Sept 2 (Reuters) - Amazon.com (AMZN.O) must face a class action on behalf of hundreds of millions of U.S. consumers over claims that the online retail giant overcharged for products sold by third-party sellers, a federal judge in Seattle has ruled.

U.S. District Judge John Chun in an order unsealed on Friday certified a nationwide class involving 288 million customers and billions of transactions, marking one of the largest-ever in the United States.

The class includes buyers in the United States who purchased five or more new goods from third-party sellers on Amazon since May 26, 2017. The consumers’ 2021 lawsuit said Amazon violated antitrust law by restricting third-party sellers from offering their products for lower prices elsewhere on rival platforms while they are also for sale on Amazon.

Amazon’s policies have allowed the company to impose inflated fees on sellers, causing shoppers to pay higher prices for purchases, the lawsuit said. Amazon has denied any wrongdoing. It has already appealed Chun’s class certification order, which was first issued under seal on Aug. 6. mazon and attorneys for the consumers did not immediately respond to requests for comment.
