Key legal question
Whether the French-language procedural rules made the fund's German-written appeal inadmissible
Extracted holding
No; the federal procedure was conducted in French and the German appeal brief was admissible because it was filed in an official language.
Extracted reasoning
The applicable language provisions lead to French as the language of the proceedings in this case, and an appeal brief itself is not part of the formal conduct of proceedings if filed in an official language.
