Shareholder Portia McCollum filed a lawsuit in Manhattan federal court on Tuesday, accusing Estée Lauder's Asia travel retail sales channel of relying on a "pervasive, prohibited grey market reselling industry" and duty-free daigou. The lawsuit alleges that Estée Lauder knowingly supplied products to daigou to boost sales while illegally concealing its dependence on them. McCollum is seeking compensation from board members for company losses and governance reforms. Estée Lauder previously paid $210 million to settle similar allegations.
