Questione giuridica chiave
Whether the Neuchâtel supervisory authority could entertain a complaint seeking to declare null a payment order issued by a Bern office.
Decisione estratta
The complaint was untimely insofar as it sought nullity of the Bern payment order before the Neuchâtel supervisory authorities.
Motivazione estratta
Nullity may be raised at any time, but only before the competent supervisory authority. A Neuchâtel authority cannot materially supervise an act carried out by a Bern office.
