Opinion for the Court filed by Senior District Judge JAMES E. DOYLE with whom Circuit Judge WILKEY concurs.
Dissenting opinion filed by Circuit Judge STARR.
JAMES E. DOYLE, Senior District Judge:Samuel Friedman appeals an order of the United States District Court for the District of Columbia denying his motions to compel the Commodities Future Trading Commission (CFTC) and the Securities and Exchange Commission (SEC) to comply with two related subpoenas. We hold that the district court’s grounds for denying the subpoenas were erroneous, vacate the judgment, and remand for further proceedings.
I.
Friedman was a party to two civil lawsuits arising out of the silver crisis.1 The *1339price of silver futures rose and fell dramatically in 1979-80. SEC investigated this unusual fluctuation and published its findings in October 1982. As the agency primarily responsible for regulation of the commodity futures market, CFTC initiated its own investigation to determine whether there had been violations of the federal commodities laws. The CFTC investigation is not complete and no report has been published.
On January 26, 1983, a Wednesday, Friedman served a subpoena duces tecum et ad testificandum, issued by the United States District Court for the District of Columbia, on the general counsel of CFTC, requiring appearance on Wednesday, February 2, 1983. The subpoena demanded production of the following documents for inspection and copying:
(a) All transcripts of the testimony which refers or relates to or was given in connection with the investigation of the activity in the silver and silver futures markets in 1979-80 by the Commodity Futures Trading Commission.
(b) All indices of documents produced in connection with the investigation referred to above.
On the same date Friedman served a subpoena duces tecum et ad testificandum, issued by the United States District Court for the District of Columbia, on the Secretary of SEC, also requiring an appearanee on February 2, 1983. The subpoena demanded production of the following documents for inspection and copying:
(a) Transcripts of testimony given by (1) Nelson Bunker Hunt, (2) William Herbert Hunt, (3) Lamar Hunt, (4) James Parker, and (5) Charles Mercer in connection with the investigation of the activity in the silver and silver futures markets in 1979-1980, conducted by the Securities and Exchange Commission (“SEC”) Investigation No. HO-1233.
(b) All indices of documents produced in connection with Investigation No. HO-1233.2
On Monday, January 31, 1983, pursuant to Rule 45(d), Fed.R.Civ.P., the general counsel of CFTC served a notice of objection to the CFTC subpoena on the grounds that:
[T]he [general counsel] to whom the subpoena is directed, does not have custody or control of any documents which could be deemed to be responsive to the instant subpoena ____ Second, ... Section 222(5) of the Futures Trading Act of 19823 ... allows the Commission to disclose information in its possession pursuant to a subpoena, ... only if: (1) a copy of the subpoena ... has been mailed to the last known home or business address of the person who submitted the information that is the subject of the subpoena; and (2) at least fourteen (14) days have *1340expired from the date of such mailing of the subpoena____ Further, ... the subpoena on its face only seeks information which is protected from disclosure by the law enforcement investigatory files privilege ____ Finally, ... Section 8(a) of the Commodity Exchange Act4 ... generally prohibits the Commission from disclosing such confidential information.
On Tuesday, February 1, 1983, pursuant to Rule 45(d), Fed.R.Civ.P., the secretary of SEC served an objection to the subpoena on the ground that the “disclosure of the requested documents ... would interfere with an ongoing investigation being conducted by the Commodities Futures Trading Commission.”
On Wednesday, February 2, 1983, pursuant to Rule, 45, Fed.R.Civ.P., Friedman filed motions in the United States District Court for the District of Columbia to enforce both subpoenas. Accompanying these motions was a request for an expedited briefing schedule (five days) and hearing (the seventh day). The expressed reasons for requesting these accelerated procedures were the imminence of trial set for April 7, 1983, at Bache’s insistence, in Bache’s action against Friedman in the Florida state court and nine depositions scheduled in February 1983, commencing February 9, 1983, in the lawsuit in the Illinois district court.
