McDaniel v. Payson Healthcare Management, Inc.Annotate this Case
In this medical malpractice case, the Supreme Court held that defendants do not violate the "One-Expert Rule" when offering the testimony of a treating physician on the standard of care, in addition to that of a retained or specially employed expert, when the testimony is based on the treating physician's personal observations and participation in providing treatment to the plaintiff.
At issue was the One-Expert Rule set forth in Ariz. R. Civ. P. 26-(b)(4)(F)(i), which allows each side in a medical malpractice case presumptively to call only one retained or specially-employed expert to testify on the standard of care issue. The Supreme Court remanded this case for a new trial, holding (1) the trial court correctly declined to find a violation of the One-Expert Rule in this case; and (2) a treating physician dismissed on summary judgment is not an indispensable party to an appeal of the denial of a motion to name him a nonparty at fault.
