This case involved a dispute between Entores Ltd and Miles Far East Corporation over a contract for the purchase of copper cathodes. Entores attempted to sue Miles Far East in English courts, but could only do so if the contract was formed within England. The court had to determine whether the contract was formed when Miles Far East sent an acceptance from Amsterdam or when Entores received it in London. The judge ruled that for instantaneous communications like telex, the contract was formed upon receipt of the acceptance, so the contract was formed in London. Therefore, Entores was able to sue in English courts.
