Sanhedrin 87: Disagreeing Rabbis Aren't Rebellious Elders (unless they cross that line)

The Gemara specifies what kinds of cases need to be brought before the experts on the court. Plus, discussion of "going up" to the land of Israel, and then Jerusalem, for that expertise. Plus, a return to the case of the rebellious elder who goes against the teachings coming from the Sanhedrin in Jerusalem. Also, Rav Pappa parses each detail of a baraita, quite thoroughly, to line it up with Rabbi Meir's approach on the rebelliious elder and also connect to other disputes.
