3:22-4. Bar of Grounds Not Raised in Prior Proceedings; Exceptions

Any ground for relief not raised in a prior proceeding under this rule, or 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 (a) that the ground for relief not previously asserted could not reasonably have been raised in any prior proceeding; or (b) that enforcement of the bar would result in fundamental injustice; or (c) that denial of relief would be contrary to the Constitution of the United States or the State of New Jersey.
