Question juridique clé
Whether the foreign representative was authorized to act before the Federal Tribunal
Solution extraite
The representative did not prove lawyer status and did not show any treaty authorizing representation before the Federal Tribunal.
Motifs extraits
Non-EU/EFTA lawyers may appear only if an international treaty so allows; here no such proof or treaty was shown. The court did not give a curative deadline because the appeal was inadmissible for other reasons anyway.
