משנה: דִּינֵי מָמוֹנוֹת הַכֹּל מְלַמְּדִין זְכוּת וְחוֹבָה. דִּינֵי נְפָשׁוֹת הַכֹּל מְלַמְּדִין זְכוּת וְאֵין הַכֹּל מְלַמְּדִין חוֹבָה. דִּינֵי מָמוֹנוֹת הַמְלַמֵּד זְכוּת מְלַמֵּד חוֹבָה וְהַמְלַמֵּד חוֹבָה מְלַמֵּד זְכוּת וְדִינֵי נְפָשׁוֹת הַמְלַמֵּד חוֹבָה מְלַמֵּד זְכוּת. אֲבָל הַמְלַמֵּד זְכוּת אֵינוֹ יָכוֹל לַחֲזוֹר וּלְלַמֵּד חוֹבָה. MISHNAH: In civil suits, anybody33Every judge. may argue for credit or debit. In criminal suits, anybody may argue for acquittal but not everybody may argue for conviction34As explained in Sanhedrin 4:4:1" href="/Jerusalem_Talmud_Sanhedrin.4.4.1">Mishnah 5..

הלכה: דִּינֵי מָמוֹנוֹת הַמְלַמֵּד זְכוּת כול׳. רִבִּי אָמַר. וּבִלְבַד שֶׁלֹּא יְהוּ מְחוּסָּרִין לוֹמַר. אִישׁ פְּלוֹנִי אַתָּה זַכַּאי וְאַתָּה חַייָב. אֲבָל אִם הָיוּ מְחוּסָּרִין בָּמַשָּׂא וּמַתָּן לֹא בְדָא. רִבִּי יוֹסֵי בֶן חֲנִינִה אָמַר. אֲפִילוּ מְחוּסָּרִין בָּמַשָּׂא וּמַתָּן. HALAKHAH: “In civil suits, one who argued for credit,” etc. Rebbi said, if they only miss saying, Mr. X, you are acquitted, or you are convicted; it does not apply to the discussion37A judge who argued for acquittal during the discussion is barred from voting for conviction during the final vote but a judge originally arguing for acquittal may change his mind during the discussion and later argue for conviction. In the Sanhedrin.34b">Babli, 34b, Rav reads the Mishnah as implying that during the discussion, a person arguing for acquittal cannot then argue for conviction but the next day he may vote for conviction.. Rebbi Yose ben Ḥanina said, it also applies to the discussion38A judge originally arguing for acquittal cannot later argue for conviction..
