Shields-McKinley v. The Secretary of State for Justice
 Q.B. 521
Appeared on behalf of the Secretary of State for Justice in the Court of Appeal.
The Appellant appealed against the decision of Mr Justice Holroyde (as he then was) in finding that the prison was not under a duty to credit days spent in custody whilst awaiting extradition, absent a direction from the Court.
The Court of Appeal dismissed the challenge, whilst providing useful guidance on the availability of the Royal Prerogative of Mercy in such circumstances.
