מִצְוַת עֲשֵׂה לִשְׁפֹּט הַשּׁוֹפֵט בְּצֶדֶק שֶׁנֶּאֱמַר (ויקרא יט טו) "בְּצֶדֶק תִּשְׁפֹּט עֲמִיתֶךָ". אֵי זֶהוּ צֶדֶק הַמִּשְׁפָּט זוֹ הַשְׁוָיַת שְׁנֵי בַּעֲלֵי דִּינִין בְּכָל דָּבָר. לֹא יְהֵא אֶחָד מְדַבֵּר כָּל צָרְכּוֹ וְאֶחָד אוֹמֵר לוֹ קַצֵּר דְּבָרֶיךָ. וְלֹא יַסְבִּיר פָּנִים לְאֶחָד וִידַבֵּר לוֹ רַכּוֹת וְיָרֵעַ פָּנָיו לְאַחֵר וִידַבֵּר לוֹ קָשׁוֹת:
It is a positive commandment for a judge to adjudicate righteously, as Leviticus 19:15 states: "Judge your colleagues with righteousness." What is meant by a righteous judgment? Equating the litigants with regard to all matters. One should not be allowed to speak to the full extent he feels necessary while the other is told to speak concisely. One should not treat one favorably and speak gently to him and treat the other harshly and speak sternly to him.
