In 2012, Australia implemented tough anti-tobacco regulations, requiring that all cigarettes be sold in plain, logo-free brown packages dominated by health warnings. Philip Morris Asia filed suit, claiming that this violated its intellectual-property rights and would damage its investments. The company sued Australia in domestic court and lost.
But it had another card to play. In 1993, Australia had signed a free-trade agreement with Hong Kong, where Philip Morris Asia is based. That agreement included provisions protecting foreign investors from unfair treatment. So the company sued under that deal, claiming that the new law violated the investor-protection provisions. It asked for the regulations to be discontinued, and for billions in compensation.
