MBE Rules · Torts

Products liability — strict liability

The rule

Manufacturer or seller in the business is strictly liable for harm caused by a product that is (1) defective (manufacturing, design, or warning), (2) defect existed when it left defendant's control, AND (3) caused plaintiff's harm in foreseeable use. Plaintiff need not be in privity.

In plain English

If a product is faulty and causes harm, the maker or seller can be held responsible, even if the buyer wasn't directly dealing with them and the product was used as expected.

Worked example

A coffee maker explodes due to a design flaw while being used normally, injuring a customer. The manufacturer is liable for the injuries, even though the customer bought it from a store, not directly from them.

Memory hook

Defect + Deliver = Damage. If it's defective at departure, you're on the hook for the harm.

The trap

Students think: Privity is required for liability. Wrong, because strict liability applies without privity. The actual test is defect, control, and causation.

How examiners test it

Test setup: product sold by reputable company, defect harms user. Trap: students focus on negligence or privity. Key is proving defect existed when product left defendant.
