Questione giuridica chiave
Whether the appeal against the cantonal incidental decision on standing was admissible under Art. 93 LTF.
Decisione estratta
The appeal was inadmissible because, although an immediate final decision would follow if standing were denied, accepting the appeal would not avoid extensive and complex evidence, given the parallel case against the Canton and the need for broad fact-finding anyway.
Motivazione estratta
For incidental decisions, Art. 93(1)(b) LTF requires cumulatively an immediately final decision and avoidance of a defatigating or costly evidentiary procedure. The second condition failed due to the ongoing necessary evidentiary proceedings against the Canton.
