PARKER and DIRECTOR GENERAL OF TRANSPORT

The case of Parker v Director General of Transport involved the applicant, who held multiple driver's licences, including MR and HR class licences, which allowed him to operate medium and heavy trucks. The Director General of Transport sought to suspend these licences based on the applicant's medical conditions and treatment, asserting that they could impair his ability to control a motor vehicle. The matter was heard and determined by the Administrative Appeals Tribunal (AAT).

The central legal issues revolved around the interpretation of statutory provisions that permit the Director General to suspend or refuse a licence if there is a reason to believe that the applicant's ability to control a motor vehicle is impaired due to a medical condition or treatment. Specifically, the Tribunal had to determine whether the Director General could rely on a belief or decision made by another person to exercise the statutory power and whether the Director General was required to assess the particular licence holder's condition in relation to any possible impairment.

The Tribunal found that the Director General could not exercise the statutory power by adopting another person's belief or decision. Instead, the Director General must form an independent belief about the licence holder's condition and its potential impact on their ability to control a vehicle. The Tribunal emphasised that the prescribed belief must relate directly to the licence holder and their specific circumstances, rather than general conditions or treatments. As such, the Tribunal held that the Director General's decision was flawed because it did not properly assess the applicant's individual circumstances and condition.

The Tribunal quashed the decision of the Director General and remitted the matter back for reconsideration in light of the Tribunal's findings. The Tribunal's decision underscored the importance of an independent assessment of the licence holder's condition and its potential impact on their driving ability, rather than relying on generalised beliefs or decisions made by others.
