While the oldest shinsei is considered to have been issued in 947, Chohogannenrei is the first law which contains all of the three fundamental elements of shinsei in the Middle Ages: "(Shinto) shrines and (Buddhist) temples," "kasateishi (prohibition of the luxury beyond one's means or position)" and "strict enforcement of government affairs."
新制そのものの最古は天暦元年（947年）とされているが、中世における新制の基本的要素である「神社仏寺」「過差停止」「公事催勤」の3つの項目が揃った法令としては最初のものであった。
