Ariz. R. Evid. 705

As amended through December 6, 2023

Rule 705 - Disclosing the Facts or Data Underlying an Experts 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.

Ariz. R. Evi. 705

Amended Oct. 19, 1988, effective 11/1/1988; 9/3/2009, effective 1/1/2010; 9/8/2011, effective 1/1/2012.

COMMENT TO 2012 AMENDMENT

The language of Rule 705 has been amended to conform to the federal 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.

The 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.
