[Restyled effective July 1, 2016.]

Advisory Committee Historical Note

Effective July 1, 2016, the Rule was amended as part of the general restyling of the Evidence Rules.

Effective June 16, 2016, the “Comment” was retitled “Advisory Committee Note.”

Advisory Committee Note

The language of Rule 704 has been amended as part of the general restyling of the Evidence Rules to make them more easily understood and to make style and terminology consistent throughout the rules. These changes are intended to be stylistic only. There is no intent to change any result in any ruling on evidence admissibility.

All reference to an “inference” has been deleted, on the grounds that the deletion made the Rule flow better and easier to read, and because any “inference” is covered by the broader term “opinion.” Courts have not made substantive decisions on the basis of any distinction between an opinion and an inference. No change in current practice is intended.

Rule 704 abolishes the “ultimate issue rule” which existed in pre-rule Mississippi practice. The ultimate issue rule was often unnecessarily restrictive and generally difficult to apply. More often than not the invocation of the rule served to deprive the trier of fact of useful information. Rule 704 clarifies much of

the confusion over the ultimate issue rule. An opinion is no longer objectionable solely on grounds that it “invades the province of the jury.”

The abolition of the ultimate issue rule does not result in the admission of all opinions. It is an absolute requirement under Rules 701 and 702 that opinions must be helpful to a determination of the case before they are admissible. Furthermore, under Rule 403 evidence is excluded which wastes time. A question may not be asked which is based on inadequately explored legal criteria since the answer would not be helpful. As the FRE Advisory Committee Note to FRE 705 indicates, the question in a will contest, “Did the testator have the capacity to make a will” is still not permitted, whereas the question, “Did the testator have sufficient mental capacity to know the nature and extent of his property and the natural objects of his bounty and to formulate a rational scheme of distribution” would be. The former question is not helpful; the latter is.

Rule 705. Disclosing the Facts or Data Underlying an Expert’s Opinion Unless the court orders otherwise, an expert may state an opinion – and give the reasons for it – without first testifying to the underlying facts or data. But the expert may be required to disclose those facts or data on cross-examination.

Rule 705 is an attempt to eliminate the use of the hypothetical question or, at the least, reduce its use. The almost universal criticism of the hypothetical question is that it is unduly complex and time-consuming. While dispensing with the requirement of preliminary disclosure at the trial of underlying facts or data,
