How is "proximate cause" established in negligence cases?

In negligence cases, establishing "proximate cause" involves demonstrating a direct link between the defendant’s actions and the plaintiff's injuries, specifically indicating that the injury was a foreseeable result of those actions. This means that the act leading to the injury must have been a significant factor in bringing about the harm. The concept of proximate cause serves to limit liability to those outcomes that are closely connected to the negligent conduct, as opposed to those that are more distant or disconnected.

A direct link implies that there must not be any intervening causes that break the chain of causation, meaning no other events should interfere between the defendant’s action and the resulting injury that would render the connection irrelevant. This illustrates the importance of foreseeability in legal standards for negligence, ensuring that defendants are only held responsible for consequences that can be reasonably anticipated as a natural outcome of their actions.

In contrast, proving the plaintiff's own negligence does not establish proximate cause; it might instead contribute to comparative negligence defenses. Demonstrating that an injury is unlikely to occur or relying solely on eyewitness testimonials does not inherently establish the requisite causal connection needed to prove proximate cause in negligence.
