“There is no entitlement to a passport. The decision to issue, withdraw or refuse to issue a British passport is a matter for the Secretary of State for the Home Department (the Home Secretary). On behalf of the Home Secretary, the Minister of State for Immigration and Security considers that it is not in the public interest that you should hold a passport. You are a British national who is involved in terrorism-related activity. It is assessed that you are likely to travel overseas in future in order to engage in terrorism-related activity. You were deported from Bulgaria to the UK on national security grounds in November 2014. It is assessed that these activities would present a risk to the national security of the United Kingdom. You are therefore considered a person whose past, present or proposed activities, actual or suspected, are so undesirable that the grant or continued enjoyment of passport facilities is believed to be contrary to the public interest. The passport remains the property of the Crown and Her Majesty’s Passport Office requests that you return the passport to the police officer delivering the letter. It is open to you to apply for a passport at a later date. The issue of a passport will be determined on the circumstances at the time of any application. If you require any further information, please contact Her Majesty’s Passport Office, quoting the above reference number.”
“….the whole purpose of the cancellation of the passport is to prevent XH from leaving the United Kingdom. The interference with XH’s freedom of movement in the EU, if not absolute, is near absolute. A compelling justification is required for such interference.”
"If an applicant for permission to move for judicial review claims that the Secretary of State's decision is vitiated by some form of illegality he will file evidence to that effect. The Court will not shut out evidence which is relevant to the issues. Indeed, it may order disclosure of evidence necessary for disposing fairly of the application. The evidence is not strictly limited to evidence which was or should have been before the Secretary of State at the time of the decision."
