This section applies if at any time in the relevant period the Supreme Court is informed by the designated authority that a Part 1 warrant issued in respect of a person has been withdrawn.
The relevant period is the period—
starting when leave to appeal to the Supreme Court is granted to the person or the authority which issued the warrant;
ending when proceedings on the appeal are discontinued or the Supreme Court makes its decision on the appeal.
If the appeal is brought by the person in respect of whom the warrant was issued the Supreme Court must—
order the person's discharge;
quash the order for his extradition, in a case where the appeal was against a decision of the High Court to dismiss an appeal under section 26.
If the appeal is brought by the authority which issued the warrant the Supreme Court must dismiss the appeal.
If the person is not before the Supreme Court at the time it orders his discharge, the Supreme Court must inform him of the order as soon as practicable.
