“Application to vary or discharge warrant 9.1 The occupier or person in charge of premises in relation to which a warrant has been issued may apply to vary or discharge the warrant. 9.2 An application under paragraph 9.1 to stop a warrant from being executed must be made immediately upon the warrant being served. 9.3 A person applying to vary or discharge a warrant must first inform the named officer that he is making the application. 9.4 The application should be made to the judge who issued the warrant, or, if he is not available, to another High Court Judge.”
“The approach taken in Rossminster was therefore (i) to treat the onus as being on the applicant for judicial review to establish that the warrant should be quashed and (ii) to treat the applicant as unable to satisfy this onus, in circumstances where the original decision-maker had access to material withheld on public interest grounds from the person affected seeking judicial review; (iii) this result followed from the application of the maxim omnia praesumuntur rite esse acta.”
“The application is made without the opponent’s being notified that it is being made; the court will almost always grant permission unless there is a very obvious flaw in the application. If permission is granted, as in practice it almost always is, and service is effected in accordance with it, the defendant may dispute the jurisdiction by challenging the order which granted permission, and the service which was made pursuant to it, by applying underCPR Part 11 . The inter partes procedure which then follows marks the point in the process at which the court will investigate whether permission to serve should have been granted. The fact that permission was granted to the claimant in the first place is largely irrelevant at this point: it leaves no footprint; no onus is placed upon the defendant who applies to have the permission set aside; the application is in effect a rehearing of an application for permission, with the onus lying on the party who needed the permission in the first place. The court is not inhibited from discharging or varying the order, and for which the claimant now in substance (if not in form) reapplies, by reason of the fact that it has already been made.” 92. However, the question on the re-hearing is whether it was proper to grant permission on the date upon which the order to serve out was granted, not (in the light of changed circumstances or fresh evidence) whether it would be right to grant it as at the time of the inter partes application. In ISC Technologies Ltd v. Guerin [1992] 2 Lloyd's Rep. 430at 434, Hoffmann J. stated: 15. O.12, r.8is a rehearing of the application to the Master and the exercise of a fresh discretion. It should therefore take into account whatever has since happened. I do not agree. The application is under R.S.C. O.12, r.8(1)(c)to discharge the Master's order giving leave to serve out. The question is therefore whether that order was rightly made at the time it was made. Of course, the court can receive evidence which was not before the Master and subsequent events may throw light upon what should have been relevant considerations at the time. But I do not think that leave which was rightly given should be discharged simply because circumstances have changed. That would mean that different answers could be given depending upon how long it took before the application came on to be heard. The position is quite different when the application is for a stay on grounds of forum non conveniens. In such a case, the appropriate time to consider the matter is the date of the hearing.” 93. As Evans L.J. noted in Mohammed v. Bank of Kuwait and the Middle East KSC[1994] 1 WLR 1483 at 1492, “[t]he question for the court is whether the evidence in support of the application justifies the order which is applied for being made. The evidence may be produced then or subsequently, but it must be directed at the situation at the date when the application is made.””
“3. Without enumerating all, or indeed any, of the evidence which has been placed before me, I am satisfied that on the evidence which was placed before me, that the CMA is entitled to carry out its investigation and to seek the documents that it seeks. I am satisfied that it is entitled to a warrant to enter the premises – both business and domestic – in order to secure the documents in question. I am satisfied that there are reasonable grounds for suspecting that if the undertakings concerned were given notice of the requirement to produce documents, there would be a risk of destruction and tampering within the two sections. 4. That conclusion as to the suspicion of risk to the documents arises notwithstanding two factors, which I have borne permanently in mind. The first is that, to an extent, at least two of the undertakings would have had notice of the interest of the CMA in their activities, because the CMA has engaged with those undertakings via notices and objections, and the like. However, those notices were focussed on different types of abuse from those which now primarily concern the CMA and which are used to support the application made to me. A canny operator in those firms may well by now have realised that the CMA was interested and there is a real possibility that if they behave as nefariously as the CMA fears they will become a destroyer of evidence. Nonetheless, the flagging of the interest in the other potential abuses is not sufficient to require the conclusion that whilst there once might have been suspicion of risk of destruction, there no longer can be because the undertakings will have long ago destroyed the incriminating material. I am satisfied there is still a proper degree of likelihood that the documents still exist on the business premises and elsewhere, and that there is a risk of destruction were the CMA to give notice of its intentions and views in advance of securing the documentary material in question. By documents, I mean, of course, both hard copy documents and documents held in digital form”
“The CMA’s investigation has progressed since Concordia provided its response to the CMA’s requests. The CMA now considers that Concordia’s response was incomplete, and suspects that as a result, there remain documents relevant to the Investigation on Concordia’s premises, which have not yet been provided by the CMA. Specifically, the CMA now understands that the methodology proposed by Concordia is likely to have resulted in the following material omissions of relevant documents…”
“Overall, if the information obtained by the CMA is correct, it is reasonable to suspect that the relevant personnel at Concordia who were responsible for managing the response to the CMA’s section 26 notices ought to have know that Concordia’s response to the CMA’s section 26 Notice was incomplete. That said, I am aware that Concordia would argue that it has fully cooperated to date and that it facilitated the CMA’s investigation by assisting the preservation/imaging of the relevant parts of its IT infrastructure by way of imaging in the liothyronine, fusidic acid and carbimazole excessive and unfair pricing investigation (“Project Forest”). Moreover, some (although not all) of the individuals that the CMA considers were omitted in Concordia’s response in relation to hydrocortisone were later included in the documents produced by Concordia in relation to Project Forest.”
