[245]*245OPINION AND ORDER
WILLIAM H. BECKER, Judge of the Panel.
General Factual Background
Certain plaintiffs and intervening plaintiffs, in civil treble damage antitrust actions pending in the United States District Courts for the Eastern District of Pennsylvania and the Southern District of New York, have moved for transfer under Section 1407, Title 28, U.S.C., to the Eastern District of Pennsylvania of the civil actions listed in the attached Schedule A. On the initiative of the Panel an order was issued to the parties to show cause why the civil actions listed in the attached Schedule B should not be transferred under Section 1407. The product involved in each of those actions is described generally as concrete pipe.
The filing of each of the affected actions followed the return in the District of New Jersey of two criminal indictments charging violations of the antitrust laws. These criminal actions, in that district, were given the numbers Cr. No. 9-66 and Cr. No. 10-66. (None of the affected civil actions were filed in the District of New Jersey.) The defendants in these criminal actions were convicted on pleas of nolo contendere.
Some of the plaintiffs in the affected civil actions are end-users of concrete pipe and some are competitors of one or more of the defendants.
The indictment in Cr. No. 9-66 described the defendants, their states of incorporation, principal place of business and short descriptive names as follows:
Name of Corporation State of Incorporation Principal Place of Business Hereinafter Referred to as
International Pipe and Ceramics Corporation Delaware East Orange Interpace New Jersey
Lock Joint Pipe Company New Jersey East Orange Lock Joint New Jersey
Kerr Concrete Pipe Company New Jersey Paterson New Jersey Kerr
Martin Marietta Corporation Maryland New York New York Martin Marietta
North Jersey Concrete Pipe Co. Inc. New Jersey Irvington New Jersey North Jersey
Interpace is the successor to the concrete pipe business formerly carried on by Lock Joint. Martin Marietta is the successor to the concrete pipe business formerly carried on by the Martin Company, a Maryland corporation, and by American-Marietta, an Illinois corporation, which merged in October 1961 to form Martin Marietta Corporation.
The product “concrete pipe” was defined, in the indictment in Cr. No. 9-66, to mean non-pressure pipe constructed of concrete, either with or without metal components, to convey water or sewage. The metal components were defined, in the same indictment, to mean steel rods, wire and mesh used in the manufacture of concrete pipe. The indictment charges that cement and metal components account for 80% of the cost of raw materials used in the manufacture of concrete pipe; that the metal components are the most costly ingredients; that over 75% of the cement and metal components were produced outside of New Jersey. In this indictment the defend[246]*246ants and their predecessors are charged with an unlawful conspiracy in restraint of interstate trade and commerce (in violation of Section 1, Title 15, U.S.C.) beginning in August 1960, and continuing thereafter until at least April 1962. This indictment further charged the alleged conspirators, including other individuals not named as formal defendants, with the following unlawful acts:
(a) submission of collusive non-competitive prices for the sale of concrete pipe in Northern New Jersey:
(b) allocation and division of orders of concrete pipe in Northern New Jersey among Martin Marietta, Kerr, North Jersey and Lock Joint; and
(c) increasing fixing and stabilizing prices at which concrete pipe was sold in Northern New Jersey.
In Cr. No. 10-66 only Interpace, Lock Joint and Martin Marietta were named as corporate defendants. The product involved in that indictment was “concrete pipe” defined as low pressure and non-pressure pipe (constructed of concrete and metal components, having rubber gaskets and steel ring joints) and low pressure concrete pipe having concrete joints and rubber gaskets. This “concrete pipe”, the indictment charges, was used to convey water, primarily for drinking and irrigation purposes, and sewage for sanitation and similar purposes. The time period of the alleged conspiracy, charged in Cr. No. 10-66, began in 1955 and continued at least until 1962. The unlawful overt acts alleged to have been committed by the conspirators are similar to those alleged in Cr. No. 9-66, supra.
In Cr. No. 10-66 the territory, in which the alleged conspiracy was designed to be effective, was the “Eastern United States” defined as all states lying east of the Rocky Mountains (except Texas, Louisiana, and Mississippi), from which is derived the description in the title “East of the Rockies.” 1
The indictment in Cr. No. 10-66 further alleged that, during the period involved, Lock Joint (predecessor of Inter-pace) and Martin Marietta were the principal manufacturers of concrete pipe in the eastern United States; that Lock Joint then had plants in New Jersey, New York, Connecticut, Maryland, South Carolina, Florida, Michigan, Illinois, Missouri, Oklahoma, Kansas, Colorado, Wyoming and Ohio; that Martin Marietta then had plants for the manufacture of concrete pipe in the following states: Alabama, Colorado, Florida, Georgia, Illinois, Indiana, Kentucky, Maryland, Michigan, Missouri, New Jersey New York, Pennsylvania and Tennessee.