On Friday, February 4, 1983, the district court heard oral argument on the enforcement motions. The court requested a brief from CFTC by Tuesday, February 8, 1983, “supporting [its] position that [the general counsel] is not the appropriate officer to be subpoenaed, and telling the court why, and secondly, on [its] claim of privilege as being appropriately raised before the court under Black versus Sheraton in this circuit.” (Tr. 26) On February 8, 1983, CFTC submitted its brief. On the same date Friedman submitted a supplemental brief in support of his motion. SEC was not required to, and did not submit a brief.
As of February 9, 1983, the documents described in the subpoenas had not been examined, one by one, by responsible members or officers of CFTC, in response to the subpoenas, to determine whether, in the opinion of CFTC, each particular document is relevant to the subject matter of the Illinois lawsuit or is privileged, within the meaning of Fed.R.Civ.P. 26(b)(1). Counsel for the CFTC represented to the district court that as of February 8, 1983, more than 40 persons had testified in CFTC’s silver investigations, more than 6000 pages of their testimony had been transcribed, the indices of all documents compiled identified over 60,000 pages of documents (located in four cities), and the indices compiled totalled over 1000 pages in length. Also, counsel for CFTC represented, on information provided by SEC counsel, that about 200,000 pages of material had been compiled in SEC’s investigation, the combined length of two sets of indices to these documents was 200 pages and a third set of indices was on tape and untranscribed.
On February 9, 1983, the district court entered its order denying Friedman’s motion to enforce each of the two subpoenas.
II.
The entire operative portion of the order appealed from reads: “[P]laintiff’s motion to compel [is] denied for failure to (1) show *1341the unavailability of the materials from persons or businesses that have an interest or play a role in the underlying civil action, (2) establish that Section 8(a) of the Commodities Exchange Act, as amended, does not bar disclosure of the requested materials in a pending enforcement case, and (3) establish that Section 522(5) [sic] of the Futures Trading Act does not bar enforcement of a subpoena on less than 14 days notice.” We will express below our awareness of the time constraints by which the district court considered itself bound. They explain the brevity of the challenged order. That brevity requires us, however, to exercise a degree of intuition in amplifying the stated grounds, particularly the first. We address the three grounds in sequence.
A. Need: unavailability from alternative sources.
A showing of relevance can be viewed as a showing of need; for the purpose of prosecuting or defending a specific pending civil action, one is presumed to have no need of matter not “relevant to the subject matter involved in the pending action.” Fed.R.Civ.P. 26(b)(1). But it is highly unlikely that relevance was a factor in the district court’s decision. While it is true this or that specific document in the CFTC and SEC silver investigation files may not be relevant to the subject matter of Friedman v. Board of Trade of the City of Chicago, No. 80-C-1111 (N.D.Ill.),5 it seems clear that the bulk of the content of those investigation files is relevant. Neither CFTC nor SEC appears seriously to challenge this proposition.
Of course, the district court was well aware that since the 1970 amendment to Rule 34, a showing of good cause is not a general requirement for the discovery of documents under that rule or, by analogy, under Rule 45. 4A J. Moore, Moore’s Federal Practice § 34.02[2.-2] (2d ed. 1983).
We are confident that the district court’s reference to availability of the materials from alternative sources was made exclusively in the context of the claim of privilege raised by CFTC and SEC.6 There surely is such a thing as a qualified common-law privilege,7 within the meaning of Fed.R.Civ.P. 26(b), for law-enforcement investigatory files. Black v. Sheraton Corp. of America, 564 F.2d 531, 541-542 (D.C.Cir.1977). Also, when the existence of such a conditional privilege is established, there is a need to balance the public interest in nondisclosure against the need of the particular litigant for access to the privileged information. United States v. Reynolds, 345 U.S. 1, 11, 73 S.Ct. 528, 533, 97 L.Ed. 727 (1953); Black v. Sheraton Corp. of America, 564 F.2d at 545-547. Whether the materials are available from other sources is a factor in determining the degree of the litigant’s need to obtain it from the governmental agency or officer claiming the privilege. Finally, it was not clearly erroneous for the district court to conclude that as of February 9, 1983, Friedman had failed to make a strong showing of unavailability from alternative sources.
