Opinion for the Court filed by BAZELON, Circuit Judge.
Dissenting opinion filed by WILKEY, Circuit Judge.
On the motion of defendants in Halkin v. Helms, Civ. No. 75-1773 (D.D.C.), the district court entered an order on February 14, 1976 prohibiting the parties and counsel in that case from making any extra-judicial statements about information produced through discovery, and from publicly disclosing any material produced through discovery, except by making such material a part of the court record. Plaintiffs in that case now petition this court for a writ of mandamus and/or prohibition1 vacating the district court’s order.
I. BACKGROUND
Plaintiffs in Halkin are a number of individuals and organizations who allege that *261certain government agencies, principally the Central Intelligence Agency and the National Security Agency, as well as several common carriers, conducted unlawful programs of surveillance of United States citizens who opposed the war in Vietnam or engaged in other lawful political activities. Plaintiffs seek damages and equitable relief for alleged violations of their constitutional and statutory rights. Neither plaintiffs nor defendants in Halkin have demanded a jury trial.
After filing their complaint, plaintiffs requested, under Fed.R.Civ.P. 34, documents relating to Operation CHAOS, the code name for the CIA’s surveillance of anti-war activists. On December 30, 1976, defendants made available to plaintiffs some of these documents, constituting approximately 3000 pages. Appendix (App.) at 10. At the same time, defendants also filed a document styled “Federal Defendant George Bush’s Partial Response to Plaintiffs’ First Request for Production of Documents,” App. at 6-9, which indicated that the produced documents had been purged of all matter which the Government asserted would (1) impair the United States’ diplomatic and foreign relations, including the CIA’s relationships with foreign intelligence or security services, or (2) reveal CIA intelligence sources and methods or the investigative or intelligence activities of another United States government agency, or (3) implicate the privacy interests of third parties.2 Defendants sought no protective order under Fed.R.Civ.P. 26(c) limiting plaintiffs’ use of these documents,3 nor was there any express or implied agreement between the parties concerning their use.
Plaintiffs’ counsel, however, believed that some of these documents contained important information not previously known con*262cerning the operation of CHAOS. App. at 13. On January 24, 1977, plaintiffs gave written notice that they intended to release several documents on January 31, and provided defendants with a copy of the press release by which they planned to announce the availability of the documents.4
In response, defendants moved for a protective order pursuant to Rule 26(c). Citing Local Rule l-27(d),5 defendants argued that public disclosure of the documents would be “prejudicial to the defendants’ right to adjudication of the issues in this civil action in an uncolored and unbiased climate, includ*263ing a fair trial.” App. at 24.6 Defendants’ motion was not accompanied by any affidavits, nor was any other evidence adduced in its support.
Plaintiffs opposed defendants’ motion, arguing that a protective order would lack the “good cause” required by Fed.R.Civ.P. 26(e) and would violate the First Amendment. As part of their opposition plaintiffs lodged with the district court three documents and the press statement which plaintiffs asserted they had intended to release.7
On February 14, 1977, the district court signed defendants’ proposed order restraining the parties and their counsel from publicly disclosing information obtained through discovery. The court made no findings of fact, but stated that disclosure would be “contrary to rules applicable to the conduct of litigation before this Court and inconsistent with the obligations of parties and their counsel to further the just determination of matters within its jurisdiction.” 8 Although the parties claim to have complied with this order, the New York Times somehow acquired access to these documents and, on February 22, 1977, reported on their contents. App. at 30.
Plaintiffs have petitioned this court for a writ of mandamus9 to vacate the district court’s order. Since jurisdiction to issue this extraordinary writ depends upon our evaluation of the merits of petitioners’ claims, we defer discussion of the propriety of relief until after our evaluation of the substantive issues raised by this petition. Colonial Times, Inc. v. Gasch, 166 U.S.App.D.C. 184, 187, 509 F.2d 517, 520 (1975).
The importance of the issue presented by this case, and the relatively scant attention it has received in previous cases, requires us to consider in some depth petitioners’ claim.
II. THE FIRST AMENDMENT AND THE DISCOVERY PROCESS
In many respects, the order of February 14 is comparatively narrow. It does not prohibit comment by the news media, but only extrajudicial statements by the parties and their counsel.10 Nor does it *264forbid publication of information of public record, or information acquired outside the court’s processes, but only publication of documents and information obtained in discovery. Even if the order is relatively narrow, however, it restrains petitioners from communicating matters of public importance for an indefinite period of time.11 As such, it constitutes direct governmental action limiting speech and must be carefully scrutinized in light of the First Amendment.
A. Judicial Prior Restraints
Plaintiffs characterize the order issued by the district court as a “prior restraint” of expression and argue therefore that the order, while not unconstitutional per se, nonetheless bears a “heavy presumption” against its validity. Southeastern Promotions Ltd. v. Conrad, 420 U.S. 546, 558, 95 S.Ct. 1239, 43 L.Ed.2d 448 (1975).12 “The presumption against prior restraints is heavier — and the degree of protection broader — than that against limits on expression imposed by criminal penalties.” Id. at 558-59, 95 S.Ct. at 1246. Indeed, the Supreme Court has recently indicated that prior restraints “are the most serious and least tolerable infringement on First Amendment rights.” Nebraska Press Ass’n v. Stuart, 427 U.S. 539, 559, 96 S.Ct. 2791, 2803, 49 L.Ed.2d 683 (1976).
