As of CakePHP 2.3 - Out of Range page requests will throw an exception.

However the documentation is not correct in saying that the paging parameters will be available to you in $this->request->params['paging'], because those are defined after the exception is thrown. (This problem has been fixed in CakePHP 2.4.x two months ago)

So, to get the effect you want you can do something like this in your controller:

public function index() {
    try {
        $paginatedData = $this->Paginator->paginate();
    } catch (NotFoundException $e) {
        //get current page
        $page = $this->request->params['named']['page'];
        if( $page > 1 ){
            //redirect to previous page
            $this->redirect( array( "page" => $page-1 ) );
        }else{
            $paginatedData = array(); //no data to paginate so use empty array()
                                      //you will have to check for this in the view and no longer display the pagination links, since they will NOT be defined
        }
    }
}
