Branch, a member of the Atlanta-based 11th U.S. Circuit Court of Appeals who is the only judge to publicly join Ho's boycott, said that while universities have been hesitant to punish disruptive students, "fatigue is growing for disruptive protests."

Asked by attendees what it would take for them to end their planned boycott of Yale students, both judges held out the possibility they could abandon it before it takes effect beginning with the class of 2023.

Ho said he understood that Yale appeared to recognize that they "clearly need a massive course correction."

Yale Law School dean Heather Gerken in a letter to alumni on Oct. 12 outlined moves the school has made to "reaffirm our enduring commitment to the free and unfettered exchange of ideas." And she has invited Ho and Branch to speak at another event next year.

"We're watching," Branch said. "We have not only seen some positive developments on campus and campuses, but we've gotten a lot of feedback since we have been here. And I know I'm encouraged by some of the changes that I see that are occurring."
