As for Kyaku, too, as opposed to China, where after the fall of the Tung dynasty, it had diminished into restrictive law which stated the qualifications for government officials, the share of Kyaku became high since not one new Ritsuryo code were made at all from the Yoro Ritsuryo code in Japan, and even laws and ordinances (for example, "konden einen shizai ho", the Law Permitting Permanent Ownership of Newly Cultivated Land) which denied the rules by the Ritsuryo codes were passed in the form of Kyaku.
また、格に関しても中国では唐の滅亡後は官人資格などを定めた限定的な法律に縮小されていくのに対して、日本では養老律令以後新規の律令が全く作られなくなったために格の占める比率が高くなり、律令による規定そのものを否定する法令（例墾田永年私財法）さえも格の形式によって出されるようになった。
