Senate Rules and Practices on Committee,
Subcommittee, and Chairmanship Assignment
Limitations as of November 4, 2000
Summary
Senate Rule XXV and party practice limit the number and types of committee
and subcommittee assignments a Member may hold. The rule sets the size of each
committee, and Senate tradition dictates that, in most instances, party ratios in
committee reflect the overall party ratio in the chamber. Both parties utilize Member
seniority, state represented, and ideology as factors influencing committee
assignments.
Rule XXV divides committees into three classes, characterized as A, B, and C.
Class A consists of 12 standing committees; class B includes four standing
committees, two select committees and one joint committee; and class C includes two
select or special committees and three joint committees.
Normally, each Senator would be assigned to three committees (two in class A
and one in class B) and eight subcommittees (three on each class A committee, and
two on the class B committee). There are no limitations on assignments to class C
panels.
However, under exceptions often granted in the rule (called “grandfather
rights”), some Senators have additional committee and subcommittee assignments.
This report details these limitations and exceptions.

Senate Rules and Practices on Committee,
Subcommittee, and Chairmanship Assignment
Limitations as of November 4, 2000
Introduction
By standing rule, the Senate limits the number and types of committee and
subcommittee assignments a Member may hold. The rule (Rule XXV, paragraphs 2,
3, and 4)1 further sets the size of each committee. Decisions on Senate committee and
subcommittee assignments involve many other factors as well. Both parties utilize
Member seniority, state represented, and ideology as factors influencing assignments
to committees. Senate traditions further dictate that, in most instances, party ratios
in committees reflect the overall party ratio in the chamber.
The comprehensive and complex system of limitations began to evolve at least
100 years ago. By the second half of the 19th century, for example, it was already an
accepted, although informal, practice that no Senator should chair more than one
legislative committee. The Legislative Reorganization Act of 1970 incorporated a
slightly more restrictive version of that practice into the standing rules. Previously,
chairs of standing legislative committees sometimes also chaired joint, select, or
special committees. The 1970 rule prohibited Senators from chairing more than one
committee of any kind, with two exceptions: (1) a standing committee chair may also
chair a joint committee the jurisdiction of which is directly related to that of the
standing committee, and (2) a chairman may also chair one temporary committee or
temporary joint committee (not including conference committees). The prohibition
in force today—adopted on February 4, 1977, when the Senate agreed to S.Res. 4 of
the 95th Congress—continues the first exception but reflects a small change to the
second (See Section III of this report.)
Early in the 20th century, both parties in the Senate adopted informal practices
intended to distribute committee assignments, especially to prestigious committees,
more equitably. Dissatisfaction with the results led to the adoption of formal, more
elaborate limitations in the Legislative Reorganization Act of 1946. The new rule
limited each Senator to membership on two so-called major standing committees.
However, majority party Senators—and later all Senators—were permitted additional
assignments on so-called minor standing committees. In addition, Senators could
serve on any number of special, select, and joint committees.

