This is an appeal by the United States from an order of the United States District Court for the District of Arizona entered on September 24, 1963, dismissing an indictment on the ground that all the evidence before the grand jury had been illegally obtained. Appellant asserts this court possesses jurisdiction to entertain this appeal under the Criminal Appeals Act, 18 U.S.C. § 3731 . The relevant portion of that section reads as follows:

Contrary to what is asserted by appellant, appellees allege that the district, court improperly entered an order dismissing the indictment at the behest of the government; that in so doing, the-district court attempted to provide the government with an unauthorized appellate review of two suppression orders.

This dispute as to the essential nature and propriety of the district court order presents a threshold question for our consideration, i. e., whether or not we possess jurisdiction to entertain this appeal. If we determine that such jurisdiction does exist, then, and only then, are-we faced with an examination of the-validity of the suppression orders.

The events leading up to the indictment of appellees are undisputed. At a. meeting on June 14, 1959, between the- Attorney General of the State of Arizona and a number of competitors of the Arizona Savings and Loan Association, it was decided that an ex parte order should be obtained appointing a receiver to exercise control over the Association, which was allegedly in perilous financial straits. The Attorney General forthwith obtained the appointment of a receiver on June 15, 1959, completely insulating the Association from the managerial control of the appellee-directors.

Late in 1959, a co-receiver of the Association, Mr. Colby, met with the local United States Attorney to inform him that an examination of the Association’s assets and documents had revealed a possible violation of federal law on the part of appellees. Pursuant to this conversation, the United States Attorney initiated an investigation made by the Federal Bureau of Investigation. This investigation resulted in a search and subsequent seizure by the federal government of all corporate and personal records within the Association. All such records were searched and seized without benefit of search warrant, court order or subpoena.

As a result of the federal investigation, a thirty-one count indictment was returned on May 25, 1962, charging each of the appellees with mail fraud and fraud by wire as proscribed by 18 U.S.C. §§ 1341 and 1343. The essence of the charges was that the appellees had improperly diverted funds and had falsely misrepresented the financial condition of the Association to its depositors, shareholders and investors. Appellees subsequently moved to suppress all matter disclosed by the F.B.I. investigation on the ground that appellees’ rights under the Fourth Amendment had been violated. This motion resulted in a court order of February 5, 1963, which denied the motion with respect to the books and records belonging to the Association on the ground that a receiver had the power to authorize a federal inspection, but granted the motion with respect to Mr. Kanan’s personal papers.

On April 11, 1963, in the course of its opinion in Stowell v. Arizona Sav. & Loan Ass’n, 93 Ariz. 310 , 380 P.2d 606 , the Arizona Supreme Court asserted that the function of the superintendent of banks as a receiver “is wholly ministerial.” ( 93 Ariz. at 311 , 380 P.2d 606 .) This state court decision related to the same receivership here involved. On the basis of this state court opinion, appellees in the present case filed a motion for reconsideration of the district court’s denial of their motion to suppress the information obtained from the Association documents and records on the ground that the receiver had no power, without a court order, to authorize the federal inspection. On August 9, 1963, the district court reversed its order of March 6, 1963, with respect to the Association records and documents, and ruled they, as well as Kanan’s personal records, were inadmissible.

On the date set for the trial, September 24, 1963, the government for the first time informed the appellees and the court that it was not prepared to proceed because “all of the evidence upon which the Indictment was based, all of the evidence which was presented to the Grand Jury was evidence which has now been suppressed by the Court’s first order suppressing the private papers, or by the last order suppressing the corporate papers.” (R.Tr. pp. 2-3.) Thereupon government counsel made the following statement:

Pursuant to this government request, and over defense objection, the court dismissed the indictment, stating:

The government subsequently filed a motion for reconsideration on October 21, 1963. This motion was denied on March 9, 1964, leading to the filing of a notice of appeal on April 6, 1964 invoking this court’s jurisdiction under 18 U.S.C. § 3731 .

