The suspension provisions of S57 have been deemed by the Federal Court to be 'self executing' and thus require no further determination by a Delegate to bring about the suspension. This means that following service of the Notice – which is incorporated in the letter advising the client of the date and time of the medical appointment – any unreasonable failure to attend automatically enacts the suspension.

A Delegate may however intervene and revoke the 'automatic' suspension if he/she believes the client had a 'reasonable excuse'.
