 Chief Justice Charles Evans Hughes and Justice Willis Van Devanter subsequently approved this inscription, as did the United States Supreme Court Building Commission which Hughes chaired (and on which Van Devanter served).The architectural firm that proposed the phrase was headed by Cass Gilbert, though Gilbert himself was much more interested in design and arrangement, than in meaning.Thus, according to David Lynn who at that time held the position of Architect of the Capitol, the two people at Gilbert's firm who were responsible for the slogan "equal justice under law" were Gilbert's son (Cass Gilbert, Jr.) and Gilbert's partner, John R. Rockart.
