Upjohn Co. v. United States: Privilege and Work Product in an IRS Summons

An IRS summons does not automatically override attorney-client privilege or attorney work product. In Upjohn Co. v. United States, 449 U.S. 383 (1981), the Supreme Court protected communications made during a company’s legal investigation and rejected the premise that work-product protection never applies in tax-summons enforcement. The decision also drew an essential boundary: Protecting a communication with counsel does not hide the underlying facts.

An internal investigation became the subject of an IRS summons

After accountants discovered questionable payments by a foreign subsidiary, Upjohn’s general counsel consulted outside counsel and senior management. Lawyers sent questionnaires to foreign managers and interviewed officers and employees to advise the company about the payments. The communications were treated as confidential. Upjohn later disclosed questionable payments in a report supplied to the Securities and Exchange Commission and the IRS. Upjohn, 449 U.S. at 386–88.

The IRS investigated the tax consequences and summoned the questionnaires and lawyers’ interview notes. Upjohn withheld those materials on privilege and work-product grounds. The district court ordered enforcement. The Sixth Circuit limited the corporate privilege to employees responsible for directing the company’s response to legal advice and held that the work-product doctrine did not apply to IRS summonses. The Supreme Court reversed and remanded. Id. at 388–89, 402.

Corporate attorney-client privilege extends beyond the control group

The Court rejected the narrow control-group approach, which limited protection to employees responsible for directing the company’s response to legal advice. Corporate lawyers often need facts known by employees who do not decide the company’s legal response. Excluding those employees can prevent counsel from obtaining informed accounts of conduct that creates legal exposure. Privilege serves both the lawyer’s advice and the client’s provision of information necessary for that advice. Upjohn, 449 U.S. at 389–93.

The holding rested on the actual investigation. Employees communicated with corporate counsel acting as counsel, at management’s direction, to obtain legal advice. The subjects fell within the employees’ corporate duties; the employees understood the legal purpose; and the communications were kept confidential. Those facts supported protection. A routine business investigation does not become privileged simply because someone copies a lawyer on a message. Id. at 394–95.

The majority declined to prescribe a universal test for every corporate communication. It also left the privilege question concerning former employees unresolved because the lower courts had not addressed it. Avoid treating the opinion as a categorical answer for former employees, mixed business-and-legal communications, or every document in an investigation folder. Id. at 386, 394 n.3, 396–97.

The facts remain discoverable even when the communication is protected

The IRS could question employees about what happened. Upjohn had provided the names of employees involved, and agents had already interviewed some. The government’s convenience in obtaining counsel’s assembled investigation did not defeat protection of the communications. At the same time, an employee could not withhold a relevant fact merely because it had been related to a lawyer. Upjohn, 449 U.S. at 395–96.

That distinction matters when organizing a summons response. Payment records, transaction dates, and firsthand observations should be analyzed separately from confidential requests for legal advice and counsel’s interview memoranda. Sending an existing accounting record to counsel does not, by itself, turn the underlying record into a protected communication. A record-by-record review is more reliable than withholding an entire file under one label.

IRS summonses and protection for attorney work product

Some notes extended beyond recording employee answers to counsel’s evaluation of those answers. The Court therefore separately addressed work product and held that the doctrine applies in IRS summons-enforcement proceedings. The government’s statutory investigative power remained subject to traditional privileges and limitations. The Court discussed Federal Rule of Civil Procedure 26(b)(3) as the work-product framework in those proceedings. Upjohn, 449 U.S. at 397–99.

The lower court had used a substantial-need and undue-hardship standard without giving adequate protection to lawyers’ mental processes. Interview notes can reveal which details counsel selected, what they considered significant, and how they connected the responses to legal issues. That material could not be compelled on the showing made here. The Supreme Court required a much stronger showing and remanded the work-product question; it did not declare such material absolutely immune in every circumstance. Id. at 399–402.

Separate preservation, production, and protection decisions

Preserve both the underlying records and the legal-investigation materials. Identify the participants, their roles, the legal purpose, whether the communication concerned corporate duties, and how confidentiality was maintained. Analyze attorney-client privilege separately from whether materials qualify as work product prepared in anticipation of litigation. Confidentiality alone does not establish either protection.

Before a production decision, counsel should also examine the governing privilege law, any disclosures, and the specific summons and enforcement procedure. Upjohn does not authorize ignoring a summons, destroying records, or treating tax liability as resolved. Its contribution is a disciplined distinction among facts, protected communications, and counsel’s work product. See Mishra X’s tax services for review of the summons and investigation record.
