Questione giuridica chiave
Whether the cantonal decision was appealable under Art. 93 LTF
Decisione estratta
The decision was an incidental ruling on a substantive preliminary issue and was only reviewable if the conditions of Art. 93(1)(b) LTF were met.
Motivazione estratta
It was not a final decision and did not fall under Art. 92 LTF. Although an immediate federal ruling could end the case if standing were denied, the appellant failed to show that immediate admission would avoid a long and costly evidentiary procedure.
