Australian Consumer Law ss 18, 19 : McWilliam’s Wines Pty Ltd v McDonald’s System of Australia Pty Ltd: A wine company brought out a wine called “Big Mac”. McDonalds claimed that this was a breach of s 52 of the Trade Practices Act (the law preceding the Australian Consumer Law), arguing that people would be misled into thinking that the wine had some connection with McDonalds.
