What Is Product Liability Law?

Product liability law is a type of personal injury law that gives victims a legal cause of action when they’re hurt because of a dangerous product.

People and corporations who make products must make products that are safe.

Product liability is the area of law that governs what manufacturers must do to protect public safety and what rights victims have if they’re hurt because of a defective product.

Product liability law is also called product liability law.

Product Liability Law Is Part of Personal Injury Law

Product liability law is one part of personal injury law.

Personal injury law gives victims a civil cause of action when they get hurt because of the negligence of others.

Product liability is a subset of personal injury law that deals specifically with defective products.

Many standards and rules for product liability law are like all other personal injury cases.

However, in some ways, there are higher standards to protect victims who are hurt when products malfunction.

The Area of Product Liability Law

The purpose of product liability law is to require product manufacturers to bear the financial burden of producing a dangerous product.

A person or corporation that makes a product is responsible when it malfunctions.

The law makes the assumption that it’s more fair to require the product manufacturer to pay for the victim’s damages than to make the victim suffer the losses of getting hurt by a defective product.

In What Ways Can a Product Be Defective Under Product Liability Law?

There are multiple ways that a manufacturer can create a legally defective product:

Breach of Express Warranty

A manufacturer often includes warranties along with their product.

For example, if you buy a new car, the manufacturer might include a warranty that all of the parts work for three years or another period of time.

If a part breaks, the manufacturer might promise to fix it for free for the period of time covered under the warranty.

A breach of an express warranty can amount to a defective product.

Breach of Implied Warranty

All products include an implied warranty.

When you buy a product, it must work for the purpose it’s intended.

For example, if you buy a skillet, you expect to be able to cook with it.

If it starts on fire, you have a defective product.

The products that you buy must work for the main purpose of the item and for other reasonably foreseeable uses.

If a product fails to work like you expect it to, a defective product claim may be the remedy.

Manufacturing Defect

A manufacturer bears liability when there’s an error in the manufacturing process.

It’s not enough for the manufacturer to take reasonable care during the manufacturing process.

Instead, the manufacturer is strictly liable if there’s an error in the production process that causes harm to a victim.

Design Defect

Even if a product turns out as it’s intended, a manufacturer must still take care to design products that are safe for public use.

A design defect occurs when a manufacturer designs their product in a poor way.

To win a defective design case, the victim must show that the manufacturer could have designed a better product based on other designs that are available or possible at the time.

How to Prove a Product Liability Legal Claim

Like other personal injury cases, the victim of a defective product must prove that the product defect is the cause of their injuries.

The victim must prove all of the elements of negligence including a duty to create a careful product, a defect, a link between the defect, and injuries and damages.

If a product is defective, a victim may have consumer rights, but there must be an injury for the victim to have a product liability claim.

Unlike other personal injury negligence cases, the victim doesn’t have to prove why the product is defective.

It’s enough to show that the product is defective.

Information about how a product is defective is most likely in the hands of the product manufacturer, so the victim doesn’t have to prove what went wrong.

This type of liability is called strict liability.

The manufacturer is strictly liable for putting a defective product into the stream of commerce even if the victim can’t show how the product became defective.

Areas of Product Liability Law

Attorneys who practice product liability law must be skilled in a number of different areas of law.

Product liability law requires mastery of a diverse skill set that includes all of the following legal topics:
