AIPLA, in an April 16, 2012 amicus brief filed jointly with other bar associations, argued in support of the petition for rehearing en banc in a suit over the constitutionality of abrogating cost-of-living salary increases for federal judges. The brief argues that the Ethics Reform Act of 1989 provides federal judges with a vested right to future pay that may not be reduced without violating the "Compensation Clause" of the Constitution (Article III, Section 1).
