Kernrechtsfrage
Whether the violation of the right to be heard required annulment of the licence withdrawal decision.
Extrahierter Entscheid
The procedural defect did not lead to annulment because the cantonal administrative court had full review powers and was not bound by the parties' reasoning.
Extrahierte Begründung
A hearing defect can be cured in appeal proceedings where the reviewing court may examine the matter freely and the appellant could be heard effectively before that court.
