“Judicial review is not a fact finding exercise and it is an extremely unsatisfactory tool by which to determine, in any but the clearest of cases, whether there has been a seizure of material not permitted by a search warrant. In my judgment a person who complains of excessive seizure in breach of section 16(8) should not, save in such cases, seek his remedy by way of judicial review but should rely on his private law remedy when he will have a tribunal which will be able to hear evidence and make findings of fact unfettered by Wednesbury principles. In an appropriate case the court in a private law action is able to grant interlocutory relief on a speedy basis on well recognised principles so that in all but the clearest cases of a breach of section 16(8) judicial review has only disadvantages and no advantages when compared with the private law remedy.”
“We are satisfied that judicial review proceedings are not an appropriate mechanism for resolving the large number of issues of fact as well as law which are likely to arise when determining whether excessive seizures have taken place in the execution of these warrants.”
“45. The Chief Constable and HMRC have a duty to investigate allegations of serious crime, and to do this as thoroughly and as effectively as possible, in the public interest. In this case there was (and is) ample evidence that serious commercial crimes (counterfeiting, VAT fraud and excise fraud on a multi-million pound scale) had been committed. The question was and is as to who had committed them. 46. It is in the public interest that the Defendants should pursue their investigations thoroughly, efficiently and speedily so as to make a report in due course to a prosecutor (in this case RCPO) who can then decide whether criminal proceedings should be instituted, in accordance with the Code for Crown Prosecutors. 47. The Claimants are seeking the exercise of a judicial discretion to interfere in an ongoing and incomplete criminal investigation, in a way that will necessarily impede it. 48. Injunctive relief is neither necessary nor convenient – the scanning exercise that is in place is a straightforward and workable process that does not require judicial intervention save as a last resort, and then in the more appropriate and cost-effective jurisdiction of the Crown Court. 49. The Claimants’ private interest (that the police should not have access to potentially incriminating material until after their civil action is determined) is outweighed by the greater public interest.”
