Leedom v. International Union of Mine, Mill & Smelter Workers

Background

A union called the International Union of Mine, Mill, and Smelter Workers filed a charge that Precision Scientific Co. refused to bargain. During the Board hearing, the company challenged the truth of an affidavit signed by an officer named Travis under the law’s non‑Communist affidavit requirement. The Board later held an administrative hearing, found Travis’s affidavit false, and ordered that the union be denied benefits under the Act until it complied. The union sued to block that order, and lower courts disagreed about whether the Board could impose that administrative penalty or whether Congress meant only criminal punishment for false affidavits.

Reasoning

The central question was whether the statute allows the labor board to investigate and strip a union of benefits when an officer’s affidavit is later shown to be false, or whether Congress provided only a criminal penalty against the guilty officer. The Court read the statutory text and the legislative history, noting the Conference Committee changed the law so that a filed affidavit would be "sufficient for the Board’s purpose" to avoid delays. The Court concluded Congress chose a single express sanction—criminal prosecution under the Criminal Code—and did not intend the Board to inquire into affidavit truth and impose decompliance that would punish union members for an officer’s false statement.

Real world impact

The decision leaves enforcement of false‑affidavit claims to criminal prosecution of officers rather than administrative suspension of unions. It protects unions from having Act benefits withheld because an officer filed a false affidavit, while preserving the Department of Justice’s role in pursuing perjury or fraud charges. The opinion cites that over 232,000 affidavits were filed and that the Board had referred 55 matters to the Justice Department, showing the rule affects many cases.
