What role does a plaintiff have in cases where the doctrine of res ipsa loquitur is applied?

The principle of res ipsa loquitur, which translates to "the thing speaks for itself," applies in situations where the circumstances surrounding an injury imply negligence without direct evidence. In cases where this doctrine is invoked, the role of the plaintiff focuses significantly on establishing that they had no control over the situation leading to their injury.

Specifically, for res ipsa loquitur to apply, it typically must be shown that the event causing harm is of a kind that ordinarily does not occur in the absence of negligence, and that the plaintiff did not contribute to the cause of the injury. Thus, the plaintiff's lack of involvement or contribution to the situation that resulted in harm is critical. This absence of causal role strengthens the inference that negligence likely occurred, allowing the case to proceed without the necessity of direct proof of negligence.

In contrast, establishing direct causation, proving negligence explicitly, or filing a counterclaim are not central to the application of res ipsa loquitur. Instead, the focus remains on the idea that the plaintiff’s situation was one of passive involvement, and the facts suggest that negligence is the reasonable assumption.
