Court of Appeals of the District of Columbia, Hunter v. District of Columbia (1918)
“ Unlawful assembly is a statutory offense in this District, but the strict rule of conforming to the language of the statute as to offenses purely statutory has its exceptions. "Where the offense is purely statutory, having no relation to the common law, it is, 'as a general rule, sufficient in the indictment to charge the defendant with acts coming fully within the statutory description, in the substantial words of the statute, without any further expansion of the matter.' 1 Bishop, Crim. ”