The term “prior restraint,” at common law, referred to a system of unreviewable administrative censorship or licensing.13 But the concept has not been so confined. In a long line of cases beginning with Near v. Minnesota, 283 U.S. 697, 51 S.Ct. 625, 75 L.Ed. 1357 (1931), the Supreme Court has extended the meaning of prior restraints to include judicial orders having an impact analogous to administrative censorship. Among the judicial orders that have been considered prior restraints are orders restraining extrajudicial comment about a pending or anticipated trial. In Nebraska Press Ass’n v. Stuart, 427 U.S. 539, 96 S.Ct. 2791, 49 L.Ed.2d 683 (1976), the Court held that an order prohibiting any publication or broadcast by the news media “strongly implicative” of an accused criminal defendant was a prior restraint, and indicated that such an order would survive constitutional scrutiny only in the most unusual circumstances.14
A judicial order pursuant to Rule 26(c) limiting lawyers’ and parties’ expression does possess many of the characteristics of an administrative licensing scheme, *265the paradigmatic prior restraint.15 At the same time, it is equally clear that such an order need not present the same dangers as many delegations of authority to an admin*266istrative censor,16 nor the same threat to expression generated by other judicial orders previously condemned as prior restraints.17
*267We do not believe, however, that the proper resolution of this case in the end turns on whether this order can be termed a prior restraint. We observe the admonition of Justice Frankfurter that the term “prior restraint” should not be used as “a talismanic test,” Kingsley Books, Inc. v. Brown, 354 U.S. 436, 441, 77 S.Ct. 1325 (1957), and do not begin our examination with an almost insurmountable presumption against the validity of this order. However, the fact that the order poses many of the dangers of a prior restraint is sufficient to require close scrutiny of its impact on protected First Amendment expression.
The dissent does not dispute that the order has many of the characteristics of a “prior restraint,” but contends that there are, in effect, two different types of prior restraints, one “solely directed at information and documents obtained in discovery” and a second covering all other orders restricting expression. Dissent at 285 of 194 U.S.App.D.C., at 204 of 598 F.2d. Restraining orders directed at discovery materials are subject to less stringent scrutiny than other restraining orders, according to the dissent, because “[t]he First Amendment interests of litigants in the promulgation of materials exacted from another party through the compulsory processes of the courts are much more limited and of a fundamentally different character” than litigants’ other First Amendment interests. Id. at 287 of 194 U.S.App.D.C., at 206 of 598 F.2d. We cannot agree with this bifurcated approach to the First Amendment’s protection for speech.
B. The First Amendment Interests of Litigants and Lawyers
1. The First Amendment Interest in Litigation and the Administration of Justice
Defendants correctly point out that attorneys “have historically been ‘officers of the courts[,]’ ” Goldfarb v. Virginia State Bar, 421 U.S. 773, 792, 95 S.Ct. 2004, 2016, 44 L.Ed.2d 572 (1975), and that they have a legal and ethical responsibility to safeguard the right to a fair trial.18 But lawyers’ responsibility to protect the fairness of the judicial process does not mean that lawyers and litigants surrender their First Amendment rights at the courthouse door. Even public officials who have special responsibilities to the court do not necessarily have a “more severely curtailed” right to freedom of expression than “the average citizen.” Wood v. Georgia, 370 U.S. 375, 393, 82 S.Ct. 1364, 8 L.Ed.2d 569 (1962).19
*268In fact, orders restraining extrajudicial comment by parties and lawyers have been uniformly held a serious restriction of fundamental First Amendment rights. In CBS, Inc. v. Young, 522 F.2d 234 (6th Cir.1975), for example, the court of appeals confronted an order forbidding court personnel, counsel, parties, and the parties’ “relatives, close friends, and associates” to discuss the case with the news media or the public. The court found the order impermissibly overbroad. Id. at 239. “According to its literal terms no discussions whatever about the case are permitted by the persons upon whom the ban is placed—whether prejudicial or innocuous, whether subjective or objective, whether reportorial or interpretive.” Id. at 239-40. The court concluded that the order was “an extreme example of a prior restraint upon freedom of speech and expression . . .” Id. at 240. Similarly, in Chase v. Robson, 435 F.2d 1059 (7th Cir. 1970), the appellate court considered an order that barred counsel and defendants from making any public statements about the merits of the case, the jury, the evidence, the witnesses, or the rulings of the court. Again, the reviewing court found insufficient justification for curtailing all of these statements; it concluded that the order was overbroad and that it constituted “a prior restraint on protected first amendment conduct.” Id. at 1062.20
Litigation itself is a form of expression protected by the First Amendment. The Supreme Court has recently stressed that litigation may be “a vehicle for effective political expression and association, as well as a means of communicating useful information to the public.” In re Primus, 436 U.S. 412, 431, 98 S.Ct. 1893, 1904, 56 L.Ed.2d 417 (1978).21 Moreover, as the Seventh Circuit has noted:
., in our present society many important social issues became entangled to some degree in civil litigation. Indeed, certain civil suits may be instigated for the very purpose of gaining information for the public. Often actions are brought on behalf of the public interest on a private attorney general theory. Civil litigation in general often exposes the need for governmental action or correction. Such revelations should not be kept from the public. Yet it is normally only the attorney who will have this knowledge or realize its significance. . . . Therefore, we should be extremely skeptical about any rule that silences that voice.22
It is thus indisputable that attorneys and parties retain their First Amendment rights even as participants in the judicial process. For the very reasons that have led courts to conclude that lawyers and parties retain their First Amendment rights generally, we conclude that those rights extend to discovery materials.
