In the tenth century, when the authority related to trials of government officials' crimes was moved to Jin no sadame (ancient cabinet council) of Daijokan, kanmon concerning charges and penalties of crime accounted for the large majority of Myobo kanmon, so they were especially called 'Zaimyo kanmon' (kanmon for charges).
なお、10世紀に入ると、官人の犯罪に関する裁判の権能が太政官の陣定に移された関係上、犯罪の罪名や処罰に関する明法勘文が大きな部分を占めて、特に「罪名勘文」（ざいみょうかんもん）とも呼ばれている。
