Opinion Evidence

Legal Definition and Related Resources of Opinion Evidence

Meaning of Opinion Evidence

The general rule is that witnesses are only to be permitted to testify to matters of fact and it is for the court to make inferences from the facts proved and form its own opinion of the matter in issue . A witness will not be, as a rule, allowed to state his opinion on any matter before the court. However, the exception to this rule is the evidence of experts who are persons having peculiar skills and knowledge , derived from their education or experience or both on technical matters which the ordinary man cannot be expected to possess. Such is the testimony of a medical doctor in personal injury cases; the testimony of a pathologist on the cause of death where the same is in issue, etc. See federal rules of evidence 702 and 703, Appendix 5. Apart from the opinion of experts, a lay person may under limited circumstances be permitted to give his opinion as evidence where a judge finds that such opinions may be rationally based on the perceptions of the witness and that they are helpful to a clear understanding of his testimony or to the determination of the fact in issue. See Rule 56 (I) of uniform Rules of Evidence. Also, see Atwood v Atwood, 84 Conn. 169, 79 A. 59.
