The Director shall issue a Code for Crown Prosecutors giving guidance on general principles to be applied by them—
in determining, in any case—
whether proceedings for an offence should be instituted or, where proceedings have been instituted, whether they should be discontinued; or
what charges should be preferred; and
in considering, in any case, representations to be made by them to any magistrates' court about the mode of trial suitable for that case.
The Director may from time to time make alterations in the Code.
The provisions of the Code shall be set out in the Director's report under section 9 of this Act for the year in which the Code is issued; and any alteration in the Code shall be set out in his report under that section for the year in which the alteration is made.
