No.

Spoiler:

At that point, Athena was already dying due to a divine artifact continuously sucking away her life. She only came to fight Godou at that point in time because she didn't have much time left alive.

They fought, Athena won (although she left Godou alive). Then her time ran out and she expired.

Thus, Godou didn't really defeat her, so no new authorities.
