Questione giuridica chiave
Whether the cantonal administrative court had jurisdiction over the termination of the land-use relationship.
Decisione estratta
The administrative court did have jurisdiction because the post-1994 arrangement was correctly characterized as a public-law concession for special use, not as a purely private-law surface right.
Motivazione estratta
The 1994 exchange of letters related to use of public common land in a protected area, required authorization under the consortial regulations, and expressly referred to a concession fee; any contractual elements remained subject to public law. The asserted private-law renewal was unsustainable because the original surface rights had expired and the alleged renewal lacked the required authentic form and land-register effects.
