Different court proceedings require different levels of proof. Understanding these standards helps forensic nurses understand the purpose of their testimony.
| Standard | Definition | Used In |
|---|---|---|
| Beyond Reasonable Doubt | Highest standard. No reasonable doubt of guilt. | Criminal trials (prosecution must prove) |
| Clear and Convincing Evidence | Middle standard. Highly probable or reasonably certain. | Some civil cases, termination of parental rights, civil commitment |
| Preponderance of Evidence | Lowest standard. More likely than not (>50%). | Most civil trials, protective orders |
Why this matters: A case that doesn’t result in criminal conviction (beyond reasonable doubt) may still succeed in civil court (preponderance). Forensic nurses may testify in both proceedings about the same case.
