The appellant filed this action against the appellees, Georgia Hi-Lift Corporation and Steve Fowler, to recover for injuries he had allegedly sustained when a MARTA bus he was driving was struck by a tractor-trailer owned by Georgia Hi-Lift and being driven by Fowler. Previously, the appellant, the appellees, and MARTA had all been named as co-defendants in separate suits filed by two bus passengers to recover for injuries they had sustained in the accident. The appel*454lant and MARTA, who were represented in those actions by the same counsel, filed cross-claims against the appellees seeking indemnification and contribution for any recovery the passengers might obtain against them. That litigation was subsequently settled, resulting in the voluntary dismissal with prejudice of all the claims asserted therein, including the appellant’s cross-claims against the appellees for indemnification and contribution. Based on those dismissals, the trial court granted summary judgment to the appellees in the present action on the theory that the appellant’s claims were barred by the doctrine of res judicata, as set forth in OCGA § 9-12-40. This appeal followed. Held:
OCGA § 9-12-40 provides as follows: “A judgment of a court of competent jurisdiction shall be conclusive between the same parties and their privies as to all matters put in issue or which under the rules of law might have been put in issue in the cause wherein the judgment was rendered until the judgment is reversed or set aside.”
It has been held that a voluntary.dismissal with prejudice, involving no judicial action, does not constitute a “judgment of a court” so as to have res judicata effect pursuant to this Code section. See Market Ins. Corp. v. IHM, Inc., 192 Ga. App. 441, 442 (2) (385 SE2d 307) (1989). See also World Mut. &c. Ins. Co. v. Thurmond, 112 Ga. App. 393 (1) (145 SE2d 252) (1965). Moreover, it is well established that, in order for a prior judgment to . have res judicata effect in subsequent litigation between the same parties, the prior action must have involved the same cause of action. See Winters v. Pund, 179 Ga. App. 349, 352 (346 SE2d 124) (1986); Lewis v. Price, 104 Ga. App. 473 (1), 474-5 (122 SE2d 129) (1961).
The cross-claims for indemnification and contribution previously filed against the appellees by the appellant clearly did not involve the same cause of action as is being asserted by the appellant in the present case, for the appellant did not seek in the earlier litigation to recover for his own injuries sustained as a result of the collision. While the appellant certainly could have asserted the present cause of action by cross-claim in either of the suits filed by the bus passengers, his disinclination to do so is quite understandable, for he was being defended by MARTA’s counsel in those actions and to have sought recovery against the appellees for his own injuries in the context of those proceedings would undoubtedly have complicated the task of presenting the claim to a jury, perhaps diminishing his chances for recovery. We do not believe the law required him to pursue his personal injury claim in this manner.
Based on the language of OCGA § 9-11-13 (g), it has been held that “[a] cross claim is not compulsory, but is permissive.” Reeves Transp. Co. v. Gamble, 126 Ga. App. 165, 167 (190 SE2d 98) (1972). We believe that rule continues to be viable, although we recognize *455that the Supreme Court’s decision in Citizens Exchange Bank of Pearson v. Kirkland, 256 Ga. 71, 72 (344 SE2d 409) (1986), could, perhaps, be interpreted as having altered it. 'J’hat case involved a suit by an executrix against a bank to recover for the loss of a certificate of deposit which had been paid to the decedent’s widow rather than to the estate. The widow had previously sued both the executrix and the bank seeking a judicial declaration that she was entitled to the funds, and a default judgment to that effect had been entered in the action based on the executrix’s failure to answer and on the bank’s representation to the court that it was a “neutral party.” The Supreme Court held that this judgment constituted a bar to the executrix’s subsequent suit against the bank, using language which implied that her claim against the bank should have been raised as a cross-claim in the declaratory judgment action. However, the executrix’s claim against the bank clearly was predicated on a contention that the estate rather than the widow had been legally entitled to the proceeds of the CD, and it was precisely this point which had been resolved adversely to the estate in the declaratory judgment proceeding. Thus, the executrix’s claim against the bank was, in actuality, barred not so much by her failure to file a cross-claim in the prior action as by her failure to file an answer in that action.
“[I]n modern legal practice, the central issue in determining whether the doctrines of res judicata and collateral estoppel apply is whether the party against whom the plea is raised has had full opportunity to litigate the issues. [Cits.]” Winters v. Pund, supra at 352. Cf. OCGA § 9-12-42; Delta Air Lines v. Woods, 137 Ga. App. 693, 695 (224 SE2d 763) (1976); A. R. Hudson Realty v. Hood, 151 Ga. App. 778, 779 (262 SE2d 189) (1979). As the appellant has not previously sought to recover from the appellees for the personal injuries which he allegedly sustained in the accident, and as we do not believe he forfeited his right to do so by failing to assert this cause of action as a cross-claim in either of the personal injury suits filed by the bus passengers, we hold that the trial court erred in granting summary judgment to the appellees on res judicata grounds.
Judgment reversed.
