Regulation 54 Restrictions on proceedings pending the conclusion of an investigation
No disciplinary proceedings or administrative action procedures can be brought or initiated in relation to any matter which is the subject of an investigation in accordance with the provisions of this Part until—
a report on that investigation has been submitted to the Commissioner or to the appropriate authority under regulation 56 or 60; or
where under regulation 36 the Commissioner has personally carried out the investigation, a report has been completed by the Commissioner.
The restrictions imposed by this regulation in relation to the bringing of disciplinary proceedings do not apply to the bringing of proceedings by the appropriate prosecutor in any case in which it appears to the prosecutor that there are exceptional circumstances which make it undesirable to delay the bringing of such proceedings.
