Sanhedrin 88B

בן סורר ומורה, שרצו אביו ואמו למחול לו ⁠– מוחלין לו.

The second matter is that in the case of a stubborn and rebellious son whose father and mother sought to forgive him for his gluttonous and drunken conduct and decided not to bring him to court, they can forgive him.

זקן ממרא שרצו בית דינו למחול לו ⁠– מוחלין לו. וכשבאתי אצל חבירי שבדרום, על שנים הודו לי, על זקן ממרא לא הודו לי, כדי שלא ירבו מחלוקות בישראל. תיובתא.

The third is that in the case of a rebellious elder whom his court sought to forgive for his deviation from their ruling, they can forgive him. And when I came to my colleagues in the South, with regard to two of the cases they agreed with me, but with regard to a rebellious elder they did not agree with me, so that discord would not proliferate in Israel. This supports the opinion of R' Elazar and is a conclusive refutation of the opinion of Rav Kahana.

תניא, אמר רבי יוסי: מתחילה לא היו (מרבין) מחלוקות בישראל, אלא בית דין של שבעים ואחד יושבין בלשכת הגזית, ושני בתי דינין של עשרים ושלשה, אחד יושב על פתח הר הבית ואחד יושב על פתח העזרה, ושאר בתי דינין של עשרים ושלשה יושבין בכל עיירות ישראל.

It is taught in a baraita that R' Yosei said: Initially, discord would not proliferate among Israel. Rather, the court of 71 judges would sit in the Chamber of Hewn Stone. And there were two additional courts each consisting of 23 judges; one would convene at the entrance to the Temple Mount, and one would convene at the entrance to the Temple courtyard. And all the other courts consisting of 23 judges would convene in all cities inhabited by the Jewish people.

הוצרך הדבר לשאול, שואלין מבית דין שבעירן. אם שמעו, אמרו להן. ואם לאו, באין לזה שסמוך לעירן. אם שמעו, אמרו להם. ואם לאו, באין לזה שעל פתח הר הבית. אם שמעו, אמרו להם. ואם לאו, באין לזה שעל פתח העזרה.

If the matter was unclear and it was necessary to ask and clarify it, those uncertain of the halakha would ask the court that is in their city. If the members of the court heard a clear halakhic ruling with regard to that matter, they said it to them, and if not, they would come to a court that is adjacent to their city. If the members of the court heard a clear halakhic ruling with regard to that matter, they said it to them, and if not, they would come to the court at the entrance to the Temple Mount. If the members of the court heard a clear halakhic ruling with regard to that matter, they said it to them, and if not, they would come to the court at the entrance to the Temple courtyard.
