The White House recently announced that President Trump had nominated Judge A. Marvin Quattlebaum to a seat on the Fourth Circuit Court of Appeals. Judge Quattlebaum currently sits as a federal district judge in South Carolina–a position he has held for only two months.
There is nothing inherently wrong with seeking to promote* Judge Quattlebaum to the appellate bench. But choosing a sitting district judge will once again create a vacancy in South Carolina, and that vacancy may take much longer to fill. Politics may well dictate filling appellate benches, especially in election years. But the trial courts, the place where the public most closely and commonly interacts with the judicial system, risk becoming the forgotten child. They deserve to filled as rapidly, and with as much care, as do appellate court vacancies.
* Many on the federal district bench would quibble with this term: the trial judges are the real judges! I use it here only in the sense that the Fourth Circuit is higher in the federal hierarchy.
