The results of two North Jersey mayoral elections are being challenged in court, even though the certified winners will take office on January 1. In Parsippany, a suit alleging voting irregularities filed by Republican Rosemarie Agostini will be heard in Superior Court on January 4. Agostini, a Councilwoman who has run for Mayor four times, lost to Democrat Michael Luther by 40 votes. The case has attracted two high-profile lawyers: John Carbone will represent Agostini and Angelo Genova is Luther’s attorney. Former Edison Councilman William Stephens, a Democrat who ran for Mayor as an Independent, say his 270 vote loss to Democrat Jun Choi was also a result of irregularities and campaign finance fraud. A Middlesex County Judge has not yet decided whether to hear Stephens’ complaint.
