Tommy Parker may have been involved in some unsavory activities as an officer in a failed savings and loan institution. A federal agency, the Office of Thrift Supervision (OTS) ordered Tommy not to spend or waste any of his own assets while it was investigating him. Later, Tommy and his wife, Billie, got divorced and divided their property. On February 18, the OTS filed papers in court asking for an order that Billie not spend any of her assets. Billie received a copy of the papers on February 20, and the hearing took place on February 24, without Billie in attendance. The court ordered Billie not to spend any assets except for essential living expenses. Billie appealed, claiming that under court rules she was entitled to five days' notice before the hearing took place and that weekend days are not counted. She had had only two business days' notice. Assume that her counting of the days was correct (which it was). Explain the difference between procedural law and substantive law. Which type of law was Billie relying on? Should her appeal be granted?
