According to the "Chousyu-ki" (an article of June 7, 1135) written during the Hoei period, when the retired Emperor Yozei had tried to enter the palace, Emperor Uda forbade the retired Emperor Yozei from entering the palace without his permission; however, later on Emperor Uda tried to enter the palace when the Shotai-no-Hen/Shotai Incident happened, and he tried to ask Emperor Daigo to stop SUGAWARA no Michizane's degradation, but could not do so because of the regulation that he himself had made.
保延年間に書かれた『長秋記』（保延元年6月7日条）によれば、陽成上皇が宇多天皇の内裏に勝手に押し入ろうとしたために、上皇といえども天皇の許しなく内裏に入る事が禁じられたが、後に昌泰の変が起きた時に醍醐天皇に菅原道真の左遷を止めさせようとして内裏に入ろうとした宇多上皇がこの決まりを盾に阻まれたと記されている。
