Amazon broke consumer protection law by collecting Prime subscribers’ billing details before disclosing service terms, a federal judge ruled Wednesday, giving the Federal Trade Commission (FTC) a partial victory.

The case accuses Amazon of using deceptive tactics to boost Prime signups and blocking millions of cancellation attempts with complex methods.

The judge also ruled that two Amazon executives could be held liable if the FTC proves its claims at trial.

Amazon argued it did nothing wrong, but the ruling bars it from claiming Prime signups fall outside the Restore Online Shoppers Confidence Act (ROSCA).

The FTC alleges tens of millions of customers were enrolled without consent. The decision strengthens the agency’s push to hold Amazon accountable.
