(a) Preclusion. A defendant is precluded from relief under Rule 32.1(a) based on any ground:

(b) Claims Not Precluded. Claims for relief based on Rule 32.1(b) through (h) are not subject to preclusion under Rule 32.2(a)(3), but they are subject to preclusion under Rule 32.2(a)(2). However, when a defendant raises a claim that falls under Rule 32.l(b) through (h) in a successive or untimely post-conviction notice, the defendant must explain the reasons for not raising the claim in a previous notice or petition, or for not raising the claim in a timely manner. If the notice does not provide sufficient reasons why the defendant did not raise the claim in a previous notice or petition, or in a timely manner, the court may summarily dismiss the notice. At any time, a court may determine by a preponderance of the evidence that an issue is precluded, even if the State does not raise preclusion.
