“The question is not whether the Secretary of State himself thinks that the new claim is a good one or should succeed, but whether there is a realistic prospect of an adjudicator, applying the rule of anxious scrutiny, thinking that the applicant will be exposed to a real risk of persecution on return … The Secretary of State of course can, and no doubt logically should, treat his own view of the merits as a starting point for that enquiry: but it is only a starting point for the consideration of a question that is distinctly different from the exercise of the Secretary of State making up his own mind. Second, in addressing that question, both in respect of the evaluation of the facts and in respect of the legal conclusions to be drawn from these facts, has the Secretary of State satisfied the requirement of anxious scrutiny? If the Court cannot be satisfied that the answer to both of those questions is in the affirmative, they will have to grant an application for review of the Secretary of State’s decision.”
