In a 58-page brief, author Fredrik Colting and his legal team disputed that his follow-up to J.D. Salinger's most famous novel was not a sequel, but "a critical examination."

In the new filing, the legal team asks the U.S. Court of Appeals to reverse the court's order enjoining publication of "60 Years Later: Coming Through the Rye." After a hearing last month, federal Judge Deborah Batts ruled that a Swedish author could not publish this book that re-examines the story of "The Catcher in the Rye."

Here's more from the newly-filed appellants' brief: "Had this commentary and criticism been published as an essay, a dissertation or an academic article, there is no doubt that it never would have been enjoined. And banning it, merely because it is presented in what might be a less academic form, not only deprives the Defendants of their rights, but also denies the public the opportunity to read this work and to appreciate the new light it sheds on one of the most famous works of American fiction."
