A man is set to stand trial for the stabbing murder of a tradie outside a Melbourne train station.
Jack Ledlin, 20, pleaded not guilty in Melbourne Magistrates Court on Tuesday to murdering 26-year-old Cam Smith at Seaford in November.
Scarlett Taylor, 21, and Liam Casley, 18, each pleaded guilty to affray by threatening to use unlawful violence, committing an indictable offence on bail and breaching bail.
They each had one charge of unlawful assault dropped, while Ledlin was committed to stand trial for murder.
The court was previously told Mr Smith was stabbed when he was confronted by a group of four people after stepping in to defend his girlfriend.
A 17-year-old from Frankston was also charged with affray, intentionally causing injury and committing offences while on bail over the incident.
Ledlin, Taylor and Casley are due to appear in Victoria's Supreme Court for a directions hearing on June 11.
