D.C. Superior Court Judge Judith Retchin on Tuesday threw out the $30 million legal malpractice suit brought by Blackwater Security Consulting against Wiley Rein and the firm’s former partner, Margaret Ryan.

Blackwater sued the Washington law firm in January, alleging that Wiley lawyers neglected critical case law and statutes while defending it in a 2005 wrongful death case brought on behalf of four Blackwater guards brutally killed in Fallujah, Iraq, in 2004.
