One of the reasons he mentions is the enactment of the Statute of Northampton in 1328, which "declared that no royal command under the Great or the Smaller Seal shall disturb the course of the common law, and that if such command is issued, the judges shall ignore it". (Plucknett, p. 158).

I'm very interested in the historical and political events that served is the process of creating the Statute of Northampton, and the other influences it might had on other judicial matters during those centuries.
