As we previously discussed, the issue of deference is a hot topic in the tax arena.  Unfortunately, the Supreme Court of the United States recently passed on the opportunity to address the continuing validity of what is commonly known as Auer deference.  This level of deference sometimes applies when an agency interprets its own regulations.

In United Student Aid Funds, Inc. v. Bryana Bible, S.Ct. No. 15-861, the Supreme Court denied a petition for writ of certiorari, leaving in place an opinion by the Court of Appeals for the Seventh Circuit that deferred to the Department of Education’s interpretation in an amicus brief of the regulatory scheme that it enforces.  In a scathing dissent from the denial of certiorari, Justice Thomas stated that the Auer doctrine “is on its last gasp” and that the Court should have taken the opportunity to reconsider and re-evaluate the doctrine.  The Supreme Court’s rules require that at least four Justice must vote to accept a case.  Although Chief Justice Roberts and Justice Alito have recently acknowledged that the doctrine should be reconsidered, the other vocal member in favor or reconsideration was the recently deceased Justice Scalia.  It remains to be seen whether another current Justice will join these three Justices in the future to vote to revisit the issue.
