Strict Liability

“Strict liability” means legal responsibility for an injury or loss irrespective of the defendant’s state of mind or whether the defendant’s conduct was negligent, reckless or intentional. In dog bite law, the “one bite rule” imposes strict liability on a dog owner or harborer who knows or reasonably should know that his dog either bit a person without legal justification or acted like it wanted to, if the dog thereafter bites someone. See generally, Legal Rights of Dog Bite Victims in the USA

Even if an act or failure to act or warn results technically in strict liability, the defendant might still have defenses available such as assumption of the risk or provocation.
