Questione giuridica chiave
Whether the cantonal department's non-entry decision lacked a reviewable object because no formal demonstration request or decision existed.
Decisione estratta
The courts could validly hold that no formal request and no formal refusal had been made; the department therefore had no appealable decision before it.
Motivazione estratta
Given the prior police warnings and the applicant's own decision not to submit a written request, it was not arbitrary to treat the matter as lacking a formal administrative act; requiring a written and clear request was justified to preserve reviewability.
