Strict liability is an effective legal principle in California personal injury law that enables the injured to hold a party at fault without having to establish fault or negligence. Even though it takes away a key obstacle for plaintiffs, strict liability does not automatically apply. Plaintiffs still need to prove some fundamental legal requirements in order to win a strict liability claim.
This article summarizes the essentials of strict liability in California, particularly in the realm of product liability, animal attacks, and ultrahazardous acts. Familiarity with these essentials will enable injury victims and their lawyers to construct a strong claim and steer clear of frequent legal pitfalls.
What Is Strict Liability?
Strict liability is a legal principle that imposes responsibility for damages on a party regardless of intent, fault, or negligence. The law assumes that the activity, product, or situation is inherently dangerous or defective and that the party responsible should bear the costs if harm results.
Unlike negligence cases—which require proof that the defendant failed to act with reasonable care—strict liability cases center on the nature of the product or conduct that caused the injury.
When Is Strict Liability Applied?
In California, strict liability most often arises in the following types of cases:
- Defective products (product liability)
- Dog bites and animal attacks
- Abnormally dangerous or ultrahazardous activities
Each of these categories has its own specific elements that must be proven in order to establish liability.
Strict Liability for Defective Products
Strict product liability is perhaps the most common application of this doctrine. Under California law, manufacturers, distributors, and retailers can be held strictly liable if a defective product injures a consumer—even if they exercised care in making or selling it.
Elements of Product-Based Strict Liability
To succeed in a strict liability product claim, a plaintiff must prove the following elements:
The Defendant Manufactured, Distributed, or Sold the Product
Strict liability applies to any entity in the chain of distribution, including manufacturers, wholesalers, distributors, and retailers. Even if the seller did not create the defect, they may still be held liable.
The Product Was Defective
There are three recognized types of defects in California:
- Design defect: The product’s design is inherently unsafe, even if properly manufactured.
- Manufacturing defect: The product deviates from its intended design due to an error in production.
- Warning defect (failure to warn): The product lacks adequate warnings or instructions, making it dangerous to use.
The Product Was Defective When It Left the Defendant’s Control
The plaintiff must show that the product was already defective at the time it left the manufacturer or seller’s hands—not that it was altered or misused afterward.
The Plaintiff Used the Product as Intended or in a Reasonably Foreseeable Manner
Even if the plaintiff did not use the product exactly as intended, if their use was reasonably foreseeable, strict liability may still apply.
The Defect Caused Injury
There must be a direct link between the defect and the injury suffered by the plaintiff. This includes both physical injury and property damage.
Strict Liability for Animal Attacks
Under California Civil Code § 3342, dog owners are strictly liable for injuries caused by dog bites, regardless of the dog’s past behavior or the owner’s knowledge of potential danger.
Elements of Animal-Related Strict Liability
The Defendant Owned the Dog or Animal
The law only applies to the animal’s owner—not a temporary caretaker or landlord—unless specific circumstances apply.
The Animal Bit or Attacked the Plaintiff
In dog bite cases, the statute is clear: liability attaches when the dog bites someone, even if the bite is minor or occurred on the owner’s private property.
The Plaintiff Was Lawfully on the Property
Strict liability does not apply if the injured person was trespassing or unlawfully present on the property where the attack occurred.
While dog bite law is strict, owners of wild or exotic animals (e.g., tigers, wolves, poisonous snakes) may also face strict liability simply by virtue of owning a dangerous species.
Strict Liability for Ultrahazardous Activities
California courts may impose strict liability on individuals or companies that engage in activities considered abnormally dangerous. These are activities that carry an inherently high risk of harm and are not common in everyday life.
Elements of Activity-Based Strict Liability
The Defendant Engaged in an Abnormally Dangerous Activity
This includes but is not limited to:
- Using or storing explosives
- Demolitions and blasting
- Crop dusting with toxic chemicals
- Transporting hazardous materials
- Operating oil wells or chemical plants
The activity must be non-common, involve a high degree of risk, and not be safely conducted through ordinary precautions.
The Activity Caused Injury or Damage
The plaintiff must link the hazardous activity directly to the injury or damage. For instance, if debris from a demolition site injures a passerby, the construction company may be strictly liable.
Comparative Fault and Defenses in Strict Liability Cases
While strict liability eases the plaintiff’s burden in proving fault, it doesn’t mean defendants have no defenses. Common defenses include:
Misuse of Product
If a consumer used a product in a completely unforeseeable and unreasonable way, the manufacturer may argue that the defect did not cause the injury.
Assumption of Risk
If a plaintiff knowingly accepted the risks associated with the product or activity (e.g., continuing to use a product despite known warnings), their recovery may be reduced or barred.
Comparative Fault
California follows the rule of pure comparative fault, which applies even in strict liability cases. A plaintiff’s compensation may be reduced based on their percentage of fault.
Why Knowing the Elements Matters
Understanding the elements of strict liability is critical for both plaintiffs and attorneys. While the doctrine removes the need to prove negligence, you must still establish that:
- The product, animal, or activity was inherently dangerous or defective
- The defendant was responsible
- The harm was directly caused by that danger
Failing to establish just one of these elements can result in a case being dismissed. Thorough preparation, expert testimony (especially in product defect claims), and timely filing are key to success.
