Question juridique clé
Whether the appellant had standing to challenge the partial execution order in mutual legal assistance proceedings.
Solution extraite
He lacked standing because he was not personally and directly affected by the Swiss assistance measure; he was only indirectly concerned as the foreign criminal suspect.
Motifs extraits
Under Arts. 21(3), 80g(1), and 80h(b) EIMP, only a person personally and directly affected by the assistance measure may appeal. Being merely the foreign criminal suspect is insufficient, even if the measure advances the foreign prosecution.
