To give a representative example, MINAMOTO no Yorisada, who had committed adultery with FUJIWARA no Suishi, a shoji (principal handmaid) of Crown Prince Okisada, was not allowed to enter the Imperial Court in spite of the fact that he was already a kugyo by the time Imperial Prince Okisada was enthroned (Emperor Sanjo) ("Okagami" [the Great Mirror]).
代表的な例として東宮居貞親王の尚侍・藤原綏子と密通した源頼定は居貞親王（三条天皇）即位後に既に公卿であるにも関わらず昇殿が許されなかった（『大鏡』）。
