Questione giuridica chiave
Whether the revised site data sheet submitted before the cantonal appellate hearing had to be excluded as an inadmissible new allegation.
Decisione estratta
The revised site data sheet could be considered because the antenna plan had to reflect newly identified sensitive-use premises and the opposing parties did not dispute its accuracy.
Motivazione estratta
The court held that, in permit proceedings, the installation must be adapted so that emission limits remain respected even after later-discovered sensitive uses are taken into account. Since the new room in the attic was identified only during the proceedings, accepting the amended data sheet served material truth and procedural economy.
