 "The Government of England", a work on British constitutional law, was praised by Dicey as teaching him more about the way in which early constitutional principles were developed than any other work.Hearn's last major project was an attempt to codify Victorian law, which resulted in a book published on its theoretical basis, "The Theory of Legal Duties and Rights", and a draft bill which ultimately entered parliament for consideration.The codification, influenced by positivist and utilitarian thought, was "based on a Benthamite-Austinian view of jurisprudence".
