Talmud for Eduyot 1:5
וְלָמָּה מַזְכִּירִין דִּבְרֵי הַיָּחִיד בֵּין הַמְרֻבִּין, הוֹאִיל וְאֵין הֲלָכָה אֶלָּא כְדִבְרֵי הַמְרֻבִּין. שֶׁאִם יִרְאֶה בֵית דִּין אֶת דִּבְרֵי הַיָּחִיד וְיִסְמֹךְ עָלָיו, שֶׁאֵין בֵּית דִּין יָכוֹל לְבַטֵּל דִּבְרֵי בֵית דִּין חֲבֵרוֹ עַד שֶׁיִּהְיֶה גָדוֹל מִמֶּנּוּ בְחָכְמָה וּבְמִנְיָן. הָיָה גָדוֹל מִמֶּנּוּ בְחָכְמָה אֲבָל לֹא בְמִנְיָן, בְּמִנְיָן אֲבָל לֹא בְחָכְמָה, אֵינוֹ יָכוֹל לְבַטֵּל דְּבָרָיו, עַד שֶׁיִּהְיֶה גָדוֹל מִמֶּנּוּ בְחָכְמָה וּבְמִנְיָן:
And why do we mention the words of the one, among the many, if the halachah is only in accordance with the many? So that if beth-din holds with the view of the one, and relies upon it [against the view of the many], a [future] beth-din cannot annul the words of its fellow beth-din unless it be greater in wisdom than that of the first], and in number [i.e., that the number of disciples in the second be greater than the number of disciples in the first.] If it were greater in wisdom but not in number, or in number but not in wisdom, it cannot annul its words unless it be greater (than the first) both in wisdom and in number.

However, since the biblical commandment of the Sabbatical is intrinsically connected with that of the Jubilee, it cannot be in force when the Jubilee is not in force, i. e., if not all of Israel dwells on the ancestral land distributed by Joshua. Therefore during the Second Commonwealth the Sabbatical was a rabbinic institution. Rabban Gamliel (of Jabneh, the first Patriarch after the destruction of the Second Temple) decided that in the absence of the Temple the rabbinic institution of the Sabbatical should continue without extensions. While his Court was the highest authority in his time, he could not compete in standing with the Men of the Great Assembly who established the rules for the Second Commonwealth..

Did we not state328Mishnah Idiut 1:5., “for no court may invalidate the words of another court unless it be greater in wisdom and numbers”? There came Rav Abun, Rav Jehudah in the name of Samuel: they taught this only about other [decrees] than the eighteen. Therefore, the eighteen even a greater one cannot abolish, because they fought for it with their lives. Rebbi Mana said, this makes it reasonable that it is not so; since this is a case of force it is invalid344The first argument was that the 18 decrees must be inviolate because people were killed for it; R. Mana’s argument is that the decrees were imposed by force and therefore are intrinsically invalid.. They objected, is there not oil which is of the eighteen? And Rebbi (Jonathan) [Joḥanan]343The text in parentheses is that of the Leiden ms., the [correct] one in brackets is from the Geniza fragment which is legible at this place. objected! Rav Cahana the son of Rebbi Ḥiyya bar Abba; Rebbi Aḥa bent it in the name of Rebbi Joḥanan: Oil, they abolished what was abolished345As stated earlier, the decree about Gentile olive oil never was accepted by the people; it never became enforceable law..