2. The First Amendment Interest in Discovery Materials
The inherent value of speech in terms of its capacity for informing the public does not turn on how or where the information was acquired. See First National Bank of Boston v. Bellotti, 435 U.S. 765, 778-783, 98 S.Ct. 1407, 55 L.Ed.2d 707 (1978). Even where information has been stolen, New York Times Co. v. United States, 403 U.S. 713, 91 S.Ct. 2140, 29 *269L.Ed.2d 822 (1971); Rodgers v. United States Steel Corp., 536 F.2d 1001, 1008 n. 16 (3d Cir.1976), or retained in violation of a security agreement, United States v. Marchetti, 466 F.2d 1309, 1317 (4th Cir.), cert. denied, 409 U.S. 1063, 93 S.Ct. 553, 34 L.Ed.2d 516 (1972), individuals who obtain such information have been held to have First Amendment rights in its dissemination.
A party’s right to disseminate information is far stronger for discovery materials than for information that has been stolen or obtained in breach of contract. Generally speaking, when a party obtains documents or information through the discovery process, he can “use that information in any way which the law permits.” Leonia Amusement Corp. v. Loew’s, Inc., 18 F.R.D. 503, 508 (S.D.N.Y.1955). Accord Essex Wire Corp. v. Eastern Electric Sales Co., 48 F.R.D. 308, 312 (E.D.Pa.1969). The discovery rules themselves place no limitations on what a party may do with materials obtained in discovery. Under Rule 26(c), Fed.R.Civ.P., the party or person from whom discovery is sought must establish “good cause” for any restriction on the use of discovery documents.23 The implication is clear that without a protective order materials obtained in discovery may be used by a party for any purpose, including dissemination to the public.24
Defendants do not argue that discovery materials generically constitute one of the “well-defined and narrowly limited classes of speech, the prevention and punishment of which have never been thought to raise any Constitutional problem.” Chaplinsky v. New Hampshire, 315 U.S. 568, 571-72, 62 S.Ct. 766, 769, 86 L.Ed. 1031 (1942). Unlike libelous falsehoods, Gertz v. Robert Welch, Inc., 418 U.S. 323, 340, 94 S.Ct. 2997, 41 L.Ed.2d 789 (1974), or obscenities, Miller v. California, 413 U.S. 15, 23, 93 S.Ct. 2607, 37 L.Ed.2d 419 (1973), or fighting words, Chaplinsky, 315 U.S. at 572, 62 S.Ct. at 769, discovery materials cannot be described as a class of utterances of “no essential part of any exposition of ideas,” or of “slight social value as a step to truth.” Id. at 572, 62 S.Ct. at 769. In fact, the information contained in discovery documents in this case, pertaining to an allegedly illegal program of Government surveillance of citizens opposed to the war in Vietnam, lies near the heart of the information protected by the First Amendment. First National Bank of Boston v. Bellotti, 435 U.S. at 781, 98 S.Ct. 1407; Mills v. Alabama, 384 U.S. 214, 218, 86 S.Ct. 1434, 16 L.Ed.2d 484 (1966).
Defendants, citing International Products Corp. v. Koons, 325 F.2d 403 (2d Cir.1963), nevertheless contend that plaintiffs voluntarily waived any First Amendment rights in discovery materials when they entered into the discovery process. Although one court, in dicta, has suggested that Koons can be interpreted as standing for this extreme proposition, Rodgers v. United States Steel Corp., 536 F.2d at 1006, we think it should be read less broadly.
At issue in Koons was a restraining order forbidding the parties from publicly disclosing information contained in a deposition. Disclosure of the information, involving illegal payments to officials in South America, was said to be “contrary to the best interests of the foreign policy of the United States.” 325 F.2d at 405. The court ruled that to the extent the order barred disclosure of information obtained before the deposition was taken, it was an impermissible prior restraint on First Amendment rights. Id. at 408-09. The court also stated, however, that
[t]he portion of the order which seals the deposition of Seldes and limits defendants and others in their use of information obtained therefrom was plainly authorized by F.R.Civ.Proc. [26(c)] and we enter*270tain no doubt as to the constitutionality of a rule allowing a federal court to forbid the publicizing, in advance of trial, of information obtained by one party from another by use of the court’s processes.
Id. at 407.
