57 Validity and effect of orders.E+W+S
(1)If the relevant operator to whom a final or provisional order relates is aggrieved by the order and desires to question its validity on the ground—

he may, within 42 days from the date of service on him of a copy of the order, make an application to the court under this section.
(2)On any such application the court, if satisfied that the making or confirmation of the order was not within those powers or that the interests of the relevant operator have been substantially prejudiced by a failure to comply with those requirements—
(a)may quash the order or any provision of the order; or
(b)if and to the extent that the application related to so much of an order as imposes a monetary penalty, may substitute a monetary penalty of such lesser amount as the court considers appropriate in all the circumstances of the case.
(3)Except as provided by this section, the validity of a final or provisional order shall not be questioned by any legal proceedings whatever.

(6)In any proceedings brought against a relevant operator in pursuance of subsection (5) above, it shall be a defence for him to prove that he took all reasonable steps and exercised all due diligence to avoid contravening the order.
(7)Without prejudice to any right which any person may have by virtue of subsection (5) above to bring civil proceedings in respect of any contravention or apprehended contravention of a final or provisional order, compliance with any such order shall be enforceable by civil proceedings by the appropriate officer for an injunction or for interdict or for any other appropriate relief or remedy.
(8)Where a relevant operator to whom a final or provisional order relates has made an application pursuant to subsection (1) above questioning the validity of that order, the making of that application shall not affect—
(a)his obligation to comply with the order, or
(b)the right which any person may have to bring civil proceedings against him in pursuance of subsection (5) or (7) above.
