Chris, when using anagrams or charades there are bound to be some similarities. It has usually been the case that the judge or voters decide. Most setters will defer to that as well if a later entry is similar. I've noticed that some setters don't read through previous entries, and some do. To each their own. I feel that there are enough checks and balances to take care of when these situations inevitably arise. Often a setter who hasn't noticed a previous similar entry spots it during voting anyway. My own judgment in this particular competition is that while the anagrams or charades may be the same, the surfaces are different enough. However, "My Sweet Lord" was clearly plagiarism.
