Questione giuridica chiave
Whether the public law appeal was admissible against an international administrative assistance decision, including the recusal ruling on the panel.
Decisione estratta
The appeal was inadmissible because Art. 83 letter h LTF excludes public law appeals in international administrative assistance matters, including incidental procedural rulings.
Motivazione estratta
The exclusion ground covers both the merits and procedural aspects under the unity of proceedings; a separately issued interlocutory decision is also barred from ordinary appeal.
