Injured by a Defective Product?
The Manufacturer Pays.

Three Theories of Liability

New York recognizes three distinct legal theories under which an injured consumer can pursue a product liability claim, and understanding each one is essential to building the strongest possible case. These theories are not mutually exclusive — in fact, experienced product liability attorneys routinely assert all three in a single lawsuit to maximize the client's chances of recovery and to prevent the manufacturer from escaping liability through technical legal arguments.

The most powerful of these theories is strict liability. Under the landmark Codling v. Paglia (1973) decision from the New York Court of Appeals, manufacturers and sellers face strict liability for injuries caused by defective products. The injured party does not need to prove that the defendant acted negligently or carelessly. To prevail, the plaintiff must demonstrate three elements: that the product was defective, that the defect existed when the product left the manufacturer's control, and that the defect proximately caused the injury.

Strict liability is the most favorable theory for injured consumers. It eliminates the need to prove what the manufacturer did wrong during design or production — only that the product itself was defective and caused harm. As a result, the focus shifts from the manufacturer's conduct to the condition of the product. This is often far easier to prove with the right engineering and scientific experts.

Negligence is the second theory available in New York product liability cases. A negligence claim requires proof that the manufacturer, distributor, or seller failed to exercise reasonable care in the design, manufacture, testing, inspection, or labeling of the product. Unlike strict liability, negligence demands evidence of what the defendant actually did or failed to do. For example, the manufacturer may have skipped a quality control inspection, used substandard materials to cut costs, or ignored test results revealing a safety hazard.

Negligence claims are particularly effective when internal company documents reveal that the defendant knew about a risk and chose not to address it. Additionally, those documents often open the door to punitive damages.

Breach of warranty is the third theory, rooted in contract law rather than tort law. An express warranty arises when a manufacturer or seller makes specific representations about a product's safety, performance, or quality — through advertising, product labeling, or oral statements by a sales representative. If the product fails to conform to those representations and causes injury, the manufacturer has breached its express warranty.

The implied warranty of merchantability, codified under UCC §2-314, requires that every product sold be fit for its ordinary purpose. The implied warranty of fitness for a particular purpose under UCC §2-315 applies when the seller knows the buyer's specific intended use. In that situation, the buyer relies on the seller's expertise in selecting the product. Breach of warranty claims can be especially valuable when the strict liability theory faces procedural obstacles, because warranty claims carry their own distinct statute of limitations and notice requirements.

Three Types of Product Defects

Manufacturing defects occur when an individual product deviates from its intended design during production. This makes that specific unit dangerous even though the overall design is sound. These defects are often the most straightforward to prove because the plaintiff can compare the defective product to the manufacturer's own design specifications or to other units from the same production run.

For example, manufacturing defects include a batch of medication contaminated during compounding, a car with an improperly installed brake caliper, a bicycle frame with a weld that failed quality standards, or infant formula that was not properly sterilized. Manufacturing defects typically affect only a subset of products rather than the entire product line. They frequently result in recalls once the scope of the problem becomes apparent.

Design defects differ fundamentally from manufacturing defects. The product was manufactured exactly as intended — the problem is that the design itself is unreasonably dangerous. Every unit that rolls off the production line carries the same flaw. New York courts evaluate design defect claims using the "risk-utility" test. The key question: would a reasonably prudent manufacturer have chosen an alternative design that reduced or eliminated the injury risk without substantially impairing the product's utility?

This analysis considers the gravity of the danger, the likelihood of injury, the feasibility of an alternative design, the cost of implementing it, and the effect on the product's usefulness. In practice, design defect cases often involve rollover-prone SUVs where a lower center of gravity was feasible, power tools without adequate blade guards, children's products with small detachable parts posing choking hazards, and pharmaceutical drugs with unreasonable side effects when safer compounds exist.

Marketing defects — commonly referred to as "failure to warn" claims — arise when a product lacks adequate instructions, safety warnings, or hazard disclosures about risks the manufacturer knew or should have known about. A product that is perfectly designed and perfectly manufactured can still be legally defective if the manufacturer fails to communicate foreseeable risks to the end user.

These claims are especially common in pharmaceutical cases, where manufacturers must disclose known side effects and contraindications. They also arise in power tool cases involving inadequate kickback warnings and in chemical exposure cases where cleaning products, pesticides, or industrial solvents lacked warnings about inhalation, skin contact, or use in enclosed spaces. The adequacy of a warning is judged by whether it would alert a reasonable consumer to the specific risk of harm.

