The U.S. Attorney’s Office in Boston released the indictment on Thursday, charging Judge Shelley Richmond Joseph with obstruction of justice. Federal prosecutors also secured the indictment of Wesley MacGregor, a court officer, for obstruction and perjury. The charges constitute a remarkable intrusion into the internal affairs of a state judiciary and possible retaliation against Massachusetts’ “sanctuary” policies. Rarely in modern history has the federal government sought to punish a state judge acting in exercise of judicial functions. This prosecution sends a clear threat to state courts around the country that do not want to be commandeered by ICE.
