Heagney, et al. v. John Paul Mitchell Systems — 9th Cir. (argued August 31, 2026)
The Ninth Circuit hears Heagney versus John Paul Mitchell Systems. Consumers allege that the company's ‘no animal testing’ labels misled California buyers. A district judge certified a purchaser class. This appeal asks whether exposure to the label, its importance to a reasonable buyer, and damages can be addressed with common proof across the class. It does not decide whether the labels were false.
