It is instructive to reproduced the relevant paragraphs from Sundra Rajoo (supra) for purposes of this application: “[109] That said, we accept that at stake in all review cases is the notion that the courts must be cautious not to run awry of the fine dividing line of the doctrine of separation of powers. In this regard, while the AG/PP's powers are reviewable, the AG/PP's discretion under art. 145(3) of the FC, as a matter of policy, remains subject to a higher threshold of scrutiny. … [112] Article 145(3) of the FC provides the AG/PP with a wide discretion to institute, conduct or discontinue any proceeding for a criminal offence. This wide discretion means the AG/PP has sole and exclusive discretion in that only he/she can exercise such power. However, the AG/PP does not have absolute or unfettered discretion under art. 145(3).

[113] In all challenges against the decisions of the AG/PP exercising his powers under art. 145(3) of the FC, the position is that his decisions are cloaked with the presumption of legality. The onerous burden lies on the challenging party to overcome the strong presumption of legality with compelling prima facie evidence of grounds to review the AG/PP's decision within the recognised reasons for judicial review.

This refers to the traditional grounds of judicial review and other bases implicitly recognised by the earlier judgments on this subject, including but not limited to:
