אֶחָד מִבַּעֲלֵי דִּינִין שֶׁאָמַר אִישׁ פְּלוֹנִי יָדוּן לִי וְאָמַר בַּעַל דִּינוֹ פְּלוֹנִי יָדוּן לִי הֲרֵי אֵלּוּ שְׁנֵי הַדַּיָּנִים שֶׁבֵּרֵר זֶה אֶחָד וְזֶה אֶחָד הֵם בּוֹרְרִים לָהֶן דַּיָּן שְׁלִישִׁי וּשְׁלָשְׁתָּן דָּנִין לִשְׁנֵיהֶן שֶׁמִּתּוֹךְ כָּךְ יֵצֵא הַדִּין לַאֲמִתּוֹ. אֲפִלּוּ הָיָה הָאֶחָד שֶׁבָּרְרוּ בַּעֲלֵי הַדִּין חָכָם גָּדוֹל וְסָמוּךְ אֵינוֹ יָכוֹל לָכוֹף אֶת בַּעַל דִּינוֹ שֶׁיָּדוּן אֵצֶל זֶה אֶלָּא גַּם הוּא בּוֹרֵר מִי שֶׁיִּרְצֶה:
The following law applies when one of the litigants says: "Let so and so act as a judge for me," and the other litigant says: "Let so and so act as a judge for me." Together the two judges which were chosen by each of the litigants respectively choose a third judge and the three of them adjudicate the case for the two litigants. In this manner, a true judgment will emerge. Even if the judge chosen by one of the litigants is a great sage who has received semichah, the one litigant cannot compel the other litigant to have him adjudicate the case. Instead, he also chooses a judge he desires.
