Queensland’s chief steward Peter Chadwick admits he is becoming frustrated in his attempts to finalise an inquiry into the Queensland Derby fall more than two months ago.
Brown suffered injuries to his spine, ribs and lungs and will be out of the saddle for at least another 12 months.
New Zealand-trained Lord Arthur was euthanised on the day.
An inquiry was opened with evidence taken from several jockeys and then adjourned until a time when Brown was fit to attend
Brown and fellow jockeys Tommy Berry, Matt McGillivray and Tim Clark are expected to give evidence at the resumed inquiry.
There has been a delay with getting all four jockeys together at the one time.
Chadwick said stewards were obviously keen to resolve the issues around the fall but had hit numerous hurdles.
“The best way to describe it is a logistical nightmare but we are determined to get it done,” he said.
