A federal judge has denied a regional chamber of commerce's request to block a Philadelphia city ordinance banning employers from asking job applicants about their wage history.

U.S. District Judge Mitchell S. Goldberg of the Eastern District of Pennsylvania denied a preliminary injunction request from the Chamber of Commerce for Greater Philadelphia, which claimed the ordinance is bad for businesses.

The chamber filed its lawsuit claiming the ordinance, enacted to promote wage equity, violates companies' First Amendment rights.
