"Gov. Chris Christie's administration filed an appeal Tuesday over a state Superior Court ruling that it must pay another $1.6 billion in New Jersey's public worker pension fund.... At the same time, Christie's lawyers filed a motion asking the state Supreme Court to take up the case, which would trump the appellate court proceedings.... Attorneys for Christie have argued that contract was invalid from the start and the governor can't be forced to restore the payment. The appeal revives that argument, saying the trial court 'fabricated a constitutional right to pension funding' that crimps powers belonging to the Legislature, governor and residents."
