Aboriginal literature have shown that aboriginals around the world usually possess particular cultures, and used religion or tribal leaders to peacefully resolve conflicts or crime. Braithwaite (1999) pointed out that, we ought to use restorative justice model first to deal with crime, and then we can reduce the need to use punitive or incapacitation justice model. There are two purposes for this study: to investigate the content of Atayal traditional justice concept and to compare it with other justice models. This study used in-depth interview to collect data. Data were collected from 8 mediators or pastors or Atayal police officials working in Atayal communities. Data analysis indicates that there is no concept of "crime" in the Atayal tradition, instead a "wrong" in used. It is also found that the traditional Atayal justice is deeply influenced by the Atayal belief system of Gaga that there should be social harmony, redemption and pursuit of absolute good in the handling of crime. This study also found that there is no punitive element in Atayal concept of justice. The Atayal traditional concept of justice is partially related to Reparatory Justice and Blood Feud model. However, the Atayal traditional concept of justice is highly related to the Restorative Justice.
