In a significant judgment delivered on 8 January 2026, the Court of Appeal has allowed the government’s appeal against three orders previously made by the High Court in litigation connected to the Afghan data breach. The case involved the Secretaries of State for Defence, the Home Office, and the Foreign, Commonwealth and Development Office (FCDO) and arises from judicial reviews linked to relocation policies after a serious Ministry of Defence data breach.

Context and High Court Orders
The disputes originated from issues concerning two UK Government programmes: the Afghan Relocations and Assistance Policy (ARAP) and the Afghanistan Response Route (ARR), both affected by a large-scale data breach of Afghan applicants’ personal information. The breach, which was subject to a long‑running superinjunction, had serious implications for secrecy and litigation practice.
In two separate judicial review cases, the High Court accepted that Ministry of Defence officials had provided misleading information to the court due to “serious breakdowns in communication.” Officials’ failure to present a complete and accurate record meant the government could not comply with previously agreed court timetables. The High Court strongly criticised this conduct.
In response, the High Court issued broad case management directions intended to apply to all ARAP‑related High Court cases conducted under closed material procedures. These directions required that any future applications to vary court orders be accompanied by a witness statement from a senior civil servant explaining why compliance with existing directions was no longer feasible.
Separately, in proceedings concerning the ARR policy, the High Court imposed a mandatory order requiring government ministers to “forthwith” prepare a revised policy after finding that the government’s delay in doing so was unacceptable. This followed an earlier judgment in R (CX1 and MP1) v Secretary of State for Defence [2024] EWHC (Admin) 892, which found the policy needed reconsideration.
Court of Appeal’s Decision
On appeal, the Court of Appeal acknowledged the “wholly abnormal” circumstances created by the data breach and the superinjunction, and recognised the High Court’s commitment to justice in highly sensitive litigation. However, the appellate court concluded that the High Court’s orders exceeded its legal powers.
For the two general directions, the Court of Appeal held that the High Court judge lacked jurisdiction to make:
- an order affecting a case not before that judge;
- an order relating to hypothetical future cases that had not yet been commenced; and
- an order directed at the conduct of non‑parties to the proceedings.
The Court emphasised that there is no precedent for imposing prospective orders intended to bind other judges or future litigation outside specific frameworks such as group litigation orders. It noted that even in exceptional circumstances, the High Court’s general directions went beyond proper case management powers.
Regarding the mandatory order on ARR policy, the Court of Appeal held that compelling ministers to adopt a revised policy crossed a fundamental constitutional boundary between judicial and executive functions. The Court also took issue with the lack of advance notice that such an order was being contemplated.
Implications
This judgment reaffirms the limits of judicial power within the UK constitutional framework, particularly in the context of sensitive litigation involving national security and executive decision‑making. While recognising the challenging context of the Afghan data breach and its legal aftermath, the Court of Appeal’s ruling clarifies that judges must not extend their case management authority into areas that affect future cases or governmental policy decisions without clear statutory or procedural basis.
