To strengthen the power of shogun against the shogunal deputy and others, the sixth shogun Yoshinori ASHIKAGA started out to extend the influence of gozen-sata that was chaired and attended by the shogun -- he included shomu (land management) as well as zasso on the agenda of gozen-sata, and also organized gozen-sata shu (members of gozen-sata) from working-level officials of yuhitsu (amanuenses) and bugyonin (magistrates) and qualified them to attend gozen-sata.
6代将軍足利義教は、管領などに対抗して将軍の権威を高めるために、将軍が主宰・臨席する御前沙汰の権威強化に乗り出し、雑訴のみならず所務も御前沙汰の評定対象として加え、実務を担当する右筆・奉行人の中から御前沙汰衆を選んで御前沙汰への参加資格を与えた。
