Justice Scalia, joined by Justices Thomas and Alito, maintained that the statutory text was unambiguous: an “Exchange established by the State” means an Exchange established by one of the fifty States or the District of Columbia, not one established by the Federal Government. Because the ACA expressly defines “State” without including the Federal Government, the dissent regarded the majority’s reading as contrary to the words Congress enacted.
In the dissent’s view, context confirmed rather than undermined the ordinary meaning. The ACA repeatedly distinguishes Exchanges created by States under § 18031 from those created by the Secretary under § 18041, assigns them different sources of authority and funding, and makes the federal Exchange a fallback after a State’s failure to establish one. The phrase “such Exchange” means that the federal Exchange has similar functions, not that it was established by the State.
The dissent argued that the majority improperly made the words “by the State” inoperative. Congress used both broader references to an “Exchange” and narrower references to an “Exchange established by the State,” so the difference should be given effect. Other provisions referring to State-established Exchanges, Justice Scalia argued, likewise showed that federal and State Exchanges could not simply be treated as identical.
The provisions cited by the majority did not, in the dissent’s view, require credits on federal Exchanges. A federal Exchange could provide information about the availability of credits, operate a calculator that showed a zero credit, and report that no advance credits were paid. At most, those provisions created imperfections in a large statute; they did not create ambiguity in § 36B’s direct limitation.
Justice Scalia also rejected the majority’s reliance on the ACA’s broader purposes. Even if denying credits on federal Exchanges would destabilize insurance markets, courts may not override clear statutory text to improve a legislative design. Congress could plausibly have restricted subsidies to State Exchanges to encourage States to bear the responsibility of creating them, while using the federal fallback for States that declined.
Finally, the dissent warned that the Court had effectively rewritten the law to preserve the ACA. Whether the statutory design was flawed, poorly drafted, or politically unwise was for Congress to address through amendment. The judiciary’s role, Justice Scalia concluded, was to apply the enacted text rather than revise it to achieve what the Court believed Congress must have intended.
