A senior Adelaide lawyer has apologised to South Australia's Supreme Court for bringing a "wrecking ball" to the trial of four men accused of murder, after abandoning his client over a conflict of interest.
Thomas Nicholls, 31, Thomas Pinnington, 25, Jeremy Sandell, also 25, and Kain Mazomenos, 26, are accused of murdering 24-year-old Victor Codea at Adelaide High School in August 2020.
