A couple of weeks ago I discussed a lawsuit filed by StemExpress — a broker of fetal tissue — against the Center for Medical Progress, the group at the heart of the ongoing video-based criticism of Planned Parenthood. I noted that a judge of the L.A. County Superior Court had issues a temporary restraining order preventing CMP from releasing a video of a meeting it had with StemExpress executives, and expressed some concern about the reasoning and how the ruling was constitutional under the prior restraint doctrine. Eugene Volokh's take was clearer and less prone to outbursts of profanity.
StemExpress' initial success now appears unlikely to continue. CMP has filed a well-drafted anti-SLAPP motion attacking the StemExpress complaint. I've explained how anti-SLAPP motions work before. If you're being sued for speech, and you believe the speech is protected, you can file the motion, lay the factual framework for the speech being protected, and force the plaintiff to come forward with admissible evidence showing it could plausibly succeed on its claims. Moreover, an anti-SLAPP motion halts discovery absent a special order of the court.
