18B. — (1) Without prejudice to the generality of sections 4 and 15, where the Authority is of the opinion that a person—

(a) is contravening a relevant provision, or

(b) has contravened a relevant provision in circumstances that make it likely that the contravention will continue or be repeated,

then the Authority may serve on the person a notice in writing, accompanied by a copy of this Part—

(i) stating that it is of that opinion,

(ii) specifying the relevant provision as to which it is of that opinion and the reasons why it is of that opinion,

(iii) directing the person to take such steps as are specified in the notice to remedy the contravention or, as the case may be, the matters occasioning it, and

(iv) specifying a period (ending not earlier than the period specified in section 18C(1) within which an application under that section against any direction specified in the notice may be made) within which those steps must be taken, being a period reasonable in the circumstances.

(2) The steps specified in an enforcement notice to remedy any contravention or matter to which the notice relates may be framed so as to afford the person on whom it is served a choice between different ways of remedying the contravention or matter, as the case may be.

(3) Where a person on whom an enforcement notice has been served makes an application under section 18C(1) against any direction specified in the notice, the steps specified in the notice need not be taken by the person pending the determination, withdrawal or abandonment of the application.

(4) The Authority may cancel an enforcement notice by notice in writing served on the person concerned.

(5) Where a person fails to take the steps specified in an enforcement notice served on the person, the Authority may, on notice to that person, apply in a summary manner to the High Court for an order requiring the person to take those steps (or to take such varied or other steps for the like purpose as may be specified in the order), and the Court—

(a) may—

(i) make the order sought,

(ii) make the order sought subject to such variations to those steps as may be specified in the order, or

(iii) make the order sought subject to such other steps for the like purpose as may be specified in the order, or

(b) may dismiss the application, and, whether paragraph (a) or (b) is applicable, may make such order as to costs as it thinks fit in respect of the application. Application for cancellation of direction specified in enforcement notice.]
