A federal judge in San Francisco has found that a former nonequity shareholder of national labor and employment firm Ogletree, Deakins, Nash, Smoak & Stewart is bound by the firm’s arbitration agreement after she failed to opt out of it.

U.S. District Judge William Orrick III of the Northern District of California on Wednesday found that Dawn Knepper, who filed a proposed $300 million gender discrimination class action against the firm almost a year ago, was subject to the firm’s arbitration agreement after she continued to work at Ogletree past the deadline to sign and return a form opting out of it.
