Whether the federal appeal against the cantonal decision was admissible despite its incidental nature.
The appeal was admissible because the challenged decision caused an irreparable legal harm: once the respondent accessed the CD, the disclosed information could not be undone.
The Court applied Art. 93(1)(a) LTF and held that the decisive issue is the effect of the first-instance order on the continuation of the proceedings, not the cantonal inadmissibility ruling. Disclosure of confidential information is irreversible.
