Questione giuridica chiave
Whether the appeal was admissible despite the absence of a valid, topically relevant power of attorney for the federal appeal
Decisione estratta
The appeal could not proceed because the purported representative did not establish valid authority to act before the Federal Tribunal.
Motivazione estratta
The submitted powers of attorney did not relate to this procedure, and the later document came from the first-instance authority rather than from the appellant. The appellant had not provided a proper written or electronic mandate under the LTF.
