Section 71 of the Act says.
“When any person is under commitment upon a charge of an indictable offence against the laws of the Commonwealth, the Attorney-General or such other person as the Governor-General appoints in that behalf may decline to proceed further in the prosecution, and may, if the person is in custody, by warrant under his or her hand direct the discharge of the person from custody, and he or she shall be discharged accordingly.”
The power to drop the unjust prosecutions of David McBride and Richard Boyle lies with you, Mark.
