In one alleged incident, an ACPO recalled being required to arrest people accused of murder, manslaughter, aggravated assaults, and sexual assaults, as well as attending fatal accidents and performing duties normally carried out by constables or sergeants.
The complaint alleged such practises “foster a racist culture in which ACPOs are considered less valuable than other members of the NT Police Force despite, to a large degree, being asked to do the same work”.
It also claimed structural inequities were “part of a broader culture of racism in the [force], which the commissioner has failed to take adequate steps to address”.
The complainants are seeking an apology from the NT government and the police commissioner for “unlawfully discriminating against ACPOs”, as well as financial compensation.
The lawyers said they would pursue legal action in the Federal Court if the matter cannot be resolved through mediation.
Allegations follow months of scrutiny of NT Police
The complaint comes after damaging allegations of racist behaviour within NT Police were aired at a coronial inquest examining the 2019 shooting death of Kumanjayi Walker.
The court heard mock racist awards were handed out among members of an elite policing unit, as well as evidence of racist language used in private text messages among officers.
NT Police Commissioner Michael Murphy revealed on the stand that he had known about the racist awards for six months before they were made public, but did not take action.
Last month, during a sweeping public apology to Indigenous Territorians at Garma Festival, Commissioner Murphy committed to “eliminating racism” within NT Police by developing a new “anti-racism strategy”.
While he would not comment directly on the human rights complaint, he said in a statement the force was “invested in cultural reform, and continuing to make progress for a safe workplace”.
