5מִי שֶׁהֵבִיא עֵדִים וְנֶחְקְרָה עֵדוּתָן וְהוּזַמּוּ וְחָזַר וְהֵבִיא עֵדִים אֲחֵרִים בְּאוֹתָהּ הַטַּעֲנָה עַצְמָהּ וְהוּזַמּוּ אֲפִלּוּ מֵאָה כַּת. וְאַחַר כָּךְ הֵבִיא עֵדִים אֲחֵרִים בְּאוֹתָהּ הַטַּעֲנָה עַצְמָהּ וְנִמְצֵאת עֵדוּת אֵלּוּ הָאַחֲרוֹנִים מְכֻוֶּנֶת. דָּנִין עַל פִּיהֶן. שֶׁאַף עַל פִּי שֶׁהֻחְזַק זֶה שֶׁטָּעַן טַעֲנָה זוֹ לְהָבִיא עֵדִים שַׁקְרָנִים הֲרֵי לֹא הֻחְזְקוּ אֵלּוּ הָעֵדִים הָאַחֲרוֹנִים שֶׁהֵן מְשַׁקְּרִין. אֲבָל שְׁטָר שֶׁקָּרָא עָלָיו עַרְעָר וְהוּא שֶׁיָּבוֹאוּ שְׁנַיִם וְיֹאמְרוּ מִמֶּנּוּ שָׁאַל לְזַיֵּף לוֹ שְׁטָר זֶה אַף עַל פִּי שֶׁנִּתְקַיֵּם הַשְּׁטָר מֵחוֹתְמָיו אֵין גּוֹבִין בּוֹ לְעוֹלָם. וְיֵרָאֶה לִי שֶׁאִם בָּאוּ עֵדֵי הַשְּׁטָר וְהֵעִידוּ הֵן בְּעַצְמָן עַל כְּתַב יָדָן גּוֹבִין בּוֹ: סְלִיקוּ לְהוּ הִלְכוֹת עֵדוּת בְּסַ"ד
The following rules apply when a person brings witnesses, their testimony is investigated, they were disqualified through hazamah, and then he brought other witnesses concerning the same claim and they were also disqualified through hazamah. Even if he brings 100 groups who are disqualified, if afterwards, he brings other witnesses regarding that same claim and the testimony of these witnesses is found to be accurate, the case is adjudicated on this basis. Even though the plaintiff can be presumed to bring lying witnesses, we do not operate under the presumption that these witnesses are lying. When, by contrast, there is a legal document concerning which a protest has been sustained, i.e., two witnesses came and said that the plaintiff told them to forge this legal document, we never use that legal document to expropriate property even if the authenticity of the signatures of the witnesses is validated. It appears to me that if the witnesses to the legal document came and testified concerning their signature, the legal document may be used to expropriate money.
