He applied to the Court of Appeal to gain access to microscope slides and blocks taken from Carter’s brain during the post-mortem examination. The slides are in custody of forensic pathologist Dr Martin Sage. Gray wants the slides examined by a consultant neuropathologist in the UK to enable him to comment on the merits of his appeal. Sage was reluctant to release the slides without a court order compelling him to do so. According to a recently released Court of Appeal decision, Sage expressed concerns about releasing the slides when the post-mortem was not part of the evidence at trial, and before the coronial inquest had been completed.