The threshold jurisdictional question facing us essentially involves this basic conflict: Appellant asserts it has the statutory right to review a dismissal of an indictment under 18 U.S.C. § 3731 . Appellees, on the other hand, assert that no such right exists where the dismissal was obtained at the urging of the government and for the admitted purpose of avoiding the prohibition against appeal of non-final orders which suppress evidence. The controversy is thus put in sharp focus by two conflicting policy con siderations — in favor of appeal from dismissal of indictments (§ 3731); and against appeal from suppression orders.

Many courts have been asked to treat this jurisdictional question in factual situations at times quite similar to that of the present case. The results of those cases mark a pinnacle of ambivalence between the two policy considerations. Typifying the irresolute status of the case law is the fact that both parties in the present action rely on this court’s en banc opinion in United States v. Apex Distrib. Co., 9 Cir., 270 F.2d 747 (1959). That case involved the dismissal of indictments granted because the government refused to comply with certain pretrial discovery orders. The defendants contested the jurisdiction of this court to entertain the government appeals. After exhaustively reviewing the legislative history of § 3731, we granted defendant’s motion to dismiss, but, in so doing, used the following italicized language:

Appellees in the present case rely upon the result in Apex as conclusive support for the proposition that this court lacks jurisdiction to review the district court dismissal. Appellant, on the other hand, alludes to the language above quoted as indicative of this court’s willingness to hear an appeal where the dismissal results from a defect in the “institution of the prosecution,” and this is what the government alleges exists in the present case. Further examination of the Apex opinion is thus required in an effort to explore the meaning of the italicized language above.

In reaching the result of non jurisdiction in Apex, we relied heavily (270 F.2d pp. 756-757) upon the third circuit opinion of United States v. Pack, 247 F.2d 168 (1957), a case whose facts are even more comparable to the present case than are the facts in Apex. In Pack, vital government evidence was suppressed by the district court by a pre-trial order. The defendants thereafter did not move to dismiss the indictment, but rather requested a “speedy” trial. The government, just as in the present ease, informed the trial court that the suppression order had “virtually wiped out substantially all the Government’s evidence,” and the government urged the district court to dismiss the indictment sua sponte so that an appeal of the suppression order might be possible. The third circuit found that it was without jurisdiction to-entertain the government’s appeal, and, in so finding, it relied upon its earlier opinion in United States v. Janitz, 161 F.2d 19 , at page 21 (1947), where it had stated:

Relying as they did on their prior opinion in Janitz, the third circuit in Pack proceeded to hold:

In Apex, we expressly stated that we were “in substance” announcing the same ruling as that of the third circuit in Pack, to-wit: that “under § 3731 * * * an order is not appealable by the Government unless it is based upon an objection brought against the indictment.” 270 F.2d at 756. It therefore seems plausible and proper to draw the inference that when we used the language in Apex that un appeal was possible only where the dismissal of the indictment was “based upon a defect in the indictment or in the institution of the prosecution,” (270 F. 2d at 755), we did not have in mind a “defect” which merely reflected a suppression of vital evidence, as in Pack, or as in the present case.

Had we simply concluded our Apex decision on this note, our task in the present case would be relatively academic; we would conclude that we lack jurisdiction to entertain this appeal. The fact of the matter is, however, that we proceeded to discuss the other line of cases which permitted appeals where the suppressed evidence was so inextricably intertwined with the indictment that it could be said that the indictment had been obtained illegally. We had little difficulty in distinguishing this line of cases from the facts in Apex, where the indictments were not defective, but rather the government had merely failed to comply with a pretrial discovery order. But we neglected, at the same time, to distinguish this line of cases permitting a government appeal from the fact situation in Pack. In Pack, certainly, the suppression order was inextricably intertwined with the dismissal of the indictment; yet we announced in Apex that we were adhering to the reasoning in Pack. An attempt was made to distinguish Janitz and Pack from this contrary line of cases in the third circuit case of United States v. Wheeler, 256 F.2d 745 (3d Cir.), cert. denied 358 U.S. 873 , 79 S.Ct. 111 , 3 L.Ed.2d 103 (1958), on the ground that a difference exists between a mere order to suppress which ultimately results in dismissal of an indictment and a ruling that the indictment has been illegally obtained. The court distinguished its earlier holdings in Janitz and Pack in the following manner:

