## ARA.MED.255 Enforcement measures

If, during oversight or by any other means, evidence is found showing a non-compliance of an AeMC, an AME or a GMP, the competent authority shall have a process to review the medical certificates issued by that AeMC, AME or GMP and may render them invalid, where required, to ensure flight safety.

For medical certificates issued to applicants who have a [licensing authority](https://avioverse.aero/glossary/easa/licensing-authority) different from the competent authority that issued the AME certificate, that competent authority shall inform and exchange relevant information with the medical assessor of the licensing authority of the affected medical certificate holder.