This passage does not say that parties have no First Amendment rights in discovery materials. At most, it establishes that a properly drawn restraining order, supported by a proper showing of good cause, is compatible with the First Amendment.25 Significantly, this interpretation of Koons has been recently adopted in a case expressly holding that a party has First Amendment rights in information obtained in the discovery process. Reliance Insurance Co. v. Barron's, 428 F.Supp. 200, 204-05 (S.D.N.Y.1977). See Davis v. Romney, 55 F.R.D. 337, 344-45 (E.D.Pa.1972).
If Koons does stand for the proposition that the parties in a civil action waive all First Amendment rights in discovery materials, as the Rodgers court suggested in dicta,26 then we think it is wrong. Waivers of First Amendment rights are to be inferred only in “clear and compelling” circumstances. Curtis Publishing Co. v. Butts, 388 U.S. 130, 145, 87 S.Ct. 1975, 18 L.Ed.2d 1094 (1967) (Harlan, J.). See Johnson v. Zerbst, 304 U.S. 458, 464, 58 S.Ct. 1019, 82 L.Ed. 1461 (1938); Rodgers v. United States Steel Corp., 536 F.2d at 1007 n. 14. Plaintiffs here never agreed to forego any First Amendment claim related to discovery materials. Nor do we find clear and compelling evidence of an implied waiver of First Amendment rights in the system of civil discovery. As noted above, the presumption under the discovery rules is that a party may do anything it wants with discovery material, absent a protective order entered “for good cause shown.” Fed.R.Civ.P. 26(c).
Furthermore, assuming arguendo that parties implicitly agree not to publicly disclose information obtained in the discovery process, this does not establish a waiver of First Amendment rights. Even where individuals have entered into express agreements not to disclose certain information, either by consent agreement, Crosby v. *271 Bradstreet Co., 312 F.2d 483 (2d Cir.), cert. denied, 373 U.S. 911, 83 S.Ct. 1300, 10 L.Ed.2d 412 (1963); or by an employment contract and secrecy oath, United States v. Marchetti, 466 F.2d 1309 (4th Cir.), cert. denied, 409 U.S. 1063, 93 S.Ct. 553, 34 L.Ed.2d 516 (1972), the courts have held that judicial orders enforcing such agreements are prior restraints implicating First Amendment rights.
Defendants also appear to argue that because plaintiffs can obtain discovery materials only through the court’s processes, the court can condition their access to these materials without regard to the First Amendment. Fed.Res.Br. at 27. This argument, first and most fundamentally, confuses plaintiffs’ right of access to materials with restraints imposed on materials after they have been obtained. We agree that plaintiffs do not have a First Amendment right of access to information not generally available to members of the public. Pell v. Procunier, 417 U.S. 817, 834, 94 S.Ct. 2800, 41 L.Ed.2d 495 (1974); Zemel v. Rusk, 381 U.S. 1, 16-17, 85 S.Ct. 1271, 14 L.Ed.2d 179 (1965); see also Nixon v. Warner Communications, Inc., 435 U.S. 589, 609-10, 98 S.Ct. 1306, 55 L.Ed.2d 570 (1978). A prohibition on what plaintiffs may say about information once they have obtained it, however, directly implicates the First Amendment.27 Landmark Communications, Inc. v. Virginia, 435 U.S. 829, 837-38, 98 S.Ct. 1535, 56 L.Ed.2d 1 (1978). Even if plaintiffs have no right to discovery materials, a court cannot condition the “privilege” of access on a waiver of First Amendment rights. As the Court observed in Perry v. Sindermann, 408 U.S. 593, 597, 92 S.Ct. 2694, 2697, 33 L.Ed.2d 570 (1972):
even though a person has no “right” to a valuable governmental benefit and even though the government may deny him the benefit for any number of reasons, there are some reasons upon which the government may not rely. It may not deny a benefit to a person oh a basis that infringes his constitutionally protected interests — especially, his interest in freedom of speech. For if the government could deny a benefit to a person because of his constitutionally protected speech or associations, his exercise of those freedoms would in effect be penalized and inhibited. This would allow the government to “produce a result which [it] could not command directly.” Speiser v. Randall, 357 U.S. 513, 526, 78 S.Ct. 1332, 2 L.Ed.2d 1460. Such interference with constitutional rights is impermissible.28
The conclusion that First Amendment rights attach to materials made available through the discovery process does not, however, end our inquiry. As plaintiffs acknowledge, the First Amendment is not an absolute, see Near v. Minnesota, 283 U.S. at 716, 51 S.Ct. 625, 75 L.Ed. 1357, and the protection afforded the exercise of First Amendment rights may be limited in certain narrow circumstances. In particular, protection of a subordinating public interest may justify narrowly drawn restrictions of First Amendment rights, *272 NAACP v. Button, 371 U.S. 415, 438, 83 S.Ct. 328, 9 L.Ed.2d 405 (1963). Thus, the appropriate constitutional standard governing the issuance of restraining orders under Rule 26(c) must take account of the important public interests in the functioning of the discovery process, and the unique characteristics of that process, as well as the First Amendment interest in unfettered expression. We proceed, then, to an examination of the constitutional standard which the trial judge must apply before entering a restraining order under Rule 26(c).