The major error we perceive in the district court’s order, however, is that the existence of a qualified law-enforcement investigatory files privilege as to all of the subpoenaed documents had not been sufficiently established by CFTC so as to support wholesale and final rejection of Friedman’s motion to compel compliance.
The party claiming privilege has the burden to establish its existence. Black v. Sheraton Corp. of America, 564 F.2d 531, *1342547 (D.C.Cir.1977); see also Robinson v. Magovern, 83 F.R.D. 79 (W.D.Pa.1979). It is doubtful CFTC had met the very threshold requirement of presenting the claim properly. It will not be considered unless presented in a deliberate, considered and reasonably specific manner:
[GJovernmental privilege^] must be formally asserted and delineated in order to be raised properly----
The claiming official must “have seen and considered the contents of the documents and himself have formed the view that on grounds of public interest they ought not to be produced" and state with specificity the rationale of the claimed privilege____
Formally claiming a privilege should involve specifying which documents or class of documents are privileged and for what reasons, especially where the nature of requested documents does not reveal an obviously privileged matter.
Kerr v. United States Dist. Ct. for North. Dist. of Cal., 511 F.2d 192, 198 (9th Cir.1975) (cites omitted) (quoting United States v. Reynolds, 345 U.S. 1, 8 n. 20, 73 S.Ct. 528, 532 n. 20, 97 L.Ed. 727 (1953)). See United States v. Winner, 641 F.2d 825, 831-832 (10th Cir.1981); United States v. O’Neill, 619 F.2d 222, 225-227 (3rd Cir.1980). CFTC had made a generalized claim that the requested documents are protected by a common-law law-enforcement investigatory files privilege.8 CFTC’s attorney in the district court had suggested disclosure would reveal law enforcement techniques and sources: disclose strategy, procedures, and direction of the investigation, forewarn suspects, deter witnesses from providing candid testimony, invite others to seek discovery. However, the files had not been examined for this purpose by responsible members or officers of CFTC. No specific documents or classes of documents had been identified.
Until the claim of privilege has been presented to a district court with appropriate deliberation and precision and the duty of the demanding party to show his or her need for disclosure has thus been triggered,9 and until that duty has then been discharged by the demanding party, the district court is not equipped to engage in the task of identifying and weighing the competing interests. When, as here, the privilege claimed is qualified, not absolute, the process of identification and weighing cannot be avoided. Specifically with respect to the common-law law-enforcement investigatory files privilege, many factors must be addressed. A helpful list appears in Frankenhauser v. Rizzo, 59 F.R.D. 339, 344 (E.D.Pa.1973):
(1) the extent to which disclosure will thwart governmental processes by discouraging citizens from giving the government information; (2) the impact upon persons who have given information of having their identities disclosed; (3) the degree to which governmental self-evaluation and consequent program improvement will be chilled by disclo*1343sure; (4) whether the information sought is factual data or evaluative summary; (5) whether the party seeking discovery is an actual or potential defendant in any criminal proceeding either pending or reasonably likely to follow from the incident in question; (6) whether the police investigation has been completed; (7) whether any intradepartmental disciplinary proceedings have arisen or may arise from the investigation; (8) whether the plaintiffs suit is non-frivolous and brought in good faith; (9) whether the information sought is available through other discovery or from other sources; and (10) the importance of the informa-' tion sought to the plaintiff’s case.
Departure from the well-established sequence of burdens of going forward in qualified privilege disputes is not justified by the fact that the Friedman subpoenas expressly describe their target as law-enforcement investigatory files. There is a considerable variety of law-enforcement investigatory files and there is a considerable variety of information within particular law-enforcement investigatory files. CFTC represented to the district court that much of the content of its silver investigation files is in the public domain, and it suggested that these non-confidential documents would be available to Friedman upon request under the Freedom of Information Act. That the qualified privilege is not claimed as to the entire files only adds to the necessity that the process of adjudication of the privilege begin with a deliberate and reasonably specific delineation of the claim by CFTC.
