MEMORANDUM AND ORDER

Sanford B. Weiss, the qui tam plaintiff under the False Claims Act, 31 U.S.C. § 232 , moves to vacate the stipulated dismissal without prejudice entered into by the United States and the defendants on April 1, 1982. For the reasons set forth below, we grant plaintiff’s motion and hereby vacate the April 1 stipulation of dismissal.

For purposes of this discussion, we adopt the Government’s statement of facts. Plaintiff Weiss was the owner-mortgager of The Park Lane, a multi-resident housing project in Monterey, California. The mortgage on the project was held by a private lender and covered by a deed of trust securing a promissory note insured by the Federal Housing Administration under the National Housing Act, 12 U.S.C. § 1715v(b). In October 1968, after Weiss fell into default, the note, deed of trust, and a chattel mortgage on the personal property located at the project were assigned to the Department of Housing and Urban Development (“HUD”). In April 1969, HUD instituted foreclosure proceedings and simultaneously became mortgagee-in-possession. In September 1971, HUD, as mortgagee-in-possession, entered into a project management contract with Gerald M. Schwartz & Company under which that company agreed to manage The Park Lane. At some point between September 1971 and September 1974, James R. Regnolds became associated with Gerald M. Schwartz & Company, which subsequently became known as Schwartz & Regnolds (hereinafter, “the management partnership”). In September 1974, a foreclosure sale was held and HUD purchased The Park Lane. Simultaneously, HUD entered into a second property management contract with the management partnership, which continued to manage the project until December 1975. At that point, Regnolds dropped out of the management partnership so that he could bid' to purchase the project from HUD. Schwartz continued to manage the project.

Subsequently, Regnolds joined with Nate Corenman to form a limited partnership called The Park Lane (hereinafter, “the purchasing partnership”). Through this partnership, Regnolds and Corenman submitted a bid to HUD for the purchase of the project. Their bid was accepted by HUD in April 1976, and the sale was completed in June 1976. After the sale was completed, Schwartz obtained Corenman’s interest in the purchasing partnership.

In October 1981, Weiss, suing on behalf of the United States, filed the instant action against Schwartz, Regnolds, Corenman, the purchasing partnership, and the management partnership pursuant to the False Claims Act, 31 U.S.C. § 232 (B). In essence, Weiss alleges in the qui tam complaint that the defendants conspired to commit and did commit various fraudulent acts to diminish the value of the project, to discourage competitive bidding, and then to purchase the project. Pursuant to 31 U.S.C. § 232 (C), the Government made an entry of appearance and assumed prosecution of the action on December 3, 1981. On April 1, 1982, the Government filed a stipulation for dismissal without prejudice. Weiss now seeks to set aside that dismissal, claiming that the Government cannot dismiss a qui tam action that it has taken over. We agree with the Government that the single issue before us is whether the Government may dismiss a qui tam action in which it has entered an appearance four months previously.

The language of the Federal False Claims Act itself, not surprisingly, is not dispositive of this issue. 31 U.S.C. § 232 (C) states in pertinent part:

The Government and defendants focus on the language above which states that, once the United States enters an appearance, it-“may proceed in all respects as if it were instituting the suit.” Plaintiff, contrariwise, focúses on the subsequent proviso which allows the informer to resume prosecution of the action if the Government has failed to act diligently within a period of six months.

As all parties admit, there is no case law directly on point to guide us on this issue. In this uncertain situation, it is clear that we must examine the relevant legislative history in search of the intent of Congress. See Train v. Colorado Public Interest Research Group, Inc., 426 U.S. 1 , 96 S.Ct. 1938 , 48 L.Ed.2d 434 (1976) (courts should examine relevant legislative history in search for intent of Congress if such examination would aid construction); Heppner v. Alyeska Pipeline Serv. Co., 665 F.2d 868 , 871 (9th Cir. 1981).

The original False Claims Act was passed in 1863 to aid the Government during the Civil War. At that time there was not yet a Federal Bureau of Investigation and the United States Attorney General’s staff was quite modest. The Department of Defense [then the War Department] had no investí-, gators to check on its various suppliers and contractors. The Government was largely dependent upon information received from private individuals concerning fraudulent claims against it. Accordingly, the False Claims Act provided for private individuals to bring suits against the perpetrators of such fraud regardless of whether the plaintiff had discovered or furnished the information relative to the fraud sued upon or simply based his action entirely upon information secured by the Government in a criminal proceeding. United States ex rel. Marcus v. Hess, 317 U.S. 537 , 63 S.Ct. 379 , 87 L.Ed. 443 (1943). Although the plaintiff was liable for his own costs and had no claim against the United States for prosecuting the action, he was entitled to one-half of the forfeiture, one-half of the damages, and all costs the court might award against the defendant should the plaintiff prevail.

