Key legal question
Whether the continued abstinence condition and medical controls after methadone treatment were lawful
Extracted holding
The abstinence condition remained justified because methadone treatment still reflected a dependency relevant to fitness to drive; however, the control interval had to be lengthened.
Extracted reasoning
While the condition itself was proportionate and necessary to secure driving fitness, six-monthly checks were no longer proportionate after the completed three-year monitoring period. Annual controls for at least two years were sufficient and consistent with medical recommendations.
