Introduction

In the landmark case State of Washington v. Louis A. DeVincentis, the Supreme Court of Washington addressed a pivotal issue concerning the admissibility of prior bad acts under Evidence Rule (ER) 404(b). This case examined whether evidence demonstrating a defendant's prior misconduct must exhibit unique or atypical methods of committing a crime or if substantial similarity suggesting a common scheme or plan suffices. The parties involved included Louis A. DeVincentis, the petitioner, and the State of Washington, represented by Norm Maleng and colleagues. DéVincentis had been convicted of second-degree rape of a child and second-degree child molestation, with the State seeking to admit evidence of his prior sexual misconduct with young girls to establish a pattern or plan.

Summary of the Judgment

The Supreme Court of Washington, in an en banc decision, affirmed DeVincentis' conviction and upheld the Court of Appeals' interpretation that admission of prior bad acts under ER 404(b) does not necessitate uniqueness or atypical methods. Instead, substantial similarities demonstrating a common scheme or plan are sufficient. The court emphasized that when admitting such evidence, the trial court must only ascertain that the prior bad acts exhibit marked similarities to the current charges, thereby indicating a general plan rather than relying on unique characteristics of the misconduct.

Analysis

Precedents Cited

The judgment extensively references prior cases to elucidate the framework for admitting prior bad acts:

• STATE v. LOUGH (1995): Established the criteria for admitting prior bad acts to prove a common scheme or plan, emphasizing substantial similarity over uniqueness.
• STATE v. DEWEY (1998): Represented Division Two of the Court of Appeals' stance, which incorrectly conflated common scheme or plan with modus operandi by requiring uniqueness.
• STATE v. GRISWOLD (2000): Reinforced the interpretation that substantial similarity suffices, aligning with Dewey's approach.
• PEOPLE v. EWOLDT (1994, California): Provided guidance on the necessity of markedly similar acts to establish a common scheme or plan.
• STATE v. WERMERSKIRCHEN (1993, Minnesota): Highlighted the importance of similarity in time, place, and modus operandi over uniqueness.
• Wigmore's Treatise on Evidence: Cited to support the argument that substantial similarity, rather than uniqueness, is required for admissibility.

Legal Reasoning

The court's legal reasoning centered on differentiating between the "common scheme or plan" exception and the "modus operandi" exception under ER 404(b). While modus operandi pertains to proving the identity of a perpetrator through unique methods, a common scheme or plan aims to establish that prior bad acts are part of a broader criminal strategy. The court criticized Division Two's requirement of uniqueness, clarifying that such a stipulation mistakenly merged the two exceptions. Instead, the court affirmed that substantial similarity indicating a shared plan is sufficient without necessitating atypical methods.

The court underscored that the trial court had meticulously applied the four-part analysis from Lough, ensuring that the admitted prior bad acts were relevant, sufficiently similar, and more probative than prejudicial. This careful balancing act protected against the misuse of propensity evidence while allowing the establishment of a defendant's pattern of behavior.

Impact

This judgment has profound implications for future cases in Washington:

• Clarification of ER 404(b) Application: Courts will now focus on the substantial similarity of prior acts to establish a common scheme or plan, removing the necessity for uniqueness.
• Consistency in Admissibility: By resolving the divisional split, the judgment promotes uniform application of evidentiary standards across different appellate divisions.
• Enhanced Admissibility of Patterns: Prosecutors can more readily admit prior bad acts that demonstrate a defendant's modus operandi without the burden of proving atypical methods.
• Safeguards Against Prejudice: The emphasis on balancing probative value with prejudicial effect ensures that evidence is admitted judiciously.

Complex Concepts Simplified

Evidence Rule (ER) 404(b)

ER 404(b) prohibits the admission of evidence regarding a defendant's past crimes solely to demonstrate a propensity to commit similar offenses. However, it allows such evidence for specific purposes like establishing motive, opportunity, intent, or, pertinent to this case, a common scheme or plan.

Common Scheme or Plan vs. Modus Operandi

- Common Scheme or Plan: Used to show that prior bad acts are part of an overarching strategy or pattern, indicating that the defendant systematically engages in certain behaviors.

- Modus Operandi: Focuses on the unique methods or techniques a defendant uses to commit a crime, primarily to establish identity.

Substantial Similarity

For evidence under ER 404(b) to be admissible as a common scheme or plan, there must be significant similarities between the prior and current acts. This does not mean the methods must be unique, but they should be sufficiently alike to suggest a shared strategy.
