In an extremely rare move, the Supreme Court has postponed the first oral argument scheduled for its new term today, South Carolina v. North Carolina. An announcement from the Court came Sunday night. The official reason given was that “family illness” has left Eric Miller, assistant to the U.S. Solicitor General, unable to argue in the case.

Miller’s father is seriously ill, according to a source familiar with the situation. In making the decision, the Court was also said to be aware that the mother of another lawyer arguing in the case died late last week. Karen Bartolomucci, the mother of H. Christopher Bartolomucci of Hogan & Hartson, died last Thursday in Leesburg, Va.