With the proceeding in its February 9, 1983 posture, decision on the merits on any ground and in either direction was premature, with respect to the claim of a common-law privilege for law-enforcement investigation files.
B. Section 8(a) of the Commodities Exchange Act (CEA)
It would not have been premature to deny Friedman’s motion on its merits on the basis that Section 8(a) of the Act10 flatly bars Friedman from access to the CFTC and SEC silver investigation files. But it would have been erroneous. The district court’s second stated ground for its order was that Friedman had failed to “establish that Section 8(a) ... does not bar disclosure of the requested materials in a pending enforcement case____” We take this to be a holding that Section 8(a) does bar disclosure.
Although Section (8) allows CFTC to “withhold from public disclosure any data or information concerning or obtained in connection with any pending investigation of any person” (7 U.S.C. § 12(a) (Supp.1983)), this protection does not apply to discovery requested pursuant to rules 26 and 45 Fed.R.Civ.P. “[L]imited disclosure in judicial proceedings, carefully curtained by judicious use of protective orders authorized by Rule 30, is not a publishing barred by this section.” Freeman v. Seligson, 405 F.2d 1326, 1348 (D.C.Cir.1968). Freeman arose before an amendment to § 8(a) added a shelter from publication for investigatory information. It addressed statutory language in the original Act protecting business transactions, trade secrets and names of customers. But the same considerations are operative to statutory shields for both types of information.
Freeman stressed the importance of the litigants’ and courts’ access to relevant information, a “foundation for the achievement of justice in individual lawsuits.” Id. Congress must “clearly” and “strongly” indicate its intent to contradict this broad objective favoring disclosure in judicial proceedings.
[I]n other instances where Congress has thought it necessary to protect against court use of records it has expressly so provided by specific language. We see no warrant for inferring that Congress has so elevated the interests] [identified in § 8(a) ] that it gives them dominance over basic rules of judicial administration, especially when it is taken into ac*1344count that courts can and do carefully confine disclosures as narrowly as possible.
Id. at 1351.
Statutes insulating information from publication are aimed at the broadcasting of sensitive information to the general populace; the statutes are not intended to enjoin the limited kind of disclosure encountered in judicial proceedings. The exemptions provided in the Freedom of Information Act (FOIA) are comparable to those in § 8(a) of the CEA in that both offer refuge from publication but not from court-supervised discovery. The relation between discovery procedures and FOIA exemptions is well-established. See, e.g., Verrazzano Trading Corp. v. United States, 349 F.Supp. 1401, 1403 (Cust.Ct.1972). The § 8(a) protections parallel that relationship.
If information in government documents is exempt from disclosure to the general public under FOIA, it does not automatically follow the information is privileged within the meaning of rule 26(b)(1) and thus not discoverable in civil litigation. Firestone Tire & Rubber Co. v. Coleman, 432 F.Supp. 1359 (N.D.Ohio 1976). The FOIA acts as a “floor” when discovery of government documents is sought in the course of civil litigation. Though information available under the FOIA is likely to be available through discovery, information unavailable under the FOIA is not necessarily unavailable through discovery. J. Loran, Information Disclosure in Civil Actions: The Freedom of Information Act and Federal Discovery Rules, 49 Geo.Wash.L.Rev. 843, 849 (1981).
The FOIA furthers the public’s general right to know and ensures government accountability. Discovery discourages unfair surprise and delay at trial. In the FOIA context, the requesting party’s need for the information is irrelevant; the most urgent need will not overcome an applicable FOIA exemption. In the discovery context, when qualified privilege is properly raised, the litigant’s need is a key factor. Whether the information is disclosed depends on the relative weight of the claimant’s need and the government’s interest in confidentiality. Id. at 851-2. It is unsound to equate the FOIA exemptions and similar discovery privileges. We find it equally untenable to equate the § 8(a) protections from publication and similar qualified privileges from discovery.
