BP says investors’ lawsuits must be filed in U.K.

BP P.L.C. asked a Texas judge to throw out lawsuits by some institutional investors on the grounds that their claims that company mismanagement caused the Gulf of Mexico oil spill should be tried in British courts. Investors sued London-based BP’s board and management last year, alleging they pursued cost-cutting over safety and disregarded “red flags” that could have prevented the explosion of the Deepwater Horizon, which sank while drilling a BP well off the Louisiana coast.
