Tony Mokbel's recovery from a brain injury sustained during a prison attack has been hampered due to his isolation from other inmates.
The Melbourne drug kingpin is continuing to suffer the effects of a traumatic brain injury after he was set upon by two 21-year-old prisoners at Barwon near Geelong four years ago.
Mokbel, 57, appeared in Victoria's Court of Appeal on Monday, where his lawyers applied for him to be re-sentenced after one of his previous convictions was quashed due to the Lawyer X scandal.