The Legislative Reorganization Act of 1970 introduced a more comprehensive,
yet complex and restrictive, system. All committees were subjected to the limitations
code and divided among three classes. Senators were required to serve on two
committees in the first class and permitted to serve on one in each of the other classes.
To assure majority-party control of all committees in a closely divided Senate,
Senators could receive temporary assignments to a fifth committee. Exceptions in the
form of “grandfather rights” were granted to protect the assignments of Senators
sitting on more than the prescribed number of committees before the effective date
of the act, January 3, 1971.
Over the years, the Senate granted extensions of grandfather rights, permitted
some Senators to serve on additional committees without losing other assignments,
and exempted certain committees from the limitations rules. These actions permitted
some Senators a larger number of committee assignments than they otherwise might
have held under the Legislative Reorganization Act’s limitations.
During its comprehensive review of committee operations, the 1976 Temporary
Select Committee to Study the Senate Committee System, chaired by Adlai Stevenson
III, D-Ill., found that the average number of committee and subcommittee
assignments per Senator had more than tripled in 30 years. For example, in 1947 each
Senator served on approximately five panels; in 1976, that number had increased to
19. The select committee concluded that this proliferation of assignments was
responsible for “an inefficient division of labor, uneven distribution of responsibility,
conflicts in the scheduling of meetings, waste of Senators’ and staff time,
unsystematic lawmaking and oversight, inadequate anticipation of major problems,
and inadequate membership participation in committee decisions.” 2 It was in this
atmosphere that the Senate agreed to S.Res. 4, 95th Congress, which incorporated
the new assignment limits into the Senate rules.
The 1977 revision of the rules continued the three-class committee structure of
1970, changed the composition of the classes somewhat, and eliminated the overall
limitation on assignments in the third class. The rules revision also retained the
mechanism for temporary additional assignments to assure majority party control of
committees. Although S.Res. 4 retained the concept of grandfather rights, most
expired at the start of the 96th Congress. However, the provisions allowing the
former chairs and ranking minority members on two abolished committees (the
District of Columbia Committee and the Post Office and Civil Service Committee) to
serve on the Committee on Governmental Affairs in addition to other assignments had
no expiration date. In addition, new temporary grandfather rights were created at the
beginning of the 96th Congress and at the beginning of every Congress since.
S.Res. 4, the Committee System Reorganization Amendments of 1977, also
removed the limitations on assignments to prestigious or exclusive committees. These
limitations had started as informal party practice and were converted into formal rules
by the Legislative Reorganization Act of 1970. Both parties, nevertheless, continue

to enforce limitations on assignments to exclusive committees, although they differ
somewhat on the committees they regard as exclusive, as explained in Section I.
Restrictions on the Senate’s subcommittee structure were first adopted in the
1970 act and dealt only with subcommittee chairmanships. With the proviso that
Senators might continue to occupy all such chairmanships held as of January 3, 1971,
and continuously thereafter, no Senator was to serve as chair of more than one
subcommittee of any of his or her “class A” committees (see Section I). S.Res. 4 of
1977 eliminated the grandfather rights of 1970 and extended the prohibition on
subcommittee chairs to all committees. It also inaugurated limitations on
subcommittee assignments, in most cases allowing Members to serve on three
subcommittees of each “class A” committee, and two subcommittees of each “class
B” committee.
The transfer of majority-party status to the Republicans as a result of the 1980
elections, changes recommended by the 1984 Select Committee on Committees, the
return of the Democrats to majority-party status in 1986, and the transfer of majority-
party status to the Republicans as a result of the 1994 elections necessitated further
temporary modifications to the assignment provisions and the adoption of new
grandfather rights. The balance of this report describes the current limitation
provisions.
I. Full Committee Assignments
Paragraphs 2, 3 and 4 of Senate Rule XXV, in effect, create three groups of
committees for assignment limitation purposes. For easier identification, these groups
are referred to below as classes A, B, and C, even though they are not so labeled in
the rule.
Subject to various exceptions in the rule, in resolutions, and in party regulations,
Rule XXV limits assignments in each class as follows:
! Each Senator shall serve on two committees, and no more than two, in class
A. This group consists of 12 standing committees.
! Each Senator may serve on one committee, and no more than one, in class B.
This group includes four standing committees, two permanent select and
special committees, and one joint committee.
! Each Senator may serve on one or more committees in class C. This group
includes a standing committee, a permanent special committee, and three joint
committees.

