Part 9: Miscellaneous and general provisions Chapter 1: Miscellaneous Section 256: Variation and revocation of notices
This section requires the Secretary of State to keep a technical capability notice or national security notice under review. It allows the Secretary of State to vary or revoke a notice, but only if the variation is necessary and the conduct as varied is proportionate to what is sought to be achieved. If the variation would impose further requirements on an operator, the decision to vary a notice must be approved by a Judicial Commissioner.
	Where Judicial Commissioner approval is required, subsection (8) means that the Commissioner employs the same test as when deciding whether to approve a decision to give a notice. Subsection (9) means that the obligations to consult operators and to take certain matters into account apply when varying a notice as they do when giving a notice.
