Restrict Author role from Checking Off Items in a Checklist

I have configured a review that contains a checklist, and I noticed that the Author role can check off items in that checklist. I would like a way to restrict an author from doing this. It seems to defeat the purpose of a checklist if the author can check off items, instead of limiting this capability to reviewers.  I consider this to be similar to restricting an author from closing a review issue.