Nevertheless, statutory publication shelters may have some application to discovery. These protected interests reflect a congressional judgment that certain delineated categories of documents may contain sensitive data which warrants a more considered and cautious treatment. In the context of discovery of government documents in the course of civil litigation, the courts must accord the proper weight to the policies underlying these statutory protections, and to compare them with the factors supporting discovery in a particular lawsuit. Id. at 852-8; see also Black v. Sheraton Corp. of America, 564 F.2d 531, 547 (D.C.Cir.1977).
In camera inspection of allegedly privileged documents and protective orders, when appropriate, are accepted procedures in this circuit, at least where as here military and diplomatic secrets are not at issue. See, e.g., Committee for Nuclear Responsibility, Inc. v. Seaborg, 463 F.2d 788, 794 (D.C.Cir.1971).
The courts can limit, and in actual practice do limit, the persons having access to information, their freedom to discuss the information to which they are given access, and the uses to which the information may be put. No great outcry has arisen that information thus restricted has been leaked, or put to improper uses, by attorneys who are sworn officers of the court.
Freeman, 405 F.2d at 1350. The potential harm to the government is minimal when appropriate precautions are taken. Consequently, statutes prohibiting general publication do not prohibit judicial discovery. We hold § 8(a) of the CEA does not automatically bar disclosure of the requested materials, but that the district court may *1345consider § 8(a) as congressional underscoring of the government’s interest in protecting sensitive investigatory information.
C. Section 222(5) Futures Trading Act (FTA)
The district court held. Friedman had failed to “establish that Section 222(5) of the Futures Trading Act does not bar enforcement of a subpoena on less than 14 days notice.”
Section 222(5) requires CFTC to notify contributors of information in its possession fourteen days prior to disclosure of that information. 7 U.S.C. § 12(f) (Supp.1983). It does not create an absolute statutory privilege or bar enforcement of the subpoena; it only delays disclosure while notification is accomplished.
Friedman contends notification is not required for the SEC documents, which are not in CFTC’s possession. We agree. “The Commission [CFTC] shall disclose information in its possession____” 7 U.S.C. § 12(f) (Supp.1983). The Act specifically does not supersede or limit the jurisdiction conferred on the Securities and Exchange Commission. 7 U.S.C. § 2 (Supp.1983). SEC is not affected by the notification requirements of § 222(5) and CFTC is required to notify only those parties who have contributed information which is presently in CFTC’s possession.
We reject Friedman’s contention that § 222(5) is inapplicable to indices to documents. It is true that CFTC’s indices themselves are not contributed by third parties. They are descriptions of material contributed by others and they reveal those contributors’ identities. Consideration of fairness and of opportunity to assert individual objections to disclosure apply, therefore, to the indices as well as to the underlying documents.11
Contrary to Friedman’s contention, section 222(5) is applicable to this lawsuit, though it did not become effective until January 11, 1983.12 The date of service of the subpoenas, January 26, 1983, is the operative date in the present case.
Upon reviewing Friedman’s requests and CFTC’s privilege claims,'the district court must order CFTC to comply with the requirements of § 222(5) of the Futures Trading Act before disclosing those CFTC documents, if any, ultimately judged relevant and not privileged.
Ill
The district court was confronted by an aggressive litigator who made extreme demands upon the human resources of CFTC, SEC, and the United States District Court for the District of. Columbia.
In this opinion we have remarked upon the brevity of the district court’s order. We could not be more keenly aware of the reasons for that brevity. The conscientious and diligent district judge obviously considered himself bound to decide on the merits, forthwith, Friedman’s motion to compel compliance as Friedman was urging him to do. We surmise that the court’s sense of urgency was less a response to the prompting of an aggressive litigant than to its sense of obligation to the federal court in Illinois and the state court in Florida.
We have remarked upon the inadequacy of the CFTC and SEC claims of privilege as of February 9, 1983, the date of the district court’s decision. We could not be more keenly aware of the reasons for that inadequacy. We have noted CFTC’s explicit representations to the district court that it was prepared to embark upon the task of preparing and presenting to the court a deliberate and reasonably precise invocation of its claim of qualified privilege, but that the task could not be performed overnight, so to speak.