C. The Constitutional Standard
Initially, the trial court must determine whether a particular protective order in fact restrains expression and the nature of that restraint. First Amendment interests will vary according to the type of expression subject to the order. An order restraining publication of official court records open to the public,29 or an order restraining political speech,30 implicates different interests than an order restraining commercial information.31 The interests will also vary according to the timeliness of the expression. An order restraining highly newsworthy information32 raises a different issue than a temporary restraint of materials having “constant but rarely topical interest.” 33
The court must then evaluate such a restriction on three criteria: the harm posed by dissemination must be substantial and serious;34 the restraining order must be narrowly drawn and precise;35 and there must be no alternative means of protecting the public interest which intrudes less directly on expression.36
*273In assessing the propriety of a protective order in each case (/. e., whether there is “good cause” for an order which restricts expression), the trial court must consider and make the necessary findings on each element of the standard. Certain general considerations, however, will apply to most requests for a restraining order under Rule 26(c).
1. Nature of the Harm Posed by Dissemination
Widely varying interests have been advanced in support of restraining orders, from protection of national security information, see International Products Corp. v. Koons, 325 F.2d 403 (2d Cir.1963), to preservation of privileged information, Rodgers v. United States Steel Corp., 536 F.2d 1001 (3d Cir.1976), to maintenance of trade secrets, Natta v. Zletz, 405 F.2d 99 (7th Cir.1968). The weight of these interests will vary from case to case.
Rule 26 establishes a mechanism for accommodating the interest in “[m]utual knowledge of all the relevant facts gathered by both parties,” Hickman v. Taylor, 329 U.S. 495, 507, 67 S.Ct. 385, 392, 91 L.Ed. 451 (1947), with these countervailing interests. The Rule requires general disclosure of information “relevant to the subject matter involved in the pending action,” Fed.R.Civ.P. 26(b), unless the party from whom discovery is sought obtains a protective order to shield some competing interest. Id. at 26(c). To insure that this mechanism functions properly, the trial court must have flexibility in fashioning appropriate protective orders, including restraining orders.37 Protective orders not only serve to protect against unfairness in a particular judicial proceeding, but may also help preserve the effective functioning of the civil discovery system more generally. A smoothly operating system of liberal discovery is in the interests of litigants and society as a whole, for it contributes to a full and fair airing of all material facts in controversy.38 If parties are to be forthcoming in responding to requests for discovery, they must have fair assurance that legitimate countervailing interests will be protected, if necessary by a restraining order.
(5) that discovery be conducted with no one present except persons designated by the court; (6) that a deposition after being sealed can be opened only by order of the court; (7) that a trade secret or other confidential research, development, or commercial information not be disclosed or be disclosed only in a designated way
There can be no doubt that protecting the fairness of the judicial process is a substantial interest, for it is central to the maintenance of liberty. Accordingly, courts have always valued the need to protect the administration of justice from “abuses, oppression and injustice.” Gumbel v. Pitkin, 124 U.S. 131, 144, 8 S.Ct. 379, 31 L.Ed. 374 (1888). “[T]he right of courts to conduct their business in an untrammeled way lies at the foundation of our system of government . . . Wood v. Georgia, 370 U.S. at 383, 82 S.Ct. at 1369.
When asked for a protective order based on the right to a fair trial, the trial court should assess the strength of the interest according to the following factors:
(a) Civil versus criminal trial. Although the right to a fair trial is fundamental to *274both civil and criminal litigation,39 there are important distinctions between the two in this context.
[A]lthough we rightfully place a prime value on providing a system of impartial justice to settle civil disputes, we require even a greater insularity against the possibility of interference with fairness in criminal cases. Perhaps this is symbolically reflected in the Sixth Amendment’s requirement of an “impartial jury” in criminal cases whereas the Seventh Amendment guarantees only “trial by jury” in civil cases.
Chicago Council of Lawyers v. Bauer, 522 F.2d 242, 257-58 (7th Cir.1975), cert. denied, 427 U.S. 912, 96 S.Ct. 3201, 49 L.Ed.2d 1204 (1976).40
(b) Bench trial versus jury trial. The principal concern about pretrial publicity is that it will prejudice a lay jury. It is true that judges, too, are human. Cox v. Louisiana, 379 U.S. 536, 565, 85 S.Ct. 453, 13 L.Ed.2d 471 (1965). But life-tenured judges are “supposed to be men of fortitude, able to thrive in a hardy climate.” Craig v. Harney, 331 U.S. 367, 376, 67 S.Ct. 1249, 1255, 91 L.Ed. 1546 (1974); In re Little, 404 U.S. 553, 555, 92 S.Ct. 659, 30 L.Ed.2d 708 (1972). Although the threat of prejudicial publicity is entitled to some weight in a bench trial, see Chicago Council of Lawyers v. Bauer, 522 F.2d at 256-57, it is entitled to greater weight where a jury trial has been demanded.
