This report presents a brief explanation of the House's rules and procedures relating
to the quorum requirements applicable on the House floor. Additional and more
authoritative information may be found in the commentary accompanying pertinent
House rules and appearing in the most recent edition of the House rules manual, formally
entitled Constitution, Jefferson's Manual and Rules of the House of Representatives.
For the most part, the Constitution empowers the House of Representatives and the
Senate to establish the procedures by which each house conducts its legislative business.
Under section 5, clause 2, of Article I, "[e]ach House may determine the Rules of its
Proceedings." However, there are certain exceptions to this discretionary authority,
including a provision of the immediately preceding clause stating that "a Majority of each
[House] shall constitute a Quorum to do Business; but a smaller Number may adjourn
from day to day, and may be authorized to compel the Attendance of absent Members, in
such Manner, and under such Penalties as each House may provide."
So the Constitution stipulates that a quorum for House floor proceedings is a simple
majority of the membership, or 218 of the 435 Representatives (assuming that there are
no vacancies in the House). Furthermore, the Constitution would appear to require that
this majority of Representatives actually must be present on the floor whenever the House
is conducting legislative business, with the limited exception for adjournments and related
proceedings. Yet any observer of the House will notice that it is quite unusual for 218
Members to be on the floor at the same time. In fact, it would be extremely difficult for
the House's committees as well as its individual Members to meet all their official
responsibilities if a majority of Representatives had to be present at every moment that the
House is in session. How then does the House reconcile its practices with the
constitutional requirement of Article I?

There are essentially two devices that the House has developed to give itself valuable
flexibility in complying with the constitutional quorum requirement. One involves reliance
on the Committee of the Whole; the other involves the definition of "business" that a
quorum must be present to conduct.
The Committee of the Whole
The House conducts much of its business on the floor by constituting itself into a
committee on which all Representatives serve. The full title of this committee is the
Committee of the Whole House on the State of the Union, but it is known simply as the
Committee of the Whole. The constitutional quorum requirement does not apply during
meetings of this committee because technically they are not meetings of the House of
Representatives. So the House has decided for itself what the quorum in this committee
should be. The rules of the House state that the quorum needed during meetings of the
Committee of the Whole is only 100, compared with the 218 Members who constitute a
quorum of the House.
All Representatives are members of the Committee of the Whole and it meets in the
House chamber. In fact, the only immediately noticeable difference between a meeting of
the House and a meeting of the Committee of the Whole is that the Speaker does not
preside over a meeting of the Committee; he designates another member of the majority
party to preside as chairman of the Committee of the Whole during floor consideration of
one particular bill. The position of chairman is not a permanent one; the Speaker appoints
different members of his party as chairman at different times.1
In most circumstances, not having to preside over the Committee of the Whole
actually is advantageous for the Speaker because it gives him the freedom to use his time
in ways that may be more productive in meeting his many institutional and political
responsibilities. Once the House has begun consideration of a bill, there is relatively little
that the Speaker (or the chairman of the Committee of the Whole) can do from the
rostrum to affect what happens to it. While he is presiding, for example, the Speaker
never participates in debate from the chair, nor does he make any comments at all about
the policies that are being debated. He also is expected to apply and enforce the House's
rules and precedents in a fair and even-handed manner. The same expectations govern
chairmen in the Committee of the Whole.
When the House considers a major bill on the floor, the overwhelming majority of its
time and work almost invariably takes place in the Committee of the Whole. Actually, a
four-stage process is involved. All four stages may take place without interruption, or
they can occupy part of the House's time over a period of several days or longer.
1 When the House becomes ("resolves itself into") the Committee of the Whole, the mace, which
is the symbol of the authority of the House, is moved to a lower place on the Speaker's rostrum.
It also should be noted that the Speaker does not always preside over the House; he often asks
another member of the majority party to preside temporarily in his absence.
First, the House decides to consider a particular bill and then transforms itself into the
Committee of the Whole for that purpose.2
Second, to begin the process of consideration in the Committee of the Whole, there
is a period of time set aside for what is known as general debate—for debating the general
merits of the bill and the issues it addresses. No amendments may be offered during
general debate, although Representatives frequently describe amendments that they intend
to offer at the next stage of the proceedings.
Third, while continuing to meet in the Committee of the Whole, there usually is an
opportunity for Representatives to propose amendments to the bill. Each Member
typically may be able to debate each amendment for five minutes. Representatives
normally must offer their amendments to each section of the bill in sequence. However,
the Committee of the Whole has no authority actually to amend the bill. Instead, it votes
on whether it wishes to recommend each amendment to the House because only the
House, not the Committee of the Whole, can vote to amend legislation. It is this
fact—that the Committee of the Whole cannot amend legislation—that allows the House
to assert that the Committee of the Whole is another form of committee and is not simply
the House meeting under a different name.
