The appellant, Thanh Tung Phan, appealed his conviction for first-degree murder.
The appeal raised two main grounds: an alleged error in the disposition of a Garofoli application concerning the judicial authorization for surveillance and tracking, and an error in admitting evidence of a history of violence between rival gangs (Chin Pac and Asian Assassinz) to establish motive.
The Court of Appeal found no error in the Garofoli ruling, concluding that the authorizing justice had reasonable and probable grounds even after excising inaccurate information from the Information to Obtain (ITO).
The court also found no error in admitting the gang evidence, determining its probative value for narrative, animus, and motive outweighed its prejudicial effect, especially given the trial judge's careful instructions and the manner of admission.
