What it's about

The Supreme Court overturned that ruling, deciding that the Administrative Procedure Act does not impose that extra requirement on agencies.

The D.C. Circuit had required the Labor Department to use public notice-and-comment procedures when significantly changing its interpretation of a regulation.

Question presented

Must a federal agency engage in a notice-and-comment procedure before it can significantly alter an interpretation of a rule of agency regulation?

What the Court decided

Holding

The Paralyzed Veterans doctrine is contrary to the clear text of the APA’s rulemaking provisions and improperly imposes on agencies an obligation beyond the APA’s maximum procedural requirements. 720 F. 3d 966, reversed.

Result
Reversed

The Court's reasoning

The Court said the D.C. Circuit’s rule conflicted with the Administrative Procedure Act’s clear text and required agencies to follow procedures beyond what the law requires.
