I've noticed with increasing frequency that there are some closed questions that I cannot delete (as in, there is no "Delete" link):

I am unable to determine what the criteria are for whether I can (vote-to-) delete the question. My understanding was that as a "Trusted User" I can delete even new questions (though the examples above are all new).
Does anyone know why I can delete some but not others?
