It does not fall within the powers of the Court of Appeal to calculate the sentence to be served following the granting of extradition. The judicial review that judges are called upon to carry out, in the case of an extradition request, is in fact limited to verifying the existence of the legal requirements and the absence of grounds preventing the acceptance of the request, without being able to modify or adapt the foreign enforcement title. The determination of the sentence to be executed for the offences for which extradition is granted is an exclusive prerogative of the requesting State, entrusted to the institutional responsibility of that country’s judicial authorities and not to those of the requested State.
