A Seattle federal judge has dismissed a proposed consumer class action against Amazon that accused the e-commerce giant of failing to meet its 'guaranteed' delivery for some purchases. US District Judge Kymberly Evanson in Seattle ruled that the customer had not shown how Amazon’s delivery practices violated Washington’s consumer protection law. In a separate case, a US appeals court has overturned a judge's order that required Amazon to refrain from firing union supporters amid a nationwide organizing campaign at its warehouses. The Second Circuit vacated the order, stating the judge did not explain why such a broad prohibition was necessary.
