"As the Chief Justice had observed at the oral argument, had the Court simply deferred to the agency, a future administration could have changed the rule. The Court's decision means that if Congress wants to limit tax credits to state-operated exchanges, Congress itself will have to amend the law. The Court proceeded to determine itself what the statute meant. In doing so, the Chief Justice relied throughout on the text, context, and purpose of the ACA, not on legislative history or some abstract notion of congressional intent." [King v. Burwell, No. 14-114 (U.S. June 25, 2015)]
