Did both Davis v. Beason and Gitlow v. New York mention the First Amendment in their case? 
Davis v. Beason: Davis v. Beason, 133 U.S. 333 (1890), was a United States Supreme Court case affirming, by a 9-0 vote, that federal laws against polygamy did not conflict with the free exercise clause of the First Amendment to the United States Constitution.
