Sometimes when we've been going through the witnesses and trying to get information about how certain aspects of the nuclear industry work, there have been claims of competitiveness in order to protect some of the information. Could that be applied in clause 52? It's to protect not so much a claimant being embarrassed but a company coming forward and saying that the part of the tribunal they're hearing right now starts to cross over and they're concerned about giving away corporate secrets. Is clause 52 open to that type of interpretation by the chairperson?
