Opinion
Aрpellant Marion Faye Vahey brought an action for personal injuries against respondent Sandra Sacia and others involved in a five-car collision. The matter was settled and dismissed as to the other defendants. A jury returned a general verdict, finding in favor of respondеnt. A motion for new trial was denied. The appeal is from the judgment.
A car driven by A stopped on the highway and was hit by a car driven by B. C ran into B. There was evidence from which it could be concluded that appellant’s car (the fourth car), driven by her husband, hit C’s car and then was hit by respоndent Sacia’s (the fifth car). It could be concluded from other evidence that Mr. Vahey stopped and then respondent ran into him and pushed him into C. Appellant suffered a severe hip injury, either in the collision with C or in the collision with respondent. There was evidence thаt she would not have suffered the particular injury if she had been wearing a seat belt.
*174 There was no question but that A, B and/or C were negligent, and such negligence was either the cause or a contributing cause of appellant’s injury. It also appears that there was no substаntial question of Mr. Vahey’s negligence.
1. Instruction on Burden of Proof
Appellant requested the instruction set forth in the margin,

which quoted headnote 4 to
Cummings
v.
Kendall
(1940)
Appellant contends on appeal that the refusal of the instructions was prejudicial error. She relies on the cases cited above and in the Use Note, as well as
Summers
v.
Tice
(1948)
Summers,
the leading case, is summarized by 4 Witkin, Summary of California Law (8th ed. 1974) section 625, page 2907, as follows: “A significant doctrine, phrased in terms of burden of proof but having a clear substantive effect, was announced in
Summers
v.
Tice
(1948) 33 C.2d 80,
Summers
does not cite the earlier
Cummings
decision. The facts were that A ran into B, and a split second later, C hit B, injuring B’s passenger. The court held that the C defendants, “wrongdoers, carry the burden of showing that no injuries resulted from their wrong and their task is to unravel the casuistries. In arguing the impossibility of doing this they concede their failure.” (
Copley,
which follows
Summers
and
Cummings,
is virtually identical to
Cummings
on its facts. It held that it was error to instruct that the burden was on B to show that C caused B’s injuries and that C was liable only for such injuries as he was shown to have caused. The court gave tacit approval to an instruction thаt “‘if you find that the accident complained of was proximately caused by concurrent negligence on the part of the defendants [A & C], .. . then . . . neither defendant can escape liability by claiming that all the injuries were inflicted by the impact with the car of the other defendant, unless such defendant proves by a preponderance of the evidence that no injuries resulted from his negligence.’” (
In
Apodaca
v.
Haworth
(1962)
A more recent case applies the
Summers
principle and presents a factual situation schematically similar to the present casе.
(Lareau
v.
Southern Pac. Transportation Co.
(1975)
In the present case, the court rejected the proposed instruсtion, at least in part, because of a belief that the law had been changed by
Li
v.
Yellow Cab Co.
(1975)
Sindell
v.
Abbott Laboratories
(1980)
Respondent argues that appellant’s proposed instructions wеre correctly rejected for five reasons: (a) the Summers principle applies only where there are two defendants and here there was only one, (b) Summers applies where there is an innocent plaintiff and here the plaintiff *177 may have caused her own injuries by fаiling to wear a seat belt, (c) the reason for the Summers rule is obviated by the doctrine of comparative negligence, (d) the reason for the rule does not apply to this case, in any event, because the plaintiff was in a better position than respondent to know who caused her injury, and (e) the instructions, as phrased by appellant, were argumentative and confusing. These arguments are discussed in turn.
(a)
Summers applies to multiple tortfeasors 2 not to multiple defendants, and it is immaterial in this case that the matter went to trial only as against respondent, for A, B, and/or C was also a tortfeasor.
(b)
If Summers applies оnly to an innocent plaintiff, nevertheless the jury should be instructed in accordance with it, in case they find that the plaintiff was innocent.
(c)
More important, there is no good reason why the law of comparative negligence should affect the reasoning that led to the rule of Summers. It is true that in Summers, presumably the plaintiff was not negligent. But, of course, when Summers was decided, contributory negligence was a complete defense. Thus, only an innocent plaintiff could utilize the Summers principle. But, with the advent of comparative negligence, if, for example, in the facts of Summers, the injured hunter had been one-third responsible for his injuries because of his negligence, the rationale of Summers should be equally applicable and require that each of his fellow hunters have the burden of proving that he was not negligent or that his negligence was not two-thirds, thе proximate cause of the injury.
(d)
The question is not simply, or only, who is in a better position to prove whose act caused the injury. Instead, in this case, as in
Haft
v.
*178
Lone Palm Hotel
(1970)
(e)
The instruction which appellant first requested (see fn. 1 above) was to a degree, as respondent argues, argumеntative and confusing. (3) It has been held that “A trial court has no duty to modify or edit an instruction offered by either side in a civil case” and “[i]f the instruction is incomplete or erroneous the trial judge may ... properly refuse it.”
(Truman
v.
Thomas
(1980)
It is possible that the jury’s verdict was based on a failure on appellant’s part tо prove respondent’s negligence. It is also possible that the jury found respondent to be negligent but returned a verdict in favor of respondent because of the failure of appellant to prove that such negligence was the cause of her injury. A rational viеw of the evidence is that appellant was injured by the negligence of A, B, and/or C and/or the negligence of respondent, Under the circumstances, it was difficult for .appellant to “pin the injury on one of the defendants only”
(Summers
v.
Tice, supra,
2. Misconduct of Counsel
We have reviewed the contentions of misconduct of counsel and find them to be without merit.
3. Instruction as to Deduction of Settlement with Joint Tortfeasor
Appellant also contends that she should have been allowed to introduce evidence of the settlement and the jury should have beеn instructed in accordance with BAJI No. 14.63—or, if no such evidence were admitted, the jury should have been instructed according to BAJI No. 14.64.
It would seem that the appropriate procedure would have been to accept an admission of the amount of settlemеnt and then to give the latter instruction.
(Albrecht
v.
Broughton
(1970)
*180 The error in refusing to instruct was harmless, however, because it went only to damages, and, as noted above, the jury found respondent not to be negligent or her negligence not to be the cause of the injury. Thus it never reached the issue of dаmages.
The judgment is reversed.
White, P. J., and Barry-Deal, J., concurred.
A petition for a rehearing was denied December 18, 1981.
Notes
‘‘Where the automobile in which a person was a passenger collided with another car and was then struck by a third, the driver of the latter whose negligence concurred with that of the second cannot escape liability on the claim that all of the injuries wеre inflicted at the first impact where he is unable to prove that no injuries resulted from his wrong.”
Or perhaps, more precisely, where there are multiple causes, at least one tortious. (See
