(Corrects unit name to National Public Finance Guarantee Corp)
Aug 9 A unit of insurer MBIA Inc.
challenged Stockton, California's bankruptcy on Wednesday,
saying the case was invalid because the city didn't first
negotiate with its biggest unsecured creditor, the California
Public Employees' Retirement System.
The National Public Finance Guarantee Corp., which insured
nearly $94 million of the city's revenue bonds, said the city
was required to negotiate in good faith with creditors before
filing, according to the objection filed in bankruptcy court.
