The F/V Cape Cod, a commercial fishing vessel and the only asset of R&M, sank in 1994; during the accident, DiMercurio, a fisherman, was injured. He sued the company for his injuries and was awarded $350,000. R&M, having no assets, assigned DiMercurio all rights it had against Sphere Drake, the London-based insurer of the boat. DiMercurio took his claim to Sphere Drake, but it denied the demand and invoked the arbitration process specified in the policy, which called for arbitration of all coverage disputes in London. DeMercurio then sued, contesting the validity of the arbitration provision. The district court held for Sphere Drake. DiMercurio appealed. Does he have a valid claim? [DiMercurio v. Sphere Drake Insurance PLC, 202 F.3d 71, 1st Cir. (2000)]
