Questão jurídica principal
Whether the security withdrawal of the driving licence was proportionate without a new medical expert opinion.
Decisão extraída
In the special circumstances of the case, a less severe measure was possible: the monitoring period should have been extended while keeping the licence.
Fundamentação extraída
No convincing sign of ongoing drug dependence existed after the medical follow-up; the failure to meet the deadline was due to negligence, not relapse or refusal. Proportionality required extending the urine-testing and medical-monitoring regime rather than withdrawing the licence.
