The IRS summons power is the IRS's principal compulsory investigative tool. In United States v. Clarke, 573 U.S. ___, ___, 134 S. Ct. 2361 (2014), here, the Supreme Court confirmed that the summons enforcement proceeding brought by the U.S. in a district court case against the noncomplying witness (usually the taxpayer or a party related to the taxpayer) is a summary proceeding where the IRS's prima facie showing is minimal. In the original Clarke case, the compelled parties alleged improper purposes under Powell in order to obtain an evidentiary hearing in which it could examine IRS witnesses to establish the improper purpose. At that time, most district courts summarily enforced the summonses with minimal, if any, evidentiary proceedings to explore the compelled parties' bare allegations of impropriety. The Eleventh Circuit earlier bucked that trend and held that an evidentiary proceeding was required. The Government obtained certiorari, and the Supreme Court remanded the case for further consideration under the standards it set forth in the opinion (set forth below). Upon remand, the district court summarily enforced the summonses involved. The case then went back to the Eleventh Circuit which, on March 15, sustained the district court's summary enforcement of the summons. United States v. Clarke, ___ F.3d ___, 2016 U.S. App. LEXIS 4728 (11th Cir. 2016), here. I will cut and paste and comment, as appropriate, on key parts of the Eleventh Circuit's opinion
First, the Court makes the introduction with a succinct summary of the applicable law.
The IRS's authority to investigate is extensive. See United States v. Arthur Young & Co., 465 U.S. 805, 816, 104 S. Ct. 1495, 1502 (1984). Under 26 U.S.C. § 7602(a), the IRS may issue a summons for the purpose of "ascertaining the correctness of any return, making a return where none has been made, determining the liability of any person for any internal revenue tax . . ., or collecting any such liability." See also United States v. Morse, 532 F.3d 1130, 1132 (11th Cir. 2008).
The summons authority is subject to limitations. Under Powell, the IRS must make a four-part prima facie showing to obtain enforcement of a summons from the district court: that (1) "the investigation will be conducted pursuant to a legitimate purpose," (2) "the inquiry may be relevant to the purpose," (3) "the information sought is not already within the Commissioner's possession," and (4) "the administrative steps required by the Code have been followed." United States v. Powell, 379 U.S. 48, 57-58, 85 S. Ct. 248, 255 (1964). Afterward, "the burden shifts to the party contesting the summons to disprove one of the four elements of the government's prima facie showing or convince the court that enforcement of the summons would constitute an abuse of the court's process." United States v. La Mura, 765 F.2d 974, 979-80 (11th Cir. 1985). However, a court reviewing an enforcement petition "may ask only whether the IRS issued a summons in good faith, and must eschew any broader role of 'oversee[ing] the [IRS's] determinations to investigate.'" Clarke, 573 U.S. at ___, 134 S. Ct. at 2367 (alterations in original) (quoting Powell, 379 U.S. at 56, 85 S. Ct. at 254).
Under Clarke, a taxpayer is entitled to examine an IRS agent concerning the issuance of a summons only when he can "make a showing of facts that give rise to a plausible inference of improper motive." Id. at ___, 134 S. Ct. at 2368. Examples of an improper purpose to issue a summons include harassment of the taxpayer or "any other purpose reflecting on the good faith of the particular investigation." Powell, 379 U.S. at 58, 85 S. Ct. at 255.
