The U.S. Department of Labor’s (DOL) newly finalized rule on labor union financial reporting is already facing legal scrutiny. On June 10, 2026, the American Federation of Labor and Congress of Industrial Organizations (AFL-CIO) filed a lawsuit in the U.S. District Court for the District of Columbia challenging the rule and its implementation timeline.
The filing marks the first formal challenge to the DOL’s Office of Labor-Management Standards (OLMS), which issued a final rule on June 1, 2026, updating the Labor Organization Annual Financial Reports. With the rule set to take effect July 1, 2026, the lawsuit introduces uncertainty for labor organizations preparing to comply with expanded reporting requirements.
What the Lawsuit Challenges
The AFL-CIO’s complaint, brought under the Administrative Procedure Act (APA), seeks to block and ultimately overturn the final rule. The organization states that both the substance of the rule and the process used to finalize it raise concerns, including the potential burden on unions without sufficient notice or justification.
The lawsuit asks the court to set aside the rule, delay its effective date and prevent enforcement while the legal challenge proceeds.
A Brief Recap of the Final Rule
The final rule amends financial reporting requirements under Title II of the Labor-Management Reporting and Disclosure Act (LMRDA). It introduces major changes effective July 1, 2026, 30 days after issuance:
- Revisions to Form LM-2:The rule changes tracking requirements for unions with annual gross receipts between $350,000 and $40 million, requiring detailed subcategorization of expenditures, such as splitting “representational activities” into “contract negotiation” and “organizing.” It also requires certain expenses, including common-carrier and lodging expenses paid directly by the union, to be itemized and attributed to individual employees.
- New Form LM-2 long form:A new, extensive reporting form applies to larger labor organizations with gross annual receipts of $40 million or more. The form includes 11 additional schedules and affects approximately 104 labor organizations, including the AFL-CIO.
Why the AFL-CIO Filed the Lawsuit
The AFL-CIO’s complaint centers on how the rule was developed, finalized and scheduled for implementation. The organization says that the changes impose substantial new requirements without providing unions enough time or opportunity to prepare.
Key points behind the challenge include:
- Limited notice and transparency:According to the complaint, the significant changes originated in October 2020 but were formally withdrawn by the DOL in March 2021. When the agency issued a new notice of proposed rulemaking in July 2025, it focused on narrower filing thresholds and did not indicate that the broader 2020 changes were still being considered.
- Compressed implementation timeline:With only 30 days’ notice, approximately 600 labor organizations with July 1 fiscal years must quickly retool their accounting and recordkeeping systems to capture data in real time. Without sufficient lead time, many may face operational disruption or the burdensome task of retroactively reclassifying large volumes of transactions.
- Changed circumstances:The AFL-CIO notes that since the original 2020 comment period, cyber threats targeting sensitive vendor data have increased, and the legal landscape has shifted following a 2021 Supreme Court decision in Americans for Prosperity Foundation v. Bonta. Labor unions were not given an opportunity to comment on these developments.
Legal Arguments Raised in the Complaint
The complaint raises legal challenges that focus on both procedural and substantive issues:
- Procedural concerns: The DOL is described as not having fully provided adequate notice and opportunity for public comment by relying on a previously withdrawn proposal.
- Timing concerns: The 30-day implementation window is described as challenging given the practical realities of compliance.
- Substantive concerns: The reporting requirements are characterized as overly burdensome and based on assumptions about costs and benefits that the plaintiff questions.
- Statutory authority concerns: The lawsuit states that certain disclosure requirements may exceed the authority granted to the DOL under the LMRDA.
What the AFL-CIO Is Seeking
As part of the lawsuit, the AFL-CIO is requesting a preliminary injunction to postpone the rule’s July 1, 2026, effective date. The organization is also asking the court to declare the rule invalid, vacate it entirely and award legal fees.
What This Means for Labor Organizations
The filing introduces uncertainty at a critical time for labor organizations. While the lawsuit seeks to delay implementation, there is no guarantee that the court will act before the July 1 effective date.
Organizations should evaluate their current reporting processes, identify potential gaps and consider whether existing systems can support the level of detail required under the DOL final rule. Even if the rule is ultimately modified or postponed, the direction of change suggests increased scrutiny and more detailed reporting expectations.
