A Dewey spokesman confirmed Ms. Danilunas also had withdrawn her U.K. complaint but declined further comment. Ms. Danilunas’ lawyer in New York, Ralph M. Stone at Shalov Stone Bonner & Rocco, referred a request for comment to her London lawyer, David Greene at Edwin Coe, who did not respond to requests for comment.

A trial in Ms. Danilunas’ London case had been set for next month and a case management hearing where an order was expected to be issued had been scheduled for Thursday, according to an order last month by Southern District Judge P. Kevin Castel. Ms. Danilunas claimed her compensation from 2005 to 2008 was lower than it should have been and that Dewey’s compensation system disadvantaged female partners. Dewey in papers filed in London denied any bias in its system.
