Question juridique clé
Whether the preventive withdrawal of the driving licence was justified pending clarification of aptitude to drive.
Solution extraite
Yes. Serious doubts about driving aptitude existed, so preventive withdrawal was permissible until the expert investigation clarified the exclusion grounds.
Motifs extraits
A blood alcohol level of at least 2.5‰ triggers an aptitude examination; the medical findings, abnormal liver markers and the expert's unresolved concerns created concrete indications of possible alcohol dependence. The appellant refused further required examinations, so the doubts were not dispelled.
