A couple of people, both of whom I respect a great deal, asked me for a First Amendment analysis of the students' trying to orate about the Israel-Palestine conflict at the class party at Berkeley Dean Erwin Chemerinsky's home. Happy to oblige!
[1.] Some people have argued that the party was a public law school function, and thus not just a private event. I'm not sure that's right—but I don't think it matters.
Even if Berkeley law school put on a party for its students in a law school classroom, students still couldn't try to hijack that for their own political orations. Rather, much government property is a "nonpublic forum"—a place where some members of the public are invited, but which is "'… not by tradition or designation a forum for public communication'" (Minnesota Voters Alliance v. Mansky (2018), quoting a leading 1983 case).
