NYU law professor Samuel Estreicher comments on Kisor v. Wilkie, a case currently before the US Supreme Court that raises the narrow question whether a court should accept an interpretation by the Department of Veterans Affairs of its own technical regulation but also gets at a broader question of judicial deference more generally. Estreicher argues that when agencies interpret their own regulations, courts should afford those interpretations only Skidmore respect, not the higher Chevron-style deference that has come to be commonplace.
