In the majority opinion of King v. Burwell, Chief Justice Roberts had some harsh words for the "inartful drafting" of the Affordable Care Act, which led to the difficulty in interpreting the phrase "an Exchange established by the State." Roberts wrote:
The Affordable Care Act contains more than a few examples of inartful drafting. (To cite just one, the Act creates three separate Section 1563s. See 124 Stat. 270, 911, 912.) Several features of the Act's passage contributed to that unfortunate reality. Congress wrote key parts of the Act behind closed doors, rather than through "the traditional legislative process." Cannan, A Legislative History of the Affordable Care Act: How Legislative Procedure Shapes Legislative History, 105 L. Lib. J. 131, 163 (2013). And Congress passed much of the Act using a complicated budgetary procedure known as "reconciliation," which limited opportunities for debate and amendment, and bypassed the Senate's normal 60-vote filibuster requirement. Id., at 159–167. As a result, the Act does not reflect the type of care and deliberation that one might expect of such significant legislation. Cf. Frankfurter, Some Reflections on the Reading of Statutes, 47 Colum. L. Rev. 527, 545 (1947) (describing a cartoon "in which a senator tells his colleagues 'I admit this new bill is too complicated to understand. We'll just have to pass it to find out what it means.'").
