The Supreme Court has upheld Obamacare subsidies.
From Chief Justice Roberts's majority opinion:
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.’”).
Anyway, we “must do our best, bearing in mind the fundamental canon of statutory construction that the words of a statute must be read in their context and with a view to their place in the overall statutory scheme.” Utility Air Regulatory Group, 573 U. S., at ___ (slip op., at 15) (internal quotation marks omitted). After reading Section 36B along with other related provisions in the Act, we cannot conclude that the phrase “an Exchange established by the State under [Section 18031]” is unambiguous.
Justice Scalia dissented:
The Court holds that when the Patient Protection and Affordable Care Act says “Exchange established by the State” it means “Exchange established by the State or the Federal Government.” That is of course quite absurd, and the Court’s 21 pages of explanation make it no less so.
...
Words no longer have meaning if an Exchange that is not established by a State is “established by the State.” It is hard to come up with a clearer way to limit tax credits
to state Exchanges than to use the words “established by the State.” And it is hard to come up with a reason to include the words “by the State” other than the purpose of
limiting credits to state Exchanges. “[T]he plain, obvious, and rational meaning of a statute is always to be preferred to any curious, narrow, hidden sense that nothing but the
exigency of a hard case and the ingenuity and study of an acute and powerful intellect would discover.” Lynch v. Alworth-Stephens Co., 267 U. S. 364, 370 (1925) (internal
quotation marks omitted). Under all the usual rules of interpretation, in short, the Government should lose this case. But normal rules of interpretation seem always to yield to the overriding principle of the present Court: The Affordable Care Act must be saved.
