Fiat of D.P.P. before trial

Where by any law, the fiat, authorisation, consent, approval or authority of the Director of Public Prosecutions is required before any prosecution or other action is commenced, it shall be sufficient if such fiat, authorisation, consent, approval or authority is obtained and produced to the court before the commencement of the trial, and nothing in any such provision shall prevent the laying of any information or complaint for an offence, or the issue or execution of a warrant for the arrest of any person in respect of such an offence, or the remanding in custody or on bail of any person charged with such an offence.