*1346We have remarked as well upon the aggressive posture of movant Friedman in the district court.13 He contended at the time that it was justified on two grounds. One was that in the lawsuit in the federal court in Illinois in which he was plaintiff, he had scheduled depositions only a few days off. The second was the imminence of the April 11, 1983 trial in the Florida state court lawsuit in which he was a defendant. The first justification is unappealing, although it cannot be evaluated properly without considerably more information about the procedural history of the lawsuit in the federal court in Illinois. But the second justification cannot be rejected as readily as it is rejected in the dissenting opinion in this court. CFTC counsel represent to us that some time prior to February 2, 1983, when he filed his motions to compel in the federal district court in the District of Columbia, Friedman had moved to stay the proceedings against him in the Florida state court, and that the stay was granted on March 18, 1983. As of January 26, 1983, through February 9, 1983, Friedman presumably had little control over the rate of progress in the Florida litigation. He would have been open to criticism, perhaps fatal handicaps, if in that case the trial judge had considered Friedman delinquent in seeking discovery of documents needed for his defense. All Friedman could do was seek the CFTC and SEC documents as fast as he could. Had the federal district court for the District of Columbia slowed the pace in the proceeding to enforce the CFTC and SEC subpoenas, Friedman could have informed the Florida court that despite his best efforts, the matter of the discovery of the documents was in the hands of the federal court in the District of Columbia and that their availability or unavailability awaited that court’s ruling.14
It was up to the federal district court in the District of Columbia to determine the time within which CFTC and SEC could reasonably be expected to present properly to the court their claims of privilege, Friedman could be heard in response, and the court could have made the usual amount of inspection of the documents in dispute. Accommodation among courts within the federal judicial system and within the state judicial system and between the two systems requires considerable sensitivity and cooperation. However, each court must insist upon the minimal time necessary to adequate presentation of the issue before .it and to just resolution of the issue. In the present case, the district court did not provide CFTC and SEC sufficient time properly to present the claim of privilege. But it proceeded, on the basis of an inadequate presentation of the claim of privilege, to decide that the claim was valid. This decision on the merits against the movant Friedman was error. We appreciate that there is room for disagreement concerning the degree of justification for appellant Friedman’s aggressiveness in the district court. But even if we were more disapproving of that aggressiveness than we are, we could not agree that the response should take the form of appellate affirmance of an erroneous district court ruling on the law, carefully developed over the years by this and other courts, concerning the threshold requirements for proper presentation of a claim of privilege.
IV.
The order appealed from is reversed and vacated, and the case is remanded for further proceedings consistent with this opinion.
. He is plaintiff in an Illinois action Friedman v. Bache Halsey Stuart Shields, Inc., Bache Group, Inc., Board of Trade of the City of Chicago, Nelson Bunker Hunt, William Herbert Hunt and Lamar Hunt, No. 80-C-1111 (U.S.D.C., N.D.Ill.) to recover a $500,000 loss in 1979 silver futures trading. On February 17, 1983, the defendant Hunt brothers were dismissed by stipulation. On September 6, 1983, defendants Bache Group and Bache Halsey Stuart Shields, Inc. were dismissed. The remaining defendant in the Illinois action is the Chicago Board of Trade *1339(CBOT). The two subpoenas in dispute bore the title of this Illinois action and stated that the depositions were to be taken in this Illinois action.
He was a defendant in a Florida state court action, Bache Halsey Stuart Shields, Inc. v. Samuel Friedman, No. 80-4340(17), Circuit Court of the Eleventh Judicial District of Florida, Dade County, which was an action to recover the deficit balance in Friedman’s account resulting from losses in 1979 silver futures trading. The Florida action was dismissed in its entirety on September 27, 1983.
Friedman's counsel represented to the district court that he intended to use in the Florida state court action, as well as in the Illinois action, the documents sought by the CFTC and SEC subpoenas.
