Question juridique clé
Whether the cantonal decision was appealable under Art. 93 LTF
Solution extraite
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.
Motifs extraits
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.
