Section 29-32.1-12 - Affirmative defenses - Res judicata - Misuse of process1. An application for post conviction relief may be denied on the ground that the same claim or claims were fully and finally determined in a previous proceeding.2. A court may deny relief on the ground of misuse of process. Process is misused when the applicant: a. Presents a claim for relief which the applicant inexcusably failed to raise either in a proceeding leading to judgment of conviction and sentence or in a previous post conviction proceeding; orb. Files multiple applications containing a claim so lacking in factual support or legal basis as to be frivolous.3. Res judicata and misuse of process are affirmative defenses to be pleaded by the state. The burden of proof is also upon the state, but, as to any ground for relief which, by statute or rule of court, must be presented as a defense or objection at a specified stage of a criminal prosecution, the applicant shall show good cause for noncompliance with the statute or rule.
