A preliminary question is presented relating to the lack of jurisdiction of this court to entertain the appeal. Appellees urge the contention that the order directing the production of the files was a mere interlocutory order from which no appeal will lie. But the argument rests upon a misconception. The Government did not appeal from the directive of the court for the production of the files. The appeal was taken from the order vacating and setting aside the judgments and sentences in the two criminal cases. Such order was predicated upon the refusal to make the files available to the court. But the scope and effect of the order was to vacate and set aside the judgments and sentences in the two criminal cases. And an order of that kind is open to appeal by the Government. United States v. Williamson, 5 Cir., 255 F.2d 512, certiorari denied 358 U.S. 941, 79 S.Ct. 348, 3 L.Ed.2d 349.
The congressional purpose in the enactment of 28 U.S.C.A. § 2255, supra, was to provide that an attack upon a judgment and sentence in a criminal case which previously might have been made in a proceeding in habeas corpus should be made by motion filed in the court in which the sentence was imposed, unless for some reason the remedy by motion is inadequate and ineffective. The form of the attack under the statute is direct, but the scope is limited to matters which may be raised by collateral attack. A proceeding under the statute is an independent and collateral inquiry into the validity of the conviction. United States v. Hayman, 342 U.S. 205, 72 S.Ct. 263, 96 L.Ed. 232; Butler v. Looney, 10 Cir., 219 F.2d 146; Osborne v. Looney, 10 Cir., 221 F.2d 254; Simmons v. United States, 10 Cir., 230 F.2d 73, certiorari denied 351 U.S. 927, 76 S. Ct. 784, 100 L.Ed. 1457. It is not a proceeding in the original criminal prosecution but is an independent proceeding, civil in nature. Heflin v. United States, 358 U.S. 415, 79 S.Ct. 451, 3 L.Ed.2d 407.
While these proceedings initiated by the filing of motions under 28 U.S.C.A. § 2255, supra, were civil in character, the plaintiffs in them were defendants in the criminal prosecutions out of which the motions arose. And when in the course of the hearing upon the motions an effort was made to compel the production of secret files of the Government, 18 U.S.C.A. § 3500 became applicable with controlling effect. That statute was enacted soon after Jencks v. United States, 353 U.S. 657, 77 S.Ct. 1007, 1 L.Ed.2d 1103, was decided. It provides that in any criminal prosecution no statement or report in the possession of the Government which was made by a Government witness or prospective Government witness shall be the subject of subpoena, discovery, or inspection, until such witness has testified on direct examination in the trial of the case. It further provides that after a witness called by the Government has testified on direct examination, the court shall, on motion of the defendant, order the Government to produce any statement, as thereinafter defined, of the witness in the possession of the Government which relates to the subject matter to which the witness has testified. It further provides that if the entire contents of any such statement relate to the subject matter of the testimony of the witness, the court shall order it to be delivered directly to the defendant for his examination and use. It further provides that if the statement contains matter which does not relate to the subject matter of the testimony of the witness, the unrelated portion shall be excised in the manner therein specified. It further provides that if the Government elects not to comply with an order of the court to deliver to the defendant any such statement, or such portion thereof as the court may direct, the court shall strike from the record the testimony of the witness, and the trial shall proceed, unless the court in its discretion shall declare a mistrial. And it defines the term “statement” as used in the statute to mean a written statement made by the witness and signed or otherwise adopted and approved by him, or a tran
