Questione giuridica chiave
Whether the SIX arbitration tribunal had jurisdiction based on the exchange listing rules alone
Decisione estratta
No. Article 62(2) of the listing rules could not replace the statutory appeal path under the Stock Exchange Act or create erga omnes jurisdiction for the tribunal.
Motivazione estratta
The exchange lacked legislative power to alter the route fixed by Articles 8 and 9 BEHG. The statute exhaustively regulates the internal appeal instance and subsequent action before the civil judge; a rule of the exchange cannot substitute a written arbitration agreement.
