Reference for Bekhorot 85:1
לפסול במקום אחים ולחלוץ שלא במקום אחים איכא בינייהו:
The difference is with reference to disqualifying [the woman] where there are suitable brothers.<span class="x" onmousemove="('comment',' If there are other suitable brothers and the tumtum hastens to release his sister-in-law by halizah. Now according to R. Judah his action is of no consequence and it does not prevent one of the others from carrying out the halizah ceremony, or marrying her; whereas according to R. Jose, since we only have a doubt lest the tumtum should be a saris, the action of the tumtum disqualifies her for the brothers, as it may be that the halizah is valid and, therefore, none of the brothers may marry her. They have, in consequence, to give her halizah again.');"><sup>1</sup></span>
