Questione giuridica chiave
Whether ASLOCA's denunciation had to be treated as anonymous under Art. 10A LPA/GE
Decisione estratta
The complaint was not anonymous because the author signing the denunciation was identified; the authorities were therefore entitled to act on it.
Motivazione estratta
The cantonal court's approach was not arbitrary: Art. 10A LPA/GE bars only anonymous denunciations, and the Department could rely on a letter signed by a known lawyer even if the underlying informants remained unnamed.
