Western Australia's top judge told police that prominent Perth barrister Lloyd Rayney was the most agitated and stressed he had ever seen him when his estranged wife went missing.
Chief Justice Wayne Martin's witness statement from October 2007 was among dozens of statements made available to the media on Monday in connection to Rayney's murder trial, in which he is accused of murdering his wife, Corryn, on August 7, 2007.
In the statement, Justice Martin described Ms Rayney, a registrar at the Supreme Court, as 'extremely conscientious' and reliable, and thought it unusual she did not appear for work on August 8.
He said Rayney came to him that day and said he did not think his wife had come home the night before and asked the chief justice if he knew they had been having marital problems, to which he replied that he did not.
Justice Martin said Rayney had asked him to authorise police access to his wife's emails in the hope they might find clues.
He said he granted the access to police, but not to Rayney.
'Lloyd was extremely agitated and appeared to be under a great deal of stress,' Justice Martin said.
'I have known Lloyd for a number of years and have worked with him while at the Bar.
'I have never seen him so agitated or stressed as he was that day.'
In a second police statement, the chief justice discussed Rayney's failed attempt to become a senior counsel in 2004.
Rayney, who had worked as a senior prosecutor before becoming a defence barrister, explained in his application that he had more than 10 years' experience prosecuting in criminal trials, including more than 350 jury trials.
The prosecution alleges Rayney killed his wife at their home and then dragged her body across the front yard to her car.
He then allegedly buried her head-first in a bush grave at Kings Park before dumping her car in a nearby suburban street.
The mother of two's body was found on August 15.
The defence team has questioned the integrity of the police investigation into Ms Rayney's death.
