Last week, on remand the district court granted Corner Post’s summary judgment motion, applying Loper Bright and concluding that Regulation II was beyond the agency’s power and thus unlawful. The result may have been different under Chevron. As the district court put it, “[w]hen this litigation began roughly fourteen years ago, the Parties were subject to the mire of Chevron deference.” Indeed, as the district court observed, the D.C. Circuit found in related litigation that the Fed’s debit-fee regulation rested on a “reasonable” interpretation of the statute that passed muster under Chevron.
