In the context of disqualifying judges, Resh Laskish expresses great respect for Rabbi Meir, despite his unusual opinion. Which deference the Gemara seems to query. So, how did the sages relate to each other? How was Baylonia different? Plus, drawing connections between arrogance and poverty, and the Torah scholars in Babylonia vs. Persia (Elam). Also, a new mishnah: litigants can accept otherwise people who are not valid to be judges. But whether they are can change their minds with regard to that acceptance is a machloket. And the Gemara discusses the timing of that machloket - when can a litigant change his acceptance? Plus, a list of the disqualifiers.
