Questione giuridica chiave
Whether the federal complaint was admissible despite being filed only by fax and without a signed original.
Decisione estratta
No. Fax submissions are invalid; the court exceptionally did not return them for signature because they did not meaningfully address the cantonal decision.
Motivazione estratta
Under the applicable procedural rules, a valid filing requires proper form. The faxed submissions were therefore ineffective.
