The quote above is a a load of crap, pardon my French, in my opinion.Common Law: The courts have developed common law over time based on principles of justice, equity and the morals and ethics of the time. Scholars collect the common law into volumes called the Restatements.
The development of Common Law was barbaric, haphazard, and accidental at times. It was just as much about politics as it was about "justice".
Justice, being a legal term of art, means rendering unto each man his due in this context. These men shall possess different statuses within the society, therefore the respective "justice" for each class will differ.
Common Law developed into monopoly law for the king after 1069 A.D.
Common Law became about sovereign prerogatives.
I can't believe the truth is written here .Statutory Law: Congress or state legislatures write statutes, which results in laws that are primarily influenced by special interest groups. A body of law is sometimes collected in a model code or uniform statute, such as the Uniform Commercial Code or the Model Penal Code.1
Thanks for the contribution.
