Son loses appeal over parents' murders

A Sydney man charged with the stabbing murders of his parents 14 years ago has lost a bid to avoid standing trial.

Jeffrey Gilham is accused of killing his parents at Woronora, in Sydney's south, in August 1993.

Gilham applied for the charges to be stayed using the double jeopardy principle but lost.

In appealing against that decision, he argued there was an abuse of process.

Gilham had pleaded guilty to the manslaughter of his brother, who he blamed for killing their parents.

In his appeal, he argued he could not be prosecuted for his parents' murders because his earlier plea was accepted on the basis his brother was the killer.

But the NSW Court of Criminal Appeal has today dismissed Gilham's appeal on the grounds there was insufficient evidence at the time.

He will face trial in February.
