With regard to the Festival day of Rosh HaShana that occurs on Shabbat, in the Temple they would sound the shofar as usual. However, they would not sound it in the rest of the country outside the Temple. After the Temple was destroyed, Rabban Yoḥanan ben Zakkai instituted that the people should sound the shofar on Shabbat in every place where there is a court of twenty-three judges. Rabbi Elazar said: Rabban Yoḥanan ben Zakkai instituted this practice only in Yavne, where the Great Sanhedrin of seventy-one judges resided in his time, but nowhere else. They said to him: He instituted the practice both in Yavne and in any place where there is a court. The mishna adds: And Jerusalem in earlier times had this additional superiority over Yavne after Rabban Yoḥanan ben Zakkai instituted this practice, for in any city whose residents could see Jerusalem and hear the sounding of the shofar from there, and which was near to Jerusalem and people could come to Jerusalem from there, they would sound the shofar there as well, as it was considered part of Jerusalem. But in Yavne they would sound the shofaronly in the court itself, not in the surrounding cities.

At present, while the Temple is destroyed, wherever a court whose judges received semichah in Eretz Yisrael permanently holds sessions, the shofar is sounded on the Sabbath. Furthermore, the shofar is sounded on the Sabbath only in a court that has sanctified the new moon. However, the shofar will not be sounded in other courts, even though their judges have received semichah. Also, the shofar is sounded only in the presence of a high court.
It may be sounded during the entire time they are in session. Even after they have begun preparing to rise - as long as they have not risen - the shofar may be sounded before them. However, outside the court, the shofar may not be sounded.
Why is the shofar allowed to be sounded in the court? Because the court is scrupulous [in the observance of the mitzvot] and, in its presence, those who blow the shofar will not carry the shofar in the public domain, for the court will warn the people and inform them.
