In April 705, after the fixed number of Dainagon (Major Counselor) was reduced by two people, the post of Chunagon (Middle Counselor), which had been abolished at that time of the establishment of Taiho Code, was revived as giseikan (Legislature) (the start of 'Ryoge no kan' (newly-established governmental posts which were not included in Ritsuryo Code)), TAKAMUKO no Maro, AWATA no Mahito and ABE no Sukunamaro were newly appointed.
慶雲2年（705年）4月、大納言の定員を2人削減するとともに、大宝令制定に伴い廃止されていた中納言が朝廷の議政官として復活し（「令外の官」の始まり）、高向麻呂・粟田真人・阿倍宿奈麻呂を任命した。
