mistreatment, urging his officers to treat Aboriginal people the same as they would a person of another race or background. Attorney-General for Western Australia, John Quigley, said in June 2020 that there was "systematic discrimination" against Indigenous Australians in the Western Australian justice system. Statistically, Indigenous people were far more likely to be stopped and questioned by police than non-Indigenous, more likely to be arrested if charged by police and less likely to get bail. Imprisonment of Indigenous people in WA was 4.1 per cent, compared with 2.6 nationally. The number of Indigenous adults going to prison, and young people being held in detention was still increasing, although the rate of imprisonment had slowed. He said that legislative reforms were being planned. WA has a higher number of Aboriginal deaths in custody since 1991 than any other state or territory.

These findings were substantially upheld and vindicated by an appeal bench of three judges who unanimously dismissed the prosecutors' appeal, and upheld the trial judge's analysis and verdict. An April 2014 report of the Western Australian Crimes and Corruption Commission cleared two police officers of any serious misconduct in the Corryn Rayney murder investigation. Their behaviour in threatening a female lawyer had been described as ranging from "inappropriate to reprehensible" by the trial judge. A second matter reviewed by the CCC related to "attempts by