Who Is Liable in the Supply Chain

One of the most consumer-protective aspects of New York product liability law is that strict liability extends to every entity in the chain of distribution — not just the manufacturer. Component part suppliers, the assembler or finished product manufacturer, distributors and wholesalers, and the retail store that sold the product to the consumer can all face strict liability for injuries caused by the defect.

The injured party can sue the retailer even though the retailer had no involvement in the product's design, manufacturing, or quality control. This principle is particularly important in today's global economy. Many consumer products are designed in one country, manufactured in another, and sold by domestic retailers and online marketplaces. When the manufacturer is a foreign entity with no U.S. presence, the domestic retailer or importer is often the most accessible defendant. New York law ensures that the injured consumer still has a viable path to recovery.

New York also recognizes the doctrine of successor liability, which becomes relevant when a company acquires another company that manufactured a defective product. In many cases, the acquiring company inherits the product liability obligations of the company it purchased. This applies when the acquisition was structured as a merger, when the acquiring company is merely a continuation of the original manufacturer, or when the transaction was designed to escape liability.

Successor liability prevents manufacturers from avoiding responsibility for dangerous products simply by restructuring their corporate entities. Our firm traces corporate lineages, merger agreements, and asset purchase documents to identify every entity that bears responsibility for a client's injuries. No potentially liable party escapes accountability.

Statutes of Limitations

The general statute of limitations is 3 years from the date of injury (CPLR §214). For latent injuries — particularly toxic exposure cases like asbestos — CPLR §214-c provides a discovery rule, starting the clock when the injured party knew or should have known about the injury. Claims against government entities may require a Notice of Claim within 90 days.

Comparative Negligence & Multi-Defendant Liability

Under CPLR §1411, New York applies pure comparative negligence — your recovery may be reduced by your share of fault but is never eliminated entirely. In product liability cases, all parties in the distribution chain can be held liable: the manufacturer, distributor, wholesaler, and retailer. This is critical when the manufacturer is a foreign company or has gone bankrupt.

Regulatory Framework

Federal agencies like the Consumer Product Safety Commission (CPSC) and FDA issue recalls and safety standards that can serve as powerful evidence in your case. Our firm monitors recall databases, CPSC enforcement actions, and FDA adverse event reports to build the strongest possible claim.

Product liability litigation is among the most complex and resource-intensive areas of personal injury law. The process begins long before a complaint is filed with the court. The single most important step in any product liability case is the preservation of the defective product. If the product is lost, destroyed, repaired, or altered before experts can examine it, the case may be fatally compromised.

Courts take spoliation of evidence extremely seriously. A party that destroys or fails to preserve relevant evidence can face adverse inference instructions, monetary sanctions, or even dismissal. Our firm sends immediate preservation letters to every party that may possess relevant evidence. We also arrange for the defective product to be secured, photographed, and stored under controlled conditions for expert examination.

The next phase is expert retention. Product liability cases are won and lost on expert testimony. Depending on the nature of the defect, our firm retains mechanical engineers, electrical engineers, materials scientists, metallurgists, human factors experts, toxicologists, pharmacologists, and medical specialists. These experts examine the product, identify the defect, explain how it caused the injury, and testify that a safer alternative design or adequate warning would have prevented the harm. They also conduct destructive and non-destructive testing, review the manufacturer's design history files, and prepare detailed written reports that form the backbone of the case.

Once the investigation is complete, we file a complaint naming every entity in the chain of distribution as a defendant — the component part manufacturer, the assembler, the finished product manufacturer, distributors, and the retailer. The discovery phase that follows is where product liability cases gain their most decisive evidence.

We serve document demands requiring the manufacturer to produce design documents, engineering specifications, testing protocols, quality control records, internal memoranda about known defects, customer complaint files, warranty claim data, and prior lawsuit records. We also depose corporate representatives under Federal Rule 30(b)(6) — including design engineers, quality control managers, and executives. These depositions compel them to testify under oath about what the company knew about the defect and when they knew it.

Many product liability cases — particularly those involving medical devices, pharmaceuticals, and automotive defects — are consolidated in multi-district litigation (MDL) proceedings before a single federal judge for coordinated pretrial proceedings. MDL consolidation streamlines discovery and avoids inconsistent rulings across different courts, but it also creates unique strategic considerations. Our firm has experience navigating MDL proceedings and ensuring that our individual clients' cases receive the attention and advocacy they deserve within the larger consolidated action. Cases that do not settle during or after MDL proceedings are remanded to their original courts for trial, where a jury hears the evidence and determines liability and damages.
