Talmud do Powtórzonego Prawa 1:17

⁸⁹Tosephta 1:7, Tanhuma Mišpatim 6, Sheiltot Mišpatim 58, and in all Medieval quotes; only in Babli 6b both in the Munich ms. and editio princeps incorrectly: R. Simeon ben Laqish.“Rebbi Jehudah ben Laqish said: If two people appeared before a judge, one decent and one agressive. Before he started to hear their arguments, he may tell them, I will not hear your case, lest the agressive one lose his case and become his enemy. After he started hearing their arguments, he may not tell them, I will not hear your case, for it is said,⁹⁰Deut. 1:17. do not be afraid of anybody.

⁹¹Tosephta 1:8.“Rebbi Joshua ben Qorha says, if somebody⁹²In a similar, anonymous, baraita in the Babli (Ševuot 31a): A student sitting before his teacher. This probably has to be understood here. was sitting next to a judge and saw a benefit for the poor and a detriment for the rich, from where that he should not keep silent? For it is said⁹⁰Deut. 1:17., do not be afraid of anybody.

Do not act as an advocate for one side. How so? This teaches that if you came to the house of study and heard a general teaching or a legal teaching, do not respond immediately. Rather, sit and ask about the reasoning [behind their teaching, and in what context they made such a judgment. To the one who gave the legal teaching, ask first about the legal principle and the timing of the case.] When two litigants come before you for judgment, one poor and one rich, do not say to yourself: How can I make sure to exonerate the poor one and charge the rich one? Or how (can I exonerate the rich one and charge the poor one? For if I charge the poor one, then he will become my enemy, but if I exonerate the poor one, then the rich one will become my enemy. And do not say to yourself: How) can I take this one’s money and give it to that one? For the Torah says (Deuteronomy 1:17), “Do not be partial in judgment.”
(Rabbi Meir would say: What do we learn from this:) “Hear out low and high alike” (Deuteronomy 1:17)? That one person should not be made to stand while the other one sits, or one person be allowed to talk as much as he wants while the other is told to be brief. (Rabbi Yehudah said: I heard that if the judges want to seat both litigants at once, they may do so; it is not forbidden. And what is forbidden? That one person sits and one stands. [Rather, what do we learn from) “low and high alike”?] That the judgment of the lowly be just the same for you as the judgment of the exalted, and [the judgment] of a perutah be just the same to you as the judgment of a hundred manah.
