Why was importing diaphragms against the law?

Did Margaret Sanger and others get in trouble for importing diaphragms?
Margaret Sanger and her sister, Ethel Byrne, were arrested for breaking a New York state law that prohibited distribution of contraceptives. Sanger was also charged with running a public nuisance.
