Alan K. and Kathryn Stuart (taxpayers) appeal from the district court's1 order directing various bank officials to comply with Internal Revenue Service (IRS) summonses for bank records pertaining to taxpayers' financial affairs. We affirm.

On March 10, 1978 IRS Special Agent Charles D. Huckabee filed the instant petitions to enforce IRS summonses against officials of three Arkansas banks. The summonses sought records relating to taxpayers' tax liability for the years 1973-1976. Taxpayers sought, and were granted, leave to intervene. By orders dated April 6, 1978 the court enforced the summonses. Taxpayers timely appealed and contend that the court erred in enforcing the summonses.

First, taxpayers contend that the summonses were improperly issued because there is no showing that the IRS knew of any tax liability incurred by taxpayers. There is, however, no requirement that there be any knowledge of a tax liability or probable cause to believe one exists before a summons may issue. See, e. g., United States v. Bisceglia, 420 U.S. 141, 146, 95 S. Ct. 915, 43 L. Ed. 2d 88 (1975); United States v. Powell, 379 U.S. 48, 51, 85 S. Ct. 248, 13 L. Ed. 2d 112 (1964).

Second, taxpayers argue that compelling production of the bank records violates their fifth amendment right to be free from compulsory self-incrimination. They rely on Boyd v. United States, 116 U.S. 616, 6 S. Ct. 524, 532, 29 L. Ed. 746 (1886). In Boyd, the Court said that "any forcible and compulsory extortion of a man's own testimony or of his private papers to be used as evidence to convict him of crime" violated the fourth and fifth amendments. Id. at 630, 6 S. Ct. 524. Even assuming the continued validity of Boyd,2 the Supreme Court has made it clear that Boyd does not apply unless the summoned records are, at least, possessed by the party challenging the subpoena. See Couch v. United States, 409 U.S. 322, 330-31, 93 S. Ct. 611, 34 L. Ed. 2d 548 (1973). Here, taxpayers did not possess the records in question.

Recent cases have made it clear that an IRS summons directed to a third-party bank does not violate the fourth amendment rights of a depositor under investigation. See United States v. Miller, 425 U.S. 435, 443-44, 96 S. Ct. 1619, 48 L. Ed. 2d 71 (1976). In addition, such a summons does not violate any fifth amendment right of a taxpayer, because it compels no testimony from him. See Couch v. United States, supra, 409 U.S. at 328-29, 336, 93 S. Ct. 611. Cf. Fisher v. United States, 425 U.S. 391, 409, 96 S. Ct. 1569, 48 L. Ed. 2d 39 (1976) (subpoena served on taxpayer requiring production of accountant's workpapers; no fifth amendment violation).3

Judicial enforcement of an IRS summons is proper only if the summons is issued in good faith, before the IRS has abandoned in an institutional sense civil tax determination or collection purposes, and prior to any recommendation by the IRS to the Department of Justice for criminal prosecution. United States v. LaSalle Nat'l Bank, 437 U.S. 298, 318, 98 S. Ct. 2357, 2368, 57 L. Ed. 2d 221 (1978); United States v. Schutterle, 586 F.2d 1201 1203 (8th Cir. 1978). Taxpayers do not allege that these prerequisites were not met here.

Accordingly, the order of the district court is affirmed.