By 1943, so-called “parasitic” suits (i.e., suits based solely on public or quasi-public information usually obtained from criminal indictments) had become such a problem that the Attorney General felt compelled to write to the Chairman of the Senate Judiciary Committee. In September 1943, there were approximately twenty-five informer suits pending, constituting a total demand of almost $150,000,000 — a potential recovery of $75,000,000 to the informers. According to the Attorney General, almost all of these suits were of the “parasitic” type. The Attorney General, writing earlier in March of that year, explained:

Letter of Attorney General Francis Biddle to Senator Frederick Van Nuys, March 22, 1943, 89 Cong.Rec. 7571 (Sept. 15, 1943).

The original response proposed by the House was to abolish completely qui tarn actions. The Senate declined to follow the House’s lead. Instead, the Senate was in favor of allowing qui tam actions to .survive when “based upon information, evidence, or sources not then in the possession of the United States, unless obtained from such person (bringing the suit) by the United States in the course of any investigation by a grand jury, congressional committee, or other public body, or before a United States Commission, or other proceeding instituted or conducted by it.” 89 Cong.Rec. 10845 (Dec. 17, 1943).

The bill was then referred to the Conference Committee, which substituted the language which now appears in the statute. The Conference Report stated:

89 Cong.Rec. 10845 (Dec. 17, 1943).

It is not clear how or why the Conference Committee reached the particular compromise it did. See Pettis ex rel. United States v. Morrison-Knudsen Co., 577 F.2d 668, 671 (9th Cir. 1978). For the purposes of the motion before us, however, it is significant to note that the debate was focused on whether the informer’s evidence and information had to be original (the so-called “honest” informer). There was very little discussion whether, assuming the information was original, the informer could still be precluded from prosecuting the suit even though the Government declined to prosecute. What little information can be discerned from the Congressional Record, however, indicates that the qui tana plaintiff should be allowed to take over the prosecution, if the Government has stepped aside and if the informer has proffered original information.

Consider the following colloquy between two senators during the debate over the 1943 amendments to the False Claim Act:

89 Cong.Rec. 7574 (Sept. 15, 1943).

This exchange indicates that the Senators believed an honest informer could prosecute the false claims action, even if the Government wished to dismiss the action as merit-less.

Two days later, Senator Ferguson, speaking on behalf of the Senate version, stated:

89 Cong.Rec. 7604 (Sept. 17, 1943). Granted, the bill that Senator Ferguson spoke on behalf of was not yet in its adopted form. The subsequent changes, however, addressed the issue of original versus “parasitic” information; they did not address the right of a citizen “to use his original evidence to prosecute in case the Government does not do so.”

After the Conference Committee agreed upon the current form of the statute, it was presented to the House by one of the House managers, Congressman Walter. The Congressman first discussed the effect of the statute on pending suits:

89 Cong.Rec. 10846 (Dec. 17, 1943).

He then discussed the effect of the statute on future cases:

Id. We feel that there is little difference between the reasoning implicit in the first and second paragraphs above. Congress told the Attorney General he could intervene in pending cases and that, if he later thought they did not warrant prosecution, he could drop out of the case. At that point, the private citizen was allowed to “proceed on his own.” Similarly, Congress told the Attorney General he could enter an appearance in all future cases and, if he later found them to be meritless, he could decide not to proceed. At that point, the individual citizen may “proceed on his own.” Nowhere in the Congressional Record is it indicated that the Attorney General may enter an appearance and, upon subsequently determining the case to be without merit, dismiss the case. Rather, the case becomes that of the private citizen.

Congress sought to amend the Civil War False Claims statute because it was being exploited by individuals who obtained enormous windfall damages from prosecuting “parasitic” lawsuits. There is no indication that Congress sought to give the Attorney General the power to terminate lawsuits he thought meritless if the information itself was original.

89 Cong.Rec. 10846 (Dec. 17, 1943).

While admittedly sparse, we believe the relevant legislative history gives rise to the finding that Congress intended that, assuming the inapplicability of the jurisdictional bar, the informer could pursue his claims should the Government decline to prosecute. The 1943 amendments were adopted to insure that the Government was given the opportunity to prosecute such claims, not to preclude the honest informer from his day in court.

The parties discuss the one case which appears to address the instant problem, United States ex rel. Coates v. St. Louis Clay Prod. Co., 68 F.Supp. 902 (E.D.Mo. 1946). The court in Coates explained:

Id. at 904-05 .

The Government dismisses the above language as dictum from an old and remote case. This may be true. Nevertheless, the case is important for two reasons. First, although arguably dictum, it is the only discussion in the case law of the issue before us and the conclusion reached therein coincides with the sparse discussion in the Congressional Record. Second, Mr. Coates was a well-known and well-respected informer who not only testified before the Senate Judiciary Committee during its hearings on the proposed amendments to 31 U.S.C. § 232 , but also convinced the Justice Department and the Congress that his then-pending false claims suits should be exempted from the effects of the amended statute. To this end, Congress added the following final proviso to section 232(C) almost solely so that Coates, who filed his suit prior to the 1943 amendments, could continue to prosecute his case:

We may assume, therefore, that the Eastern District of Missouri was well aware of Congress’s intent when it spoke in the Coates case. That court’s interpretation of the recently-passed statute should not simply be dismissed as remote.

