Great Lakes Reinsurance (UK) PLC v. Sunset Harbour Marina, Inc., et al., Case No. 1:10-cv-24469-KAM

Associate Counsel in Federal Maritime action brought by Plaintiff Subrogee alleging several causes of action against a yacht club and its marina (co-defendants) for the loss of a vessel owned by the Subrogor, which was docked at the marina.  After having obtained Plaintiff’s agreement to withdraw its breach of contract claim against the marina, the Court also granted client’s Motion for Summary Judgment or, Alternatively, Motion to Compel Arbitration, staying the action and compelling arbitration. Thereafter, a Verified Motion for Attorney’s Fees was filed against Plaintiff for having pursued its civil suit, in violation of the agreement to arbitrate, after which a favorable settlement was reached under which its attorneys’ fees and costs for defense of the matter were recuperated and the Plaintiff Subrogee waived any claims it could pursue in arbitration.


Estate of Virginia Murray v. City of Lake Worth and Palm Beach County, Case No. 502011CA005409XXXXMB, and appeal to the Fourth District Court of Appeal, Case No. 13-3958:

Summary Judgment was obtained in favor of the City of Lake Worth in a claim for wrongful death brought by the son and personal representative of a deceased automobile passenger.  After several amendments to the claim brought against the City, Plaintiff ultimately alleged that the City of Lake Worth created a dangerous condition of which it was aware by controlling, operating, and maintaining its electrical power grid in a negligent manner.  After summary judgment was entered in favor of the City, Plaintiff appealed to the Fourth District Court of Appeal, claiming not only that the trial court’s ruling was incorrect but also claiming that the trial court abused its discretion in granting summary judgment given that discovery was alleged to have been in its early stages.  After reviewing the briefs on the matter, the Fourth DCA affirmed per curiam.