. Part (a) has been modified to demand production of an index of all witnesses who testified in the SEC’s investigation, and not transcripts of testimony. Friedman has obtained transcripts of the testimony of the Hunts and of Charles Mercer directly from those parties.
. Section 222(5) of the Futures Trading Act of 1982, 7 U.S.C. § 12(f) (Supp.1983) provides in pertinent part:
The Commission shall disclose information in its possession pursuant to a subpoena or summons only if—
(1) A copy of the subpoena or summons has been mailed to the last known home or business address of the person who submitted the information that is the subject of the subpoena or summons
(2) At least fourteen days have expired from the date of such mailing of the subpoena or summons, or such other notice.
. Section 8(a) of the Commodity Exchange Act, 7 U.S.C. § 12(a) (Supp.1983), as amended reads:
For the efficient execution of the provisions of this Act, and in order to provide information for the use of Congress, the Commission may make such investigations as it deems necessary to ascertain the facts regarding the operations of boards of trade and other persons subject to the provisions of this Act. The Commission may publish from time to time the results of any such investigation and such general statistical information gathered therefrom as it deems of interest to the public: Provided, That except as otherwise specifically authorized in this Act, the commission may not publish data and information that would separately disclose the business transactions or market positions of any person and trade secrets or names of customers: Provided further, That the Commission may withhold from public disclosure any data or information concerning or obtained in connection with any pending investigation of any person.
. We endeavor to preserve our awareness of the context of two underlying lawsuits with many parties, within which context the district court ruled on February 9, 1983. However, for purposes of further proceedings arising from the subpoenas, only Friedman's action in Illinois, and only the surviving defendant in that action, the Board of Trade, need be considered.
. Hereinafter, we will refer only to the contentions of CFTC, without repetition of the fact that SEC has joined in CFTC’s claim of privilege as to SEC’s silver investigation file.
. We consider below whether there is a statutory bar to disclosure: Section 8(a) of the Commodities Exchange Act.
. The dissent observes that in addition to the common-law law-enforcement investigatory files privilege, CFTC contended that two other privileges barred production (the privilege for intragovernmental deliberative documents and the privilege for official information or required reports), and that on remand CFTC remains free to assert at least the privilege for intragovernmental deliberative documents. In Jordan v. United States Dept. of Justice, 591 F.2d 753, 779 (D.C.Cir.1978), we were emphatic in our rejection of the assertion of privileges piecemeal from time to time in the course of litigation. We note that in its written submission to the district court, CFTC contended principally for the privilege for law-enforcement investigatory files, adverted very briefly to the existence of a privilege for intragovernmental deliberative documents, and made no mention of a privilege for official information or required reports. It will be for the district court to determine on remand, in light of our ruling in Jordan, whether CFTC remains free to assert any privilege other than that for law-enforcement investigatory files.
. Suggestions to the contrary appearing in Freeman v. Seligson, 405 F.2d 1326, 1336-40 (D.C.Cir.1968) must be viewed in the context of the threshold burden of showing good cause for the discovery of documents which was part of Rule 34 and, by analogy, Rule 45, Fed.R.Civ.P. prior to the 1970 amendments.
. See note 4, supra.
. Third party contributors may be permitted to intervene for the purpose of asserting any privilege they may hold with respect to the subpoenaed information. Freeman, 405 F.2d at 1351-2; 17 C.F.R. § 145.9 (1983).
. Section 239 of the FTA provides, "This Act shall be effective upon the date of enactment of this Act." 7 U.S.C. § 2 note (Supp.1983).
. In so describing movant’s posture, we imply nothing whatever, of course, concerning the merits of this discovery dispute or of the suit in the federal court in Illinois. Indeed, his efforts seem consonant, superficially, at least, with those of the CFTC and SEC as to the silver crisis.
. The dissenting opinion seems to fault appellant Friedman for litigating the subpoena questions on appeal for over a year. He is not responsible for the length of time this court of appeals has required to hear and decide the matter.
