Trouble on the Horizon?

Yet another provision of the ACA, this one concerning ACA subsidies, is under scrutiny, this one could change health insurance as we know it. A case which has become the topic of discussion as of late is Halbig v. Burwell. This is one of four currently flowing through the appeals process, with similar emphasis and focus.
The Issue

According to the wording in the Affordable Care Act Section 1311, ACA  subsidies should be issued to plans purchased “through and Exchange established by the State under Section 1311”.

History

Johnathan Adler, a law professor at Case Western Reserve University in Ohio wrote a research paper. In performing his countless hours of research, he came across language in the ACA that caused him to question the validity of a particular provision in the ACA which clearly states that tax credits/subsidies can only be issued through state exchanges and doesn’t apply to federal exchanges.  Johnathan Adler contacted Michael Cannon, the libertarion Cato Institute’s director of health policy studies, in which he voiced this particular language could present serious potential implications for the law, therefore the law should be challenged.  The court case was heard in January 2014 and was decided that that wording of the ACA should stand as is. The ruling stated that it was the intent of this provision to provide tax credits to all Americans who participated in the exchanges, and not just those who participated in the state-run exchanges.

The decision was appealed.

In March 2014, oral arguments were heard by several judges.

July 2014, a decision is to be made as to whether the appeal is upheld or denied.

Opponents

The opponents to the court case state that the law clearly only provides subsidies/credits to those who are part of state-run exchanges. The particular wording is mentioned in the ACA at least 7 times.

Proponents

The proponents state that the intent was to have the subsidies apply to all those on the exchanges who meet the qualifications, regardless whether federally or state-run. The intent was originally to have all states setup their own exchanges. However, this was far from the result. Only about 16 states setup their own exchanges with the rest defaulting to federally run exchanges. The wording, however, was never changed.
Potential implications if the appeal stands
