Terrance Olander Brown appeals from the denial of his motion to set aside a guilty plea.[1] Finding no error, we affirm.
Brown and others were charged in a multi-count indictment with offenses stemming from a sale of marijuana during which one person was shot to death, another was wounded, and money was taken from the victims at gunpoint. Brown's attorney entered into plea negotiations with the prosecution. After learning that all co-defendants had pled guilty, waived their rights to appeal, and agreed to testify against him, Brown reached a negotiated plea agreement with the State, which was reduced to writing. That document and the court's form agreement pursuant to Uniform Superior Court Rule 33.8 were signed by both Brown and his counsel and were made part of the plea record. Thereafter, Brown pled guilty to malice murder, aggravated assault (two counts), felony murder, and armed robbery. He was sentenced to two consecutive life sentences for malice murder and armed robbery of the murder victim, plus a concurrent sentence of twenty years for aggravated assault on the second victim.
After sentence was pronounced, but in the same term of court, Brown sent a letter to the judge suggesting that he wanted to withdraw his plea because "he received more time than the actual shooters and killer." The court treated this as a motion to withdraw the plea, appointed counsel, and entertained the request despite language in the State's Agreement that defendant waived the right to withdraw the plea and waived all other post-conviction relief. The court denied the motion, concluding that Brown knowingly, intelligently, and voluntarily entered his plea of guilty; that he understood the nature of the charges against him and the possible punishments for each charge; that there was an adequate factual basis for the plea; and that withdrawal of the guilty plea is not necessary to correct a manifest injustice.
1. Brown asserts that the plea agreement was not knowingly and intelligently made because it did not provide a correct statement of the crimes charged or the maximum possible punishments.
The trial court acknowledged inconsistencies in the two written plea agreements but stated that it was "fully satisfied based upon the totality of the circumstances ... that the defendant fully understood the maximum and minimum sentences for all the counts charged ... despite any scrivener's error to the contrary." Our review of the record of the plea hearing confirms this finding. *232 In response to the court's inquiry, Brown acknowledged that he understood the charges against him, that he discussed the plea agreement with his attorney and was aware of the rights he was waiving. This was confirmed by Brown's counsel. Thus, any ambiguities in the two plea agreements were clarified at the hearing. We conclude that the notification requirements of USCR 33.8(C)(2) were satisfied.
2. Contrary to Brown's assertions, the record at the plea hearing adequately establishes the existence of a factual basis for the plea. In this regard, the court heard from the prosecutor, defense counsel, and the defendant. Accordingly, there was full compliance with the mandatory requirements of USCR 33.9. See State v. Evans, 265 Ga. 332(1), 454 S.E.2d 468 (1995).
3. Brown further asserts that the State's Agreement was unenforceable and contrary to public policy because it deprived him of the right to challenge the validity of his guilty plea. The State agrees that a plea can always be challenged on grounds of voluntariness. See Allen v. Thomas, 265 Ga. 518, 458 S.E.2d 107 (1995) (right to challenge the knowing and voluntary nature of a guilty plea is not defeated by waiver of right to appeal). In the present case, the trial court considered Brown's challenge to his plea on all grounds asserted. Thus, he has not shown that he was harmed by any language in the State's Agreement.
Judgment affirmed.
All the Justices concur.
