Common questions
Can a witness of fact ever offer any kind of inference in testimony?+
Courts generally allow narrow, common-sense inferences a lay person would ordinarily draw from what they observed, such as estimating that a person seemed intoxicated, but they may not draw inferences that require specialist training or technical analysis, which is reserved for expert witnesses.
Why does the fact versus expert witness distinction matter procedurally?+
Expert witnesses are typically subject to separate qualification, disclosure, and report requirements that do not apply to witnesses of fact, so misclassifying a witness's role can lead to their testimony being excluded or challenged on procedural grounds.
