Mr. Justice Harlan
delivered the opinion of the • Court.
This is a companion case to Barr v. Matteo, ante, p. 564, decided today. Petitioner Howard in 1955 was a Captain in the United States Navy and Commander of the Boston Naval Shipyard. Respondent Lyons was National Commander of the Federal Employees Veterans Association, Inc., and respondent McAteer a local officer of that Association. Both respondents, were at all material times civilian employees at the Boston Naval Shipyard, and for several years before September 8, 1955, the Association was recognized by the shipyard as an employees’ representative group. On that date petitioner withdrew official recognition of the- Association — an action which is not here challenged. '
Respondents brought suit in the Massachusetts District Court, -invoking .diversity jurisdiction, and making the following, allegations: that on September 8, 1955, petitioner. circulated a statement defaming them; that the statement purported to be an official memorandum to the Chief of the Bureau of Ships and the Chief of Navy Industrial Relations, but was released by petitioner “outside of his official duties” to various newspapers and wire services and to the. members of the Massachusetts delegation in the Congress of'the'United States; that in circulating the statement petitioner acted “maliciously, wilfully, wickedly, recklessly and. falsely and with malice aforesight [sic]”; and thát the statement .was intended to and did injure the reputation of respondents.
' A copy of the statement complained of was filed with the complaint. It is in the form of an official report directed tó the Chief of the Bureau of Ships and the Chief of Industrial Relations of the Department of . the Navy, reciting petitioner’s dissatisfaction with the activities of the Federal Employees Veterans Association at the shipyard and announcing his intention to withdraw the recognition previously accorded it.
Petitioner answered, stating that the statement complained of was in fact an official communication, and that in sending copies of it to the Massachusetts congressional delegation he was acting within the scope of his duties and pursuant to Department of the Navy policy; and denying .that outside of his official duties he had released copies of the communication to the newspapers. He thereupon moved for summary judgment, attaching to the motion his own affidavit essentially repeating the statements from his answer above summarized, and an affidavit from the Commandant of the First Naval District. That affidavit stated that the Commandant was petitioner’s commanding officer; that the making of reports to the Bureau of Ships relative to any significant personnel action at the shipyard was one of petitioner’s official duties; that also among those duties was the furnishing of copies of such reports to the Massachusetts congressional delegation; and that the dissemination of the report of September 8,. 1955, to the newspapers had been made through official channels and approved by the acting Commandant of the First Naval District.
The District Court granted summary judgment for petitioner, holding that the uncontradicted affidavits conclusively showed that the statement complained of was published by petitioner “in the discharge of his official duties and in relation to matters committed to him for determination,” and that it was therefore absolutely privileged. On respondents’ appeal, the Court of Appeals held that the sending of the official report to petitioner’s superior officers was protected by an absolute privilege, and noted that reliance on the dissemination to the newspapers had been abandoned by respondents on appeal in the face of petitioner’s sworn' statement that he had hot been responsible for that publication. As to the publication to the Massachusetts congressional delegation, however, the court, one judge dissenting, refused to allow more than a qualified privilege, although recognizing that “it is true that these mémbers of Congress-did have an official interest in being kept advised of important developments in labor relations at the ■ Boston Naval Shipyard,” and that “the Commander of the Boston Naval Shipyard might have conceived it to be a proper exercise of his official functions to see to it that the members of Congress should receive copies of such official report . . . .” Accordingly, it reversed the judgment of the District* Court and remanded the case -for "trial. • 250 F. 2d 912.
We granted, certiorari to consider petitioner’s contention that the Court of Appeals had erred in failing to recognize his plea of absolute privilege in respect of the publication to members of Congress. 357 U. S. 903. Respondents did not cross-petition for certiorari.
At the outset, we take note of a question which the Court of Appeals, on its view of the case, did not find i.t necessary to resolve — whether the extent of the privilege in respect of civil liability for statements allegedly defamatory under state law which may be claimed by officers of the Federal Government, acting in the course of their duties, is a question as to which the federal courts. are bound to follow state law. We think that the very statement of the question dictates a negative answer.. The authority of a federal officer to act derives from federal sources, and the rule which recognizes a privilege finder appropriate circumstances as to statements made in the course of duty is one designed to promote the effective functioning of the Federal Government. No subject could be one of more peculiarly federal concern, and it would deny the very considerations which give the rule of privilege its being to leave determination of its extent to the vagaries of the laws of the several States. Cf. Clearfield Trust Co. v. United States, 318 U. S. 363. We hold that the validity of petitioner’s claim of absolute privilege must be judged by federal standards, to be formulated by the courts in the absence of legislative action by Congress.
Our decision in Barr v. Matteo, ante, p. 564, governs this case. As has been observed, petitioner and his commanding officer both stated in uncontradicted affidavits that the sending of copies of the report here at issue to members of the Massachusetts congressional delegation was part of petitioner’s official duties. Although of course such an averment by the defendant cannot foreclose the courts from examination of the question, we think that the affidavit of petitioner’s commanding officer,- and a Memorandum of Instructions issued by the Secretary of the Navy which petitioner has with our leave filed in this Court, plainly show that the District Court was correct in finding that the circulation of the report to the Massachusetts congressional delegation was “in the discharge of [petitioner’s] . . . official duties and in relation to matters committed to him for determination.”
Reversed.
No purpose would be served by setting out the entire, lengthy report. It is adequately summarized in the Court of Appeals’ opinion as follows:
“This letter alleged that' plaintiff Lyons by name, and the other plaintiff by description, ‘exercise a predominant influence’ in the organizational activities; that the organization has been giving wide distribution to a newsletter or bulletin; that this bulletin has become more and more unfairly .critical of the shipyard administration, for the purpose of not only thwarting the aims of the shipyard administration in the accomplishment of its mission, but also to further personal aims and self-interests of the individuals in control of the labor organization; that these ‘editorial expletives’ have adversely affected the general morale of employees of the shipyard, who are entitled to be protected against such ‘overt subversion’ by any labor group ‘whose methods and whose motives are unethical, uninhibited, and lack the integrity of purpose that could reasonably be expected.’ ” 250 F. 2d 912, 913;
SECNAV Instruction 5730.5, issued February 3, 1955, paragraph 12: “Congressional Notification of Actions of Interest. Members of Congress are very anxious to keep in touch with what is going on in their respective states and districts. Navy agencies shall keep them advised, if possible in advance, of any new actions or curtailment of actions which may affect them.”