At the time the motion to transfer these cases under Section 1407 was filed there were more affected civil actions (13) filed in the Northern District of Illinois than in any other district; but there were far more plaintiffs in the 6 cases in the Eastern District of Pennsylvania.2 Nevertheless counsel for the [247]*247plaintiffs in the Northern District of Illinois, and others, concede that the Eastern District of Pennsylvania is the logical transferee district. In view of the number of plaintiffs in the eastern United States, and the number of plaintiffs in the actions in the Eastern District of Pennsylvania, counsel for the plaintiffs in the Western District of Missouri agree that the Eastern District of Pennsylvania is the logical transferee district. And as stated hereinabove, counsel for the moving plaintiffs in actions in the Southern District of New York also agree that the Eastern District of Pennsylvania is the logical transferee district, if the actions are to be transferred elsewhere.
Before creation of this Panel, the CoOrdinating Committee for Multiple Litigation, with concerned trial judges, conducted hearings at Philadelphia and Chicago, as a result of which preliminary coordinated discovery was recommended to explore the existence of the relation between the cases in the several districts. Under the orders of the Honorable John Morgan Davis, United States District Judge of the Eastern District of Pennsylvania, to whom all the cases in that district have been assigned, these recommendations have been implemented and discovery is current. In some of the other districts, this discovery has been wholly or partially accomplished.
In the affected civil actions in the Eastern District of Pennsylvania and in the Southern District of New York conflicting class action requests have been made. With one dissenting opinion a class action issue in the Southern District of New York has been determined adversely to the City of New York by interlocutory decision of the district court and of a Panel of the Second Circuit Court of Appeals, decided April 10, 1969, City of New York v. International Pipe and Ceramics Corp., 410 F.2d 295.
The Common Questions of Fact
These actions involve many common questions of fact. All are based on the two criminal indictments in the District of New Jersey, one of which charged a conspiracy effective in most of the states and concerned districts east of the Rockies. The other indictment charged a conspiracy effective in the Northern District of New Jersey. It is true that different products are designated in the two indictments. But these differences do not render the proposed transfers improper. They may or may not affect the manner in which the transferee court conducts the pretrial proceedings. In re Plumbing Fixture Cases, Judicial Panel on Multidistrict Litigation, 295 F.Supp. 33.
The complaints in all the affected actions contain allegations similar to those in the indictments mentioned above. Although some of the complaints involve additional years and additional allegations not found in the indictments with respect to pressure pipe (said to be manufactured only by Interpace) and with respect to a violation of Section 2, Title 15, U.S.C., nevertheless the common conspiratorial questions of fact respecting price fixing, allocation of orders and collusive bidding, among others, remain.
Furthermore, in additional to these common conspiratorial questions of fact there are many more common questions of fact in the affected civil actions. The additional common questions of fact include, among others, the following:
(1) question of fraudulent concealment, necessary to toll the statute of limitations;
(2) the several factual questions under Rule 28, F.R.Civ.P., which must be resolved to determine the propriety of the many and conflicting class action requests; and
(3) the many economic questions of fact affecting prices in the absence of conspiracy; including, for example, methods of manufacture, prices of steel products and cement used as components, and production costs, none of which are unique local market questions.
[248]*248Counsel for the defendants, opposing transfer, argue that the criminal indictments are limited in their averments of time periods, parties, products, geographic markets and conspiracy allegations, and are not as broad as the complaints in the civil actions. One answer to these arguments is that the plaintiffs are not limited in their bases of civil actions by the particular averments of the indictments.
Treble damage antitrust actions may be maintained without an indictment and without conviction or other government proceeding. A fortiori, when there has been a government action, private treble damage civil plaintiffs are entitled to the statutory remedial assistance of the government action [such as the tolling of limitations under Section 5(b)] despite difference in time periods, conspiratorial details and parties, provided there is substantial identity of subject matter. There is such identity when the private complaint is based in whole or in part on any matter complained of in the government action. Section 16, Title 15, U.S.C. Leh v. General Petroleum Corp., 382 U.S. 54, 86 S.Ct. 203, 15 L.Ed.2d 134, l. c. 138; Minnesota Mining & Mfg. Co. v. New Jersey Wood Finishing Co., 381 U.S. 311, 85 S.Ct. 1473, 14 L.Ed.2d 405. Cf. State of Michigan v. Morton Salt Co., D.C., 259 F.Supp. 35, l. c. 55, affirmed sub. nom. Hardy Salt Co. v. State of Illinois (C.A. 8) 377 F.2d 768, cert. den. 389 U.S. 912, 88 S.Ct. 238, 19 L.Ed.2d 260. In the Leh case, supra, the Supreme Court expressly approved the “substantial identity of subject matter” rule announced in Union Carbide & Carbon Corp. v. Nisley (C.A. 10) 300 F.2d 561, l. c. 670, app. dism. sub. nom. Wade v. Union Carbide & Carbon Corp., 371 U.S. 801, 83 S.Ct. 13, 9 L.Ed.2d 46, and rejected the narrow rule of Steiner v. 20th Century-Fox Film Corp. (C.A. 9) 232 F.2d 190. The rule of the Leh case shows that the argument of defendants in these cases is not relevant and not sound.
