"Prima Facie" is a Latin term meaning "at first glance" or "on its face." In legal contexts, it refers to evidence that is sufficient to establish a fact or raise a presumption unless disproven. For example, if a person is found at the scene of a crime with a weapon, this may serve as prima facie evidence of their involvement. In broader usage, prima facie can apply to any situation where initial evidence or arguments appear to support a conclusion. It allows for a preliminary assessment before deeper investigation or analysis, helping to guide decision-making in various fields, including law, ethics, and research.
