47 Finally, the accused seeks to exclude the following evidence, which is apparently to be relied upon by the Crown to demonstrate evidence of consciousness of guilt, or implied admissions of guilt: a hairdresser, Domenica D'Alberto, who will give evidence about discussions she had with the accused, before and after the date of Ms Halvagis' murder, about him changing his hairstyle; an optometrist, Isabella La Rocca, and a spectacle maker, Jack Sgourakis, who will give evidence about the accused changing his style of glasses in early November 1997; and evidence from Ms La Rocca as to the accused having a scratch on his cheek on 7 November 1997, which he told her he got at work, together with evidence from his then-employer, John Kazakis, that the accused did not report any workplace injury in November 1997. The accused seeks to have the evidence of all four witnesses excluded under s 137 of the Evidence Act 2008, on the basis that the probative value of the evidence is outweighed by the danger of unfair prejudice to him.
