the court rules in King v. Burwell, we anticipate that it will hold the administration to the laws Congress passed, rather than the laws the administration wishes Congress had passed, and prohibit subsidies in states that opted not to set up their own exchanges, as the language in the law clearly states. Such a ruling could cause 6 million Americans to lose a subsidy they counted on, and for many the resulting insurance premiums would be unaffordable.

Republicans have a plan to create a bridge away from Obamacare.

First and most important: We would provide financial assistance to help Americans keep the coverage they picked for a transitional period. It would be unfair to allow families to lose their coverage, particularly in the middle of the year.

In King v. Burwell, four Virginia residents are a challenging an IRS Obamacare rule in the Supreme Court. While the case involves only a handful of plaintiffs, it is really about the millions of Americans who are victims of Obamacare’s mandates and penalties.

Like the King plaintiffs, millions are harmed by Obamacare’s individual mandate, which forces them to either buy insurance that they don’t want or to pay a tax penalty. But the IRS rule also has devastating consequences for countless other Americans and their families.

OUR VIEW: If Obamacare plaintiffs win, millions lose

On March 4, 2015, the Supreme Court will hear oral arguments in King v. Burwell. The key issue in this case is how the government may provide subsidies to people buying health insurance through government exchanges created by the Affordable Care Act, or ObamaCare. This case could also determine whether millions of Americans are free from the law’s onerous mandates and fines.

There are effectively two categories of exchanges: those “Established by a State” (described in Section 1311 of the law’s text) and the federal exchange (described in Section 1321). The statute authorizes the federal government to provide subsidies to enrollees in the state-established exchanges, but not the federal exchange.

When it became clear that many states — today as many as 37 — would not establish their own exchanges, the IRS issued a rule in 2012 allowing those who purchase insurance through the federal exchange to also receive subsidies. Plaintiffs in King v. Burwell claim the IRS acted illegally and did not have authority to do this.

Ultimately, it is up to the Court to declare that the Administration must uphold the law as written by Congress, not to refashion the law. A ruling in favor of petitioners in King could free millions of people from the law’s most onerous provisions, and could present a great opportunity to move past ObamaCare’s political stalemate and to seek a better path forward for healthcare policy.

As the SCOTUS oral arguments in King v. Burwell draw near, the cacophony from liberal outlets is nearly deafening. The plaintiffs’ position is “absurd ,” they cry. Congress “never contemplated withholding premium subsidies” in noncooperative states. Even the Obama administration argued that “it would have been perverse for Senators concerned about federalism to insist on pressuring States to participate in the implementation of a federal statute.”[1]

Perverse? Jonathan Gruber (whose position on the issue is “complicated”[2]) is equally disdainful, calling the challengers’ stance “nutty,” “stupid,” and a “screwy interpretation” of the law.

Really? Were Obamacare architects incapable of using “sticks” masquerading as “carrots” to coerce states into setting up Exchanges?

The Obamacare window technically just closed this weekend, but a new round of political headaches could just be beginning for the administration.

That’s because it’s tax season, and many Americans could soon be getting an unwelcome surprise that they owe the government a penalty for skipping health insurance coverage.

Up to 6 million Americans are expected to pay a penalty for not having coverage in 2014, according to recent Obama administration projections. The 2014 penalty for this tax season is $95, or 1 percent of family income — purposefully on the weaker side to let people adjust to this new coverage scheme. Most of the uninsured won’t actually face the penalty because they’ll qualify for an exemption, either related to their inability to afford coverage or some other hardship.
