NEW ORLEANS - A Louisiana federal judge on April 10 denied a marine operations firm's motion to compel London arbitration of a declaratory judgment action filed by various underwriters in relation to coverage for raising a vessel after a deliberate flood, finding that the issues in the arbitration and litigation were not inseparable (Mosaic Underwriting Service Inc., et al. v. Moncla Marine Operations LLC, et al., No. 12-2183, E.D. La.; 2013 U.S. Dist. LEXIS 52293).
