Questione giuridica chiave
Whether the disciplinary sanction was time-barred.
Decisione estratta
The sanction was subject to administrative prescription; the court held that the sanction was prescribed under the applicable administrative time limit.
Motivazione estratta
The case involved not only a cantonal contravention but also a federal one, so the prescription rules of administrative law applied rather than a criminal-law prescription derived from cantonal law.
