An inquiry into the conviction of David Harold Eastman for murdering one of Australia's top police officers has been given a start date for November.
Eastman is serving a life sentence for killing Australian Federal Police assistant commissioner Colin Winchester in 1989.
He secured the latest inquiry in 2012 after it was claimed new evidence had emerged.
The inquiry was to have started in March but has been delayed, first by problems with Eastman's legal team which all eventually stood aside and then a call by Eastman for inquiry head Justice Kevin Duggan to stand down.
The latest call was rejected in the Federal Court two weeks ago.
At a directions hearing on Tuesday Justice Duggan said he would like a start date in August, but that has been stretched out to allow Eastman's new lawyer Paul Willee to prepare for the case.
The inquiry heard key evidence from a ballistics expert has not arrived yet and the Australian Federal Police say they are having problems sorting restricted material related to organised crime.
The inquiry also heard some witnesses have been reluctant to participate.
The official start to the hearing will now be November 5.
