My understanding of the subamendment is that if they were provided confidential information, they could use it only for the purpose of the activity of arbitration and, practically speaking, there would have to be some mechanism limiting their further disclosure. I suspect that would be something like a non-disclosure agreement signed between the CRTC, for example, and those arbitration panel members, but they would be bound not to further disclose or use that information in any other context.
