DLR HOLDINGS LIMITED & ANOR (R on the application of) v YORK MAGISTRATES’ COURT & ANOR

At the permission stage of judicial review, the court determines arguability rather than the merits. Where alleged defects in the application for a warrant may have vitiating consequences for the warrant itself, the issuing court may properly be joined as a defendant. The court may retain the claim in the Administrative Court where the grounds are suitable for judicial review, there are no disputed primary facts requiring oral evidence, and questions of materiality can be resolved within the judicial review. Issues concerning execution which are not linked to the judicial review grounds may be postponed for later determination.

The claimants challenged two warrants issued by York Magistrates’ Court on an application by the Environment Agency and their subsequent execution. A judge granted permission on three grounds concerning the Agency’s application, evidence and disclosure, but only against the Agency. Permission was refused on three further grounds concerning the wording of the warrants, and the claim was provisionally directed to be transferred to the Queen’s Bench Division because of possible factual disputes.

On renewal, the claimants challenged the refusal of permission and sought reconsideration of the transfer direction. The issues were whether the Magistrates’ Court should be joined in relation to the granted grounds, whether the renewed grounds were arguable, and whether the claim should remain in the Administrative Court.

1. Permission and joinder. The court did not revisit the judge’s decision that the first group of grounds was arguable. The alleged deficiencies in the Agency’s application and disclosure could, if established and material, have a vitiating effect on the warrants issued by the Magistrates’ Court. Permission therefore had to include the Magistrates’ Court as a defendant, since the remedies sought directly impugned the warrants.
2. Renewed grounds. The three grounds concerning the wording of the warrants crossed the threshold of arguability. They raised substantial questions about the relationship between the warrants, the underlying legislation and the applications placed before the magistrates. They also raised questions about stand-alone intelligibility, the significance of allegedly inappropriate wording, the specificity of the investigation, and the distinction between searching, examining, inspecting and investigating. No authority relied on by the Environment Agency constituted a decisive answer at the permission stage.
3. Forum. Although warrant claims and execution issues may appropriately be transferred to the Queen’s Bench Division, the complexion of this case had changed. The Administrative Court was capable of addressing the six grounds for which permission now existed. There was no disputed primary fact requiring oral evidence, nor any factual issue beyond the court’s capacity to determine. Questions of materiality were familiar judicial review questions.
4. The provisional transfer order and proposed case management conference in the Queen’s Bench Division were discharged. The claim was retained in the Administrative Court. Any execution issues not linked to the judicial review grounds, such as whether execution exceeded the warrants’ authority, were postponed for consideration at an appropriate stage.

• Administrative Court, on paper: HHJ Stephen Davies granted permission on three grounds against the Environment Agency, refused permission on three grounds concerning the warrant wording, and provisionally directed transfer to the Queen’s Bench Division.
• High Court (Administrative Court): On renewal, permission was granted on the further three grounds, the Magistrates’ Court was included as a defendant for the existing grounds, and the provisional transfer direction was discharged.
