This rule has been rescinded, which means it's no longer in effect. It was officially removed from the Pennsylvania Rules of Professional Conduct and no longer applies to attorneys practicing in the state.
If you're looking for guidance on this topic, you'll need to check whether another rule now covers the same subject matter, or consult with an attorney about current requirements. Rules get rescinded for different reasons, sometimes because the content moved to a different rule number, and sometimes because the rule was no longer needed.
Since this rule no longer has any legal effect, you can disregard it when thinking about attorney conduct standards in Pennsylvania. Any past cases or interpretations tied to this rule may still be historically relevant, but they don't reflect current law.
