Legal Principles
On an appeal against a national security certificate, the Tribunal may only quash the certificate if, applying the principles of judicial review, the Minister did not have reasonable grounds for issuing it.
Section 28(5) DPA 1998
In national security cases, due weight must be given to the assessment and conclusions of the Secretary of State, who is best placed to judge what national security requires.
Secretary of State for the Home Department v Rehman [2001] UKHL 47
Decisions as to whether something is in the interests of national security are not a matter for judicial decision but are entrusted to the executive.

Inconsistency is not a ground for judicial review.

Outcomes
Appeals dismissed.
The Tribunal found that the SOSNI had reasonable grounds for issuing the certificates. While acknowledging some force in the appellants' arguments regarding prior disclosure, the Tribunal emphasized the SOSNI's entitlement to a wide margin of appreciation in national security matters and her right to adopt a precautionary approach. The Tribunal considered evidence heard in closed session, which supported the SOSNI's assessment of ongoing risks.
