In a flawed but significant decision, the Ninth Circuit held that California Penal Code § 243(d), battery with injury, is a crime of violence. United States v. Perez (9th Cir. July 11, 2019). Because of Perez, criminal defenders must assume that § 243(d) is a crime of violence and seek other dispositions when necessary. Immigration advocates should appeal adverse decisions and preserve the argument on appeal. See this Advisory for a discussion of the decision, alternative pleas, and suggestions for arguments.
