Charles J. Callan, Moral Theology
“ Direct annulment is the operation of a person distinct from the vower which, by affecting immediately the vower’s act, recalls the vow and makes it of no force. Hence, this kind of annulment may be exercised by all those who have such private authority over the will of the vower as to be able either to confirm or to cancel his acts. Private authority over the will of another is contained in the paternal power of the father over his children, in the domestic power of the husband over his wife, and in the governing power of a religious superior over his subjects. ”
