Learning in the fall of 1977 of possible violations of federal law, the federal grand jury in the District of Rhode Island began an investigation into the activities of particular state officials and private individuals. On February 3, 1978, the United States Attorney petitioned the district court for an order authorizing disclosure оf grand jury materials to an attorney with the Securities Exchange Commission, the attorney general of Rhode Island, and a Rhode Island detective involved in the state investigation of the same charges. The district court entered an order the same day denying disclosure to the Rhode Island attorney general and detective and limited the use of the information disclosed to the SEC attorney to investigation of federal crimes. The United States appeals from so much of the order as denies disclosure to the detective. 1
Because the investigation is continuing, certain details remain confidential. In its motion to the district court, the United States alleged, in essence, that the misconduct under investigation involved violations of both federal and state law, and that an insufficient number of federal investigatory personnel were available to help the grand jury gather necessary information. The detective who had been looking into the matter with respect to state law violations, and had been cooperating with federal investigators, testified before the grand jury on December 8,1977. A week later, the grand jury after secret deliberations reported that it wished to appoint the detective as its agent and to give him access to its materials. The United States subsequently made an ex parte motion to this effect.
The district court, although expressing sympathy for the Federal Government’s manpower problems, felt itself constrained by Fed.R.Crim.P. 6(e) from аuthorizing the disclosure requested.

The court stated
*15
that the Government had not “shown with particularity” the “compelling necessity” for disclosure that is the prerequisite to a court order under paragraph 6(3)(2)(C)(i) of the Rule, citing
United States v. Procter & Gamble Co.,
On appeal, the Government argues that the district court misintеrpreted Rule 6(e), applying too high a standard as to the showing the Government must present to obtain disclosure. It argues that the detective was “government personnel” on these facts, that disclosure to aid the present grand jury proceedings is appropriate under Rule 6(e)(2)(C)(i), and that the showing of need made here was compelling enough to require disclosure. Counsel in opposition refers to substantial legislative history and the definition of “Attorney for the government” in Fed.R.Crim.P. 54(c) 3 as conclusive that Congress in Rule 6(e)(2)(A)(ii) meant to refer only to federal government personnel, and argues that there is no way the state detective can come within the limitation. Counsel would also have us sustain the district court’s refusal to order disclosure under Rule 6(e)(2)(C)(i). He points to the ongoing nature of the grand jury investigation, the difficulty of controlling the uses to which the information might be put by the detective in light of his duties under state law, the insubstantiality of the need asserted, the lack of any justification for disclos *16 ing all grand jury materials to the detective, and the fact that the motion was ex parte, as factors militating against granting the order here.
At the outset the question of appellate jurisdiction must be confronted. The United States has not sought an extraordinary writ under 28 U.S.C. § 1651 or certification of the question under 28 U.S.C. § 1292(b). Our jurisdiction, if it exists, must rest on 28 U.S.C. § 1291, which requires the existence of a “final order” of the district court as the. subject of the appeal.
The United States argues that the motion for disclosure constituted an independent plenary proceeding, and that the district court’s order constituted a final judgment as to that proceeding. In support of this contention it cites cases recognizing the appealability of orders denying applications for electronic surveillance,
In re Application of the United States,
The instant order seems most analogous to rulings on discovery issued during a lawsuit. Such rulings are commonly regarded аs being interlocutory rather than final for purposes of § 1291.
