insist that an agency “examine the relevant data and articulate a satisfactory explanation
for its action.” Motor Vehicle Mfrs. Assn. of United States, Inc. v. State Farm Mut.

In overturning the Commission’s judgment, the Court of Appeals here relied in part on
Circuit precedent requiring a more substantial explanation for agency action that changes
prior policy. * * *
We find no basis in the Administrative Procedure Act or in our opinions for a
