In view of the fact that an application for leave is heard exparte, there is a duty on the part of the Applicant to disclose material facts which would convince the court that leave ought to be granted. The judgment of Tuan Hj Sarip Hamid is particularly instructive as follows: The salutary advice of Dunn LJ in R v Secretary of State for Trade & Ors, ex p Anderson Strathclyde plc [1983] 2 All ER 233 should be kept in the forefront of the mind of any lawyer who drafts the statement for purposes of O 53 r 1(2), and the affidavit in support thereof. What the learned Lord Justice said was this (at p 239f): … Proceedings for judicial review are not designed for detailed enquiry into contested facts. It is for the applicants to take all proper steps to put the facts on which they rely in support of the relief claimed before the court at the first opportunity … Similarly, it is worthwhile for the draftsman to remind himself of what Lord Diplock had said in O'Reilly v Mackman [1983] 2 AC 237 at p 282[1982] 3 All ER 1124 at p 1132[1982] 3 WLR 1096 at p 1107, namely: … The facts … can seldom be a matter of relevant dispute on an application for judicial review, since the tribunal or authority's findings of fact, as distinguished from the legal consequences of the facts that they have found, are not open to review by the court in the exercise of its supervisory powers except on the principles laid down in Edwards (Inspector of Taxes) v Bairstow & Anor [1956] AC 14 at p 36[1955] 3 All ER 48 at pp 57–58) … Having said that, we would add that it is a counsel of prudence for a lawyer drafting his application under O 53 r 1(2) to ensure that it contains substantial particulars of the facts and matters on which he intends to rely in support of his application. He should also ensure that his affidavit in support of his application is as detailed and comprehensive as the circumstances will permit, and it should exhibit all the documentary exhibits which are truly relevant and upon which he intends to rely. The object of these steps is to ensure that the court has as complete a picture as is possible right from the start, of the case for the applicant who is seeking judicial review.