In light of the Leh ease it would be inappropriate to sustain the defendants in their technical view that differences between the underlying indictments and the civil complaints in respect to geographic areas in which the conspiracy is operative, and in respect to time periods, conspiratorial details and parties, somehow militate against transfer under Section 1407. Genuine common questions of fact do not depend upon the limits or breadth of the indictments or convictions in any case.
Defendants urge that there are no common questions of fact in these cases because there are only local markets for delivery of concrete pipe, since the pipe can economically be delivered only a few miles beyond the point of manufacture. Assuming this to be true, the two major defendants, according to the indictments, found this to be no barrier to multi-state organization of its industrial activity in producing, selling and delivering the pipe to many “local markets”. Further, in the view of the government, the major defendants found the delivery problem no barrier to multi-state conspiratorial activities affecting a great number of local markets.3 The defendants in the criminal actions, by pleading nolo contendere, chose not to challenge this view of the government by trial on the factual issues. The plaintiffs in the civil actions have the right to raise similar questions of fact.
As in many of the instances of multi-district litigation, “small defend[249]*249ants” oppose transfer of actions in which they are defendants on special grounds of alleged excessive costs. It is by no means clear that the small defendants’ interest of overall costs would be served by denying transfer of the claims for relief against them. It is clear, however, that the transferee court can exercise its discretion in scheduling pretrial proceedings in a manner which will protect the legitimate interests of small defendants in the costs of litigation. Cf. In re Plumbing Fixture Cases, supra, 295 F.Supp. at page 34.
Except in respect to the New Mexico action, it is found that transfer of these affected actions to the Eastern District of Pennsylvania for consolidated or coordinated pretrial proceedings will be for the convenience of parties and witnesses and will promote the just and efficient conduct of such actions.
The New York Class Action Question
As stated above, in the affected actions pending in the Southern District of New York, the district court has ruled adversely on a request for an interlocutory class action determination. A panel of the Second Circuit Court of Appeals has, by a divided vote, held this interlocutory determination unappealable. Until these class action issues are no longer subject to early appellate review in the Second Circuit and no longer subject to review by extraordinary writ, including certiorari, ruling on the motion of transfer of these cases pending in the Southern District of New York should be deferred. So action will be stayed in those cases until further order of the Panel. At an appropriate time the multidistrict class action conflicts should be given special consideration by the Panel. Cf. In re Multidistrict Private Civil Treble Damage Litigation Involving Plumbing Fixtures, Judicial Panel on Multidistrict Litigation, 298 F.Supp. 484 (filed December 27, 1968).
The New Mexico Case
Because counsel agree that the New Mexico case is not a part of the alleged “East of the Rockies” conspiracy, transfer of that case should be denied.
The Colorado Cases
The affected actions in the District of Colorado differ in some respects from the other cases, but many common questions of fact remain. Those eases should be transferred because there are many common questions of fact in those cases and the remaining affected cases. Transfer should not be denied because there are additional questions of fact in the Colorado cases.
The Honorable John Morgan Davis is willing to accept transfer of any of the affected civil actions pending in districts other than the Eastern District of Pennsylvania. The United States District Court for the Eastern District of Pennsylvania has consented to the transfer of any of the affected civil actions and the assignment of any of the actions to Judge Davis, as shown by the consent attached hereto signed by Chief Judge John W. Lord, Jr., for that Court.
For the foregoing reasons, it is hereby
Ordered that all civil actions listed in the attached Schedules A and B except those pending in the District of New Mexico and in the Southern District of New York be, and they are hereby, transferred to the Eastern District of Pennsylvania pursuant to Section 1407, Title 28, U.S.C., and assigned to the Honorable John Morgan Davis, United States District Judge. It is further
Ordered that transfer under Section 1407, Title 28, U.S.C., of the civil action pending in the District of New Mexico, listed in Schedule B attached, be, and it it hereby, denied. It is further
Ordered that ruling on the transfer under Section 1407, Title 28, U.S.C., of the civil actions pending in the Southern District of New York, listed in Schedule A attached, be, and it is hereby, stayed until further order of the Panel.
