(b) an offence of aiding, abetting, counselling or procuring the commission of murder.
142—Meaning of fresh and compelling evidence
(1) For the purposes of this Part, evidence relating to an offence of which a person is acquitted is—
(a) fresh if—
(i) it was not adduced at the trial of the offence; and
(ii) it could not, even with the exercise of reasonable diligence, have been adduced at the trial; and

(i) it is reliable; and
(ii) it is substantial; and
(iii) it is highly probative in the context of the issues in dispute at the trial of the offence.

143—Meaning of tainted acquittal
For the purposes of this Part, if at the trial of an offence a person is acquitted of the offence, the acquittal will be tainted if—
(a) the person or another person has been convicted (whether in this State or in another jurisdiction) of an administration of justice offence in connection with the trial resulting in the acquittal; and
(b) it is more likely than not that, had it not been for the commission of the administration of justice offence, the person would have been convicted of the offence at the trial.
144—Application of Part
(1) This Part applies whether the offence of which a person is acquitted is alleged to have occurred before or after the commencement of this Part.
(2) This Part does not apply if a person is acquitted of the offence with which the person is charged but is convicted of a lesser offence arising out of the same set of circumstances that gave rise to the charge.
(3) However, this Part does apply in the circumstances set out in subsection (2) if the acquittal was tainted.

(b) it is not reasonably practicable in the circumstances to obtain the consent of the Director of Public Prosecutions before taking the action.

(B) an administration of justice offence that is related to the offence of which the person has previously been acquitted; and
(ii) it is in the public interest for the investigation to proceed; and
