Rule 25.3 - Responsibilities of the Trial Judge(a) The judge shall not participate in plea discussions.(b) If a plea agreement has been reached which contemplates entry of a plea of guilty or nolo contendere in the expectation that the charge or charges will be reduced, that other charges will be dismissed, or that sentence concessions will be granted, upon request of the parties the trial judge may permit the disclosure to him of the agreement and the reasons therefor in advance of the time for tender of the plea. He may then indicate whether he will concur in the proposed disposition. If, after the judge has indicated his concurrence with a plea agreement and the defendant has entered a plea of guilty or nolo contendere, but before sentencing, the judge decides that the disposition should not include the charge or sentence concessions contemplated by the agreement, he shall so advise the parties and then in open court call upon the defendant to either affirm or withdraw his plea.(c) If the parties have not sought the concurrence of the trial judge in a plea agreement or if the judge has declined to indicate whether he will concur in the agreement, he shall advise the defendant in open court at the time the agreement is stated that: (i) the agreement is not binding on the court; and(ii) if the defendant pleads guilty or nolo contendere the disposition may be different from that contemplated by the agreement.(d) A verbatim record of all proceedings had in open court pursuant to subsections (b) and (c) of this rule shall be made and preserved by the court.
