If her father heard and nullified the vow for her, and the husband did not manage to hear of the vow before he died, the father may go back and nullify the husband’s portion, and that will complete the nullification of her vow. Rabbi Natan said: This last ruling is the statement of Beit Shammai, but Beit Hillel say that he cannot nullify only the husband’s share of the vow but must also nullify his own share again.

Having completed its citation of the baraita, the Gemara now states its proof: Conclude from this that, according to the opinion of Beit Shammai, whoever nullifies the vow first completely severs his half of the vow, and therefore the father needed only to nullify the part left by the husband. However, according to the opinion of Beit Hillel, his nullification weakens the general force of the vow, so the father’s subsequent nullification must address the whole vow. The Gemara rules: Conclude from this baraita that the husband’s nullification weakens the general force of the vow, as the halakha is in accordance with Beit Hillel.

§ Rava raises a dilemma: Is there the possibility of a request to a halakhic authority about dissolving the ratification of one’s wife’s vow, or is there no possibility of a request to a halakhic authority about dissolving his ratification of one’s wife’s vow? One might seek to dissolve one’s ratification if he now desires to nullify the vow. Furthermore, if you say that there is the possibility of a request to dissolve his ratification, is there the possibility of a request to a halakhic authority about dissolving nullification of his wife’s vow, to allow him to ratify the vow in place of nullifying it? Or is there no possibility of a request to dissolve the nullification of his wife’s vow?

The Gemara answers: Come and hear that which Rabbi Yoḥanan says: A halakhic authority may be requested to dissolve ratification of one’s wife’s vow but may not be requested to dissolve nullification.

Rabba asks: If, after hearing one’s wife or one’s daughter’s vow, one said: It is ratified for you, it is ratified for you, and then a halakhic authority was requested about the first ratification and dissolved it, but one did not request dissolution of the second ratification, what is the halakha? Is the second ratification in force, or is it irrelevant, as it was performed on an vow that was already ratified and consequently never took effect?

The Gemara answers: Come and hear that which Rava said with regard to one who said: I take an oath that I will not eat, I take an oath that I will not eat: If a halakhic authority was requested to dissolve the first oath and dissolved it, the second oath goes into effect for him. Similarly, the second ratification goes into effect. Rabba further asks: If he said to her: The vow is ratified for you and nullified for you, and the ratification will not take effect unless the nullification takes effect, what is the halakha?
