The Ninth Circuit has determined that a Montana conviction for partner or family member assault is not a misdemeanor crime of domestic violence under federal criminal law. In so doing, the court recognized that the statute criminalizes infliction of emotional abuse, and thus, does not require the use or attempted use of physical force. “Taken together, these authorities show that a person can violate section 45-5-206(1)(a) through any form of communication that inflicts bodily injury in the form of emotional anguish. The infliction of emotional anguish does not require the use of physical force as that term is defined by federal law.”
Although this analysis arose in the criminal context, the immigration law definition of a crime of violence and a crime of domestic violence both require the use or attempted use of physical force. Indeed, the federal courts have acknowledged that the level of force required to meet the definition of a misdemeanor crime of domestic violence is lower than the degree of force required for a crime of violence or a crime of domestic violence. Thus, this analysis should be sufficient to demonstrate that a Montana conviction for partner or family member assault does not trigger the applicable immigration consequences for those offenses.
