PHILADELPHIA AP – Justice Department efforts to pursue a second fraud trial for an imprisoned cable television mogul and his son amount to constitutionally prohibited double jeopardy, a defense lawyer argued Wednesday before an 11-judge U.S. appeals panel.

Adelphia Communications Corp. founder John Rigas, 85, is already serving a 12-year prison term, while his 53-year-old son, Timothy, is serving a 17-year sentence after federal convictions in New York for fraud and conspiracy.
