Historical facts, however, back Dvornik's argument because +Photius' restoration was not revoked by Pope John VIII, but only after the Great Schism in the 11th century. If Pope John VIII did revoke the Council of 879, then Photius would have been denounced (again) and deposed, as in the previous Council a decade earlier.

The condemnations of 869 concerning his prior illegal election did not apply to the then current situation and there was no need to restate them. This does not imply that John VIII accepted as binding the theological statements of 879.
