Complaints and objection to medical decision
There are two pathways open to you if you have a complaint or objection about a medical decision, depending on the reason for your dissatisfaction.

The chart below is designed to guide all applicants through the process.
Reconsideration
If you disagree with a decision made by CASA regarding the issuing of your medical certificate or any conditions CASA has placed on your certificate, you can request that your certification be reconsidered using an established process.
Reconsideration, as it is known, is a formal process in which a doctor other than the one who made the initial decision leads the process of decision making.
As part of the reconsideration process, your case will be submitted to a special panel of doctors who will reconsider the request, especially if the initial decision was made by a single individual CASA doctor.
An external consultant will be asked to provide expert advice if the original decision had formerly been referred to CASA’s Complex Case Management panel.
It is important to note that reconsideration of the decision that has been made must be received within 21 days of your notification of the original decision and will require a processing fee of $150.
In addition, the assessment period for a reconsideration period is 10-12 weeks. This is to allow external opinions to be sought if required.
You can find more information about reconsideration in the Civil Aviation Safety Regulations (CASR) Part 67 .190. This fee is payment for the process undertaken to review your case and is in no way a guarantee that the decision made will be any different from the original decision.

Review by Administrative Appeals Tribunal
Anyone affected by a decision made by CASA can apply to the Administrative Appeals Tribunal (AAT) for a review of the decision within 28 days from the date of the original decision.
The AAT is an organisation that reviews a wide range of decisions made by Australian Government ministers, departments, agencies and some other tribunals.
The AAT takes a fresh look at a decision and decides if it should stay the same or be changed. The AAT is independent of the person or organisation that made the decision.
General advice in relation to the services provided by the AAT can be found on their website.
