The suit, aimed at ALF and other groups, is to stop what they say are "terrorist and violent" attacks against researchers.
UCLA administrators are taking on some animal rights activists. The university has gone to court to get a restraining order against some animal rights groups.
Activists are accused of harassing UCLA researchers who conduct experiments using animals.
Lawyers for UCLA say that the harassment has become violent in recent years and wants it to stop. A lawyer for the animal rights activists say they haven't been doing anything illegal.
I'm not sure how that "we haven't been doing anything illegal" thing will fly.
