.. One of Justice Gorsuch’s most controversial opinions also stems from a case that involved the EPA under Ms. Burford’s leadership, Mr. Somin noted. The legal theory of “Chevron deference” says that courts should defer to administrative agencies. It stemmed from a 1984 Supreme Court case involving the EPA’s attempts to regulate air pollution.
Though the Supreme Court upheld deference to the EPA which was led by his mother when the case was first brought, Justice Gorsuch has called the decision an “abdication of the judicial duty” and suggested he would vote to overturn the precedent if a similar case came before the Supreme Court.
