There are different levels of security that are assigned to documents. Documents that go to cabinet, memorandums to cabinet, are subject to the confidence of the Queen's Privy Council.
In terms of the development of legislation, as I indicated in my remarks, people that are considered involved and that have security clearances would be employees that are responsible for the developing of the policy and the proposal, in this case to myself as the minister, the ministerial department, and department staff, and personnel that support me in terms of making particular policy choices, central agency employees who advance the policies and the proposals brought forward by departments of supporting ministers, and legal advisers providing advice on the policy on the proposals and the issues that are subject to cabinet discussion.
All of those documents that contribute toward that are marked as subject to the confidence of the Queen's Privy Council and are secret documents. In order to review and participate in those documents, you have to have a high level of security clearance.
