“26. It will be convenient for the Administrative Court office to indicate that a question of stay may arise for consideration in a given case, and refer the matter to a judge. 27. The question of a stay should then be considered by a judge alongside the application for permission. The question is whether the outcome of any appeal in [the lead case] is likely to be decisive…If such a different outcome is likely to be decisive or determinative in a given case, then it may be appropriate to conclude the interests of justice require a stay. If not, not. 28. In any case where a stay is ordered, it seems to me likely that a judge will adjourn the question of permission. If the outcome of any appeal to the Supreme Court is properly to be regarded as potentially decisive, it would seem unlikely that a judge would be content to grant or withhold permission without knowing the outcome. 29. I am not attracted by the submission that appeals should be progressed on other grounds, leaving open an application to stay if the appeal fails on those grounds. I understand the objective of avoiding delay, particularly where an applicant may be detained but such an approach would add much time and cost. In my view, the better approach is either to proceed or to stay where appropriate. 30. In any case where a judge concludes that a stay is the appropriate course, but where the parties have not made submissions on the point, provision should be made for either party to make representations if they wish to do so. This need not be more than an Order that a case will be stayed unless within a specified period either party makes representations in writing opposing a stay, in which case the stay will be reconsidered. 31. I accept that it is a relevant consideration whether the requested person was unrepresented at first instance, and no doubt judges will bear that in mind. 32. The Administrative Court Office will no doubt wish to keep under review any matters stayed pending such prospective appeal, and on a regular basis report to the judge in charge of the Administrative Court”
