Huh???
Case law is not an independent body of law decreed by judges. It is the compiled reported decisions of appeals courts and other courts which make case relevant interpretations of the existing law and can be cited as precedents in other similar situations. These interpretations are distinguished from "statutory law" which is the basic statutes and codes (laws) enacted by legislative bodies and "regulatory law" which is regulations required by executive branch agencies based on legislated statutes. Judges can also determine if an act is inconsistent with previous law (or unconstitutional).
The Constitution was created to spell out the limited rights or powers given to the federal government. And it was clearly understood by the founders that the government had no powers that weren't authorized in the Constitution. That includes the judiciary. Making law is the province of the legislative branch. It seems that I read someplace that...All legislative Powers herein granted shall be vested in a Congress of the United States, which shall consist of a Senate and House of Representatives. (Note that it does not say the judiciary and the operant term is "all")
I think I read in that same place "...The judicial Power shall extend to all Cases, in Law and Equity, arising under this Constitution...” not the European Union or United Nations.
For example, the end of slavery and the rights of former slaves and women to vote wasn't legislated by a judge, they are amendments passed by congress and ratified by the states. There is no "abortion right" specified in the constitution, it has been an interpreted portion of the right of privacy that has in turn been interpreted from the 9th amendment of constitution. That amendment says "The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.” The “privacy right” has been judicially interpreted as applying to abortion but doesn’t apply to one’s private internet communications or what data one may maintain on their computer hard drive. They might someday soon. Contrast the clear prohibition on slavery which is clearly defined in the 13th amendment.
The founders intended that if subsequent generations wanted new laws or to change old ones, it would be done by elected representatives, not judges who have no accountability to the people. Take the examples of the Supreme Court deciding in 1973 to protect an interpreted woman's right to privacy in the first trimester of pregnancy and thirty years later to protect the privacy of gay couples from state sodomy laws. Regardless of how you may value these interpretations, they could be eroded, changed or overturned by a future court with a different view of what is "indispensable to the dignity and happiness of a free man." This is one of the core flaws in “judicial activism”. What one judge gives, another can take away. A later judge may see that life begins at conception and the right to life of a fetus trumps the privacy rights of a mother. A hundred and fifty years from now, abortion may be popularly viewed as abhorrent as slavery is today (I hope so). That’s why you pass laws and don't rule by judicial fiat.
Following the example, the founders provided we could amend the Constitution to create a right of privacy that would be beyond the reach of any future court or Congress. Our system is supposed to be based on laws, not men. The founders provided that if you didn't like the constitution, change it. "...The Congress, whenever two thirds of both Houses shall deem it necessary, shall propose Amendments to this Constitution, or, on the Application of the Legislatures of two thirds of the several States, shall call a Convention for proposing Amendments, which, in either Case, shall be valid to all Intents and Purposes, as Part of this Constitution..." And that's certainly happened. Those of us that believe in the constitution contend that it has orderly processes for change and history would indicate that’s happened and what should happen. I personally don’t support one judicial activist, left or right, to establish law over the process of the legislative or executive branches and I think that is the “conservative” position that many of us have. Just as conservatives believe in self-determination and wanting the government out of our lives to the greatest extent possible while still maintaining an orderly society.
The government has no business in my bedroom, spending my granddaughter’s taxes, spying in her lunchbox or telling my church which beliefs they must disregard. Nobody is better equipped to run my life than I am and certainly not some idiot in Washington.
“A wise and frugal government, which shall restrain men from injuring one another, which shall leave them otherwise free to regulate their own pursuits of industry and improvement, and shall not take from the mouth of labor the bread it has earned. This is the sum of good government, and this is necessary to close the circle of our felicity.” Thomas Jefferson, First Inaugural Address.
