Sotomayor, who has dissented in major cases including the abortion decision as the court's 6-3 conservative majority has become increasingly assertive, described herself as "shell-shocked" and "deeply sad" after that term ended in June.
The court's current term, which began in October, could be just as consequential as its previous one.
In October, conservative Justice Samuel Alito, who authored the Dobbs opinion, warned against questioning the court's integrity.
At Wednesday's conference, Chemerinsky noted that he had never before seen his law students so discouraged about the Supreme Court.
Sotomayor, appointed to the court by Democratic former President Barack Obama in 2009, expressed optimism that the direction of the court will change in the future.
