Emperor Godaigo treated Emperor Kogon as 'the retired Emperor who abdicated from the position of Crown Prince, however, not officially succeeding to the throne, he was treated as an retired emperor exception,' which means the Emperor was indirectly denied and he was no longer Emperor. (Hence, theoretically this is a similar to the example of Koichijo-in who abdicated from being the Crown Prince and received the respected title of retired emperor.)
後醍醐側の光厳天皇への処遇は「朕の皇太子の地位を退き、天皇として即位はしていないが特例として上皇待遇とする」とされ即位の事実を否定されてしまった（したがって論理的には小一条院同様皇太子をやめて上皇の尊号を受けたという例になる）。