Each Senator shall (must) serve on two, but not more than two, of the
committees listed above, except that some Senators may serve on as
many as three or four of them under the following conditions.4
(1) Great-Grandfather Rights: Any Senator who (1) on February
10, 1977, was serving as chairman or ranking minority member

may transfer from one committee to another and still retain three
class A assignments so long as the Senator maintains continuous
service on Governmental Affairs. This exception has no
expiration date.5

(2) Combinations of Certain Class A Committees: Senators who
were sitting on certain combinations of two class A committees
at the end of the 95th Congress were granted assignments to
specified third class A committees for the remainder of their
current Senate terms so long as their service on each of those
committees is continuous. However, Senators who sit on three
class A committees under this exception may not serve on any
other class A committees, or the class B Budget Committee,
even if they are eligible to do so under some other exception.6
The specified combinations of class A committees for the 106th
Congress were not included in the assignment resolutions for the
106th Congress.
(3) Party Ratios: Senators of the majority party may be assigned to
three class A committees when the majority and minority leaders
agree to a temporary increase in the size of a class A committee
in order to assure majority party control of that committee. Such
assignments are temporary and are to be relinquished once the
need for the increase in the committee’s size is past. No class A
committee may be increased in size, under this exception, by
more than two members in excess of the number prescribed for
that committee by paragraph 2 of Rule XXV.7
b.
Republican Exclusive Committees: By Republican Conference rule,
no Republican Senator may serve simultaneously on more than one of
the following four exclusive committees:
Appropriations
Armed Services
Finance
Foreign Relations8
c.
Democratic Exclusive Committees: Under a Democratic Conference
regulation of 1975, as modified in February 1977, no Democratic
Senator may serve simultaneously on more than one of the following
five exclusive committees:

Basic Conditions
a.
A Senator may serve on one, but not more than one, of the
committees listed above, although he is neither required nor entitled
to serve on such a committee, except:14
(1) Class A Great-Grandfathers: A Senator who sits on the
Governmental Affairs Committee, plus two other class A committees,
because he was formerly chairman or ranking minority member of the
District of Columbia or Post Office and Civil Service Committee, may
not serve on any class B committees, except the Committee on Rules
and Administration.15
(2) Budget Plus Two Class A Assignments: A Senator assigned to the
Budget Committee and two class A committees may not serve on any
other class B committee.
(3) Intelligence Committee: No Senator may be assigned to the Select
Committee on Intelligence for more than eight years of continuous
service, exclusive of service during the 94th Congress. To the
greatest extent practicable, one-third of the Senators appointed to the
Select Committee at the beginning of the 97th Congress and each
Congress thereafter shall be Senators who did not serve on the Select
Committee during the preceding Congress.16
(4) Intelligence Committee Exception: Mandatory service on the
Select Committee on Intelligence by the Senate majority and minority
leaders is not considered a class B assignment.17
(5) Joint Committees: A member of the Rules and Administration
Committee may not serve on any joint committee. (Members of the
Rules and Administration Committee may not serve on any joint

in order to assure majority party control of all Senate committees applies only to class A
committees, not to class B committees. See Rule XXV, par. 4(c). Note, further, that the rules
do not prohibit class B committee assignments for Senators who serve on three class A
committees because of previous assignments to certain combinations of two or three class A
committees.

18 Rule XXV, par. 4(f).
19 The Select Committee on Indian Affairs, previously scheduled to expire at the end of
the 95th Congress, was extended until the end of the 96th Congress by S.Res. 405 (95th Cong.,
10/14/78), and until 1984 by S.Res. 448, (96th Cong., 12/11/80). By S.Res. 127 (98th Cong.,
6/6/84), the committee was made permanent. Size has been determined pursuant to S.Res.
88 (99th Cong., 3/5/85); S.Res. 14 (100th Cong., 1/6/87); S.Res. 100 (101st Cong., 4/11/89);

20 On October 31, 1979, the Senate agreed to S.Res. 271 (96th Cong.; see Congressional
Record (daily ed.), Oct. 31, 1979, S15485-6), which removed the membership restrictions on
the Select Committee on Ethics previously imposed by S.Res. 338 (88th Cong., 7/24/64, sec.
1(d), as amended by S.Res. 4 (95th Cong., 2/4/77), sec. 102. These restrictions required that
each party assign one member to the select committee who had served in the Senate less than
six years, one who had served between six and 12 years, and one who had served more than
12 years. These restrictions also required that no Senator could serve on the select committee
for more than six continuous years.

