ATLANTA - The 11th Circuit U.S. Court of Appeals on April 10 dismissed an appeal of a ruling that compelled arbitration of a seaman's injury-related claims against a cruise line, finding that he did not previously raise the issue of unconscionability and could not raise it for the first time on appeal (Roy David Castillo Arauz v. Carnival Corp., d.b.a. Carnival Cruise Lines Inc., Futura Cruises Inc., No. 11-13865, 11th Cir.; 2012 U.S. App. LEXIS 7116).
