Definition & Meaning

The common-knowledge exception is a legal principle that allows certain types of testimony in medical malpractice cases without the need for expert witnesses. This exception applies to situations where the alleged negligence is so clear that a layperson can understand it without specialized knowledge. Essentially, if the circumstances surrounding the case are straightforward enough, the court may allow a plaintiff to present evidence without needing expert testimony to establish negligence.

Legal Use & context

The common-knowledge exception is primarily used in civil law, particularly in medical malpractice actions. It allows plaintiffs to bypass the typical requirement for expert testimony in cases where the negligence is evident to an average person. This can streamline the legal process and make it easier for individuals to pursue claims without the added burden of hiring experts.

Key legal elements

Real-world examples

Here are a couple of examples of abatement:

(Hypothetical example) A patient undergoes a routine procedure, and the medical staff fails to follow basic hygiene practices, leading to an infection. In this case, the negligence is apparent and does not require expert testimony to understand.

(Hypothetical example) A surgeon leaves a surgical tool inside a patient. This is a clear instance of negligence that an average person can recognize without needing expert input.
