The fact that Emperor Uda did not involve anybody but SUGAWARA no Michizane in deciding the next emperor, in one sense, intensified wariness and backlash against Michizane within the society of emperor and the nobles, and it was allegedly one of the causes of the incident in the later years (the Shotai Incident) in which SUGAWARA no Michizane was demoted and transferred to Dazai gon no sochi (provincial governor-general of the Dazai-fu [local government office in Kyushu region]).
宇多天皇が次期天皇の決定について菅原道真以外には関与させなかったという事実は、一面において天皇や貴族社会における道真への警戒心と反発を高め、後年菅原道真が大宰権帥に左遷された事件（昌泰の変）の原因になったとも言われている。
