For the second time this year, the U.S. Supreme Court has refused to hear a challenge by Johnson & Johnson in litigation over its talcum powder products, which women have claimed cause ovarian cancer.

In Johnson & Johnson v. Fitch, the company challenged a Mississippi Supreme Court decision that a state consumer protection law required an ovarian cancer warning label even though the U.S. Food and Drug Administration had concluded earlier that evidence did not justify a warning, according to J&J counsel E. Joshua Rosenkranz of Orrick Herrington & Sutcliffe.
