Former premier Brian Burke and a stock broker have faced court on insider trading charges.
Mr Burke and David John Massey, who it is understood worked for prominent stockbroking firm Patersons Securities, have each been charged with four counts of insider trading.
Mr Burke and Mr Massey made their first appearance on the charges in the Perth Magistrate's Court this morning where they were not required to plead to the charges.
Mr Burke's defence lawyer Stephen Leminos said the case was "something that's very long in the tooth" as the offences were alleged to have occurred six years ago.
The matters may be heard in the Supreme Court.
It is understood the charges arose from the recording of Mr Burkeâ€™s telephone calls by the Corruption and Crime Commission and the calls were passed on to Federal authorities.
As revealed in The West Australian last month, they were laid on the eve of the start of Mr Burke's most recent trial on a charge of disclosing official secrets.
It the latest legal battle for the former premier who had thought his most recent trial was the last of the CCC matters against him.
It is understood the insider trading allegations levelled against Mr Burke and Mr Massey, who has been charged with aiding and abetting the former premier, relate to shares in a company known as Amcom.
Mr Burke previously indicated to The West Australian that he intended to fight the latest charges against him. He declined to comment when leaving court this morning.
Outside court, Mr Massey's lawyer Mark De Kerloy said they would "have to wait to see what the full details against my client are" before making further comment.
"We don't know why we've been charged. We've just got to wait and see what the details are. We are stunned," he said.
Mr Massey and Mr Burke have each been released on bail with a $10,000 personal undertaking ahead of their next court appearance in late November.
