opinion: STEVENS, Circuit Judge.
  In this class action plaintiffs claim that the United States Army collects and retains more information about civilians than it needs. They pray for an injunction against the Army’s massive domestic intelligence operation because it discourages the free expression of ideas.
  Plaintiffs are members of the class represented by Arlo Tatum and other named plaintiffs in litigation commenced in the United States District Court for the District of Columbia on February 17, 1970, in which the same claims are asserted. After that case was filed and the public became aware of the scope of the Army’s domestic intelligence activities, hearings were held by a committee of the United States Senate in which the Army was severely criticized. On or about June 7, 1970, the Army discontinued most of the unnecessary speech inhibiting intelligence activities of which plaintiffs complain.
  On April 29, 1970, the District Court for the District of Columbia dismissed the Tatum complaint on the ground that it raised issues which were not justiciable. On May 4, 1970, notices of appeal were filed, and on April 27, 1971, the Court of Appeals for the District of Columbia rendered scholarly opinions, Tatum v. Laird, 144 U.S.App.D.C. 72, 444 F.2d 947, exhaustively discussing the legal issues, reversed the district court order and remanded the case for trial. Subsequently, the Supreme Court granted certiorari, heard oral argument, and now has the Tatum case under advisement.
  The case before us was filed on December 21, 1970. Immediately thereafter plaintiffs moved for a preliminary injunction and defendants filed a motion to dismiss the complaint. In response to defendants’ motion to dismiss, plaintiffs’ counsel repeatedly urged the court to listen to the evidence to be offered in support of the application for a preliminary injunction and to evaluate the sufficiency of the pleading in the light of that evidence. Accordingly, the trial judge heard evidence for four days, found that the Army had indeed engaged in some unnecessary — in fact some stupid and wasteful — intelligence activities, but found no significant threat to First Amendment freedoms, and therefore denied injunctive relief and dismissed the complaint.
  We are satisfied that the complaint was properly dismissed. Since the Supreme Court opinion in Tatum will no doubt render our discussion of the law obsolete, we shall only briefly identify the reasons for our conclusion which, we are convinced, will be the same whether Tatum is affirmed or reversed.
  First, we assume, without deciding, that a “massive” domestic intelligence operation conducted by the United States Army can have a sufficient deterrent effect on the free expression of political ideas to give individual citizens affected thereby standing to challenge the legitimacy of such an operation.
  Second, we assume, without deciding, that the domestic intelligence activities as conducted by the Army prior to June 7, 1970, were illegitimate, and that the excesses could be excised by judicial decree.
  Third, the evidence in the record, as appraised both by the district court and by this court, establishes that the Army’s intelligence activities subsequent to June 7, 1970 — or more specifically on December 21, 1970, when the complaint was filed — were not of the massive, overly broad character described in the complaint and in counsel’s argument. Thus, the claimed intrusion on First Amendment rights was clearly less significant at the time this complaint was filed than it was at the time the Tatum complaint was filed.
  Fourth, to the extent plaintiffs’ claims are justiciable, they can be most effectively asserted in the Tatum litigation. Both this complaint and the Tatum complaint are class actions; except for different named class representatives and other differences of no significant import, the allegations of the two complaints and the prayers for relief are identical — in most instances the complaint in this case reproduces verbatim the language of the Tatum complaint; a reading of the complaint leads one to the inescapable conclusion that the two classes are identical; the evidence adduced at the hearing on the preliminary injunction indicates, even if the parallel complaints did not, that there is cooperation between the Tatum plaintiffs and the plaintiffs in this case and that the same witnesses would give important testimony in both proceedings. If there is some difference in the allegations of the two complaints which we have overlooked, it would be a simple matter to amend the Tatum complaint if the Supreme Court affirms the remand of that case for trial.
  If the Supreme Court holds that the allegations in the Tatum complaint may not be tried, that ruling will certainly dispose of this ease as veil. If, however, that Court affirms the Court of Appeals for the District of Columbia and Tatum is remanded for trial, no purpose will be served by conducting a duplicate trial in this Circuit.
