The Australian Government thinks that it's good if schools have chaplains. So it’s been contracting with various organisations, funding them to provide chaplains.
(In Australia, Government schools are the legal responsibility of the State Governments. As they also think that school chaplains are a good idea, this doesn’t create a problem.)
But Mr Ron Williams wanted his children to have a secular education. He asked the High Court to stop the Australian Government from funding the chaplains at his children’s school. And, on Wednesday last, the Court did so.
