Supplemental Opinion for the Court filed by Circuit Judge GINSBURG.
GINSBURG, Circuit Judge:
This case was argued on March 17, 1995, and decided in an opinion issued on July 18, 1995. United States v. Rostenkowski, 59 F.3d 1291 (D.C.Cir.1995). Between those two dates, the Supreme Court decided Hubbard v. United States, — U.S. -, 115 S.Ct. 1754, 131 L.Ed.2d 779 (1995), in which it concluded that the Congress is not a "department or agency of the United States" within the meaning of 18 U.S.C. § 1001, which prohibits making a false or misleading statement to any such entity. In six counts of the indictment brought against Rostenkowski it is alleged that he violated § 1001 when he made certain statements either to the House Disbursing Office or to the Federal Election Commission. In order to avoid prematurely reaching Rostenkowski's challenge to the constitutionality of § 1001 as applied to a Member of Congress, we remanded those six counts to the district court to determine in the first instance whether any of them survives. Hubbard. 59 F.3d at 1302.
The Government now petitions for rehearing, urging the court, among other things, to reconsider the import of Hubbard and to address the constitutional issues that Rostenkowski raises relating to § 1001. According to the Government, we would thereby -conserve judicial resources and potentially avoid the delay that would result if Rostenkowski were to file another interlocutory appeal after the district court rales upon these issues. We decline the Government's invitation to reach these issues on the present appeal.
In United States v. Bramblett, 348 U.S. 503, 75 S.Ct. 504, 99 L.Ed. 594 (1955), the Supreme Court had held that the term "department" as used in § 1001 refers to all three branches of Government. In Hubbard the Court overruled Bramblett to hold that the term "department" refers only to a "component of the Executive Branch." — U.S. at -, 115 S.Ct. at 1757-59. With respect to the term "agency" in § 1001, upon which Bramblett was silent, the Supreme Court held in Hubbard only that a court is not an "agency," id. at -, 115 S.Ct. at 1757; it "express[ed] no opinion as to whether any other entity within the Judicial Branch might be an 'agency,' " id. at -, 115 S.Ct. at 1758 n. 3. By parity of reasoning, it would seem that the Congress is not an "agency" as that term is used in § 1001. See id. at -, 115 S.Ct. at 1761 ("it would be curious indeed if Congress truly intended [§ 1001] to work a dramatic alteration in the law governing misconduct in the court system or the Legislature"). Still, the Supreme Court withheld judgment upon the question whether any other entity within the Legislative Branch might be an "agency"; indeed, the Court remarked that the House Disbursing Office, one of the entities involved in this case, "arguably [is] an agency within the meaning of § 1001." Id. at - n. 5, 115 S.Ct. at 1759 n. 5.
Thus the status of the House Disbursing Office remains unresolved. The Supreme Court reserved the question in Hubbard, as did we in Bostenkowski. Nevertheless the Government now suggests that the district court is precluded from holding on remand that the House Disbursing Office is an agency for the purpose of § 1001 because in United States v. Dean, 55 F.3d 640, 659 (D.C.Cir.1995), we stated that Hubbard "narrowed the reach of § 1001 to matters within the Executive Branch, a coverage consistent with both the common usage of 'department' and that term's definition in Title 18." That is an overreading of Dean. As the last-quoted clause indicates, we stated in Dean only that Hubbard controls our interpretation of § 1001 with respect to the question of what is a "department" of the United States. We had no occasion in Dean to interpret the term "agency" — the indictment alleged that Dean had made false statements to a "department of the United States," viz. the Senate Banking Committee — and we did not do so.
The Government errs also in suggesting that it would serve judicial economy for this court to determine in the first instance whether the House Disbursing Office is an agency within the meaning of § 1001. That question has never been briefed or argued in this court. As the Government well knows, however, it was fully briefed and submitted to the district court before the Government filed the present petition for rehearing. Moreover, while the issue is ultimately one of statutory construction, it would not be surprising if the court found it necessary penultimately to resolve factual issues. See Armstrong v. Executive Office of the President, 1 F.3d 1274, 1290, 1295 (D.C.Cir.1993) (holding entity that functions solely to advise and assist President is not an agency under the Freedom of Information Act, and remanding case for district court to develop facts necessary to determine whether National Security Council is such an entity). Therefore, contrary to the Government's claim, there is little reason to think that we could economize on judicial resources by resolving the question whether the House Disbursing Office is an "agency" within the meaning of § 1001 before the district court has passed upon that question.
The Government raises various other arguments for rehearing, none of which warrants treatment in a published opinion. Accordingly, the petition for rehearing is
Denied.
