Lawprof Eugene Volokh has a good post on the "abortion art" controversy at Yale. (For background, see here.) As he points out, since "Yale is a private university, ... the issue here is properly one of professional principles of academic freedom rather than of the First Amendment as such."
The latest news is that Yale is saying it will not let her show the work unless she admits it was a hoax all along.
UPDATE: Randy Kennedy has more in this morning's New York Times: "Yale University said on Monday that it would not allow a senior to participate in a campus art exhibition unless she made a written statement that her 'performance,' in which she repeatedly inseminated herself and then induced miscarriages, was a fiction that she had concocted."
