Story summary

Dr. Stewart Proper, an orthopaedic surgeon based in Glen Iris, had his medical registration cancelled by the Victorian Civil and Administrative Tribunal (VCAT) after threatening to "piss in the mouth" of a colleague during surgery and engaging in online harassment. The incident occurred when a drape fell near the patient's wound during an operation, leading Dr. Proper to make the vulgar threat. Although he later apologized for his outburst, he went on to post multiple offensive social media messages directed at three psychiatrists who were involved in his own involuntary mental health treatment. VCAT ruled that Dr. Proper’s behavior constituted professional misconduct and showed a "persistent lack of insight" and an unwillingness to take responsibility for his actions. His only suggestion for managing his behavior was chewing gum, highlighting the severity of his conduct issues. The tribunal initially suspended him but ultimately canceled his registration due to continued inappropriate behavior.
