BENHAM, Chief Justice.
This appeal arises from an action for personal injuries suffered by Parrish when she was assaulted by two prisoners who had escaped from a work detail being supervised by Jones. Two of the defendants, Jones and his supervisor, were granted summary judgment on the ground of official immunity.[1] The Court of Appeals affirmed that judgment (Parrish v. Akins, 233 Ga.App. 442, 504 S.E.2d 276 (1998)), and this Court granted the writ of certiorari to consider the apparent conflict between the decisions of the Court of Appeals in this case and in Bontwell v. Dept. of Corrections, 226 Ga.App. 524, 486 S.E.2d 917 (1997), and its decision in Simmons v. Coweta County, 229 Ga.App. 550(c), 494 S.E.2d 362 (1997), reversed in part on other grounds in Coweta County v. Simmons, 269 Ga. 694, 507 S.E.2d 440 (1998).[2]
The posture of the defendants in the cases is identical: each is a person responsible for supervision of a prisoner work detail who is accused of negligence in the performance of that duty. The holdings of the Court of Appeals in this case and in Bontwell are, however, diametrically opposed to its holding in Simmons. There, the Court of Appeals held that "[d]irecting, supervising, and guarding a routine detail of correctional inmates in picking up trash and cutting grass along a county road involves no discretion and was ministerial in nature as a matter of law." Simmons, supra at 554, 494 S.E.2d 362. By contrast, the Court of Appeals held in Bontwell that "the ... supervision of convicts on work details outside the boundaries of [a] correctional institute ... is a discretionary governmental function ... as opposed to a ministerial, proprietary, or administratively routine function." Id. at 527, 486 S.E.2d 917. In its opinion in the present case, the Court of Appeals cited Bontwell and held that under the circumstances of this case "the task given to Officer Jones to supervise inmates working outside [the prison] was a discretionary, as opposed to a ministerial, function." Parrish, supra at 444, 504 S.E.2d 276.
The reasoning of the Court of Appeals in Parrish is persuasive, pointing out that the guard had to exercise discretion in deciding on the makeup of the detail, in determining how to supervise the inmates, and in balancing the responsibilities imposed by regulation "for maintaining custody, assuring discipline, achieving productivity, the care, control and maintenance of equipment, and the safety of both inmates and the general public." Id. at 443, 504 S.E.2d 276.
The opinion in Simmons, on the other hand, does not contain any reasoning to support the conclusion that the officer's duties were ministerial as a matter of law. Moreover, the very verbs used in Simmons to describe the guard's duties, "[d]irecting, supervising, and guarding ...," fit very well in the reasoning employed by the Court of Appeals in the present case: In the context of a prisoner work detail, those duties contain inherent conflicts between the need to get work done and the need to maintain security. In Simmons, as in the present case and in Bontwell, the guard was required to exercise judgment in choosing the priority to be assigned to those diverse responsibilities.
*836 We also note that the positions taken by the Court of Appeals in this case and in Bontwell are well supported by authority. See Merrow v. Hawkins, 266 Ga. 390(1), 467 S.E.2d 336 (1996); McDay v. City of Atlanta, 204 Ga.App. 621(2), 420 S.E.2d 75 (1992); Vertner v. Gerber, 198 Ga.App. 645, 402 S.E.2d 315 (1991); Price v. Owen, 67 Ga.App. 58, 19 S.E.2d 529 (1942). The holding in Simmons, by contrast, though accompanied by citation of statutes and cases, is without direct support in the authority cited therein or elsewhere.
We conclude from our consideration of the Court of Appeals's opinions in this case, in Bontwell, and in Simmons, that the correct holding in these three indistinguishable cases is the holding in this case and in Bontwell that the supervision of a prisoner work detail is a discretionary function by virtue of which the supervisor is entitled to official immunity. Consequently, the judgment of the Court of Appeals in the present case is affirmed and its holding in Simmons is overruled.
Judgment affirmed.
All the Justices concur.
