Police say the case now returns to Clark County District Court, where a judge last June ruled that Newton owed his former pilot more than $400,000 in back pay.
A lawyer for pilot Monty Ward told the Las Vegas Sun the amount due topped $501,388 last month and is growing at more than $125 per day.
Ward's lawyer, John Muije (MEW'-jee) and Newton representatives did not immediately respond to messages from The Associated Press.
