ABSENCE OF A QUORUM
The absence of a quorum occurs when it is officially demonstrated
that the number of Members required to conduct business is not present
on the House or Senate floor. If a quorum call or roll-call vote
demonstrates that a quorum is not present, no further debate or other
business may be transacted, except a motion to adjourn or a motion to request
or require the attendance of absent Members. In the House, the chair can
count the Members who are on the floor to determine if a quorum is
present. The presiding officer in the Senate usually does not have
this authority.
In the Senate, a quorum call is called off by unanimous consent before
all Senators' names have been called. The absence of quorum has not been
demonstrated, and the Senate may resume its business.
