Article I, Section 6, 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.
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.1 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 16892 and the history of which traces back almost to the beginning of the development of Parliament as an independent force.3
In the American governmental structure the clause serves the additional function of reinforcing the separation of powers so deliberately established by the Founders.4
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.5
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.’6 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.7 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.8 Immunity from civil suit, 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,9 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,10 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 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.11 And in Dombrowski v. Eastland,12 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 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.13 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.14
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.15 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.16 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.17
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,18 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.19
However, in United States v. Brewster,20 while continuing to assert that the clause
must be read broadly to effectuate its purpose of protecting the independence of the Legislative branch,21 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 performance of such acts and a 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.22 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.23
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,24 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.25
Until recently, the Court distinguished between Members of Congress, who were immune from suit arising out of their legislative activities, and legislative employees who participate in the same activities under the direction of a Member.26 Thus, in Kilbourn v. Thompson,27 the sergeant at arms of the House was held liable for false imprisonment because he executed the resolution ordering Kilbourn arrested and imprisoned. Dombrowski v. Eastland28 held that a subcommittee counsel might be liable in damages for actions as to which the chairman of the committee was immune from suit. And, in Powell v. McCormack,29 the Court held that the presence of House of Representative employees as defendants in a suit for declaratory judgment gave the federal courts jurisdiction to review the propriety of the plaintiff's exclusion from office by vote of the House.
Upon full consideration of the question, however, the Court, in Gravel v. United States,30 accepted a series of contentions urged upon it not only by the individual Senator but by the Senate itself appearing by counsel as amicus:
that it is literally impossible, in view of the complexities of the modern legislative process, with Congress almost constantly in session and matters of legislative concern constantly proliferating, for Members of Congress to perform their legislative tasks without the help of aides and assistants; that the day-to-day work of such aides is so critical to the Members’ performance that they must be treated as the latter's alter ego; and that if they are not so recognized, the central role of the Speech or Debate Clause . . . will inevitably be diminished and frustrated.31 Therefore, the Court held
that the Speech or Debate Clause applies not only to a Member but also to his aides insofar as the conduct of the latter would be a protected legislative act if performed by the Member himself.32
The Gravel holding, however, does not so much extend congressional immunity to employees as it narrows the actual immunity available to both aides and Members in some important respects. Thus, the Court said, the legislators in Kilbourn were immune because adoption of the resolution was clearly a legislative act but the execution of the resolution—the arrest and detention—was not a legislative act immune from liability, so that the House officer was in fact liable as would have been any Member who had executed it.33 Dombrowski was interpreted as having held that no evidence implicated the Senator involved, whereas the committee counsel had been accused of
conspiring to violate the constitutional rights of private parties. Unlawful conduct of this kind the Speech or Debate Clause simply did not immunize.34 And Powell was interpreted as simply holding that voting to exclude plaintiff, which was all the House defendants had done, was a legislative act immune from Member liability but not from judicial inquiry.
None of these three cases adopted the simple proposition that immunity was unavailable to House or committee employees because they were not Representatives or Senators; rather, immunity was unavailable because they engaged in illegal conduct that was not entitled to Speech or Debate Clause protection. . . . [N]o prior case has held that Members of Congress would be immune if they executed an invalid resolution by themselves carrying out an illegal arrest, or if, in order to secure information for a hearing, themselves seized the property or invaded the privacy of a citizen. Neither they nor their aides should be immune from liability or questioning in such circumstances.35
