A content warning for the next story, which mentions an Indigenous person who has died in custody.

International human rights lawyer Geoffrey Robertson is taking the death of an Indigenous man in custody to the United Nations.

Robertson said there was “no proper investigation" into the 2015 death of David Dungay in prison custody.

He says lodging a complaint with the UN is necessary, because unlike most advanced countries, Australia doesn’t have a bill of rights which protects the right to life.
