Navigating the Murky Waters of Market Share Liability: Understanding Sindell v. Abbott Laboratories (1980)
Imagine suffering a severe injury from a product, but being unable to pinpoint which manufacturer was responsible. This is the dilemma that led to the development of market share liability, a legal doctrine that deviates from traditional tort principles. Sindell v. Abbott Laboratories, a landmark 1980 California Supreme Court case, established this concept, forever changing the landscape of product liability law, particularly in cases involving the drug diethylstilbestrol (DES).
The DES Tragedy: A Perfect Storm for Market Share Liability
In the mid-20th century, DES was prescribed to pregnant women to prevent miscarriages. Tragically, it was later discovered that DES exposure in utero led to various health problems in their daughters, including a rare form of vaginal cancer. These women, now adults, faced an impossible hurdle: identifying which of the many DES manufacturers produced the specific pills their mothers had ingested decades prior. This inability to identify the specific tortfeasor threatened to leave countless victims without recourse.
Sindell v. Abbott Laboratories: A New Legal Avenue
The California Supreme Court in Sindell v. Abbott Laboratories recognized the injustice of this situation. Traditional product liability law requires a plaintiff to prove that a specific defendant’s product caused their injury. However, the court acknowledged that this requirement was insurmountable in many DES cases due to the passage of time and the generic nature of the drug.
To address this, the court created the doctrine of market share liability. This groundbreaking theory allows a plaintiff to sue multiple DES manufacturers, even without knowing which one produced the specific DES their mother took. Each manufacturer’s liability is then proportional to its share of the DES market at the time the drug was ingested.
Key Elements of Market Share Liability
Sindell established several key requirements for applying market share liability:
- Substantial Share of the Market: The plaintiff must sue manufacturers representing a substantial share of the relevant DES market. This ensures that the majority of potential wrongdoers are present in court.
- Fungible Product: The product in question must be fungible, meaning it is essentially identical regardless of the manufacturer. In Sindell, the court emphasized that all DES had the same chemical composition.
- Defendants in the Market: All potential tortfeasors must have been in the market during the period when the injury occurred.
- Inability to Identify the Tortfeasor: The plaintiff’s inability to identify the specific manufacturer must not be their fault.
How Market Share Liability Works
Once these elements are met, the burden of proof shifts to the defendant manufacturers. Each defendant is liable for a percentage of the plaintiff’s damages that corresponds to its market share.
For example, if a plaintiff wins a \$1 million judgment and a defendant had 20% of the DES market, that defendant would be responsible for \$200,000 in damages.
Jurisdictional Acceptance and Variations
While Sindell originated in California, other states have adopted or rejected market share liability, or have created their own versions. New York, for example, adopted market share liability in Hymowitz v. Eli Lilly & Co. (1989), but with a significant modification: defendants could not exculpate themselves by proving they did not manufacture the specific DES in question. The New York court reasoned that allowing exculpation would undermine the purpose of market share liability.
Wisconsin adopted a “risk-contribution theory,” similar to market share liability, focusing on whether each defendant contributed to the injury, their ability to absorb costs, and whether damages would incentivize loss reduction.
However, many states still refuse to adopt market share liability, even in DES cases, possibly due to the mass litigation it has created in states that have adopted it.
Criticisms and Limitations
Market share liability is not without its critics. Some argue that it deviates too far from traditional tort principles by holding manufacturers liable even without proof of direct causation. Concerns have also been raised about the difficulty of accurately determining market share, especially decades after the fact.
Furthermore, attempts to extend market share liability beyond DES cases have generally failed. Courts have been reluctant to apply the doctrine to other products, often citing differences in fungibility or the difficulty of defining the relevant market. For example, cases involving asbestos and lead paint have generally been unsuccessful in applying market share liability.
The Enduring Legacy of Sindell
Despite its limitations and criticisms, Sindell v. Abbott Laboratories remains a landmark case. It provided a remedy for victims who would have otherwise been left without recourse and sparked a national debate about the balance between compensating injured parties and adhering to traditional tort principles.
The case serves as a reminder that the law must adapt to address new challenges and ensure fairness in the face of evolving circumstances. While market share liability may not be a perfect solution, it represents a significant step towards achieving justice for those injured by products when specific identification of the manufacturer is impossible.
