Generally RONR or any other parliamentary authority is used for conducting meetings. Business such as elections and removal of members would occur at meetings. In any case, perhaps the bylaws could be amended to include the recommended language.
I'm not sure of the facts in this case, although Mr. Martin's interpretation seems reasonable to me. Perhaps Guest Lawrence Boze could clarify exactly what the bylaws say regarding these past presidents.
The adopted motion is in effect. The assembly could amend something previously adopted if it hasn't been executed. Or it could discipline the chair for not executing the motion.
