(A) The trial judge should not participate in plea discussions. (B) If a tentative plea agreement has been reached, upon request of the parties, the trial judge may permit the parties to disclose the tentative agreement and the reasons therefor in advance of the time for the tendering of the plea. The judge may then indicate to the prosecuting attorney and defense counsel whether the judge will likely concur in the proposed disposition if the information developed in the plea hearing or presented in the presentence report is consistent with the representations made by the parties. If the trial judge concurs but the final disposition differs from that contemplated by the plea agreement, then the judge shall state for the record what information in the presentence report or hearing contributed to the decision not to sentence in accordance with the plea agreement. (C) When a plea of guilt or nolo contendere is tendered or received as a result of a plea agreement, the trial judge should give the agreement due consideration, but notwithstanding its existence, must reach an independent decision on whether to grant charge or sentence leniency under the principles set forth in section 33.6 of these rules.
