Prosecutors have dropped a charge of grievous bodily harm that was associated with the same incident.
The individual involved chose not to respond to journalists’ inquiries and is slated to return to the same courtroom on May 27.
Priya Brown, Picton’s widow, attended the court hearing but refrained from making any comments to the media present outside.
Previously, a Perth court was informed that Picton was removed from the Paramount Nightclub due to being intoxicated.
Shortly after, Dewar and Picton encountered each other again in close proximity to the club.
It is alleged that Dewar punched Picton in the face, causing him to fall and hit his head on the pavement.
He died in hospital several weeks later.
Prosecutors on Wednesday also discontinued Dewar’s charge of causing bodily harm related to an incident in the Perth suburb of Kalamunda on December 25.
Dewar last week pleaded guilty in Armadale Magistrates Court to assault occasioning bodily harm over the incident.
A Perth court previously heard Dewar punched a man in his 40s to the ground shortly after midnight after an incident involving the younger man’s sister.
Dewar then recorded the man lying on the ground with his mobile phone and said “don’t hit on my sister” and “bro, keep snoring”, the court was told.
The man suffered minor injuries and later told police he didn’t remember the incident, which was recorded on CCTV.
Dewar is scheduled to reappear in Armadale court for sentencing on May 6 over the Kalamunda incident.
