HACKENSACK - Hackensack?s former police chief is arguing his union should foot the bill for legal expenses while he's fighting criminal charges.

Former Police Chief Ken Zisa says he's entitled to legal defense coverage because he's a member of Policemen's Benevolent Association Local 9.

The union, however, argues Zisa hasn't paid his dues since he was made chief in 1995.

Zisa has been charged with insurance fraud and official misconduct. Prosecutors say he intervened in a 2004 assault case and a 2008 car accident. He was relieved of duty in April due to the charges.
