Question 1: Was it fair to allow suit against companies based on their "market share" involvement in the production and sale of DES (market-share liability)?
Question 2: If not, should anyone be held accountable for the injury caused to DES-daughters?
Question 3: Is it fair to sue only those companies that captured the majority market share?
Question 4: Would it be fair to sue all of the companies who sold DES during this period (enterprise liability)?
Question 5: Is it fair to sue a company with a share of the market, even if the company can prove its product could not possibly have been the one Jane Sindell's mother took?
Case Scenario:
SINDELL v. ABBOTT LABORATORIES
California Supreme Court 26 Cal. 3d 588 (1980)
Generally, a plaintiff has the burden of proving that her harm was caused by the defendant. What happens when the exposure took place long ago and the toxic substance may have been manufactured by any of a number of companies? The Sindell decision addressed this not uncommon problem.
MOSK, J. This case involves a complex problem both timely and significant; may a plaintiff, injured as the result of a drug administered to her mother during pregnancy, who knows the type of drug involved but cannot identify the manufacturer of the precise product, hold liable for her injuries a maker of a drug produced from an identical formula?
Plaintiff Judith Sindell brought an action against eleven drug companies and Does 1 through 100, on behalf of herself and other women similarly situated. The complaint alleges as follows:
Between 1941 and 1971, defendants were engaged in the business of manufacturing, promoting, and marketing diethylstilbesterol (DES), a drug which is a synthetic compound of the female hormone estrogen. The drug was administered to plaintiff's mother and the mothers of the class she represents (see note 1), for the purpose of preventing miscarriage. In 1947, the Food and Drug Administration authorized the marketing of DES as a miscarriage preventative, but only on an experimental basis, with a requirement that the drug contain a warning label to that effect.
DES may cause cancerous vaginal and cervical growths in the daughters exposed to it before birth, because their mothers took the drug during pregnancy. The form of cancer from which these daughters suffer is known as adenocarcinoma, and it manifests itself after a minimum latent period of 10 or 12 years. It is a fast-spreading and deadly disease, and radical surgery is required to prevent it from spreading. DES also causes adenosis, precancerous vaginal and cervical growths which may spread to other areas of the body. The treatment for adenosis is cauterization, surgery, or cryosurgery. Women who suffer from this condition must be monitored by biopsy or colposcopic examination twice a year, a painful and expensive procedure. Thousands of women whose mothers received DES during pregnancy are unaware of the effects of the drug....
Defendants demurred (see note 2) to the complaint. While the complaint did not expressly allege that plaintiff could not identify the manufacturer of the precise drug ingested by her mother, she stated … that she was unable to make the identification, and the trial court sustained the demurrers of these defendants without leave to amend on the ground that plaintiff did not and stated she could not identify which defendant had manufactured the drug responsible for her injuries. Thereupon, the court dismissed the action. This appeal involves only five of ten defendants named in the complaint....
This case is but one of a number filed throughout the country seeking to hold drug manufacturers liable for injuries allegedly resulting from DES prescribed to the plaintiffs' mothers since 1947. According to a note in the Fordham Law Review, estimates of the number of women who took the drug during pregnancy range from 1 million to 3 million. Hundreds, perhaps thousands, of the daughters of these women suffer from adenocarcinoma, and the incidence of vaginal adenosis among them is 30 to 90 percent. (Comment, DES and a Proposed Theory of Enterprise Liability (1978) 46 Fordham L. Rev. 963, 964-967 [hereafter Fordham Comment].) Most of the cases are still pending. With two exceptions, those that have been decided resulted in judgments in favor of the drug company defendants because of the failure of the plaintiffs to identify the manufacturer of the DES prescribed to their mothers. The same result was reached in a recent California case. (McCreery v. Eli Lilly & Co. (1978) 87 Cal. App. 3d 77, 82-84, 150 Cal. Rptr. 730.) The present action is another attempt to overcome this obstacle to recovery.
