Zamudio

dissenting.

Trial judges are accorded wide discretion in matters of relevancy. In my opinion, the district judge did not abuse her discretion in ruling that the proposed psychological testimony was not relevant. The case relied on by the majority, United States v. Vallejo, 237 F.3d 1008 (9th Cir. 2001) is clearly distinguishable.

United States v. Vallejo, 237 F.3d 1008, 1019-20 (9th Cir.2001). Given that the trial turned on whether Zamudio knowingly possessed the marijuana, the potential…
