A lawyer acting on behalf of Samsung has defended the company's decision to seed evidence banned in court to the media. John Quinn, a managing partner of the lawfirm Quinn Emanuel Urquhart & Sullivan, insists that the move was "lawful" and "ethical" in a new filing, submitted in response to federal Judge Lucy KohÃs request for an explanation, which was in turn prompted by a complaint from an Apple lawyer. The evidence was emailed to meet requests from the media, according to Quinn.
