Conflict of interest and natural justice in an RFS Disciplinary hearing

Today’s question relates to the application of natural justice and conflicts of interests in NSW RFS disciplinary matters. My correspondent asks:

Can an appointed investigator of alleged allegations against a RFS volunteer be then placed as the Chairperson of the Zone Discipline Panel to make decisions on the same allegations?

The critical issue here is ‘natural justice’. One of the key elements of natural justice is that the decision maker must not have a stake in the matter and must hear from both sides and decide the issue before them without prior judgment.