II. Subcommittee Assignments
The rules of the Senate define subcommittees as follows: “No committee of the
Senate may establish any subunit of that committee other than a subcommittee, unless
the Senate by resolution has given permission therefor. For purposes of this
subparagraph, any subunit of a joint committee shall be treated as a subcommittee.”24
A.
Class A: A Senator may not serve on more than three subcommittees of any
class A committee except:25
1.
A Senator may serve on any number of subcommittees on the Committee
on Appropriations.26
2.
A Senator may serve ex officio, without vote, on any number of
subcommittees on a committee of which he or she is chair or ranking
minority member.27

III. Full Committee Chairmanships
A.
Basic Limitation: A Senator may not serve as chair of more than one committee
(standing, select, special, or joint) except:31
1.
Joint Committees: A Senator who serves as chair of a standing committee
may also chair a joint committee, the jurisdiction of which is directly related
to that of the standing committee.32
2.
Certain Select Committees: The Select Committee on Ethics and the Select
Committee on Indian Affairs are exempt from this limitation. Thus a
Senator may chair another committee in addition to chairing one, or
theoretically both, of these select committees.33
B.
Republican Term Limits: A Senator shall not serve more than six years as chair
and six years as ranking member of any standing committee, effective in January
1997.34

30 Senate rules imposed no limit on the number of subcommittee assignments that
Senators are permitted on class C committees. The number of subcommittees a class C
committee may create is indirectly limited, however, by the subcommittee chairmanship
limitation. That is, the rule limits the number of subcommittees a committee may create to
the number of majority party Senators on the committees, assuming minority party Senators
do not serve as subcommittee chairs. (See Rule XXV, par. 4(a) and (b)).

IV. Subcommittee Chairmanships
A.
Basic Limitation: A Senator may not chair more than one subcommittee on any
single committee (standing, select, special or joint) of which he or she is a
member.36
B.
Additional Limitations on Committee Chairs:
1.
Class A Committee Chairmen: A class A committee chair may not chair
more than one subcommittee of all the subcommittees on his or her class
A committees. That is, the Senator may chair a subcommittee on only one
of his or her class A assignments. Furthermore, the Senator may not chair
more than one subcommittee on each of his or her class B committees.37
2.
Class B Committee Chairs: A class B committee chairman may not chair
any subcommittee on his or her class B committee—presumably the
Senator’s only class B assignment. Furthermore, the Senator may not chair
more than one subcommittee on each of his or her class A committees.38
C.
Republican Limitations:
1)
A Senator shall not serve as chair or ranking member of a standing
committee other than Rules and Administration and as a chair or ranking
member of another standing committee or subcommittee. Appropriations
subcommittee assignments are exempt.39
35 Ibid.
36 Rule XXV, par. 4(e)(2). In effect, his rule limits the number of subcommittees a
committee may create to the number of majority-party Senators on the committee, assuming
minority party Senators do not serve as subcommittee chairs.
37 Rule XXV, par. 4(e)(3). Since par. 4(e)(2) limits all Senators to no more than one
subcommittee chairmanship on any of their committees, the proviso in the first sentence of
par. 4(e)(3) that chairs of class A committees may chair only one subcommittee on each of
their class B assignments appears to be redundant.
38 Rule XXV, par. 4(e)(3). Since par. 4(e)(2) limits all Senators to no more than one
subcommittee chairmanship on any of their committees, the proviso in the second sentence of
par. 4(e)(3) that chairmen of class B committees may chair only one subcommittee on each
of their class A assignments appears to be redundant.

Library of Congress, charged with providing the United States Congress non-partisan advice on
issues that may come before Congress.
EveryCRSReport.com republishes CRS reports that are available to al Congressional staff. The
reports are not classified, and Members of Congress routinely make individual reports available to
the public.
Prior to our republication, we redacted names, phone numbers and email addresses of analysts
who produced the reports. We also added this page to the report. We have not intentional y made
any other changes to any report published on EveryCRSReport.com.
