Question juridique clé
Whether the appeal against the interlocutory order requiring a Swiss service address is admissible.
Solution extraite
The appeal is inadmissible because the appellant failed to show a non-reparable legal disadvantage and no such disadvantage is apparent.
Motifs extraits
The challenged order concerns only service arrangements and is an appealable interim decision only under Art. 93(1) BGG. No irreparable harm was substantiated under Art. 42(2) BGG; publication in the Federal Gazette did not disclose any evident irreparable disadvantage, and the appellant could designate a service recipient directly without traveling to Switzerland.
