The common law--as interpreted by Arizona courts in the light of reason and experience--governs a claim of privilege unless any of the following provides otherwise:
* the United States or Arizona Constitution;
* an applicable statute; or
* rules prescribed by the Supreme Court.
Ariz. R. Evi. 501
COMMENT TO 2012 AMENDMENT
The language of Rule 501 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.
