If I can quote:
The chair cannot adjourn the committee on his or her own authority; only the committee can decide when it will adjourn. The chair may ask if the committee is ready to adjourn and if no one objects or wishes to keep speaking then the chair may adjourn the committee. Many chairs and members do, however, believe that the chair has this authority and a number of chairs have acted on that belief. In the event of disorder, the chair may suspend the meeting until order can be restored. Or if the situation is considered to be so serious as to prevent the committee from continuing with its work, the meeting may be adjourned.
So if you get too rowdy, obviously I can adjourn the meeting. If you stay civil, then you heard the ruling.
This is a handbook used by clerks to find citations. They're now going to give you chapter and verse and the whole bit you want. Just one minute.
Yes, Mr. Cullen.
