Today, in Arlington v. FCC, the Supreme Court held 6-3 that courts should confer Chevron deference to agency interpretations of ambiguous statutory provisions concerning the scope of agency jurisdiction. Justice Scalia wrote for the majority. Justice Breyer filed an opinion concurring in part and concurring in the judgment. The Chief Justice dissented, joined by Justices Kennedy and Alito.
I participated in an amicus brief in this case, largely based on an article I co-authored with Nathan Sales. Alas, we were on the losing side. My prior posts on this case are here and here, and earlier posts on the issue are here and here.
I hope to have more to say about the decision later today.
