The Working Group was generally of the opinion that, should not all copies of the bill of lading be produced by the controlling party, the right of control could not be exercised, and that an exception should be made to the rule under which the controlling party should produce all the copies of the bill of lading to address the situation where one copy of the bill of lading was already in the hands of the carrier. In order to meet these concerns, it is suggested that the phrases noted should be added para. 2(c).
