On the other hand, it is difficult to find the evidence that Dokyo was deeply involved in this incident because of the following reasons; Empress Shotoku did not proceed with the move to let Dokyo ascend the throne based on the first oracle although she could have done so after she and Dokyo denied the second oracle and exiled Kiyomaro; furthermore, there was no active movement in the opposition factions such as Fujiwara clan concerning the removal of Empress Shotoku or Dokyo using this incident as a legitimate reason.
その一方で、称徳天皇や道鏡が清麻呂を流した事で2番目の神託を否認した以上、最初の神託に基づいて道鏡への皇位継承を進めることも可能であった筈なのに事件以後に全くそうした動きを見せていない事や逆に藤原氏らの反対派がこの事件を直接の大義名分として天皇や道鏡排除に積極的に動いていない事から、道鏡がこの事件に深く関わっていたとする証拠を見出す事は困難である。
