A U.S. labor judge warned lawyers in a federal discrimination case against Oracle America Inc. to watch their “tone and manner,” while permitting the government to bring new and expanded claims alleging widespread bias against women and minorities.

Richard Clark, an administrative law judge, granted the U.S. Labor Department’s request to file an amended complaint against Oracle that would include claims the company’s discriminatory practices have cost women and minority workers more than $400 million in wages. Clark said the Labor Department’s Office of Federal Contract Compliance Programs must still provide more details supporting the allegations.
