A commercial barrister, he was a Justice of the High Court from 1925 to 1932, when he was directly promoted to the House of Lords as a law lord. Robert Stevens described him as "one of the few significant British appeal judges of the twentieth century."

He was called to the bar in 1900 by the Inner Temple and practiced at the commercial bar, having joined the chambers of Thomas Edward Scrutton.
