Disclosure and the First Amendment: An Explanation of Doe v. Reed for Lay Readers

The Supreme Court recently decided in Doe v. Reed that the First Amendment does not prevent the State of Washington from publicly disclosing the names and addresses of individuals who signed a referendum petition.  This is one of those rare cases where the issues are intellectually appetizing and the Justices are firing on all cylinders.  There were seven opinions each of them fascinating. The majority opinion was written by Justice Roberts and only Justice Thomas dissented.  Justice Scalia concurred in the judgment only.  Justice Alito wrote a concurrence (that should really be a dissent). Justice Breyer wrote a short concurrence, Justice Stevens wrote a concurrence that was joined by Justice Breyer.  Justice Sotomayor wrote a concurrence that was joined by Justices Stevens and Ginsburg. If you're keeping score at home, only Kennedy and Ginsburg did not write on this one.
