4(1)If a person is aggrieved by a scheme adopted by a body under this Schedule and he wishes to question its validity on the ground that it is not within the powers conferred by this Schedule, or that any requirement of this Schedule has not been complied with, he may within the period of six weeks commencing with the first publication (whether in the London or Edinburgh Gazette or otherwise) under paragraph 3(8) above make an application under this paragraph to the High Court or, if the scheme relates to an area in Scotland, the Court of Session.E+W+S
(2)On such an application the High Court or the Court of Session, if satisfied—
(a)that the scheme is wholly or to any extent outside the powers conferred by this Schedule, or
(b)that the interests of the applicant would be substantially prejudiced by the failure to comply with any requirement of this Schedule if an order were made under this Schedule designating the area to which the scheme relates as an enterprise zone,
may order that the Secretary of State shall not make an order under this Schedule designating the area as an enterprise zone in pursuance of the scheme, but (in a case where sub-paragraph) (b) above applies) may further order that, if steps are taken to comply with the requirement concerned, an order may be made designating the area.
(3)No order made by the Court under sub-paragraph (2) above prejudices the making of an order under this Schedule designating the area as an enterprise zone in pursuance of another scheme (so long as this Schedule is complied with).
(4)Except as provided by this paragraph, the validity of a scheme adopted under this Schedule shall not be questioned in any legal proceedings whatsoever.
