While he was Attorney General, in 2003 the Government of Guam attempted to borrow over $350 million which Moylan considered a violation of the debt limitation provisions of the Guam Organic Act of 1950. The Supreme Court of Guam was asked to decide the issue by Governor Felix Perez Camacho. When the Guam Supreme Court's rejected Moylan's legal position, he appealed their decision to the Ninth Circuit Court of Appeals under the Ninth Circuit's discretionary review authority. The Ninth Circuit granted Moylan's writ of certiorari request. After oral argument, a change in federal law deprived the Ninth Circuit of jurisdiction. Moylan then filed a writ of certiorari in the U.S. Supreme Court, which agreed to hear his appeal in 2006. The U.S. Supreme Court reversed the Supreme Court of Guam and ruled in Moylan's favor in 2007 in "Limtiaco v. Camacho", after his term expired in December 2006.
