Three men — Sudo Cavkic, Costas Athanasi and Julian Michael Clarke — were tried and convicted for his murder after three trials before the Supreme Court of Victoria.
Frank De Stefano, a former gambling associate of Clarke, gave evidence at each of the three trials, as did Jack Collins, Australian football great and personal friend of Allan.
Clarke gambled with former Geelong Mayor Frank De Stefano, whom he allowed to launder considerable money through the trust account, without Allan's knowledge.
The plan almost succeeded but for two alert policemen, Senior Constables Michael Strongman and Travis McCarthy, who apprehended Cavkic driving Allan's car, a blue Mercedes Benz, in a dead end street at Altona Meadows, a western suburb of Melbourne.
[14] Justices Virginia Bell and Susan Crennan of the High Court of Australia refused an application seeking special leave to appeal on 11 December 2009.
