From the AP:

Two fraternity boys want to make lawsuit against "Borat" over their drunken appearance in the hit movie. The legal action filed Thursday on their behalf claims they were duped into appearing in the spoof documentary "Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan," in which they made racist and sexist comments on camera.

The lawsuit claims that in October 2005, a production crew took the students to a bar to drink and "loosen up" before participating in what they were told would be a documentary to be shown outside of the United States. "They were induced to agree to participate and were told the name of the fraternity and the name of their school wouldn't be used," said the plaintiffs' attorney, Olivier Taillieu. "They were put into an RV and were made to believe they were picking up Borat the hitchhiker."

It will be interesting to see how this plays out.
