Last month I posted about how Into The River had been banned in New Zealand; it was "illegal to supply the book to anyone or to display the book in or within view of a public place."
As of October 14, this ban has been lifted, and the book is once again classified as "unrestricted". You can read the 21-page decision (pdf) if you like; I only skimmed it. It seems that the President of the Film and Literature Review Board dissented, but majority ruled and the book can once again be read by humans of all ages. Take a look at this excellent site for a complete case study.
I received my copy just yesterday, and do still plan to read it :-)
