Rayney wants to practise law again

Former prominent Perth barrister Lloyd Rayney is fighting a decision by the Legal Practice Board to cancel his certificate to practise law.

Mr Rayney has taken the matter to the State Administrative Tribunal after the board expressed concern about his behaviour shortly before his Supreme Court registrar wife, Corryn, was murdered.

The board pointed to a 2010 judgment that was made public in June in which it was found that Mr Rayney had taped conversations with his wife and deliberately disposed of recording devices when he knew police had a search warrant.

His lawyer, Martin Bennett, told AAP the review was likely to be heard in late September or early October.

Mr Rayney was acquitted in May of enlisting a surveillance expert to illegally intercept his wife's landline phone calls after a judge ruled midway through the trial that Mr Rayney had no case to answer.

Ms Rayney disappeared after her weekly bootscooting class and was found buried head-first in a shallow grave at Kings Park in August 2007.

Mr Rayney was cleared of murdering her in 2012 and a subsequent appeal was also dismissed.

He is still in the process of suing the state after senior police made allegedly defamatory comments about him a month after the mother of his two children was killed.

A cold case review of Ms Rayney's murder was launched in May.
