I think p. 571 #4 might apply as well, depending on the interpretation, which is of course the responsibility of our Guest's organization. If they were to decide that "voice" meant strictly the ability to engage in debate, and not to make motions nor second them, then the granting of the right to enter into debate, enumerated as such in the bylaws, would seem to restrict from the member the rights (of the "same class") to make and second motions. The best option here, it seems to me, is to amend the bylaws to state explicitly what the intent is, which I suspect is merely to restrict the member from voting, which is easily done by stating that mere fact alone, and leaving out any qualification.
