Question juridique clé
Whether the administrative authority and cantonal court were bound by the final criminal findings on drunk driving and could refuse further evidence.
Solution extraite
The administrative authority could rely on the criminal findings and was not required to rehear a witness to reopen facts settled in the criminal case.
Motifs extraits
A final criminal judgment normally binds the licence authority; departure is possible only in narrow exceptions. The applicant withdrew his criminal objection, so he could no longer relitigate those facts in the administrative procedure.
