With financial backing from Hamling, Redrup appealed his case to the Supreme Court where his conviction was overturned by 7-2. The court's final ruling affirmed that written materials that were neither sold to minors nor foisted on unwilling audiences were constitutionally protected, thereby de facto ending American censorship of written material. After this decision, the Supreme Court systematically and summarily reversed, without further opinion, scores of obscenity rulings involving paperback sex books.
