Andrea Byers v. IRS, 963 F.3d 548

IRS Agent Joseph Conroy issued third‑party summonses to four financial institutions (Chase, Bank of America, SunAmerica Trust, Pershing) seeking Andrea Byers’s financial records (2007–2018) and related entity records; Byers was notified and told she was under investigation for possible violations of 26 U.S.C. §§ 6700 and 6701.
Byers refused an IRS interview and a direct document request, then filed petitions to quash the four third‑party summonses; the government moved to dismiss those petitions and to enforce the summonses.
The district court held a hearing, granted the government’s motion in an oral ruling, entered judgment dismissing Byers’s petitions with prejudice, and Byers appealed to the Sixth Circuit.
The principal legal question was whether § 7609(f)’s “reasonable basis” requirement (expressly imposed for John‑Doe summonses) also applies to third‑party summonses that identify a named taxpayer, and whether the IRS satisfied the Powell prima‑facie showing and Byers met her burden to show abuse of process.
The Sixth Circuit affirmed: § 7609(f) is limited to John‑Doe (unnamed) summonses; the IRS’s agent declaration satisfied the Powell factors; Byers failed to demonstrate abuse of process.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether § 7609(f)’s “reasonable basis” requirement applies to third‑party summonses naming a taxpayer	Byers: § 7609(f)’s reasonable‑basis protection should apply equally because privacy risks are similar	U.S.: § 7609(f) expressly targets John‑Doe (unnamed) summonses; Congress omitted the requirement for named targets	Court: Rejected Byers — § 7609(f) applies only to John‑Doe summonses; no reasonable‑basis precondition for named third‑party summonses
Whether the government made the Powell prima‑facie showing (legitimate purpose, relevance, not already in IRS possession, procedural compliance)	Byers: Agent’s declaration was insufficient; government failed one or more Powell prongs	U.S.: Agent Conroy’s sworn declaration establishes legitimate purpose, relevance, lack of possession, and compliance	Court: Government met the minimal Powell showing based on the agent’s declaration
Whether Byers demonstrated abuse of process to defeat enforcement	Byers: Investigation is improper, harassing, and lacks disclosed basis — warrants quash	U.S.: No evidence of improper motive; petitioner bears heavy burden and offered only conclusory assertions	Court: Byers failed to meet heavy burden; no abuse of process shown
