Does negligence have to be proven in a successful strict liability case?

No, negligence does not need to be proven in a successful strict liability case. In strict liability cases, a defendant can be held liable for damages regardless of whether they acted negligently or with intent. This legal standard is often applied in cases involving inherently dangerous activities or defective products, where the focus is on the nature of the activity or product rather than the defendant's conduct. Therefore, the plaintiff only needs to demonstrate that the defendant's actions or product caused harm.
