The US Supreme Court ruled Monday that the New York convention does not conflict with state law doctrines of equitable estoppel which allow non-signatories to an arbitration agreement to compel arbitration.
The case involves an American company (ThyssenKrupp Stainless USA) and a French company (F.L. Industries Inc.), which entered into three contacts, all of which imposed arbitration as the mechanism for dispute resolution between the parties. Per these contracts, F.L. had to build cold rolling mills for ThyssenKrupp’s steel manufacturing plant.
