A Melbourne man charged with manslaughter after the heart surgeon he allegedly "coward punched" later died, was on bail when the attack happened, court documents reveal.
Joseph Esmaili, 22, appeared via videolink in Melbourne Magistrates Court on Friday, accused of punching Patrick Pritzwald-Stegmann near the entrance of Box Hill Hospital on May 30.
Initially charged with multiple counts of intentionally and recklessly causing serious injury, Esmaili was additionally charged with manslaughter while on bail and unlawful killing following Dr Pritzwald-Stegmann's death on June 28.
Doctors who treated the surgeon will be cross examined about the extent of Dr Pritzwald-Stegmann's injuries and how he appeared after the incident, say defence lawyers, who also plan to question other witnesses.
Treating doctors noted the surgeon was "agitated" and appeared "disorientated" after the alleged attack, defence barrister John Desmond told the court.
Another witness claimed he was "thrashing about" on the ground after the incident, the lawyer added.
The extent and nature of Dr Pritzwald-Stegmann's injuries, including "extensive bruising" around his left eye, a nose bleed and his attempts to stand will also be examined.
Up to six witnesses are expected to give evidence about the incident.
Esmaili is due to face court next in February for a five-day committal hearing.