  We conclude that if the issues presented by this complaint are to be tried, the principle of comity dictates that they be tried in the District Court for the District of Columbia. Though rejecting its application on the facts of the case before him, Judge Hastings has concisely stated the relevant principle:
  “Briefly, the comity doctrine is one based on notions of sound judicial administration and requires that when two identical actions are filed in courts of concurrent jurisdiction, the one which first acquired jurisdiction should be the one to try the lawsuit. The purposes of the rule are to avoid unnecessarily burdening courts and to avoid possible embarrassment from conflicting results.” Great Northern Railway Co. v. National Railroad Adjustment Board, 422 F.2d 1187, 1193 (7th Cir. 1970).
  Plaintiffs seek declaratory and injunctive relief; it is therefore especially appropriate that the principles of comity be applied. Mr. Justice Frankfurter has written:
  “The Federal Declaratory Judgments Act, facilitating as it does the initiation of litigation by different parties to many-sided transactions, has created complicated problems for coordinate courts. Wise judicial administration, giving regard to conservation of judicial resources and comprehensive disposition of litigation, does not counsel rigid mechanical solution of such problems. The factors relevant to wise administration here are equitable in nature. Necessarily, an ample degree of discretion, appropriate for disciplined and experienced judges, must be left to the lower courts. . . .” Kerotest Manufacturing Co. v. C-O-Two Fire Equipment Co., 342 U.S. 180, 183-184, 72 S.Ct. 219, 221, 96 L.Ed. 200.
  Here, the issues were first raised in the District of Columbia litigation. As to the two cases, as we have noted, the class is the same; the allegations are the same; the prayers for relief are the same. If the requested relief is granted in the Tatum litigation, there is no additional relief that plaintiffs could obtain in this circuit. If injunctive relief is required, it is best administered by one court; that court should be the one in which the relief was first sought.
  In view of the serious character of the charges in the complaint and the representations made in support of the application for a preliminary injunction, we believe the Chancellor properly exercised his discretion in conducting an evidentiary hearing notwithstanding the fact that an analogous class action had been dismissed by the District Court for the District of Columbia. Since there had been no formal determination of the class in that proceeding, these plaintiffs were not barred from commencing this litigation. On the other hand, equitable considerations also support a decision to abstain from permitting a second class action involving the same issues to proceed if the Tatum complaint is ultimately upheld. Quite obviously the judiciary should proceed with the utmost restraint in litigation seeking to enjoin activities carried on by the Army. Even assuming an overriding public interest in the prosecution of one such case, there is no pressing need for a second.
  Wise judicial administration requires that we defer to the jurisdiction of the District of Columbia district court. Accordingly, we affirm the order denying the motion for preliminary injunction and hold that the complaint was properly dismissed. That determination of course, is made without prejudice to whatever rights plaintiffs or other members of the class which they represent may have.
  Affirmed.
  . That complaint is in the record as an attachment to the defendants’ motion to dismiss.
  . The doctrine of comity is not new, of course. See Covell v. Heyman, 111 U.S. 176, 182, 4 S.Ct. 355, 358, 28 L.Ed. 390:
  “The forbearance which courts of coordinate jurisdiction, administered under a single system, exercise towards each other, whereby conflicts are avoided, by avoiding interference with the process of each other, is a principle of comity with perhaps no higher sanction than the utility which comes from concord. . . .”
  See also Kline v. Burke Construction Co., 260 U.S. 226, 229, 43 S.Ct. 79, 67 L.Ed. 226; Milwaukee Gas Specialty Co. v. Mercoid Corp., 104 F.2d 589, 592 (7th Cir. 1939). Later cases include Hilton Hotels Corp. v. Weaver, 117 U.S.App.D.C. 83, 325 F.2d 1010 (1963), cert, denied, 376 U.S. 951, 84 S.Ct. 968, 11 L.Ed.2d 971; Mattel, Inc. v. Louis Marx & Co., 353 F.2d 421, 423-424 (2nd Cir.), cert. dismissed, 384 U.S. 948, 86 S.Ct. 1475, 16 L.Ed.2d 546; Mann Manufacturing, Inc. v. Hortex, Inc., 439 F.2d 403, 408 and n. 6 (5th Cir. 1971). As the cited cases indicate, the problem most often arises in patent litigation; application of the doctrine may or may not result in deferral to the jurisdiction of first filing, depending on the facts of the case.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 
  
  Your task concerns the first listed appellant. The nature of this litigant falls into the category "private organization or association", specifically "other". Your task is to determine what subcategory of private association best describes this litigant.
