United States v. Euge

Background

In 1977 the IRS began investigating a man who had not filed tax returns for 1973–1976. Agents found many bank accounts they believed were run under false names. To test whether those accounts belonged to him, the IRS issued a summons ordering him to appear and give handwriting exemplars of signatures on the accounts. The district court enforced the summons but the appeals court refused, and the government appealed to the Supreme Court.

Reasoning

The Court asked whether the tax-law summons power includes authority to require handwriting samples. The majority looked to long-standing rules that witnesses may be required to provide certain physical evidence, such as fingerprints or handwriting, and reviewed earlier cases upholding broad summons authority. It concluded that the statutory duty to “appear” and “give testimony” can include producing non-testimonial physical evidence like handwriting exemplars, and that doing so does not automatically violate the Fourth or Fifth Amendments. The Court reversed the appeals court and allowed enforcement, while noting that ordinary judicial safeguards and limits on unnecessary investigations still apply.

Real world impact

The ruling gives the IRS a clear tool to identify account holders and investigate aliases in tax probes. People summoned can still challenge the summons in court and raise defenses, and the IRS must show good faith and avoid unnecessary examinations. The decision applies to enforcement of summonses, not to unrelated final criminal trials.

Dissents or concurrances

Three Justices dissented. One argued the statute does not clearly authorize creating handwriting samples; another said forcing samples raises Fifth Amendment concerns about self-incrimination. They would limit the IRS to what Congress explicitly authorizes.
