Under section 4(3) FSG, the authority must order remedial training after a serious offence during the probationary period. As a rule, it must wait until the penalty for that offence is final. The statute contains a specific exception for the offence in section 4(6)(2a) after an on the spot fine has been issued.
Start with the conclusion of the underlying proceedings. A report or request for observations is not yet a final penalty. Depending on the procedural route, the relevant material may be a summary penalty notice, an administrative penal decision or a court decision together with service and finality records.
