Owen J. Roberts, Booth v. United States ex rel. Amidon…
“ It is a contradiction in terms to assert that one who has retired in accordance with the statute may continue to function as a federal judge and yet not hold the office of a judge. The act does not, and indeed could not, endue him with a new office, different from but embracing the duties of the office of judge. He does not surrender his commission, but continues to act under it. He loses his seniority in office, but that fact, in itself, attests that he remains in office. A retired District Judge need not be assigned to sit in his own district. ”