The Government argues finally that public policy dictates that the Government be allowed to terminate vexatious, meritless qui tam suits which are improvidently filed against innocent defendants. We believe this argument ignores relevant legislative history. First, Congress provided its own disincentive to meritless suits by making the informer completely liable for the costs of prosecution (unless the court awarded such costs to a prevailing plaintiff). The legislative history makes clear that many Congressmen thought this was a sufficient deterring force to prevent persons from bringing unnecessary suits even without the 1943 amendments. See 89 Cong.Rec. 7611 (Sept. 17, 1943).

Second, it is absolutely clear from the congressional debates that one of Congress’s biggest fears in amending the Civil War False Claims statute was that a corrupt Attorney General or other public official might be able to thwart a legitimate investigation and prosecution of fraudulent claims. It is predominantly for this reason that the Senate rejected, the original House bill which would have completely eliminated qui tam suits. While we agree with the Government that the judiciary should always be concerned that the courts not be used as vehicles for harassment, that is true in every case, not just qui tam actions. Congress intended for the honest informer to retain his right to prosecute fraud against the Government. That right may be taken over, but it may not be taken away.

We are cognizant of language in Pettis, supra, emphasized by the defendants, to the effect that the plaintiff may not prosecute his claim if the Government is apprised of the facts and fails to act. 577 F.2d at 673 . The Pettis court, however, was speaking of the scope of the jurisdictional bar; it was not addressing the issue before this court.

However, the Pettis decision does make clear that a court should decline to proceed as soon as it becomes evident that the information on which the qui tam action is predicated was in possession of the Government before the suit was filed, even when the information has been given to the United States by the informer himself. Both the Government and the defendants have submitted briefs which indicate that this court may lack jurisdiction over the instant case on this basis. The qui tam plaintiff, however, has not responded to these allegations. Following the guidance of Pettis, therefore, we hereby inform the plaintiff, Weiss, that he has thirty (30) days from the date of the filing of this order in which to reply to these arguments of the Government and the defendants and to attempt to rebut the application of the jurisdictional bar. Upon receipt of plaintiff’s brief, the court will then decide whether a full hearing on the issue of jurisdiction is warranted.

IT IS SO ORDERED.

. There are indications that the number of informer suits may have increased further at a dramatic pace by the end of 1943. See Remarks of Congressman Walter, 89 Cong.Rec. 10846 (Dec. 17, 1943). . The district court does not have jurisdiction of a suit brought by an informer unless based on evidence and information not in the possession of the United States or its agencies or employees at the time of filing. See 31 U.S.C. § 232 (C) and discussion, supra. . [W]e spent days and days in public hearings and in conference in company with Mr. Tom Clark, the Attorney General, and others representing the Department of Justice, trying to appease a certain member or members of the Committee on the Judiciary who conscientiously, I admit, objected to the repeal of the present law in its entirety. Those efforts were made to protect honest, bona fide informers; and there are some of that class. One was a man from St. Louis, as I remember, named Coates. He had a suit against some concern in St. Louis. He appeared personally before the committee, made a fine appearance and impression, and had spent considerable money in prosecuting his case and in bringing it to issue. We exempted him; and Tom Clark assured him, in front of the full committee . . . that under the terms of the amendment now under discussion, in no case would he move to dismiss that pending suit, so that Mr. Coates could continue to prosecute the suit to a finish. Remarks of Senator Van Nuys, Chairman of Judiciary Committee, 89 Cong.Rec. 7572 (Sept. 15, 1943); see also 89 Cong.Rec. 7578 (Sept. 15, 1943), 89 Cong.Rec. 7606, 7609 (Sept. 17, 1943), and 89 Cong.Rec. 10848, 10849 (Dec. 17, 1943). . We, of course, do not mean to imply that the United States Attorney’s Office possessed other than the highest motives when it stipulated to a dismissal in the instant case. . The Pettis court also stated that “only by assuming a corrupt and enfeebled federal government” would the public benefit be served by allowing an informer to bring a private suit after the United States, being apprised of the facts, fails to act. 577 F.2d at 668 . Again, however, the court was speaking of the jurisdictional bar when it made this statement; it was not referring to the situation where an honest informer wishes to prosecute his case after the United States enters an appearance and soon thereafter stipulates to a dismissal. . While it might have been preferable for the district judge to have told appellant explicitly that he was not going to hold a hearing, and then give him another chance to produce documents or affidavits, he did not abuse his discretion in reaching his decision on the basis of the affidavits presented by the defendant in view of the appellant’s complete failure to supply anything other than conclusory allegations. 577 F.2d at 674 .
