The STATE
v.
EVANS.
No. S07A0033.
Supreme Court of Georgia.
June 4, 2007.
*78 Paul L. Howard Jr., Dist. Atty., Marc A. Mallon, Bettieanne C. Hart, Asst. Dist. Attys.; Thurbert E. Baker, Atty. Gen., Department of Law, Atlanta, for Appellant.
Averick Walker, Walker Law Office, Atlanta, for Appellee.
HINES, Justice.
The State seeks to appeal the trial court's judgment acquitting Jason Evans on charges of malice murder, felony murder, and aggravated assault. Finding that the State cannot appeal such a judgment and that this Court is therefore without jurisdiction to address this matter, we dismiss the appeal.
Evans, together with Sovensky Maddox, was indicted for malice murder, felony murder, and two counts of aggravated assault, in connection with the death of LaFayette Smith. Evans moved to sever his trial from that of Maddox, and, before jury selection began, argued in the alternative that the trial court conduct a bench trial for him simultaneously with Maddox's jury trial. The court did so over the State's objection. Following the trial, the court pronounced Evans not guilty on all counts, and entered an appropriate order of acquittal. The State filed a notice of appeal.
The circumstances of the appeal require that this Court inquire into its jurisdiction. See Collins v. State, 277 Ga. 586, 591 S.E.2d 820 (2004). "In OCGA § 5-7-1(a), the General Assembly has set forth only a limited right of appeal for the State in criminal cases. [Cits.]" Howard v. Lane, 276 Ga. 688, 581 S.E.2d 1 (2003). If the State attempts an appeal outside the ambit of OCGA § 5-7-1(a), the appellate courts do not have jurisdiction to entertain it. Id. OCGA § 5-7-1(a) does not purport to authorize the State to appeal a judgment of acquittal, nor is a trial court's decision to proceed with a bench trial over the State's objection one of the statutorily-enumerated rulings that the State can appeal.[1] In fact, in Howard, id., the State wished to prevent a bench trial in lieu of a jury trial, and this Court specifically noted that, under OCGA § 5-7-1(a), the State has "no right" to directly appeal the trial court's ruling that a bench trial would occur. Id. at 689, 581 S.E.2d 1. While OCGA § 5-7-1(a) has been amended since this Court's decision in Howard, the General Assembly did not include any provision that would embrace this situation.
Nonetheless, the State asserts that the trial court's order is appealable under OCGA § 5-7-1(a)(5), which empowers the State to take an appeal from a judgment "where the court does not have jurisdiction or the order is otherwise void under the Constitution or laws of this state." The State contends that the acquittal is void, likening a bench trial over its objection to a jury trial in which the *79 jurors were not sworn, in which instance, the proceeding is a nullity. See Spencer v. State, 281 Ga. 533, 640 S.E.2d 267 (2007); Slaughter v. State, 100 Ga. 323, 28 S.E. 159 (1897). But, here there is no question of the trial court's oath of office and concomitant authority, only the proper exercise of that authority.
In a prior case, this Court has determined that a trial court cannot conduct a criminal bench trial over the State's objection. See Zigan v. State, 281 Ga. 415, 638 S.E.2d 322 (2006). However, that decision does not create a right of appeal for the State; creation of any such right is a function for the General Assembly, not this Court.
Nor is it the case that any improper exercise of a trial court's authority renders a judgment void. In the specific situation of an adjudication on the question of guilt in a criminal bench trial when a bench trial is erroneously conducted over the State's objection, the result of such bench trial is an ineffective waiver of the right to a trial by jury, not a void judgment. See Zigan, supra at 416-417, 638 S.E.2d 322. Rather, the judgment following an ineffective waiver may be reviewed on its merits on appeal, if one is available. See, e.g., Balbosa v. State, 275 Ga. 574, 571 S.E.2d 368 (2002). But, the question of whether an appeal is available to the State from the decision of a trial court to proceed with a bench trial over the State's objection has been decided by the General Assembly, and it has decided that the answer is "no."
The decision below does not implicate the trial court's subject matter jurisdiction, or its jurisdiction over the person of the defendant. See Collins, supra. The judgment was entered by a court of competent jurisdiction. See State v. Glover, 281 Ga. 633, 641 S.E.2d 543 (2007). It is not void, no appeal was available to the State, and consequently this appeal must be dismissed.
Appeal dismissed.
All the Justices concur.
