Questione giuridica chiave
Whether the cantonal court violated the right to be heard by not addressing the absence of a legal basis for the temporary speed limit.
Decisione estratta
No violation occurred; the court implicitly accepted the validity of the signalisation and the point had already been resolved in the related criminal case.
Motivazione estratta
A court may confine itself to the essential reasons; it need not refute every argument explicitly. The earlier Federal Supreme Court judgment had already confirmed the validity of the reduced limit.
