I'll add a little colour: the Australian High Court is the country's highest court so American's should read this as very rapid submission Australia's equivalent of the US Supreme Court.
Once again I had the best seats in the house to watch Andrew blast through the research for this filing and then submit it in 24 hours. This isn't even our case, but it's such a bit oversight and it would be so beneficial to us if Facebook lose this appeal, it was well worth it for Andrew to take the time to research, write and file this.