Fourth and finally, when the Committee of the Whole has voted on the last
amendment to the last portion of the bill, it transforms itself back into the House of
Representatives and the Speaker once again presides. The House then votes on whether
to formally adopt the amendments that had received majority votes in the Committee of
the Whole. And finally, the House votes on whether to pass the bill as it may have been
amended during this process. So it is the House itself that actually votes on whether to
amend and pass the bill, but virtually all the debate and all the preliminary votes on
amendments take place in the Committee of the Whole.
Because of the House's heavy reliance on the Committee of the Whole, the quorum
requirement that usually must be satisfied on the floor is not 218, which is a majority of
the total membership of 435, but only 100, which is the quorum that the House has
established in its own rules to apply in the Committee of the Whole. In theory, at least,
the House could reduce the quorum requirement in the Committee of the Whole to any
level it chooses—to 10 instead of 100 members, for example—though it has been 100 for
more than a century.
The Presumptive Quorum
The House presumes that a quorum always is present, whether in the House or in the
Committee of the Whole, unless the absence of a quorum is demonstrated conclusively,
either by a quorum call or by a record vote. This is a reasonable and appropriate
presumption because the alternative would be to presume that the House is not complying
with the Constitution.
2 This normally is done under the authority of a resolution (known as a rule or special rule) that the
House adopts at the recommendation of the Committee on Rules.
Furthermore, it is not the Speaker's (or the chairman's) responsibility to ensure that
a quorum is present, and he never is required to take the initiative to count to determine
the presence of a quorum. Instead, any Member can demand that the roll be called to
demonstrate that a quorum is present. In recent years, however, the House has amended
its rules to limit the occasions when Members are allowed to demand quorum calls. The
effect of these rules changes has been implicitly to narrow the definition of the "business"
that a quorum must be present to conduct, according to the Constitution.
To summarize the effect of a complicated body of rules, about the only time that a
Representative has a right to challenge the presumption that a quorum is present is when
a vote is taking place. At almost all other times, it is left to the discretion of the Speaker
or the chairman of the Committee of the Whole to decide whether to permit a request for
a quorum call or to entertain a point of order that a quorum is not present. In this way,
the House can meet on the floor with few Members present. When a vote takes place,
Members come to the chamber to record their presence, but then they can leave again until
the next vote occurs.
It is equally important to observe that Representatives do not enforce the applicable
quorum requirements as often as the House's rules still permit. Quorum calls and record
votes occur in connection with only a small fraction of all the votes that take place on the
House floor. The first vote taken on any question is a "voice" vote: all those in favor of
agreeing to the question call out "Aye," followed by those opposed who call out "No."
The Speaker (or the chairman of the Committee of the Whole) then decides which side
prevailed. This vote is final and valid even if there are very few Representatives present
and voting so long as no one objects to the vote on the ground that a quorum was not
present. The presumption in this situation is that a quorum (whether 218 in the House or
If any Member is dissatisfied with how the Speaker or chairman heard the voice vote,
he or she can demand a division vote. In this case, those in favor stand and are counted,
followed by those opposed. The Speaker or chairman then announces how many
Representatives voted on each side, and this vote also is final and valid, even if the total
number of Members voting do not constitute a quorum—again, unless a Member objects
to the vote on the ground that a quorum was not present. The presumption in this case
is that a quorum was present on the floor even if not all of those Members chose to vote.
The House interprets the Constitution to require that a quorum be present, not that a
quorum actually vote. As the House Parliamentarian has stated in his commentary on the
House’s rules, "[a] vote by division takes no cognizance of Members present but not
voting, and consequently the number of votes counted by division has no tendency to
establish a lack of a quorum."
Whether in the House or in the Committee of the Whole, any Member can object to
any voice or division vote, making the point of order that a quorum was not present. In
that case, the Speaker or chairman counts to determine whether a quorum is on the floor.
If it is not, what occurs depends on whether it is a meeting of the Committee of the Whole
or a meeting of the House that is taking place. In the Committee of the Whole, there first
is a quorum call, which may be followed by a record vote on the pending question if
enough Members request it. In the House, there is a record vote on the pending question;
by casting their votes on this question, Members also document the presence of a quorum.
To repeat, though, most votes that take place on the House floor do not provoke a record
vote, either because they are routine and non-controversial, or because their outcome is
not in doubt and Members are reluctant to inconvenience all their colleagues unnecessarily
by requiring them to come to the floor for a quorum call or a record vote.
