Rule 3:22-4. Bar of Grounds Not Raised in Prior Proceedings; Bar of Second or Subsequent Petitions; Exceptions

(a) First Petition for Post-Conviction Relief Any ground for relief not raised in the proceedings resulting in the conviction, or in a post-conviction proceeding brought and decided prior to the adoption of this rule, or in any appeal taken in any such proceedings is barred from assertion in a proceeding under this rule unless the court on motion or at the hearing finds :

(1) that the ground for relief not previously asserted could not reasonably have been raised in any prior proceeding; or

(2) that enforcement of the bar to preclude claims, including one for ineffective assistance of counsel, would result in fundamental injustice; or

(3) that denial of relief would be contrary to a new rule of constitutional law under either the Constitution of the United States or the State of New Jersey. A ground could not reasonably have been raised in a prior proceeding only if defendant shows that the factual predicate for that ground could not have been discovered earlier through the exercise of reasonable diligence. A denial of relief would be contrary to a new rule of constitutional law only if the defendant shows that the claim relies on a new rule of constitutional law, made retroactive to defendant's petition by the United States Supreme Court or the Supreme Court of New Jersey, that was unavailable during the pendency of any prior proceedings.

(b) Second or Subsequent Petition for Post-Conviction Relief A second or subsequent petition for post-conviction relief shall be dismissed unless:

(1) it is timely under R. 3:22-12(a)(2); and

(2) it alleges on its face either:

(A) that the petition relies on a new rule of constitutional law, made retroactive to defendant's petition by the United States Supreme Court or the Supreme Court of New Jersey, that was unavailable during the pendency of any prior proceedings; or

(B) that the factual predicate for the relief sought could not have been discovered earlier through the exercise of reasonable diligence, and the facts underlying the ground for relief, if proven and viewed in light of the evidence as a whole, would raise a reasonable probability that the relief sought would be granted; or

(C) that the petition alleges a prima facie case of ineffective assistance of counsel that represented the defendant on the first or subsequent application for post-conviction relief.
