Jerusalem Talmud Sanhedrin 6.2

משנה: אִם מָצְאוּ לוֹ זְכוּת פְּטָרוּהוּ וְאִם לָאו יוֹצֵא לִיסָּקֵל. וְהַכָּרוֹז יוֹצֵא לְפָנָיו אִישׁ פְּלוֹנִי בֶּן פְּלוֹנִי יוֹצֵא לִסָּקֵל עַל שֶׁעָבַר עֲבֵירָה פְלוֹנִית וּפְלוֹנִי וּפְלוֹנִי עֵדָיו וְכָל מִי שֶׁהוּא יוֹדֵעַ לוֹ זְכוּת יָבוֹא וִילַמֵּד:

MISHNAH: If they found him innocent, they free him, otherwise he is led to be stoned. The herald goes before him: “X ben Y is led to be stoned because he committed crime Z; U and V testified against him. Anybody who knows of his innocence shall come and argue.”

הלכה: אִם מָצְאוּ לוֹ זְכוּת כול׳. תַּנֵּי. שׁוֹר הַיּוֹצֵא לִיסָּקֵל וְנִמְצְאוּ עֵידָיו זוֹמְמִין. רִבִּי יוֹחָנָן אָמַר. כָּל הַקּוֹדֵם בּוֹ זָכָה. רֵישׁ לָקִישׁ אָמַר. הֶפְקֵר טָעוּת הוּא. וְכֵן עֶבֶד הַיּוֹצֵא לִיסָּקֵל וְהִקְדִּישׁוֹ בְעָלָיו. רִבִּי יוֹחָנָן אָמַר. זָכָה לְעַצְמוֹ. רֵישׁ לָקִישׁ אָמַר. יֵיאוּשׁ שֶׁלְּטָעוּת הָיָה.

HALAKHAH: “If they found him innocent,” etc. It was stated: If a bull was led out to be stoned when its witnesses were found to be perjured, Rebbi Joḥanan said, the first to come acquires it; Rebbi Simeon ben Laqish said, it was a false declaration of ownerlessness. Similarly, if a slave was led out to be stoned when his owner dedicated him to the Temple, Rebbi Joḥanan said, he acquired himself; Rebbi Simeon ben Laqish said, it was false despair.
