Article I, Section 6: Congressional Pay and Privileges

Article I, Section 6 of the U.S. Constitution does three important things: It lays out how members of Congress should be paid (which was later modified by the Twenty-Seventh Amendment), protects legislators from lawsuits stemming from their work in Congress, and ensures separation of power by preventing legislators from holding more than one government office. And as with all constitutional provisions, the Supreme Court has had to interpret the words of Article I, Section 6 to determine what they mean for modern legislators.

What Does Article I, Section 6 Say?

Clause 1:

"The Senators and Representatives shall receive a Compensation for their Services, to be ascertained by Law, and paid out of the Treasury of the United States. They shall in all Cases, except Treason, Felony and Breach of the Peace, be privileged from Arrest during their Attendance at the Session of their respective Houses, and in going to and returning from the same; and for any Speech or Debate in either House, they shall not be questioned in any other Place."

Clause 2:

"No Senator or Representative shall, during the Time for which he was elected, be appointed to any civil Office under the Authority of the United States, which shall have been created, or the Emoluments whereof shall have been encreased during such time; and no Person holding any Office under the United States, shall be a Member of either House during his Continuance in Office."

What Does the Constitution Say About How Congress Gets Paid?

United States Library of Congress, The Constitution of the United States of America: Analysis and Interpretation

With the surprise ratification of the Twenty-Seventh Amendment,1 it is now the rule that congressional legislation “varying"—decreasing or increasing—the level of legislators' pay may not take effect until an intervening election has occurred. The only real controversy likely to arise in the interpretation of the new rule is whether pay increases that result from automatic alterations in pay are subject to the same requirement or whether it is only the initial enactment of the automatic device that is covered. That is, from the founding to 1967, congressional pay was determined directly by Congress in specific legislation setting specific rates of pay. In 1967, a law was passed that created a quadrennial commission with the responsibility to propose to the President salary levels for top officials of the government, including Members of Congress.2 In 1975, Congress legislated to bring members of Congress within a separate commission system authorizing the President to recommend annual increases for civil servants to maintain pay comparability with private-sector employees.3 These devices were attacked by dissenting members of Congress as violating the mandate of clause 1 that compensation be “ascertained by Law". However, these challenges were rejected.4 Thereafter, prior to ratification of the Amendment, Congress, in the Ethics Reform Act of 1989,5 altered both the pay-increase and the cost-of-living-increase provisions of law, making quadrennial pay increases effective only after an intervening congressional election and making cost-of-living increases dependent upon a specific congressional vote. A federal court of appeals panel ruled that the cost-of-living-increase provision did not violate the Twenty-Seventh Amendment, and that a challenge to the quadrennial pay raise provision was not ripe.6

What Does "Privilege from Arrest" Mean in Article I?

This clause is practically obsolete. It applies only to arrests in civil suits, which were still common in this country at the time the Constitution was adopted.7 It does not apply to the service of process in either civil8 or criminal cases.9 Nor does it apply to arrest in any criminal case. The phrase “treason, felony or breach of the peace" is interpreted to withdraw all criminal offenses from the operation of the privilege.10

Congressional Speech and Debate Privileges

This clause represents “the culmination of a long struggle for parliamentary supremacy. Behind these simple phrases lies a history of conflict between the Commons and the Tudor and Stuart monarchs during which successive monarchs utilized the criminal and civil law to suppress and intimidate critical legislators. Since the Glorious Revolution in Britain, and throughout United States history, the privilege has been recognized as an important protection of the independence and integrity of the legislature."11 So Justice Harlan explained the significance of the Speech or Debate Clause, the ancestry of which traces back to a clause in the English Bill of Rights of 168912 and the history of which traces back almost to the beginning of the development of Parliament as an independent force.13 “In the American governmental structure the clause serves the additional function of reinforcing the separation of powers so deliberately established by the Founders."14 “The immunities of the Speech or Debate Clause were not written into the Constitution simply for the personal or private benefit of members of Congress, but to protect the integrity of the legislative process by insuring the independence of individual legislators."15

