Jeff, the apology has no legal ramifications from what I understand from it because it was said in Parliament and anything said in Parliament can not be used in Court.
Indigenous Australians could commence litigation with or without the apology and it already has happened in the past few years. Therefore the "ethical" considerations outweigh the perceived "compensation" claim because regardless of the apology, litigation can and has been commencing.
Did you even read the article?
They didn't say that they were using the apology in court, they said that if they do NOT get compensation, more numbers will go to court to argue that their lives were ruined due to the act of government action. They were using it as a threat.
Besides, anyone who was abused while they were a ward of the state is entitled to compensaion. It's simply a legal matter.
The fact that they were taken from their parents and their heritage is abuse enough, whole lives was ruined, the majority never found their parents again, so if we get what, thousands of people going to court and taking million dollar claims, where does that leave us?
