# Australia court alleges 3M hid harm risks for over 50 years

Australian government court documents allege 3M knew for more than five decades that its products, including PFAS chemicals, could harm human health but failed to disclose the risks. The claim is part of a broader lawsuit seeking compensation for environmental and health damage. This matters because it could set a major legal precedent for corporate accountability.