We begin with the proposition that, as a general rule, the imposition of liability depends upon a showing by the plaintiff that his or her injuries were caused by the act of the defendant or by an instrumentality under the defendant's control....
There are, however, exceptions to this rule. Plaintiff's complaint suggests several bases upon which defendants may be held liable for her injuries even though she cannot demonstrate the name of the manufacturer which produced the DES actually taken by her mother. The first of these theories, classically illustrated by Summers v. Tice (1948) 33 Cal. 2d 80, 199 P.2d 1, places the burden of proof of causation upon tortious defendants in certain circumstances. The second basis of liability emerging from the complaint is that defendants acted in concert to cause injury to plaintiff. There is a third and novel approach to the problem, sometimes called the theory of "enterprise liability,'' but which we prefer to designate by the more accurate term of "industry-wide'' liability, which might obviate the necessity for identifying the manufacturer of the injury-causing drug. We shall conclude that these doctrines, as previously interpreted, may not be applied to hold defendants liable under the allegations of this complaint. However, we shall propose and adopt a fourth basis for permitting the action to be tried, grounded upon an extension of the Summers doctrine.
Plaintiff places primary reliance upon cases which hold that if a party cannot identify which of two or more defendants caused an injury, the burden of proof may shift to the defendants to show that they were not responsible for the harm. This principle is sometimes referred to as the "alternative liability'' theory.
The celebrated case of Summers v. Tice, supra, 33 Cal. 2d 80, 199 P.2d 1, a unanimous opinion of this court, best exemplifies the rule. In Summers, the plaintiff was injured when two hunters negligently shot in his direction. It could not be determined which of them had fired the shot which actually caused the injury to the plaintiff's eye, but both defendants were nevertheless held jointly and severally liable for the whole of the damages. We reasoned that both were wrongdoers, both were negligent toward the plaintiff, and that it would be unfair to require plaintiff to isolate the defendant responsible, because if the one pointed out were to escape liability, the other might also, and the plaintiff-victim would be shorn of any remedy. In these circumstances, we held, the burden of proof shifted to the defendants, "each to absolve himself if he can.'' ...
In Summers, we relied upon Ybarra v. Spangard (1944) 25 Cal. 2d 486, 154 P.2d 687. There, the plaintiff was injured while he was unconscious during the course of surgery. He sought damages against several doctors and a nurse who attended him while he was unconscious. We held that it would be unreasonable to require him to identify the particular defendant who had performed the alleged negligent act because he was unconscious at the time of the injury and the defendants exercised control over the instrumentalities which caused the harm. Therefore, under the doctrine of res ipsa loquitur, an inference of negligence arose that defendants were required to meet by explaining their conduct....

Here, as in Summers, the circumstances of the injury appear to render identification of the manufacturer of the drug ingested by plaintiff's mother impossible by either plaintiff or defendants, and it cannot reasonably be said that one is in a better position than the other to make the identification. Because many years elapsed between the time the drug was taken and the manifestation of plaintiff's injuries she, and many other daughters of mothers who took DES, are unable to make such identification. Certainly there can be no implication that plaintiff is at fault in failing to do so--the event occurred while plaintiff was in utero, a generation ago.
On the other hand, it cannot be said with assurance that defendants have the means to make the identification. In this connection, they point out that drug manufacturers ordinarily have no direct contact with the patients who take a drug prescribed by their doctors. Defendants sell to wholesalers, who in turn supply the product to physicians and pharmacies. Manufacturers do not maintain records of the persons who take the drugs they produce, and the selection of the medication is made by the physician rather than the manufacturer. * * *
It is important to observe, however, that while defendants do not have means superior to plaintiff to identify the maker of the precise drug taken by her mother, they may in some instances be able to prove that they did not manufacture the injury-causing substance. In the present case, for example, one of the original defendants was dismissed from the action upon proof that it did not manufacture DES until after plaintiff was born.... Nevertheless, plaintiff may not prevail in her claim that the Summers rationale should be employed to fix the whole liability for her injuries upon defendants, at least as those principles have previously been applied. There is an important difference between the situation involved in Summers and the present case. There, all the parties who were or could have been responsible for the harm to the plaintiff were joined as defendants. Here, by contrast, there are approximately 200 drug companies which made DES, any of which might have manufactured the injury-producing drug.
