A state Superior Court judge has filed a suit accusing Bergen County’s assignment judge of gender discrimination and creating a hostile work environment.

Deborah Gross-Quatrone, who serves in the Civil Division in Essex County but previously was a family judge in Bergen County, filed the suit against Assignment Judge Bonnie Mizdol in federal court on Thursday. The suit follows an Advisory Committee on Professional Conduct complaint issued against Gross-Quatrone in March concerning her actions while working under Mizdol.
