Criminal lawyer Alex Lewenberg may have defended his last client after he was found guilty of professional misconduct for pressuring a sexual abuse victim who had helped police.

The decision was handed down by the Victorian Civil and Administrative Tribunal after the veteran solicitor admitted asking a victim of notorious paedophile David Cyprys to stay silent because both victim and perpetrator were Jewish.

The Victorian Legal Services Commissioner made the accusations against Mr Lewenberg over two separate incidents where he said that the victim, known as AVB, shouldn't help police.

In a verdict handed down by VCAT acting president Judge Pamela Jenkins on Thursday, Mr Lewenberg was found guilty of two charges of professional misconduct.
