In re Ephedra Products Liability Litigation
Plaintiff Sharon Stafford sued Universal Nutrition Corp. (UNC), MTM Marketing and Consulting Inc. (MTM), and Robert Michnal, alleging their ephedra product, ThermoSlim, caused her 2002 stroke. Defendants moved for summary judgment, contesting causation and personal jurisdiction, and seeking to exclude the testimony of treating neurologist Dr. Wesley Dennis. The court denied the summary judgment motions, finding sufficient evidence for a jury to infer causation under Texas law, which governs the case. The court also found personal jurisdiction over all defendants. Dr. Dennis's specific causation opinion was admitted, though other opinions were excluded.
