In a dispute stemming from various reinsurance claims arising from the Claimant’s participation in an excess of loss reinsurance program which protected the Respondent’s casualty book of business, IRA Brasil Resseguros challenged an arbitration panel’s ruling in favor of CX Reinsurance Company before the UK High Court of Justice, Queen’s Bench Division. Mr. Justice Burton granted leave to hear four issues on appeal: (1) the standard of proof required for a reinsured to prove his case under a “double proviso” follows settlements clause; (2) the correct approach to considering the question of proof of loss under such a follow settlements clause; (3) what proof is required in relation to a “losses occurring during” clause; and (4) the test for whether a loss was a loss “arising out of an event.” The court, after considering and applying both UK precedent (for issues 1 and 2) and US case law (for issues 3 and 4) determined that the arbitrators had correctly applied applicable law and dismissed the appeal accordingly.IRB Brasil Resseguros SA v.
