I agree with the explanation of the Parliamentary Secretary as to the purpose of this Amendment. I understand the purpose to be merely to make the method of proof easier and more convenient than it would otherwise be. However, I am a little concerned, because on the wording of the Amendment it might be possible to deal not merely with the method by which evidence is to be given, but also with the person from whom the evidence is to be obtained. However, as I understand that the purpose is entirely directed to the method of giving evidence, and not directed to the person responsible for producing it, so far from seeing any objection to the Amendment, I welcome it.