2. Precision of the Restriction
To establish “good cause” for a protective order under Rule 26(c), “[t]he courts have insisted on a particular and specific demonstration of fact, as distinguished from stereotyped and conclusory statements. . . ” 8 Wright & Miller, Federal Practice and Procedure § 2035 at 265 (1970).41 This requirement is constitutionally mandated when the order restricts expression, see Chase v. Robson, 435 F.2d at 1061, to assure that the order is no broader than absolutely necessary to protect the countervailing interest. An order restraining speech cannot be based on a record that reveals only naked speculation that the right to a fair trial might be jeopardized. Nebraska Press Ass’n, 427 U.S. at 569, 96 S.Ct. 2791. Thus, in determining whether “good cause” exists to issue a restraining order limited to discovery material and to lawyers and parties, the trial court must also require a specific showing that dissemination of the discovery materials would pose a concrete threat to an important countervailing interest.42
*275Except in unusual circumstances, a protective order issued under Rule 26(c) can be tailored to avoid many of the infirmities associated with judicial restraints on expression. If the party against whom discovery is sought makes a timely motion for a protective order, the court can examine the relevant documents or information in camera before determining whether a restraining order should issue. See Kerr v. United States District Court, 426 U.S. 394, 404-06, 96 S.Ct. 2119, 48 L.Ed.2d 725 (1976). In appropriate cases, opposing counsel should be permitted to participate in such in camera proceedings, so that the judge will have the benefit of adversarial presentation.43 The court should therefore have no difficulty drafting a narrow order covering only specifically identified materials that may be proscribed consistent with the First Amendment. In short, when judicial restraints on discovery materials are involved, there should be no need for the court to issue vague or overbroad orders, or to speculate “in advance what [the speaker] will say.” Southeastern Promotions Ltd. v. *276 Conrad, 420 U.S. at 559, 95 S.Ct. 1239, 1246, 43 L.Ed.2d 448.
3. Less Intrusive Alternatives
A protective order pursuant to Rule 26(c) may be the least intrusive means of achieving the goals of protecting the fairness of the judicial process and preserving the discovery system. An order directed only against parties and lawyers undoubtedly represents a less sweeping curtailment of First Amendment rights than, e. g., an order broadly restraining the press.44 Although, from the public’s point of view, the probable effect of such an order will be to dry up a valuable source of news about the trial, and although this is a serious consequence, CBS, Inc. v. Young, 522 F.2d at 239, an order binding the entire news media will likely have the much more serious effect of depriving the public information about the trial altogether. Similarly, an order barring all comment on a pending case by lawyers and litigants would restrict expression more drastically.45
The only plausible alternative to a protective order may be the denial of discovery altogether. Such a result benefits no one, for in neither event will the public learn the contents of the discovery material, and when discovery is denied, the litigant will be deprived of information relevant to the preparation of the case.46
However, when the threatened harm is prejudice to a fair trial, a number of alternatives less restrictive of expression may be available. They include
(a) change of trial venue to a place less exposed to intense publicity . ; (b) postponement of the trial to allow public attention to subside; (c) searching questioning of prospective jurors . . to screen out those with fixed opinions as to guilt or innocence; (d) the use of emphatic and clear instructions on the sworn duty of each juror to decide the issues only on evidence presented in open court[;] (e) [sequestration of jurors [to] . . . enhanceQ the likelihood of dissipating the impact of pretrial publicity and emphasize^ the elements of the jurors’ oaths.
Nebraska Press Ass'n, 427 U.S. at 563-64, 96 S.Ct. at 2805; see also Sheppard v. Maxwell, 384 U.S. 333, 357-62, 86 S.Ct. 1507, 16 L.Ed.2d 600 (1966). Not all of these measures will be available or feasible in every case, but they should be carefully considered before resorting to a restraining order.
These considerations demonstrate that, in appropriate cases, an order restricting the dissemination of discovery materials under Rule 26(c) may survive constitutional scrutiny. We stress, however, that in each case, before entering a protective order that restricts expression, the trial judge must determine that it meets those criteria mandated by the First Amendment. Different orders will have different impact on expression. Only in the context of particular discovery material and a particular trial setting can a court determine whether the threat to substantial public interests is sufficiently direct and certain. Only in a particular case can the judge determine whether an order is sufficiently narrow and precise to accomplish the desired goal with the *277least restriction on expression. And only in the particular case can the judge determine whether alternative methods with less intrusive impact on expression could accomplish the same goal.47
III. THE ORDER OF FEBRUARY 14,1977
Applying these principles, we have no difficulty concluding that the district court’s order of February 14, 1977 is seriously infirm. By preventing plaintiffs from divulging or commenting on the documents at issue, the order restrained them from criticizing certain government practices. To justify such a restriction on political expression, the government does not contend that it is necessary to protect national security or the privacy of third parties.48 Rather, counsel for defendants merely asserted that the intended news release would be “prejudicial to adjudication of these issues . . . in an uncolored and unbiased climate,”49 without providing any evidence to support this conclusory allegation.50
The district court made no evaluation of the First Amendment interests at stake, nor any finding that release of the documents would preclude a fair trial. Yet the district court broadly restrained the dissemination of an indeterminate amount of material of unknown content, barring extra-judicial statements about any discovery documents not made part of the public record. The order bars plaintiffs and their counsel from making extra-judicial statements about any discovery documents not made part of the public record. When the order was issued, plaintiffs had 55 CIA documents in their possession, App. at 23, and defendants had promised to hand over additional documents in the near future. Supplementary Appendix (Supp.App.) at 34-35. But the only materials the court had actually examined, in addition to the moving papers, memoranda, and correspondence between the parties, were: a two-paragraph letter from counsel for plaintiffs describing three documents plaintiffs proposed to release to the news *278media; photocopies of these three documents; and a draft press release, slightly over one page in length, interpreting the significance of these three documents. The court accordingly had no way of knowing what was contained in the bulk of the materials enjoined, or whether material other than the three documents and press release would be prejudicial if released.51
The district court failed even to assess the specific harm posed by the three documents actually before it, concluding only that “extra-judicial statements of disclosure of discovery materials . . . are contrary to rules applicable to the conduct of litigation before this Court and inconsistent with the obligations of parties and their counsel to further the just determination of matters within its jurisdiction. . . .” App. at l.52
Finally, the defendants made no showing, nor the court any finding, that potential prejudice could not be avoided by means less intrusive on expression.53
Judged by the standards imposed by Rule 26(c) and the First Amendment, the district court’s order is indisputably deficient. It prohibits political expression, yet it is silent as to its reasons, rests on no express findings, and is unsupported by any evidence.
