Amy Mannion successfully defended the Home Office against two joined applications for judicial review. The Claimants had both challenged the lawfulness of guidance issued by the Home Secretary as to how she proposes to treat requests to be removed from the UK by those without leave to be here.

It had been argued that the guidance document should have been laid before Parliament in order to be lawful, was in any event vague and uncertain, and ran contrary to the policy and objects of the 1999 Immigration Act. Mr Justice Burnett, hearing the appeal, rejected all these arguments.
