This article deals with the concept of “proper notice” of arbitration proceedings within the meaning of the Arbitration Act 1996 s 103(2)(c) and the wider notion of natural justice. There used to be very little English law authority in relation to this concept and the position was unclear. Zavod Ekran v Magneco Metrel has shed light on this point. The court has helped crystallise the definition of “proper notice” and provided useful guidance. In particular, “in the context of international commerce, the fact that notice of an arbitration was received in England in a language other than English should not, in itself, affect the validity of the notice” (but might do in some circumstances).
