Thanks for the links.
I never thought he had much chance for an appeal and probably his lawyers knew that too. It was probably a face saving thing.
As for the 'discount', does this mean that he will be on the hook for most of the legal costs? I hope so, as this was taxpayers' money. Even with a 'discount', it will be well into the hundreds of thousands. Was it worth it? Even if the Judicial Review had been successful, all that would have happened is that his file would be returned to the Home Office for review. And as the judge said, it's highly likely they'd have come to the same decision all over again.
