On December 30, 1922, Atwell was nominated by President Warren G. Harding to a new seat on the United States District Court for the Northern District of Texas created by 42 Stat. 837. He was confirmed by the United States Senate on January 9, 1923, and received his commission the same day. He served as chief judge from 1948 to 1954, assuming senior status on December 31, 1954. Atwell continued to serve in that capacity until his death, in 1961.