Privilege Extends to Legislative Activity

The protection of this clause is not limited to words spoken in debate. “Committee reports, resolutions, and the act of voting are equally covered, as are `things generally done in a session of the House by one of its members in relation to the business before it.'"16 Thus, so long as legislators are 'acting in the sphere of legitimate legislative activity", they are “protected not only from the consequence of litigation's results but also from the burden of defending themselves." 17 But the scope of the meaning of “legislative activity" has its limits. “The heart of the clause is speech or debate in either House, and insofar as the clause is construed to reach other matters, they must be an integral part of the deliberative and communicative processes by which Members participate in committee and House proceedings with respect to the consideration and passage or rejection of proposed legislation or with respect to other matters which the Constitution places within the jurisdiction of either House."18 Immunity from civil suits, both in law and equity, and from criminal action based on the performance of legislative duties flows from a determination that a challenged act is within the definition of legislative activity, but the Court in the more recent cases appears to have narrowed the concept somewhat.

In Kilbourn v. Thompson,19 Members of the House of Representatives were held immune in a suit for false imprisonment brought about by a vote of the Members on a resolution charging contempt of one of its committees and under which the plaintiff was arrested and detained, even though the Court found that the contempt was wrongly voted. Kilbourn was relied on in Powell v. McCormack,20 in which the plaintiff was not allowed to maintain an action for declaratory judgment against certain Members of the House of Representatives to challenge his exclusion by a vote of the entire House. Because the power of inquiry is so vital to the performance of the legislative function, the Court held that the clause precluded suit against the Chairman and Members of a Senate subcommittee and staff personnel, to enjoin enforcement of a subpoena directed to a third party, a bank, to obtain the financial records of the suing organization. The investigation was a proper exercise of Congress's power of inquiry, the subpoena was a legitimate part of the inquiry, and the clause, therefore, was an absolute bar to judicial review of the subcommittee's actions prior to the possible institution of contempt actions in the courts.21 And in Dombrowski v. Eastland,22 the Court affirmed the dismissal of an action against the chairman of a Senate committee brought on allegations that he wrongfully conspired with state officials to violate the civil rights of the plaintiff.

Through an inquiry into the nature of the “legislative acts" performed by Members and staff, the Court held that the clause did not defeat a suit to enjoin the public dissemination of legislative materials outside the halls of Congress.23 A committee had conducted an authorized investigation into conditions in the schools of the District of Columbia and had issued a report that the House of Representatives routinely ordered printed. In the report, named students were dealt with in an allegedly defamatory manner, and their parents sued various committee Members and staff and other personnel, including the Superintendent of Documents and the Public Printer, seeking to restrain further publication, dissemination, and distribution of the report until the objectionable material was deleted and also seeking damages. The Court held that the Members of Congress and the staff employees had been properly dismissed from the suit, inasmuch as their actions—conducting the hearings, preparing the report, and authorizing its publication—were protected by the clause. 

The Superintendent of Documents and the Public Printer were held, however, to have been properly named, because, as congressional employees, they had no broader immunity than Members of Congress would have. At this point, the Court distinguished between those legislative acts, such as voting, speaking on the floor or in committee, issuing reports, which are within the protection of the clause, and those acts which enjoy no such protection. Public dissemination of materials outside the halls of Congress is not protected, the Court held, because it is unnecessary to the performance of official legislative actions. Dissemination of the report within the body was protected, whereas dissemination in normal channels outside it was not.24

Bifurcation of the legislative process in this way resulted in holding unprotected the republication by a Member of allegedly defamatory remarks outside the legislative body, here through newsletters and press releases.25 The clause protects more than speech or debate in either House, the Court affirmed, but in order for the other matters to be covered “they must be an integral part of the deliberative and communicative processes by which Members participate in committee and House proceedings with respect to the consideration and passage or rejection of proposed legislation or with respect to other matters which the Constitution places within the jurisdiction of either House."26 Press releases and newsletters are “[v]aluable and desirable" in “inform[ing] the public and other Members", but neither are essential to the deliberations of the legislative body nor part of the deliberative process.27

