A woman who says her performance as acting general counsel at Roy F. Weston Inc. was described as “extraordinary” by Weston’s president has sued the company, claiming she was fired for complaining when Weston passed her over and chose a male lawyer from outside the company to fill the spot permanently.

Lee D. Wheeler, of West Chester, alleges in a complaint filed in federal court that during her six-year tenure in the West Chester-based infrastructure-redevelopment company’s legal department, the company paid her less than similarly situated male lawyers.
