Questione giuridica chiave
Whether the zoning reclassification unlawfully infringed the appellants' property rights and was disproportionate.
Decisione estratta
The reclassification was justified by a sufficient public interest in housing development and was not disproportionate, as it did not prohibit building but allowed denser use consistent with planning objectives.
Motivazione estratta
The court accepted the need to realize the cantonal planning concept and found that the alternative proposed by the appellants was not shown to preserve the same housing potential. The measure remained objectively defensible and did not exceed what was necessary.
