On 2 November 2007, Pratt and the Visy group received an A$36 million fine, representing both the largest fine in Australian history and an estimated 0.75% of the Pratt fortune. Federal Court of Australia judge Justice Heerey said Pratt and his senior executives were knowingly concerned in the cartel, which involved price fixing and market sharing. ""This is the worst cartel to come before the courts in 30-plus years"", Justice Heerey said. Additionally, customers of Visy initiated claims against Visy and Amcor, including a $120 million suit by Cadbury Schweppes against Amcor.
