delivered the opinion of the Court.
Federal Rule of Criminal Procedure 6(e)(2) prohibits public disclosure by Government attorneys of “matters occurring before the grand jury” except in certain specified circumstances. This case presents the question whether a district court order denying a criminal defendant’s motion to dismiss an indictment for an alleged violation of Rule 6(e) is immediately appealable.
I
On January 23, 1987, a federal grand jury in the Western District of New York returned an indictment against petitioners Midland Asphalt Corporation, a business engaged in the sale of liquid bituminous material used to resurface roads, and Albert C. Litteer, Midland’s president and part owner. The indictment alleged that they had violated § 1 of the Sherman Act, 26 Stat. 209, as amended, 15 U. S. C. § 1, by conspiring with other unindicted persons to allocate contracts and to submit collusive bids to the State of New York and certain counties in western New York. On July 21, 1987, petitioners moved to dismiss the indictment on grounds which included an alleged violation by federal prosecutors of Rule 6(e)(2).
Petitioners’ Rule 6(e) allegations arose from the following facts: When the grand jury that ultimately returned the Sherman Act indictment was sitting, Midland and another company under investigation brought suit seeking to have the Government pay for the cost of compliance with grand jury subpoenas. In re Grand Jury Subpoenas to Midland Asphalt Corp. and Krantz Asphalt Co., Civ. No. 85-633E (WDNY, Feb. 12, 1985) (In re Grand Jury Subpoenas). In *796 that action Midland filed a motion asking that the District Court compel the Government to retain its rough and final notes of witness interviews. In response, the Government filed a memorandum in which it agreed to retain rough notes and final reports prepared by prosecutors and other Government personnel during its investigation of the western New York road-paving business. Approximately one year later, the defendants in a separate criminal case, also involving allegations of asphalt contract bid rigging in western New York State, United States v. Allegany Bitumens, Inc., Crim. No. 86-59C (WDNY, Apr. 14, 1986), filed a similar motion to require the Government to preserve its interview notes. Again the Government filed a memorandum agreeing to do so, noting that it had already made such a commitment to the District Court, and attaching a copy of its earlier memorandum in the In re Grand Jury Subpoenas case.
Petitioners’ motion to dismiss the indictment in the present case alleged that the Government’s filing, in Allegany Bitumens, of its memorandum from the In re Grand Jury Subpoenas case, publicly “disclose[d] matters occurring before the grand jury” in violation of Rule 6(e)(2). Specifically, the motion alleged that the memorandum disclosed the nature and focus of the investigation, the name of a grand jury witness, and the fact that the witness was to testify as an individual and not as a document custodian for Midland. Finding that the prosecution had not violated Rule 6(e)(2), the District Court denied petitioners’ motion to dismiss the indictment.
On appeal in the Court of Appeals for the Second Circuit, the Government moved to dismiss for lack of jurisdiction, contending that the District Court’s order declining to dismiss the indictment was not a “final decision” under 28 U. S. C. §1291. Petitioners responded that this Court’s decision in

In the Judiciary Act of 1789, 1 Stat. 73, the First Congress established the principle that only “final judgments and decrees” of the federal district courts may be reviewed on appeal.

at 84. The statute has changed little since then: 28 U. S. C. § 1291 today provides that federal courts of appeals “shall have jurisdiction of appeals from all final decisions of the district courts . . . except where a direct review may be had in the Supreme Court.” For purposes of this provision, a final judgment is normally deemed not to have occurred “until there has been a decision by the District Court that ‘ends the litigation on the merits and leaves nothing for the court to do but execute the judgment.’”

v.
Boyle,
We have little difficulty concluding that an order denying a motion to dismiss an indictment for an alleged violation of Rule 6(e) does not satisfy our “stringent conditions for qualification as an immediately appealable collateral order.”
Flanagan, supra,
at 270. Whether a violation of Rule 6(e) will be reviewable on appeal following conviction, as the Court of Appeals below held,
Petitioners attempt to avoid this reasoning by suggesting that orders of this sort, even if theoretically reviewable after conviction, are “effectively unreviewable,” Coopers & Lybrand, supra, at 468, once trial has been held, because they pertain to a right “the . . . practical value of which [is] destroyed if it [is] not vindicated before trial,” MacDonald, supra, at 860 — namely, the right not merely not to be convicted, but not to be tried at all “on an indictment returned by a grand jury whose decision to indict was substantially influenced by the government’s violation of 6(e).” Brief for Petitioner 24. We do not agree. It is true that deprivation of the right not to be tried satisfies the Coopers & Lybrand *801 requirement of being “effectively unreviewable on appeal from a final judgment.” See Abney v. United States, supra; Helstoski v. Meanor, supra. One must be careful, however, not to play word games with the concept of a “right not to be tried.” In one sense, any legal rule can be said to give rise to a “right not to be tried” if failure to observe it requires the trial court to dismiss the indictment or terminate the trial. But that is assuredly not the sense relevant for purposes of the exception to the final judgment rule.
“Certainly, the fact that this Court has held dismissal of the indictment to be the proper remedy when the Sixth Amendment right to a speedy trial has been violated . . . does not mean that a defendant enjoys a ‘right not to be tried’ which must be safeguarded by interlocutory appellate review. Dismissal of the indictment is the proper sanction when a, defendant has been granted immunity from prosecution, when his indictment is defective, or, usually, when the only evidence against him was seized in violation of the Fourth Amendment. Obviously, however, this has not led the Court to conclude that such defendants can pursue interlocutory appeals.” MacDonald, supra, at 860, n. 7.
There is a “crucial distinction between a right not to be tried and a right whose remedy requires the dismissal of charges.”

The text of Rule 6(e) contains no hint that a governmental violation of its prescriptions gives rise to a right not to stand trial. To be sure, we held last Term in

v.
United States,
As for the Grand Jury Clause of the Fifth Amendment, that reads in relevant part as follows: “No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury.” That does indeed confer a right not
to he
tried (in the pertinent sense) when there is no grand jury indictment. Undoubtedly the common-law protections traditionally associated with the grand jury attach to the grand jury required by this provision — including the requisite secrecy of grand jury proceedings. But that is far from saying that every violation of those protections, like the lack of a grand jury indictment itself, gives rise to a right not to be tried. We have held that even the grand jury’s violation of the defendant’s right against self-incrimination does not trigger the Grand Jury Clause’s “right not to be tried.”

Affirmed.
Notes
The Court of Appeals for the Ninth Circuit has read
Mechanik
to forbid postconviction review of alleged violations of Rule 6(e), and accordingly has held that district court orders denying motions to dismiss indictments for violations of the Rule are immediately appealable under the collateral order doctrine.
