28.These sections require the CAA to make orders that will be binding on a licence holder where the licence holder is contravening, or is likely to contravene, a duty under section 8 or a licence condition. Section 20 requires the CAA, subject to the exceptions in section 21, to make a provisional order when it appears to it that there is or is likely to be a contravention of a duty under section 8 or a licence condition, and to make a final order, or to confirm a provisional order, where it is satisfied that there is or is likely to be a contravention of a duty under section 8 or a licence condition. Section 21 gives the CAA a discretion to make or confirm a provisional order or confirm a final order, if it thinks appropriate in certain circumstances. Section 22 sets out the procedural requirements to be observed before making a final order or confirming a provisional order. If the licence holder wishes to question the validity of a final or provisional order relating to it, it may do so under section 23. Section 24 requires any licence holder to which a final or provisional order relates to comply with it. This duty to comply with the order is owed to any person who may be affected by a contravention of the order and breach of the duty is actionable by him.
29.Section 25 provides the CAA with a power to obtain information in cases where it appears to the CAA that a licence holder may have contravened, may be contravening, or is likely to contravene a licence condition.
