An ISBN isn't necessary for copyright to exist, however for a successful claim of copyright (including punitive as well as compensatory damages) to be made, the publication has to be registered with the relevant national repository. All an ISBN does is (theoretically) identify a specific edition/format of the publication, and there are known cases of single ISBNs being (incorrectly) used for multiple books.
