A federal court has concluded that states have standing to challenge the U.S. Equal Employment Opportunity Commission's rule implementing the Pregnant Workers Fairness Act, clearing a key procedural hurdle in the ongoing legal fight over the agency's regulations.

The decision means the case can now move forward on the merits, keeping in play questions about how much of the EEOC's interpretation of the PWFA employers will ultimately have to follow. For HR teams, the litigation touches directly on accommodation obligations — the people-process decisions around evaluating accommodation requests, engaging in the interactive process, and documenting outcomes for pregnant and postpartum workers.

The PWFA itself, passed with bipartisan support and effective June 27, 2023, requires covered employers with 15 or more employees to provide reasonable accommodations for known limitations related to pregnancy, childbirth, or related medical conditions, unless the accommodation imposes an undue hardship. The statute remains federal law regardless of the litigation's outcome. What the states are challenging is the EEOC's implementing rule — the regulation that spells out how the agency interprets the statute's scope.

At the center of the dispute is the question of standing: whether state governments can show a concrete injury sufficient to sue over a federal agency rule. The court's conclusion that they can removes the threshold defense that could have ended the case before it began.

For employers, the practical effect is continued regulatory uncertainty layered on top of a compliance obligation that is already in force. The EEOC's rule took effect June 18, 2024, and the agency has treated its provisions as binding guidance in enforcement actions since then. HR leaders have had to build accommodation workflows — request intake, medical documentation standards, undue hardship analysis — around the regulation's terms even as its legal fate remains unresolved.

The litigation also carries broader significance for administrative-law watchers. Challenges to agency rules on standing grounds have become a common first line of defense in employment-law cases, and a decision allowing states to proceed adds to the body of precedent determining who can bring such suits. How courts draw those lines affects not just the PWFA rule but future challenges to EEOC, U.S. Department of Labor, and other agency actions affecting the workplace.

Employers should not read the ruling as a reason to pause compliance. The underlying statute is untouched by the lawsuit, and the EEOC continues to enforce the PWFA. The safest operating posture remains full adherence to the existing rule while monitoring the case as it proceeds to a merits decision — an outcome that will determine which parts of the regulation survive and how much interpretive room employers ultimately have.
