United States v. Parker, 987 F.3d 1234 (9th Cir. 2023)
United States v. Parker is a pivotal case concerning the admissibility of witness testimony regarding a defendant's prior conduct, specifically within the context of federal criminal proceedings.
Whether the admission of witness testimony regarding the defendant's prior conduct was permissible under Federal Rule of Evidence 404(b).
Federal Rule of Evidence 404(b) allows the admission of evidence of a person’s prior conduct for purposes other than to prove character, such as proving motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake, or lack of accident.
The Ninth Circuit affirmed the district court's decision, holding that the testimony regarding Parker's prior fraudulent conduct was admissible under Rule 404(b) as it was relevant to proving Parker's intent to commit the wire fraud charged.
The case of United States v. Parker is significant for its detailed analysis of the contours of Rule 404(b) in criminal proceedings. It serves as a foundational reference for law students and legal practitioners alike looking to understand the boundaries between permissible evidentiary use of prior conduct and inadmissible character evidence. The decision illustrates the application of a balancing test to weigh probative value against prejudicial harm, a critical skill for any litigator.