Privilege and Criminal Activity

Parallel developments may be discerned with respect to the application of a general criminal statute to call into question the legislative conduct and motivation of a Member. Thus, in United States v. Johnson,28 the Court voided the conviction of a Member for conspiracy to impair lawful governmental functions, in the course of seeking to divert a governmental inquiry into alleged wrongdoing, by accepting a bribe to make a speech on the floor of the House of Representatives. The speech was charged as part of the conspiracy and extensive evidence concerning it was introduced at a trial. It was this examination into the context of the speech—its authorship, motivation, and content—that the Court found foreclosed by the Speech or Debate Clause.29

However, in United States v. Brewster,30 while continuing to assert that the clause “must be read broadly to effectuate its purpose of protecting the independence of the Legislative branch,"31 the Court substantially reduced the scope of the coverage of the clause. In upholding the validity of an indictment of a Member, which charged that he accepted a bribe to be “influenced in his performance of official acts in respect to his action, vote, and decision" on legislation, the Court drew a distinction between a prosecution that caused an inquiry into legislative acts or the motivation for the performance of such acts and prosecution for taking or agreeing to take money for a promise to act in a certain way. The former is proscribed, the latter is not.

“Taking a bribe is, obviously, no part of the legislative process or function; it is not a legislative act. It is not, by any conceivable interpretation, an act performed as a part of or even incidental to the role of a legislator. . . . Nor is inquiry into a legislative act or the motivation for a legislative act necessary to a prosecution under this statute or this indictment. When a bribe is taken, it does not matter whether the promise for which the bribe was given was for the performance of a legislative act as here or, as in Johnson, for use of a Congressman's influence with the Executive Branch."32

In other words, it is the fact of having taken a bribe, not the act the bribe is intended to influence, which is the subject of the prosecution, and the Speech or Debate Clause interposes no obstacle to this type of prosecution.33

Applying in the criminal context the distinction developed in the civil cases between protected “legislative activity" and unprotected conduct prior to or subsequent to engaging in “legislative activity", the Court in Gravel v. United States,34 held that a grand jury could validly inquire into the processes by which the Member obtained classified government documents and into the arrangements for subsequent private republication of these documents, since neither action involved protected conduct. “While the Speech or Debate Clause recognizes speech, voting and other legislative acts as exempt from liability that might otherwise attach, it does not privilege either Senator or aide to violate an otherwise valid criminal law in preparing for or implementing legislative acts."35

  18. Gravel v. United States, 408 U.S. 606, 625 (1972). The critical nature of the clause is shown by the holding in Davis v.

Whether the clause would be a shield the Court had no occasion to decide and the case was settled on remand without a decision being reached.

The case also leaves unresolved the propriety of injunctive relief. Compare id. at 330 (Justice Douglas concurring), with id. at 343–45 (three dissenters arguing that separation of powers doctrine forbade injunctive relief). And compare Davis v.

  27. Hutchinson v. Proxmire, 443 U.S. 111, 130, 132–33 (1979). The Court distinguished between the more important informing function of Congress, i.e., its efforts to inform itself in order to exercise its legislative powers, and the less important informing function of acquainting the public about its activities. The latter function the Court did not find an integral part of the legislative process. See also Doe v. McMillan, 412 U.S. 306, 314–17 (1973)But compare id. at 325 (concurring). For consideration of the informing function in its different guises in the context of legislative investigations, see Watkins v. United States, 354 U.S. 178, 200 (1957)United States v.

  29. Reserved was the question whether a prosecution that entailed inquiry into legislative acts or motivation could be founded upon a narrowly drawn statute passed by Congress in the exercise of its legislative power to regulate the conduct of its members. 383 U.S. at 185. The question was similarly reserved in United States v. Brewster, 408 U.S. 501, 529 n.18 (1972), although Justices Brennan and Douglas would have answered in the negative. Id. at 529, 540.

  32. 408 U.S. at 526.
  33. The holding was reaffirmed in United States v. Helstoski, 442 U.S. 477 (1979). On the other hand, the Court did hold that the protection of the clause is so fundamental that, assuming a Member may waive it, a waiver could be found only after explicit and unequivocal renunciation, rather than by failure to assert it at any particular point. Similarly, Helstoski v. Meanor, 442 U.S. 500 (1979), held that since the clause properly applied is intended to protect a Member from even having to defend himself, he may appeal immediately from a judicial ruling of nonapplicability rather than wait to appeal after conviction.
