delivered the opinion of the Court.
Cogen, with others as codefendants, was indicted in the federal court for southern New York on a charge of conspiracy to violate the National Prohibition Act. Before the indictment, certain papers had been taken from his person without a warrant. After the indictment and before trial, he applied to that court, in the criminal case, for an,order requiring the United States Attorney to return the papers; and to suppress all evidence obtained therefrom, on the ground that the search and seizure had been in violation of his constitutional rights. The application was denied. Before the trial of the cause, Cogen sued out a writ of error from the Circuit Court of Appeals. It dismissed .the writ, holding that the order sought to be reviewed was interlocutory and hence not appealable. 24 F. (2d) 308. This Court granted a writ of certiorari.
Cogen claims that it is final, contending that his application for surrender of the papers is a collateral matter, distinct from the genera! subject of the litigation; and that the order thereon finally settled the particular controversy. He argues that, being so, it falls, like the orders in
Forgay
v.
Conrad,
It is true that the order deals with a matter which, in one respect, is deemed collateral. As was said in
Segurola
v.
United States,
It is not true that the order on such a motion deals with a matter distinct from the general subject of the litigation. Usually the main purpose of the motion for the return of papers is the suppression of evidence at the forthcoming trial of the cause. The disposition made of the motion will necessarily determine the conduct of the trial and may vitally affect the result. In essence, the motion resembles others made before or during a trial to secure or to suppress evidence, such as applications to-

suppress a deposition,
Grant Bros.
v.
United States,
It is not true that the decision on such a motion for the. return of papers necessarily settles the question of their admissibility in evidence. If the motion is denied, the objection to the admissibility as evidence is usually renewed when the paper is offered at the trial. And, although the preliminary motion was denied, the objection made at the trial to the admission of the evidence may be sustained. For as was said in
Gouled
v.
United States,
Motions for the return of papers and the suppression of evidence made in the cause in advance of the trial, under this rule of practice, must be differentiated from independent proceedings brought for a similar purpose. Where the proceeding is a plenary one, like the bill in equity in
Dowling
v.
Collins,
10 F. (2d) 62, its independent character is obvious; and the appealability of the decree therein is unaffected by the fact that the purpose of the suit is solely to influence or control the trial of a pending criminal prosecution. Applications for return of papers or other property may, however, often be made by motion or other summary proceeding, by reason of the fact that the person in possession is an officer of the court. See
United States
v.
Maresca,
Motions for the return of property, made in connection with a motion to quash a search warrant issued under the National Prohibition Act, may be independent proceedings, but are not necessarily so. By Act of October 28, 1919, c. 85, Title II, § 25, 41 Stat. 305, 315 and Espionage Act, June 15, 1917, c. 30, Title II, § 16, 40 Stat. 217, 229, Congress made specific provision, by an independent proceeding, for the vacation of a warrant wrongfully issued and for return of the property.

Dumbra
v.
United States,
Where in cases arising under the National Prohibition Act a defendant seeks to obtain, by motion in advance of trial-, return of property which was not seized under a search warrant, the interlocutory character of the order entered thereon-is ordinarily clear. 7 This is true of the order here in question. The motion was not for the return of papers seized under a search warrant. It was filed in the criminal case-after the indictment and before *228 trial. It seeks not only return of the papers, but the suppression of all evidence obtained therefrom. And such suppression of evidence appears to be its main, if not its only purpose. The appeal was properly dismissed by the Circuit Court of Appeals. .
Affirmed.

Casino,
The fact that, on the docket of the District Court, the motion to vacate the search warrant appears to have been filed in the criminal case and to have been disposed of there, has been brought to our attention through the diligence of Cogen’s counsel. But this -fact was not disclosed by the records or briefs in either of the Steele cases.
