Morgon had an altercation with Greg Davies, the head of the Police Association in Victoria, while riding his bike in January 2011.

According to The Age, Morgon confronted Davies after Davies’ car pulled out in front of Morgon, with the union head also giving Morgon a “two fingered salute”.

During the confrontation, Morgon headbutted Davies with his bike helmet, drawing blood from his victim.

Morgon was found guilty of unlawful assault and assault with a bike helmet, but no conviction was recorded. Two other charges were dismissed.

A spokesperson from Allens told Lawyers Weekly that despite being found guilty of two counts of assault, Morgon was still employed by the firm as a senior associate.

“Mr Morgan pleaded not guilty and strongly denied the complainant's version of events in court,” said the firm in a statement. “He disclosed the incident to the firm as soon as he was charged. He has not sought publicity on what is essentially a personal matter and has made no public comment, nor do we intend to on his behalf.”

Morgon declined to be interviewed by Lawyers Weekly.

The high profile barrister Neil Clelland SC acted for Morgon. Allens would not reveal whether his defence was paid for by the firm or by Morgon.

Davies told The Age outside the Magistrates’ Court that Morgon turned around to confront him after he had pulled out in front of him, and then rode up to him after he had alighted from his car at his home.

“As I grabbed hold of the handlebars he quite deliberately leant forward and headbutted me,” said Davies.

Davies also said his wife and daughter witnessed the assault.
