against the defendant is filed in district Fed. R. Crim. Pro. 5. In addition, Rule 5.1 provides: PRELIMINARY EXAMINATION If (a) Probable Cause of Finding. from the evidence it appears that there is probable cause to believe that an offense has been committed and that the defendant committed it, the federal magistrate shall forthwith hold him to answer in district court. The finding of probable cause may be based upon hearsay evidence in whole or in part. The defendant may cross-examine witnesses against him and may introduce evidence in his own behalf. Objections to evidence on the ground that it was acquired by unlawful means are not properly made at the preliminary examination. Motions to suppress must be made to the trial court as provided in Rule 12. (b) Discharge of Defendant. If from the evidence it appears that there is no probable cause to believe that an offense has been committed or that the defendant committed it, the federal magistrate shall dismiss the complaint and discharge the defendant. The discharge of the defendant shall not preclude the government from instituting a subsequent prosecution for the same offense. (c) Records. After concluding the proceeding the federal magistrate shall transmit forthwith to the clerk of the district court all papers in the proceeding. The magistrate shall promptly make or cause to be made a record or (1) On timely application to a federal magistrate, the attorney for a (2) On application of a defendant Fed. R. Crim. Pro. 5.1.

Title II of the Omnibus Crime Control Act and Safe Streets Act of 1968, 18 U.S.C. S 3501 (1976), purports to repeal the McNabb-Mallory rule; in light of Miranda v. Arizona, 384 U.S..436 (1966), however, the constitutional effect of this repeal is questionable. The Senate Judiciary Report noted that this subsection "is not intended to require the dismissal of the extradition proceedings solely on the ground that the fugitive arrested for extradition was taken without unnecessary delay before a judge or magistrate later determined not to be the 'nearest' one." 8. Senate Judiciary Report on S. 1940, supra note 15, at 149. Probable cause for arrest in an extradition proceeding is required according to the statement in Collins v. Loisel, 259 U.S. 309 (1925), that the magistrate is to determine whether or not there is "competent legal evidence which, according to the law of [the state wherein the relator is found], would justify his apprehension and commitment for trial if the crime had been committed in that state."
