Jeffrey Ian Thompson allegedly attempted to deliberately influence a witness to manufacture evidence in favour of Neill-Fraser. 

Neill-Fraser was convicted of the murder of her partner Bob Chappell who was last seen aboard the couple's yacht The Four Winds on Australia Day 2009. 

Her bid to launch a second appeal was granted by Justice Brett on March 20, with an appeal expected to be lodged as soon as possible.

Mr Thompson allegedly persuaded witness Stephen John Gleeson to change his version of events as to what he saw the night Mr Chappell disappeared in Sandy Bay.

Mr Thompson claimed boxes of documents seized by police in relation to this charge are professional legal documents relating to the Neill-Fraser matter.

Justice Michael Brett said it would be the most convenient to deal with the issue of legal privilege during the trial.

Director of Public Prosecutions Daryl Coates said the defence can object to the evidence the Crown will lead in the trial.

"Our position is that no privilege exists," Mr Coates said.

Justice Brett adjourned the matter until 28 June to allow Mr Thompson's defence and the Crown to prepare materials surrounding the issue of privilege. 

Justice Brett indicated a two-day hearing would follow shortly after this date.
