HOUSTON - A federal judge in Texas on Feb. 6 granted in part and denied in part a motion to dismiss filed by BP PLC and certain of its subsidiaries and former executive officers, ruling that although shareholders have failed to plead scienter against one of the defendants, they have properly pleaded a majority of their claims with regard to the rest of the defendants (In re BP p.l.c. Securities Litigation, No. 10-md-2185, S.D. Texas; 2013 U.S. Dist. LEXIS 15922).