IV. THE PROPRIETY OF MANDAMUS
Plaintiffs seek a writ of mandamus.54 We are empowered to issue such writs by the All Writs Act, 28 U.S.C. § 1651(a) (1976):
The Supreme Court and all courts established by Act of Congress may issue all writs necessary or appropriate in aid of their respective jurisdictions and agreeable to the usages and principles of law.55
*279The remedy of mandamus “is a drastic one, to be invoked only in extraordinary situations.” Kerr v. United States District Court, 426 U.S. at 402, 96 S.Ct. at 2123. Although the traditional touchstone for the use of the writ in aid of appellate jurisdiction has been the necessity of confining “an inferior court to a lawful exercise of its prescribed jurisdiction,” Roche v. Evaporated Milk Ass’n, 319 U.S. 21, 26, 63 S.Ct. 938, 941, 87 L.Ed. 1185 (1943), “courts have never confined themselves to an arbitrary and technical definition of ‘jurisdiction’ . . .” Will v. United States, 389 U.S. 90, 95, 88 S.Ct. 269, 273, 19 L.Ed.2d 305 (1967). Instead the writ has issued to correct those exceptional circumstances where there has been a “clear abuse of discretion or ‘usurpation of judicial power’ . . . Bankers Life & Casualty Co. v. Holland, 346 U.S. 379, 383, 74 S.Ct. 145, 148, 98 L.Ed. 106 (1953). See Schlagenhauf v. Holder, 379 U.S. 104, 110, 85 S.Ct. 234, 13 L.Ed.2d 152 (1964).
Although mandamus is a common law writ, it may, “like equitable remedies, ... be granted or withheld in the sound discretion of the Court . . .” Ex parte Peru, 318 U.S. 578, 584, 63 S.Ct. 793, 797, 87 L.Ed. 1014 (1943). Various doctrines govern the issuance of the writ. A petition for mandamus will be denied where “other adequate remedy is available,” id., or where its issuance would “thwart the congressional policy against piecemeal appeals.” Parr v. United States, 351 U.S. 513, 521, 76 S.Ct. 912, 917, 100 L.Ed. 1377 (1956). A petitioner for mandamus must thus demonstrate that “appeal is a clearly inadequate remedy.” Ex parte Fahey, 332 U.S. 258, 260, 67 S.Ct. 1558, 1559, 91 L.Ed. 2041 (1947), because he “will be damaged or prejudiced in a way not correctable on appeal.” Bauman v. United States District Court, 557 F.2d 650, 654 (9th Cir.1977). Consideration will be given to the severity and extent of this damage,56 and in particular to whether a petitioner' has lost precious constitutional rights.57 A petitioner for mandamus must also demonstrate that his “right to issuance of the writ is ‘clear and indisputable,’ ” Bankers Life & Casualty Co. v. Holland, 346 U.S. at 384, 74 S.Ct. at 148, although “writs will issue where the question of jurisdiction is undecided.” Morrow v. District of Columbia, 135 U.S.App.D.C. 160, 169, 417 F.2d 728, 737 (1969).
After careful consideration of these many factors, we conclude that mandamus is appropriate in this case. Plaintiffs have demonstrated the “special circumstances which . . . justify the issuance of the writ . . . .” Roche v. Evaporated Milk Ass’n, 319 U.S. at 31, 63 S.Ct. at 944. The order restrains plaintiffs’ expression, yet the court made no assessment of the strength of the continuing interest, the need for such a broad restriction, or the availability of alternative measures. In the absence of these findings, the petitioner’s right to be free of the restriction is clear and indisputable.
A number of courts have issued the writ of mandamus in order to strike down similar restraints.58 In this case the district court’s issuance of an overbroad restraint without any findings or particularized showing whatsoever is “so ‘egregiously erroneous’ that the action could be deemed a *280‘usurpation of power.’ ” Plekowski v. Ralston-Purina Co., 557 F.2d 1218, 1220 (5th Cir.1977). As the Third Circuit stated in reviewing a restraining order imposed by a district court on a party and her attorney, “[imposition of an order on anything less than a clear showing of particularized need removes it from the area of discretion unreviewable by mandamus.” Coles v. Marsh, 560 F.2d 186, 189 (3d Cir.), cert. denied, 434 U.S. 985, 98 S.Ct. 611, 54 L.Ed.2d 479 (1977).
