Convicted gangland murderer Carl Williams has been refused an application for leave from jail to attend the funeral of his mother Barbara, who died last week.
His father, however, who is also in jail, will be allowed to attend.
Corrections Victoria released a statement on Wednesday saying it had refused Williams' bid, but had approved the application of his father George who is serving time on drugs charges.
Carl Williams is in Barwon Prison, serving 35 years for the murders of four gangland rivals and conspiring to murder a fifth during Melbourne's underworld war.
"The issues of security and public safety were key factors in considering this application," the Corrections Victoria statement read.
"Leave has been granted to George Williams, who will be escorted to the funeral of Barbara Williams by Corrections Victoria prison staff.
"Stringent security conditions are being put in place to accommodate his attendance."
Barbara Williams was found dead in the bedroom of her home in Essendon, in Melbourne's north-west, on Saturday morning after an apparent deliberate drug overdose.
