Amazon's NLRB Challenge Dismissed, Deepening Circuit Split
In a significant legal development, a U.S. appeals court on Monday, December 29, 2025, ruled it could not hear Amazon.com's (AMZN) legal challenge to the structure of the National Labor Relations Board (NLRB). This decision further deepens a split among U.S. circuit courts, as it contrasts with a recent ruling by a different court that sided with Elon Musk's SpaceX in a case raising similar constitutional claims against the NLRB.
The specific court involved, the Fifth U.S. Circuit Court of Appeals, dismissed Amazon's (AMZN) appeal for lack of subject-matter jurisdiction. The appeals court found that Amazon (AMZN) had not acted diligently in seeking expedited relief for its motion for injunctive relief from two administrative proceedings before the NLRB.
Amazon's (AMZN) challenge stemmed from an NLRB case concerning a landmark union election win by the Amazon Labor Union (ALU) at its Staten Island, New York, fulfillment center. The company had argued that the structure of the NLRB proceedings violated the U.S. Constitution. The appeals court's decision, rooted in Amazon's (AMZN) lack of diligence in seeking expedited relief, effectively prevented the company from challenging a lower court's perceived "constructive denial" of its preliminary injunction petition. This ruling underscores the ongoing legal complexities surrounding labor relations and the regulatory authority of the NLRB in the United States.
