Twenty years later, on August 5, 1886, Congress re-created the Southern District of California by 24 Stat. 308. Erskine M. Ross was appointed Judge of the new district and served until  his promotion to the Circuit Judgeship, when he was succeeded by Olin Wellborn. On March 18, 1966, the Eastern and Central Districts were created from portions of the Northern and Southern Districts by 80 Stat. 75. Specialization.
