Questione giuridica chiave
Whether the road planning restrictions amounted to material expropriation requiring compensation.
Decisione estratta
The south-western part of parcel 109 was effectively deprived of its previous buildability; this constituted material expropriation requiring full compensation.
Motivazione estratta
Although the cantonal rule excluded compensation for ordinary building restrictions, the property guarantee applies where the restriction is equivalent to expropriation. Here the planned road left too little usable land for building, so the loss was compensable.
