Final answer:
Strict liability is the type of liability that does not require proof of negligence; manufacturers can be held responsible for injuries caused by known defects in their products.
Step-by-step explanation:
The type of liability where the injured party does not need to prove negligence is known as strict liability. In cases of strict liability, a manufacturer may be held liable for injuries caused by a defective product without the injured party having to show that the manufacturer was negligent. A counter example situation where a car manufacturer knows of a brake defect in a model but still proceeds with its production can lead to strict liability claims when the defect causes injuries or deaths.
