Led by expat Kiwi lawyer David Hislop, QC, the appeal was based on doubts about material said to be brain tissue found on Lundy’s shirt that linked him to the crime scene.
Hislop produced expert evidence saying the specks of human tissue were in too poor a condition to be properly analysed.
Crown expert Rodney Miller, from Texas, used a technique called immunohistochemistry, or IHC, which he had previously tested on a chicken, to identify the tissue.
One significant revelation at the appeal was a report obtained by police before the 2002 trial, from Dr Heng Teoh, in which he said the material had degenerated so much that Lundy should not be convicted on the strength of tissue evidence alone. The report was never given to Lundy’s trial lawyers and was only handed to Hislop shortly before the Privy Council hearing.
