Adding further as I’ve dug a bit more: NSICOP members are uniquely restricted by virtue of their enabling statute. They specifically are unable to claim parliamentary privilege to disclose classified information learned in the course of NSICOP duties; that was upheld in the court case from a few years ago that I mentioned. However, this only applies to members of the committee. I cannot speak to how other Parliamentarians would see SOIA balance with parliamentary privilege. This provision of the NSICOP enabling legislation is, I suppose, part of the balance of allowing a general committee of Parliamentarians to access this material in the first place, beyond the right circle of those who would have access by virtue of, eg, cabinet roles.
