According to the Wikipedia article about Dan Brown's The Da Vinci Code (emphasis mine),
Possibly the largest reaction [against the novel] occurred in Kolkata, India, where a group of around 25 protesters "stormed" Crossword bookstore, pulled copies of the book from the racks and threw them to the ground. On the same day, a group of 50–60 protesters successfully made the Oxford Bookstore on Park Street decide to stop selling the book "until the controversy sparked by the film's release was resolved". Thus in 2006, seven Indian states (Nagaland, Punjab, Goa, Tamil Nadu, Andhra Pradesh) banned the release or exhibition of the Hollywood movie The Da Vinci Code (as well as the book). Later, two states lifted the ban under high court order.
Which Indian states (the article mentions five states by name) lifted the ban against the novel and when?
