Key legal question
Whether a cantonal investigating judge executing foreign mutual legal assistance acts as a federal officer under Art. 1(1)(f) VG.
Extracted holding
No. Mutual legal assistance execution is generally a cantonal task under the IRSG; Art. 1(1)(f) VG does not make the Confederation primarily liable for cantonal acts.
Extracted reasoning
Art. 1 VG expands the Act's scope, not the Confederation's primary liability. Even if a cantonal authority is directly entrusted with a federal task, liability normally lies first with the canton or organization concerned, with federal liability only subsidiary. In mutual legal assistance, cantonal authorities execute the request under federal supervision but do not perform a federal task.
