Mishnah in Maseches Gitin: A betrothed na'arah - she or her father may accept her get. (R. Yehudah disagrees and holds that only her father may accept it.)

Raish Lakish: The same dispute that exists for Gitin exists for Kidushin.

R. Yochanan: All agree that her father must accept her Kidushin.

Raish Lakish certainly agrees that she cannot independently perform nisuin (chupah) since she cannot cause him to lose her earnings without his consent.

According to R. Yochanan, she is powerless without the consent of her father, so she cannot appoint a shaliach.

According to Raish Lakish, since she can accept kidushin without her father, she can also appoint a shaliach.

Question against R. Yochanan (our Mishnah): A man can betroth, himself or through a shaliach. A woman can accept betrothal, herself or through a shaliach. (Since a na'arah is a woman, the Mishnah allows her to independently accept her own kidushin.)

Answer: The Mishnah refers to an adult woman.

Question (Mishnah): A girl (under 12) who told a shaliach, "Accept for me my get'', is only divorced when it reaches her hand. (However, if she had been a na'arah, she could appoint a shaliach.)

Answer: If she is an orphaned na'arah, she has 'a hand' and she can appoint a shaliach.

Question (in the same Mishnah): If a father said to a shaliach, "Go and accept my daughter's get'', he may not retract. (This shows that the Mishnah cannot be discussing an orphan girl.)

Answer: The two parts of the Mishnah are discussing different cases...the first part is discussing an orphan and in the second part, she has a father.

Question against Raish Lakish (our Mishnah): A man can marry off his daughter when she is a na'arah himself or through a shaliach. (However, when she has a father, she cannot do this.)

Answer: This statement was said by R. Yehudah who holds that two hands are not able acquire the same thing.

R. Asi: A Rabbinical student came out of the Study Hall and said that the ruling there was like R. Yochanan and they relied upon it.

It was not that this student was suitable to rely on but rather, since he said it in close proximity to the Study Hall, it could have easily been verified.

Rav Hamnuna citing R. Asi: A girl who accepted Kidushin and then later physically matured, her father can refuse the marriage but not her (because the Mishnah teaches that a girl may only refuse a marriage until she physically matures).

This ruling does not follow R. Yochanan or R. Shimon ben Lakish. According to R. Yochanan, only her father could accept Kidushin, so there was no marriage at all. According to R. Shimon ben Lakish, it is a Torah marriage and refusal would not help at all.

Rather, it must follow R. Yochanan and even though R. Yochanan says that all agree that only her father accepts Kidushin but not her, he agrees that that father must refuse for her in this case.

R. Ba bar Kahana/ R. Yaakov bar Idi citing R. Yehoshua ben Levi: There was a case where a girl was married off by her father but she performed nisuin without her father's consent and her father came and removed her from the chupah.

R. Yaakov bar Acha citing R. Yehoshua would often say that R. Yehoshua ben Levi disagreed with R. Shimon ben Lakish (who said that a girl may marry herself off without her father's consent).

Rejection: Even R. Shimon ben Lakish agrees that a girl cannot perform Nisuin without her father's consent as it will cause him the loss of her earnings.
