provide that a certificate signed by a Minister of the Crown certifying that the disclosure of information to the public would, or would be likely to, adversely affect national security is conclusive evidence of that fact;
provide that such a certificate may identify the information to which it applies by means of a general description and may be expressed to apply to information within that description that comes into existence after the certificate is made;
confer other functions on a Minister of the Crown or any other specified person or body (and a function conferred may, in particular, be a power or duty to exercise a discretion).
