Wikipedia:Articles for deletion/List of current judges of the United States courts of appeals
the nominator claims this is redundant...to 13 separate articles. That's obviously not functionally equivalent to having this information indexed in one place, and I can only see it as useful to the reader to organize those 13 separate sublists together in one list. We can see in one place how many currently serving judges for all the COA were appointed by each president, how many COAs have vacancies, etc. The delete !voters above also do not seem to question this, as they seem to have no issue with the template. Maintenance is not an argument for deletion here as the bench does not change so rapidly that it can't be kept up with. There is also no issue to having both a list and a navigational template cover the same content; see
