In an arbitration procedure, if a party that knows that any provisions of this Act or rules of an arbitration procedure which have been provided by the agreement of the parties (limited to those unrelated to public order) have not been complied with does not state their objection without delay (or if a period within which an objection should be stated is provided for, within the period), the party is deemed to have waived their right to object, unless otherwise agreed between the parties.
仲裁手続においては、当事者は、この法律の規定又は当事者間の合意により定められた仲裁手続の準則(いずれも公の秩序に関しないものに限る。)が遵守されていないことを知りながら、遅滞なく(異議を述べるべき期限についての定めがある場合にあっては、当該期限までに)異議を述べないときは、当事者間に別段の合意がない限り、異議を述べる権利を放棄したものとみなす。