Defendants maintain that, while in Summers there was a 50 percent chance that one of the two defendants was responsible for the plaintiff's injuries, here since any one of 200 companies which manufactured DES might have made the product which harmed plaintiff, there is no rational basis upon which to infer that any defendant in this action caused plaintiff's injuries, nor even a reasonable possibility that they were responsible.
[Therefore] we approach the issue of causation from a different perspective: we hold it to be reasonable in the present context to measure the likelihood that any of the defendants supplied the product which allegedly injured plaintiff by the percentage which the DES sold by each of them for the purpose of preventing miscarriage bears to the entire production of the drug sold by all for that purpose. Plaintiff asserts in her briefs that Eli Lilly and Company and 5 or 6 other companies produced 90 percent of the DES marketed. If at trial this is established to be the fact, then there is a corresponding likelihood that this comparative handful of producers manufactured the DES which caused plaintiff's injuries, and only a 10 percent likelihood that the offending producer would escape liability.
If plaintiff joins in the action the manufacturers of a substantial share of the DES which her mother might have taken, the injustice of shifting the burden of proof to defendants to demonstrate that they could not have made the substance which injured plaintiff is significantly diminished. While 75 to 80 percent of the market is suggested as the requirement ..., we hold only that a substantial percentage is required.
The presence in the action of a substantial share of the appropriate market also provides a ready means to apportion damages among the defendants. Each defendant will be held liable for the proportion of the judgment represented by its share of that market unless it demonstrates that it could not have made the product which caused plaintiff's injuries. In the present case, as we have seen, one DES manufacturer was dismissed from the action upon filing a declaration that it had not manufactured DES until after plaintiff was born. Once plaintiff has met her burden of joining the required defendants, they in turn may cross-complaint against other DES manufacturers, not joined in the action, which they can allege might have supplied the injury-causing product.
Under this approach, each manufacturer's liability would approximate its responsibility for the injuries caused by its own products. Some minor discrepancy in the correlation between market share and liability is inevitable; therefore, a defendant may be held liable for a somewhat different percentage of the damage than its share of the appropriate market would justify. It is probably, impossible, with the passage of time, to determine market share with mathematical exactitude. But just as a jury cannot be expected to determine the precise relationship between fault and liability in applying the doctrine of comparative fault (Li v.Yellow Cab Co. (1975) 13 Cal. 3d 804, 119 Cal. Rptr. 858, 532 P.2d 1226) or partial indemnity (American Motorcycle Assn. v. Superior Court (1978) 20 Cal. 3d 578, 146 Cal. Rptr. 182, 578 P.2d 899), the difficulty of apportioning damages among the defendant producers in exact relation to their market share does not seriously militate against the rule we adopt. As we said in Summers with regard to the liability of independent tortfeasors, where a correct division of liability cannot be made "the trier of fact may make it the best it can.'' (33 Cal. 2d at p.88, 199 P.2d at p.5.)
We are not unmindful of the practical problems involved in defining the market and determining market share, but these are largely matters of proof which properly cannot be determined at the pleading stage of these proceedings. Defendants urge that it would be both unfair and contrary to public policy to hold them liable for plaintiff's injuries in the absence of proof that one of them supplied the drug responsible for the damage. Most of their arguments, however, are based upon the assumption that one manufacturer would be held responsible for the products of another or for those of all other manufacturers if plaintiff ultimately prevails. But under the rule we adopt, each manufacturer's liability for an injury would be approximately equivalent to the damages caused by the DES it manufactured.
