Supreme Court Rules Federal Drug Rules Preempt State Laws
The U.S. Supreme Court yesterday ruled 5-4 that in cases involving generic drugs, federal laws take precedence over an individual’s right to sue in state courts. The case, Mutual Pharmaceutical Co., v. Bartlett, overturned lower-court rulings in favor of the plaintiff, who sued the generic drug manufacturer Mutual Pharmaceutical — now part of Sun Pharmaceutical Industries…
