EFFECT: Modifies the conduct that constitutes a Hate Crime offense to include when a person commits a specified act in whole or in substantial part, rather than in whole or in part, because of the person's perception of another person's certain characteristics. Specifies that "in whole or in substantial part" means that the perpetrator's bias must be a cause in fact of the offense regardless of whether other causes also exist, and that the bias must be a substantial factor if multiple concurrent motives exist.
