Invoking Cloture in the Senate

Cloture is the only procedure by which the Senate can vote to set an end to a debate
without also rejecting the bill, amendment, conference report, motion, or other matter it
has been debating.1 A Senator can make a nondebatable motion to table an amendment,
and if a majority of the Senate votes for that motion, the effect is to reject the amendment.
Thus, the motion to table cannot be used to conclude a debate when Senators still wish
to speak and to enable the Senate to vote for the proposal it is considering. Only the
cloture provisions of Rule XXII achieve this purpose. This fact sheet, one in a series of
fact sheets on legislative process, discusses the cloture procedure in the Senate. For more

There are several stages to the process of invoking cloture.
! First, at least 16 Senators sign a cloture motion (also called a cloture
petition) that states: “We, the undersigned Senators, in accordance with
the provisions of Rule XXII of the Standing Rules of the Senate, hereby
move to bring to a close the debate upon [the matter in question].”
! To present a cloture motion, a Senator may interrupt another Senator who
is speaking. When the motion is presented, the clerk reads it.
! The cloture motion then lies over until the second calendar day on which
the Senate is in session. For example, if the motion is filed on Monday,
it lies over until Wednesday, assuming the Senate is in session daily. If
the motion is filed on Friday, it lies over until Tuesday unless the Senate
was in session on Saturday or Sunday.
! The Senate votes on the cloture motion one hour after it convenes on the
second calendar day after the cloture motion was filed, and after a
quorum call has established the presence of a quorum. The time for the

cloture vote may be changed by unanimous consent, and the required
quorum call often is waived by the same means.
! The presiding officer presents the cloture motion to the Senate for a
rollcall vote at the time required by Rule XXII, even if the Senate had
been considering other business between the time the cloture motion was
filed and the time for voting on the motion arrives.
! The majority required to invoke cloture is three-fifths of the Senators
duly chosen and sworn, or 60 votes if there are no vacancies in the
Senate’s membership. However, invoking cloture on a measure or
motion to amend the Senate’s rules requires the votes of two-thirds of the
Senators present and voting, or 67 votes if all 100 Senators vote.
Senators who wish to offer amendments to a bill or amendment on which cloture has
been invoked must submit their amendments in writing before the cloture vote takes
place. First-degree amendments (which propose to change the text of a bill or a
committee amendment in the nature of a substitute) must be submitted in writing to the
journal clerk when the Senate is in session, but no later than 1:00 p.m. on the day after the
cloture motion is filed. Second-degree amendments (which propose to amend first-degree
amendments) must be submitted at least an hour before the Senate votes on cloture.

Cloture may be invoked only on a matter that is pending before the Senate or on the
unfinished business. It is not in order, except by unanimous consent, to invoke cloture
on a bill before the Senate has agreed to consider it. On the other hand, there is no limit
on the number of times that the Senate can vote on motions to invoke cloture on a bill,
amendment, or other matter it is considering.
If an amendment has been offered to a bill, the Senate may invoke cloture either on
the bill or on the amendment. Sometimes Senators prefer to invoke cloture on an
amendment instead of a bill because after the Senate invokes cloture, it may consider only
amendments that are germane. This germaneness requirement applies to amendments that
are pending at the time that cloture is invoked as well as to amendments that Senators
offer after the Senate has voted for cloture. Thus, if the Senate invokes cloture on a bill,
the presiding officer immediately rules on whether any pending amendment is germane.
If the amendment is not germane, it is not eligible for further consideration.
If the Senators who wish to expedite passage of a bill also support a pending
amendment to the bill, they cannot invoke cloture on the bill without also killing the
amendment they support. Their alternative is to ask the Senate to invoke cloture on the
amendment, not on the bill. Doing so protects the amendment from becoming subject to
the germaneness requirement. After the Senate agrees to the amendment, however, it may
be necessary for the Senate to invoke cloture a second time, on the bill as amended.
