A proposed professional conduct rule that could subject attorneys to disciplinary action for behavior considered harassment or discrimination has been rejected by the states of Arizona and Idaho, the latest in a growing group of states that have refused to accept the rule.

The state supreme courts in Arizona and Idaho voted recently to shoot down a proposed anti-discrimination amendment to their states’ rules of professional conduct for lawyers. The Arizona Supreme Court rejected the rule on Aug. 30, while Idaho’s high court took a similar action on Sept. 6.
