Sanhedrin 26 - January 12, 12 Tevet

Those who sell produce during the Sabbatical year are disqualified from testifying. Rabbi Shimon (in the Mishna) explains that initially, these people were called collectors of Sabbatical produce. However, when tax collectors (anasim) became more numerous, the term changed to "sellers of Sabbatical produce." The Gemara presents two interpretations of this unclear passage, with the first interpretation being rejected. Reish Lakish was following two rabbis who were traveling to Asya to intercalate the year, as he wanted to observe their process. During their journey, they encountered people plowing and harvesting during the Sabbatical year. When Reish Lakish questioned why the rabbis weren't stopping these apparent violations, they offered possible explanations for how each person's actions might be permissible. Upon reaching their destination, the rabbis went to the second floor to deliberate about the intercalation. They climbed up using a ladder and immediately removed it to prevent Reish Lakish, whom they considered bothersome, from following them. Reish Lakish later complained to Rabbi Yochanan, declaring the rabbis to be a kesher reshaim (conspiracy of wicked people) who should not participate in the year's intercalation. The Gemara then traces the origin of the term kesher reshaim through stories about Shevna, who served as Hizkiyahu's steward. Rabbi Abahu, citing Rabbi Elazar, states that the court must publicly announce when someone is found to be disqualified from serving as a witness. Until such an announcement is made, the witnesses retain their qualification to testify. There is a specific debate regarding whether this announcement requirement applies to shepherds. Regarding wrongdoers such as those who accept charity from gentiles, engage in forbidden sexual relationships, or eat from fields during harvest season - there is a discussion of their eligibility to testify. Rav Nachman presents his views on these three cases, and the Gemara either restricts the scope of these rulings or presents opposing viewpoints.