See, e. g., In re United States,
The Government contends that even if the district court’s order is not final for purposes of § 1291, it fits within the “collateral order” exception to the finality rеquirement recognized in
Cohen v. Beneficial Industrial Loan Corp.,
“ ‘(1) the order must be a final determination of a claim of right “separable from, and collateral to,” rights asserted in the action; (2) it must be “too important to be denied review,” in the sense that it “presеnts a serious and unsettled question”; and (3) its review cannot, in the nature of the question it presents, await final judgment because “when that time comes, it will be too late effectively to review the . . . order and rights conferred . . . will have been lost, probably irreparably.” ’ ”
Grinnell Corp., supra,
As for part three of the
Cohen
rule — the need to permit an appeal now to avoid an irretrievable loss of rights — the Government has several alternative means at its disposal to preserve the disclosure right at issue here. First, and most simply, it сould seek a redetermination of the matter by the district court based on a stronger showing of need than it has yet presented. In addition, the Government could either have sought the cooperation of the district court in certifying this question under § 1292(b), or if it felt that circumstances warranted, go into contempt in order to obtain appellate review. We recognize that because the Government is the party seeking review, the contempt alternative is even less attractive here than it was in
Grinnell Corp., supra
at 598.

The United States Attorney has an especially high duty to show respect for an оbedience to the orders of the federal courts. Still the option cannot altogether be ignored. Moreover, the obvious difficulties associated with contempt where the Government is the aggrieved party would doubtless be a factor that might induce this court, in a suitable case, tо look with greater favor on supervisory mandamus, which is a third avenue for obtaining review in circumstances where it is manifestly impor
*18
tant that review be obtained. Were a district court clearly to misinterpret the limitations of Rule 6(e) or plainly abuse its discretion thereunder either in ordering or denying disclosure (a showing that manifestly cannot be made in this case), mandamus is likely to lie.
See, e. g., In re United States,
Appeal dismissed.
Notes
. Because this appeal, as the proceedings below, have been ex parte, this court appointed Professor John Leubsdorf of Boston University School of Law as friend of court to presеnt the case in opposition to the United States. Professor Leubsdorfs brief and oral argument, complementing the Government’s presentation, have been of substantial assistance.
. The Rule provides:
“(e) Secrecy of Proceedings and Disclosure.
(1) General Rule. A grand juror, an interpreter, a stenographer, an operator of a recording device, a typist who transcribes recorded testimony, an attorney for the Government, or any person to whom disclosure is made under paragraph (2)(A)(ii) of *15 this subdivision shall not disclose matters occurring before the grand jury, except as otherwise provided for in these rules. No obligation of sеcrecy may be imposed on any person except in accordance with this rule. A knowing violation of rule 6 may be punished as a contempt of court.
(2) Exceptions.
(A) Disclosure otherwise prohibited by this rule of matters occurring before the grand jury, other than its deliberations and the vote of any grаnd juror, may be made to—
(i) an attorney for the government for use in the performance of such attorney’s duty; and
(ii) such government personnel as are deemed necessary by an attorney for the government to assist an attorney for the government in the performance of such attоrney’s duty to enforce Federal criminal law.
(B) Any person to whom matters are disclosed under subparagraph (A)(ii) of this paragraph shall not utilize that grand jury material for any purpose other than assisting the attorney for the government in the performance of such attorney’s duty to enforce Federal criminal law. An attorney for the government shall promptly provide the district court, before which was impaneled the grand jury whose material has been so disclosed, with the names of the persons to whom such disclosure has been made.
(C) Disclosure otherwise prohibited by this rule оf matters occurring before the grand jury may also be made— •
(i) when so directed by a court preliminarily to or in connection with a judicial proceeding; or
(ii) when permitted by a court at the request of the defendant, upon a showing that grounds may exist for a motion to dismiss the indictment because of matters occurring before the grand jury.
(3) Sealed indictments. The Federal magistrate to whom an indictment is returned may direct that the indictment be kept secret until the defendant is in custody or has been released pending trial. Thereupon the clerk shall seal the indictment and no person shall disclose the return of the indictment except when necessary for the issuance and execution of a warrant or summons.
. “Attorney for the government” is defined to mean “the Attorney General, an authorized assistant of the Attorney General, a United States Attorney, an authorized assistant of а United States Attorney . . . ”
. Arguably the concerns that militate against interlocutory review of judicial orders arising from ongoing grand jury proceedings — particularly the recognition that “encouragement of delay is fatal to the vindication of the criminal law,”
