Burwell](http://www.forbes.com/sites/michaelcannon/2013/12/31/for-reporters-law-professors-citizens-a-reference-guide-to-president-obamas-illegal-obamacare-taxes/#halbig)*, federal courts have ruled that the Internal Revenue Service is misinterpreting the Patient Protection and Affordable Care Act, unlawfully paying billions of dollars to private health insurance companies, and unlawfully subjecting more than [50 million individuals and employers](http://www.forbes.com/sites/michaelcannon/2014/07/21/halbig-v-burwell-would-free-more-than-57-million-americans-from-the-acas-individual-employer-mandates/) to the Act’s individual and employer mandates.

Is the IRS acting within the confines of the law? Is the ACA unworkable as written? Is it inevitable that the Supreme Court will hear one of these cases, or a similar challenge yet to be filed? What is the impact of the IRS’s (mis)interpretation? What impact would a ruling for the plaintiffs have on the health care sector and the ACA?
