By way of background, there are journals in which the editor - as in, the person who contacts referees, guides the review process, and makes a decision is unknown to the corresponding author. Communication with the author is solely through a named, administrative editor who does not have any decision making authority, and is merely a conduit for the editor's decisions.
What could be the rationale for such a system? Of course, one can understand the importance of referee anonymity so they can comment freely on the merits of a submission. However why should editors remain behind a veil of anonymity?
