Dual systems

So, I learned yesterday that, in addition to civil and criminal law, which is based on statutes and codes, there is also common law, which may or may not have precedents in cases, or case law. Stare decis refers to precedents established in the common law. So, when applicants for the SCOTUS pledge to respect stare decis, they are referring to something that can be supplanted at any time by legislation.

The reason Roe v. Wade was found to have been prongly decided is basically because the U.S. legal system does not recognize, much less protect, human rights

Civil rights = civic obligations
Property rights = ownership obligations
Natural rights = who know?
Presumption of probity = nobody cares
