June 26, 2006) (California conviction of simple battery, in violation of Penal Code 242, did not qualify as deportable domestic violence conviction, under INA 237(a)(2)(E)(i, 8 U.S.C. 1227(a)(2)(E)(i), where record of conviction did not establish necessary domestic relationship), opinion amended on denial of rehearing, ___ F.3d ___, 2006 WL 2819961 (9th Cir. Oct. 4, 2006) (amendment deleted the following sentence: "Where, as here, there are statutes directly addressing domestic violence, such as California Penal Code sections 243(e)(1) and 273.5, only the most convincing proof of the nature of a conviction for a more general crime will suffice to establish a crime of domestic violence." 451 F.3d at 1059-60 [emphasis in original]).