From this language of the third circuit in the Wheeler case, we believe that had they been faced with the facts of the present case, where the dismissal was entered because of the government’s inability to prosecute, and, coneededly, as a device for obtaining appellate review, they would have followed Janitz and Pack and concluded that they were without jurisdiction to entertain the appeal.

We must recognize, of course, that subsequent eases have read Wheeler more expansively, authorizing the exercise of jurisdiction in cases where the suppression order is the basis of the indictment dismissal. The most recent such use of Wheeler was by the second circuit in United States v. Tane, 329 F.2d 848 (1964). That case involved a dismissal of an indictment after evidence had been suppressed on a pre-trial motion because of violations of the Federal Communications Act, 47 U.S.C. § 605 . The court relied upon § 3731 as authority to entertain the appeal. It stated:

The Tane case can be distinguished from the present case on the ground that in the present case it was the government, not the defendant, which initiated the dismissal of the indictment. Whether this additional factor might have altered the decision of the second circuit • in Tane is a question we do not feel compelled either to explore or determine. We rather conclude that we are acting consistently with our own opinion in Apex, and with the third circuit opinions in Janitz, Pack and Wheeler, by holding that 18 U.S.C. § 3731 did not intend to confer jurisdiction on a court of appeals to review a dismissal of an indictment where that dismissal was secured at the insistence of the government, where the government felt unable to proceed to trial because of an insufficiency of evidence, and where the government admittedly sought through an indictment dismissal to obtain review of a district court suppression order.

The Criminal Appeals Act has always been considered subject to strict construction, for appeals by the government in criminal cases “are something unusual, exceptional, not favored.” Carroll v. United States, 354 U.S. 394 , 77 S.Ct. 1332 (1957). With this principle in mind, we hold that the facts of the present case do not warrant an extension of the government’s right to appeal under 18 U.S.C. § 3731 .

The motions are therefore granted and the appeal is dismissed for lack of jurisdiction.

. For purposes of this opinion, the two suppression orders have been treated in a consolidated manner. Had we treated them separately, the government would have faced an added burden to show that each order was inextricably intertwined with the dismissal of the indictment. . That the defendant moved for dismissal of the indictment in Tane, see 329 F.2d at 849 . It is also worthy of note that, in the present case, not only did the defendants not move for dismissal of the indictment, but also two of the appel-lees, Elbell and Wolfe, as non-officers of the Association, did not even possess standing to join in the motion to suppress. Furthermore, by virtue of the Supreme Court reasoning in Lawn v. United States, 355 U.S. 339 , 78 S.Ct. 311 , 2 L.Ed.2d 321 (1958) and Costello v. United States, 350 U.S. 359 , 76 S.Ct 406 , 100 L.Ed. 397 (1956), had the ap-pellees moved for dismissal of the indictment, their motion probably would have been denied because of the prohibition against “going behind” an indictment to challenge its validity by reason of the character of the evidence before the grand jury. And, as appellees emphasized in oral argument, beyond a mention of two diaries seen by a witness (later called by appellees) when she testified before the grand jury, neither appellant nor appellees, nor the trial judge can know just what evidence was introduced before the grand jury. We can speculate, as does appellant, that it must have been either that which was later suppressed, or that which sprang from that which was suppressed, but we have no method of accurately determining this point. Hence we cannot say either as a matter of fact or law, that only the suppressed evidence resulted in the indictments.
