So What is the Law of the Land?

THE LAW OF THE LAND
(See § 22 of California Civil Code):

The highest law of the land is the U.S. Constitution;
Underlying the U.S. Constitution are the State Constitutions;
Underlying the Constitutions is English Common Law.
Higher law overrules lower law. Lower laws may not infringe or contradict or be in conflict with higher laws. Laws must be ratified by a two thirds majority of representatives of "We the People".
