Kernrechtsfrage
Whether the appeal was admissible against the challenged decision
Extrahierter Entscheid
The appeal was admissible; the Court treated the matter as at least a challengeable intermediate decision under Art. 93(1)(b) BGG because an allowance would end the numbering dispute immediately.
Extrahierte Begründung
A finding against shared use would make further proceedings on the common use of the short number unnecessary and avoid substantial further effort.
