The accused, Shou Chen, facing a second-degree murder charge, brought a mistrial application after his forensic psychiatrist, Dr. Mark Pearce, revised his opinion, no longer supporting a "not criminally responsible" (NCRMD) defence on a balance of probabilities.
The defence sought a mistrial to find another expert psychiatrist and secure Legal Aid funding.
The court dismissed the application, holding that a mistrial is a remedy of last resort and was not warranted.
The judge found that the change in expert opinion, partly attributable to defence counsel's delay in providing relevant reports, did not cause actual prejudice or unfairness, as the defence retained strategic options for presenting its case.
The court also noted the case's long history of defence-related delays.
