The facts
The UK Supreme Court unanimously allowed the insurer’s appeal on 28 October 2026 in The Kingdom of Spain and another v The London Steam-Ship Owners’ Mutual Insurance Association, [2026] UKSC 36. [1][2]
The court held that Spain and France, when enforcing rights derived from the insurance contract, were bound by its London arbitration clause and breached a contractual obligation by litigating instead. [1][2]
The court said monetary relief for that breach was available as common-law damages, not equitable compensation, and that the arbitrators’ monetary awards were justified on that basis. [1][2]
The dispute stems from the Prestige tanker sinking off Spain in 2002 and oil pollution affecting Spanish and French coastlines. [1][2]
The court’s decision does not establish that any awarded amount has been paid. [1]
Still unconfirmed
