Implementing a policy to prevent sexual harassment isn't an effective defense to hostile work environment claims against an employer if the victim isn't aware of the complaint mechanism, the Appellate Division has ruled.

The court on Aug. 3 reversed a summary judgment order granted to Mott's LLP in a suit by a factory worker who claimed she was the target of harassment and inappropriate touching by four male co-workers.

The case is believed to be the first to apply Aguas v. State of New Jersey, a February decision in which the state Supreme Court recognized the affirmative defense for employers that take reasonable steps to prevent sexual harassment.
