Petitioners seek a writ of mandate to compel respondent court to enter an order granting their motion for a summary judgment. Petitioners contend that a prior judgment in their favor as defendants in a personal injury case brought by a husband and wife is a bar to a subsequent wrongful death action brought by the daughter of the deceased wife, and that the motion for summary judgment should have been granted on that ground.
The personal injury action was commenced hi 1961 by Bernard Moore and Sybil Moore, husband and wife, against these petitioners and others, as defendants, seeking damages based upon the alleged negligent medical treatment of Sybil Moore. A jury trial resulted in a verdict for the defendants, and judgment thereon became final in 1964.
On March 23, 1965, the wrongful death action was commenced by Bernard Moore and Linda Valerie Moore, a minor, husband and daughter of the deceased Sybil Moore, based upon the same alleged acts of negligence as those alleged in the personal injury action. The real party in interest herein *330 admits that the second complaint arose out of the same facts, but alleges that the wrongful death action seeks damages, not only for negligence, but for breach of contract arising from the Kaiser Permanente Plan.
Petitioners, defendants in the wrongful death action, moved for a summary judgment against both plaintiffs therein on the ground that the final judgment in the personal injury action was a bar. The respondent court, on January 26, 1967, entered its order granting the motion against plaintiff Bernard Moore on the ground that he was a party to the prior action and was collaterally estopped in this action. The motion was denied as to plaintiff Linda Valerie Moore, the real party in interest here, on the ground that since she was not a party to the prior action, she was not collaterally estopped by the prior judgment. Although the order in question was made on January 26, 1967, the petition before us was not filed until May 15, 1967. The real party in interest does not complain of this delay. She contends, however, that this is not a proper ease for the issuance of a writ of mandate. We agree. Petitioners here contend that they are entitled to a writ of mandate compelling the respondent court to grant their motion for a summary judgment. They contend in substance, that to force them to go to trial in the wrongful death action and then appeal from an adverse judgment does not constitute a plain, speedy and adequate remedy.
It has been held that: “A motion for summary judgment is a proper procedure by which to raise the defense of res judicata”
(Smith
v.
City of Los Angeles,
A motion for summary judgment is one of several procedures established by law whereby a party may secure a favorable determination of his plea of res judicata and thus avoid a trial of the case on the merits.
1
It must be remembered, however, that the function of a motion for summary judgment is limited and is to be distinguished from a motion for a trial of an affirmative defense under section 597 of the Code of Civil Procedure. (2 Witkin, Cal. Procedure (1954) Proceedings Without Trial, § 76(d), p. 1713.) “As to the procedure under section 437c, Code of Civil Procedure, the following is stated as a fundamental principle in
Eagle Oil & Ref. Co.
v.
Prentice,
Although it now appears from an examination of the record after oral argument that the alternative writ may have been inadvertently issued, nevertheless, having issued the alternative writ we assume for the purpose of this opinion only that mandamus is the proper remedy and that a determination on the merits of the issues raised by the petition will expedite rather than disturb the orderly processes of justice.
(Lockheed Aircraft Corp.
v.
Superior Court,
In the case before us the facts are undisputed. On the basis of those facts petitioners contend that the prior judgment against Sybil Moore in the personal injury action is conclusive against her daughter, Linda Valerie Moore, as plaintiff in the wrongful death action on the issue of liability as a matter of law “because (1) the prior judgment negatives the existence of conditions which would charge the petitioners with responsibility for Sybil’s death and (2) plaintiff is a privy or successor in interest of her mother and thus estopped from relitigating the issue of petitioners’ liability for Sybil’s injuries. ’ ’
‘ ‘ The doctrine of res judicata has a double aspect. As the court stated in
Todhunter
v.
Smith
(1934)
We are concerned here only with the second aspect of the doctrine, since there is a lack of identity of causes of action. “ The cause of action for wrongful death provided for in Code of Civil Procedure § 377 is an original one, arising on the death in favor of those designated by the statute as entitled to bring the action. It is not a cause of action derived from the decedent, by way of survival of a cause he may have had.” (55 Cal.Jur.2d, Wrongful Death, §10, p. 403.) Plaintiff was not a party to the personal injury action, nor was she. as contended by petitioners, in privity with or a successor to the interests of her mother. Her action is not derivative in character or a continuation or revival of the cause of action which her mother had before her death. It is a separate and distinct cause of action now existing in the plaintiff.
With regard to the application of the doctrine of judgment as collateral estoppel to strangers, the general rule is stated in 3 Witkin, California Procedure (1954) Judgment, section 69, pages 1958-1959: “Apart from special circumstances a stranger to an action, i.e., a person neither a party nor in privity, is not bound by the judgment. It is immaterial that he may have been vitally interested in and directly affected by the outcome of the action; due process requires that he have his own day in court. ’ ’
In
Bernhard
v.
Bank of America,
Plaintiff necessarily admits that the issues as to defendants’ negligence in her case are the same as those involved in the prior action in which there was a final judgment on the merits. The fact that she also seeks damages for
*335
breach of contract does not alter the case, since a breach of contract does not give rise to a cause of action for damages for wrongful death.
(Moxon
v.
County of Kern,
The alternative writ is discharged and the petition for a peremptory writ of mandate is denied.
Kaus, P. J., and Stephens, J., concurred.
Petitioners’ application for a hearing by the Supreme Court was denied November 8, 1967. Traynor, C. J., McComb, J., and Burke, J., were of the opinion that the petition should be granted.
Notes
Assigned by the Chairman of the Judicial Council.
Where, for example, a defendant affirmatively pleads res judicata as a bar to plaintiff’s claim, a decision in his favor on a motion under section 597, Code of Civil Procedure, for a separate trial of that defense before trial may render unnecessary the effort and expense of a trial on the merits. (2 Within, Cal. Procedure (1954) Trial, $ 3, pp. 1726-1727.) The defense may also be raised on a motion to dismiss.
(Stafford
v.
Yerge,
It has been held that the doctrine of res judicata as declared in
Bernhard,
despite the broad language used, does not apply to multiple negligence claims of several plaintiffs against a single defendant or group of defendants arising out of a single accident so that the determination of the negligence of such defendant or defendants in one action successfully brought by one plaintiff will perforce be res judicata in all subsequent actions brought by the remaining plaintiffs, upon the mere basis that the defendant or group of defendants were parties to the first action.
