Healy and Civil Aviation Safety Authority

This matter concerned an appeal by Mr Healy against a decision by the Civil Aviation Safety Authority (CASA) to refuse him a Class 1 or Class 2 medical certificate. The central dispute revolved around Mr Healy's diagnosis of Attention Deficit Hyperactivity Disorder (ADHD) and his treatment with dexamphetamine. The Tribunal was required to determine whether Mr Healy met the relevant medical standards, and if not, whether his condition posed a risk to air navigation safety, and if so, whether any conditions could mitigate that risk.

The legal issues before the Tribunal were threefold. First, it had to ascertain whether Mr Healy met the prescribed medical standards for a Class 1 or Class 2 medical certificate. Second, if he did not meet these standards, the Tribunal was required to assess whether the extent of his failure was likely to endanger the safety of air navigation. Third, and crucially, if a risk to air safety was identified, the Tribunal had to determine whether any conditions could be imposed on a medical certificate that would effectively ameliorate that risk.

The Tribunal's reasoning was guided by section 9A of the Civil Aviation Act, which mandates that the safety of air navigation must be the paramount consideration. It found that Mr Healy did not meet the medical standards due to his established diagnosis of ADHD and his ongoing reliance on dexamphetamine. The Tribunal further determined that this failure to meet the standards was likely to endanger air navigation safety. Critically, after considering the nature of Mr Healy's condition and the medication used to manage it, the Tribunal concluded that no conditions could be imposed on a medical certificate that would sufficiently ameliorate the identified threat to air safety. Consequently, the Tribunal affirmed CASA's decision to refuse the medical certificate.
