I can not tell you who they are but HRNSW have changed the goal post with this already by having an investigative steward in Reid Sanders working interdependently of the stewards that will hear the case, which I am sure you are aware is different to the normal way stewards inquiries are handled in all codes in Australia.
Further they have appointed a totally independent panel of three stewards to hear the cases one of which is a retired judge again to presumably assure no issues with procedural fairness or natural justice, also when the names were released including Sarina. HRNSW made it clear they would not progress until getting independent legal advice.
Every decision made by them so far has been done to give them a greater chance of conviction and I think is is fair to assume they only proceeded today on that advice.
