Scientific Evidence Law and Legal Definition

Scientific evidence refers to the evidence presented in a court after scientific tests or studies. It serves to support or counter a scientific theory or hypothesis. Scientific evidence is the result of objective testing of a theory or hypothesis in a way that can be reproduced by others. For example, test in an experiment or controlled trial.

Competent and reliable scientific evidence means tests, analyses, research, studies, or other evidence based on the expertise of professionals in the relevant area, that has been conducted and evaluated in an objective manner by persons qualified to do so, using procedures generally accepted in the profession to yield accurate and reliable results.
