Questão jurídica principal
Whether serious doubts about the appellant's fitness to drive justified a medical examination and possible preventive licence withdrawal.
Decisão extraída
Yes. The long-standing, regular and likely high cannabis consumption, combined with a prior drug-driving conviction, created concrete indications of possible unfitness to drive.
Fundamentação extraída
The Court held that an examination may be ordered when concrete indications raise serious doubts, even without proof of driving under the influence or carrying drugs in a vehicle. The appellant's contradictory statements did not dispel the doubts.
