Historical Trivia (Middle District of Tennessee Edition)

What would happen if, say, a state seceded from the Union but its federal judges refused to resign? They'd still be federal judges, right? Actually, this happened once:

"When Tennessee seceded on May 7, 1861, the Confederate Congress approved Jefferson Davis' nomination of [federal District Judge] Humphreys to be judge of [the] Confederate court for Tennessee. However, unlike the other 13 Federal judges in the South, who joined the Confederacy, Judge Humphreys failed to resign from his position as Federal district judge. This presented the Union government with the thorny problem of how to deal with Judge Humphreys. Because President Lincoln was operating on the assumption that the Union was indestructible, it was necessary to impeach Humphreys before another judge could be appointed to the position. He was impeached by the House and convicted by the Senate on six counts that included advocating and helping to organize rebellion against the United States; refusing to hold Federal court sessions after July 1861; and, while acting as judge, arresting certain U.S. citizens, including William G. Brownlow, who later became Governor of Tennessee during Reconstruction. After conviction by the Senate, Judge Humphreys was removed from office and disqualified from holding future office in the United States Government."
