Question juridique clé
Whether the federal appeal was admissible despite the cantonal court having rejected the appeal for lack of a valid power of attorney.
Solution extraite
The federal appeal was admissible; the challenged decision fell within the mutual legal assistance framework and constitutional grievances could be raised.
Motifs extraits
Because the measure was taken in execution of a Pakistani mutual assistance request under the EIMP, only the administrative-law appeal was open. The appellant could invoke constitutional rights in that framework.
