Tommy Spitaletto (Partner-Dallas, TX) represented an English company that provided testing services for nutritional supplements in the United States. The client was sued by a plaintiff who had filed at least 10 cases and appeals in different state and federal courts, together with Major League Baseball, most of the MLB teams, various testing laboratories and others. In his 100-page complaint, the plaintiff claimed to have created a nutritional supplement containing an insulin-growth factor, and sued our client regarding advertising for testing of banned substances – asserting fraud, violations of the Lanham Act for false advertising, RICO violations, unjust enrichment and mental anguish. After extensive briefing with a joint defense group, the court dismissed all of the plaintiff’s claims with prejudice. Based on multiple prior lawsuits against other defendants, the court also deemed the plaintiff a “vexatious” litigant, and enjoined him from filing any new pleadings or cases in the Southern District of Texas unless he obtains advance permission from the Chief Judge.
