Rare that I would have cause to disagree with you MM, but on this occasion I would refer you to Model Standing Orders chapter 2:
DISORDERLY CONDUCT AT MEETINGS
a. No person shall obstruct the transaction of business at a meeting or behave offensively or improperly. If this standing order is ignored, the chair of the meeting shall request such person(s) to moderate or improve their conduct.
b. If person(s) disregard the request of the chair of the meeting to moderate or improve their conduct, any councillor or the chair of the meeting may move that the person be no longer heard or be excluded from the meeting.
c. The motion, if seconded, shall be put to the vote without discussion.
If a resolution made under standing order 2(b) is ignored, the chair of the meeting may take further reasonable steps to restore order or to progress the meeting. This may include temporarily suspending or closing the meeting.
I take your point of course and offer the extract direct from NALC MSOs as justification, whether you think that adequate or not only you can decide, the question is, "if" you accept the above text as appropriate, and if the vote is properly conducted and returns a majority, does the "no longer heard" relate solely to voice or would you interpret it to mean voice AND vote...
If you don't accept the principle of the action then the answer is obviously neither but maybe the MSOs reference will sway you to an opinion??
