A business owner who claims a customer stopped buying from her after she refused to have sex with him can sue his company for sexual harassment under the Law Against Discrimination, an appeals court held Wednesday.

The decision, in J.T.’s Tire Service v. United Rentals North America, Inc., A-2989, may be the first published opinion to address whether a sexual harassment claim can be brought under a section of the LAD that prohibits discriminatory refusal to do business.
