The death in custody of Yamatji woman Ms Dhu in WA in 2014 brought to public attention the ugly reality of law and policy that allow the jailing of those who default in payment of their fines.
Ms Dhu was picked up by police in 2014 with unpaid fines of $3622 and jailed. She was suffering from a broken rib at the time of her arrest, but a medical examination deemed her fit for custody.
Her condition worsened, but a second examination also declared her fit. While her health continued to deteriorate, police officers ignored her pleas for help until she died. An inquest into her death is presently underway.
There are many layers of injustice that play out in this case. One is the treatment of Aboriginal people in custody, in a justice system that is wracked with racism. If Ms Dhu were treated with appropriate care in custody, her life may have been saved.
Treatment of victims of domestic violence is also in issue in this case. It has been put to the inquest that Ms Dhu should not have been treated as a criminal, but as a victim of domestic violence. This too may have saved her life.
But at the root of this case, and so many other cases of incarceration of Indigenous Australians, is the issue of imprisonment for non-payment of fines.
Fines are usually levied as punishment for less serious offences that are not themselves worthy of jail. However jail may be a consequence of failing to pay a fine. For those who are able to afford the fines, jail might seem inevitable.
The WA corrective services minister, Joe Francis, has made it clear that fine defaulters are to be punished. He has proposed that the WA government garnishee offenders' welfare payments to recoup unpaid fines, and to increase jail time where they remain unpaid.
In his view, those who do not pay fines are shirking their responsibility, and many are taking what he calls the 'soft option' of spending four days in prison instead of paying their fines.
His comments fail to appreciate how fines operate to entrench disadvantage. Fines that cannot be paid are an inappropriate and discriminatory form of punishment.
"Whatever Francis may say, prison is not a 'soft option'. It is a dangerous, even life threatening, option for Aboriginal and Torres Strait Islander Australians."
There are three key problems with the way in which fines function in the criminal justice system. The first is that there are some offences that disproportionately target people who are disadvantaged in some way.
One example of an offence that disproportionately affects Indigenous people, particularly in WA, is unlicensed driving. It has been found, for example, that 40-60 per cent of Indigenous prisoners in Roebourne Regional Prison are there on driving offences.
Many Indigenous Australians do not have birth certificates and therefore cannot get a drivers licence. Others cannot afford to become licensed.
Yet those who live in remote areas often have no means of transport other than by car. When they are caught driving unlicensed, they receive a fine, and sicne many are unable to pay, they are consequently are jailed.
The circumstances of many Aboriginal people in remote WA thus makes it difficult for them to participate in the apparently mainstream activity of driving. The ultimate consequence of attempting to do so, ending up in prison, thus significantly compounds the initial disadvantage.
The comments by the WA corrective services minister Francis that there are 'those in society who don't want to have to pay or do anything for their failings' ignores the reality behind these offences, and that many are simply unable to pay their fines.
Even where the system of fines allows for offenders to negotiate based on their special circumstances, this assumes a level of literacy and regularity of habit. For example, it assumes that offenders are able to get to the court, that they are able to show up at the right time, and that they are able to engage with bureaucratic processes.
This last issue has a cultural component also, namely the confidence with which a person can deal with authority. For sections of the community that routinely experience discrimination, such as Indigenous Australians, this can be an impediment to engaging successfully with an authoritarian system.
It may not be clear just why Ms Dhu defaulted on her fines. But what we do know is that because she was an Aboriginal Australian, she was at risk of being fined, that she was at risk of being unable to pay the fine, and that being sent to prison put her at grave risk for her life.
Whatever Francis may say, prison is not a 'soft option'. Further, we know that it is a dangerous, indeed a life threatening, option for Aboriginal and Torres Strait Islander Australians.
Because of the established links between being an Indigenous Australian and being fined, unable to pay, and jailed; and because of the need to minimise incarceration of Indigenous Australians, governments must address how these offences are framed, and the appropriateness of the punishment for breach.
There are simple measures that may have kept Ms Dhu out of prison, and thus saved her life. Although Francis says that 'the punishment needs to fit the crime, not your income', there are successful models in which penalties are proportionate to income.
Ultimately however, there must be the possibility of forgiving the debt in appropriate circumstances. It must be possible, for those who are unable to pay, to wipe the slate clean. In the case of Ms Dhu, such a provision would have been the difference between life and death.