Mandamus is especially appropriate in this case because plaintiffs have no other available adequate remedy. The Supreme Court has frequently noted the importance of timeliness to the rights of expression protected by the First Amendment. See, e. g., Nebraska Press Ass’n, 427 U.S. at 559, 96 S.Ct. 2791. “It is vital to the operation of democratic government that the citizens have facts and ideas on important issues before them. A delay of even a day or two n^ay be of crucial importance in some instances.” Carroll v. President and Commissioners of Princess Anne, 393 U.S. 175, 182, 89 S.Ct. 347, 352 (1968), quoting with approval, A Quantity of Books v. Kansas, 378 U.S. 205, 224, 84 S.Ct. 1723 (Harlan, J., dissenting). The Court has thus stressed the necessity of “immediate appellate review” of court issued restraints. National Socialist Party of America v. Skokie, 432 U.S. 43, 44, 97 S.Ct. 2205 (1977) (per curiam). See Cox Broadcasting Corp. v. Cohn, 420 U.S. 469, 485-86, 95 S.Ct. 1029 (1975). The duration of a trial is intolerably long when measured by this First Amendment clock. Bridges v. California, 314 U.S. 252, 268-69, 62 S.Ct. 190 (1941). Appeal is therefore a clearly inadequate remedy for plaintiffs. If they were forced to wait for appellate review until a final disposition of their case by the district court, their First Amendment rights to timely expression would be irretrievably lost. Nebraska Press Ass’n v. Stuart, 423 U.S. 1327, 1329-30, 96 S.Ct. 251, 46 L.Ed.2d 237 (1975) (Blackmun, J. in chambers); Citizens for a Better Environment v. City of Park Ridge, 567 F.2d 689, 691 (7th Cir.1975).
The only other remedy available to plaintiffs is to test the validity of the district court’s order through contempt proceedings. Even assuming, however, that the collateral bar rule would not apply to such a proceeding, see United States v. Ryan, 402 U.S. 530, 532 n. 4, 91 S.Ct. 1580, 29 L.Ed.2d 85 (1971), we conclude that it would not provide an adequate avenue of relief. The puissant threat of contempt might well suffocate the “breathing space” necessary for the exercise of petitioners’ First Amendment rights. See New York Times Co. v. Sullivan, 376 U.S. 254, 271-72, 84 S.Ct. 710, 11 L.Ed.2d 686 (1964). As the Seventh Circuit said in reviewing by mandamus a restraining order imposed by a district court, “[s]ince there is likelihood that the order will have a chilling effect on speech, defendants should not be forced to assert the invalidity of the order as a defense in a contempt proceeding. Dombrowski v. Pfister, 380 U.S. 479, 85 S.Ct. 1116,14 L.Ed.2d 22 (1965); NAACP v. Button, 371 U.S. 415, 83 S.Ct. 328, 9 L.Ed.2d 405 (1963).” Chase v. Robson, 435 F.2d at 1062. It is true that in the past we have required petitioners for mandamus to contest through contempt proceedings the validity of orders limiting the scope or availability of discovery. See National Right to Work Legal Defense and Education Foundation, Inc. v. Richey, 167 U.S.App.D.C. 18, 24, 510 F.2d 1239, 1245, cert. denied, 422 U.S. 1008, 95 S.Ct. 2631, 45 L.Ed.2d 671 (1975). Challenges to such discovery orders by mandamus are particularly disfavored,59 since they undermine the congressional policy against piecemeal appeals. See Usery v. Ritter, 547 F.2d 528, 532 (10th Cir. 1977); cf. Gardner v. Westinghouse Broadcasting Co., 437 U.S. 478, 98 S.Ct. 2451, 2453, 57 L.Ed.2d 364 (1978). This is because the underlying cause of action in the district court is derailed while such challenges are decided. In appropriate cases, however, courts have entertained challenges to dis*281covery orders by mandamus.60 In the instant ease, the underlying trial of petitioners’ claims continues unaffected by our disposition of this mandamus petition. The district court’s order, in other words, affects rights of petitioners that are “separable from, and collateral to” rights asserted in their complaint. Cohen v. Beneficial Industrial Loan Corp., 337 U.S. 541, 546, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). See United States v. Schiavo, 504 F.2d 1, 4-5 (3d Cir.) (en banc), cert. denied, 419 U.S. 1096; 95 S.Ct. 690, 42 L.Ed.2d 688 (1974).61
V.
In accordance with our usual practice, we will not issue the writ at this time. Instead, we will transmit a copy of this opinion to the district court to permit further proceedings in light of the discussion herein.62 Defendants are free to seek a new restraining order if they are able to present a detailed showing that a narrowly drafted order restraining promulgation of the documents by plaintiffs would be constitutional under the principles outlined in this opinion. It will remain open, however, for the parties to seek such further relief from this court as the circumstances may require.
Judgment accordingly.
