Directed Verdict Obtained in a New Jersey Law Against Discrimination Case
Public Entity & Civil Rights Litigation
Trucking & Transportation Liability
September 18, 2025
We obtained a directed verdict in a New Jersey Law Against Discrimination case filed against a national trucking company after two days of trial. The plaintiff was a laborer who assisted a truck driver making deliveries to a retail store. The driver admitted to making sexually explicit comments to the plaintiff. The plaintiff argued the comments were made due to his race (African American) and were protected under the LAD. Jillian and Len argued that the comments were offensive to anyone who heard them and had nothing to do with the plaintiff’s race.
