Questione giuridica chiave
Whether the mislabeled constitutional complaint should be treated as a civil appeal and is admissible against an incidental recusal decision.
Decisione estratta
The filing is treated as a civil appeal; the decision on recusal was immediately appealable and the value threshold was met.
Motivazione estratta
The Federal Tribunal checks admissibility ex officio. Although the recourant used the wrong label, the challenged decision concerned recusal in a civil monetary dispute and therefore fell under the ordinary civil appeal route, which excludes the subsidiary constitutional complaint.
