Costco filed a recent lawsuit seeking a full refund if the Supreme Court strikes down the bulk of President Trump`s tariffs.

The big-box warehouser joins dozens of companies that have lined up for refunds in recent weeks as the high court`s decision looms.

Like the others, Costco said it needed to file its own case because it is "not guaranteed a refund for those unlawfully collected tariffs in the absence of their own judgment and judicial relief."

The company is represented by law firm Crowell & Moring, which has brought roughly 50 near-identical lawsuits on behalf of separate companies.

The list of companies that have recently sued include players in the auto industry - such as Kawasaki and several corporations part of the Toyota Group - food companies such as Bumble Bee Foods, and the cosmetics business Revlon. Even board game company Smirk & Dagger Games filed.

It comes as the Supreme Court prepares a decision on whether Trump can invoke a 1970s emergency powers law, the International Emergency Economic Powers Act (IEEPA), to justify his sweeping tariffs. The justices heard oral arguments last month.

The IEEPA provides the president unilateral authority to "regulate" importation when necessary to combat a national emergency, but a group of Democratic-led states and small businesses are attempting to convince the court that Trump has stretched the law too far.

Trump has invoked the IEEPA dating back to February, when he first declared a fentanyl emergency to impose levies on Canada, China and Mexico. The president has since declared a trade deficit emergency to implement his "reciprocal" tariffs on trading partners across the globe.
