Stanford Law visiting professor Joanna L. Grossman and professor Lawrence M. Friedman explain why the Comstock Act, an anti-vice law passed 150 years ago but never removed from the books, has recently become noticed again with Republicans’ renewed efforts to ban abortion nationwide. Professors Grossman and Friedman describe the law and the man behind the law, Anthony Comstock, and they argue that the so-called ghost law should remain dead.
