Questão jurídica principal
Whether the cantonal appeal against the first licence-withdrawal decision had become moot after the later modifying decision.
Decisão extraída
The appeal could be treated as moot as to the withdrawal period because the later decision replaced the earlier one on that point.
Fundamentação extraída
The authority did not fully withdraw the first decision but modified it. The modified duration could be challenged by ordinary appeal, so the cantonal court could regard the appeal against the first decision as without object.
