Australia's Federal court issued a landmark judgment on Monday that Standard & Poor's misled investors by giving its highest rating to derivatives that lost almost all their value in the run-up to the 2008 global economic crisis.
The Australian case marked the first time a ratings agency had faced trial over the complex financial products widely cited as one of the factors that triggered the crisis and could set a precedent for future litigation around the world.
In a strongly worded judgment, Justice Jayne Jagot said S&P and ABN Amro had deceived 12 local councils that bought the triple-A rated CPDO, or constant proportion debt obligation, notes created by the bank. The councils were assured the so-called "Rembrandt" notes bought from Australian Local Government Financial Services (LGFS) in late 2006 had a less than 1 percent chance of defaulting.
