In 1995 I accidentally found a "flaw" in the North Dakota state constitution. Since 1889, from the time of drafting its first constitution to the U.S. Congress, its state constitution erroneously directly only state officers of the legislative and judicial branches of state government to take the "oath of office" (required in Article VI, Clause 3 of the U.S. Constitution). It completely leaves out the same requuirement for state officers of the "executive" branch of state government.
Please note that the Enabling Act of Feb. 22, 1889, section 4, required that each of four states (including North Dakota) draft a state constitution "that was not repugnant to the Consitution of the United States and the principles of the Declaration of Independence." The flaw mentioned above was reported by me to a U.S. Attorney; he did absolutely nothing and died of a brain tumor only last year. Any number of ND officials have been told about the "flaw" but they all ignore it to avoid the stigma of letting out the facts that the ND constitution is actually "unconstitutional" in its present format.
This shows the ignorance that exists and the failure to follow the U.S. Constitution. I reported the flaw to parties as listed in Title 18, Section 2382 of the U.S. Code. Nothing happened! The news media also failed to report it, and I have exposed it on three hour-long talk shows...without anyone demanding immediate correction. Yes, the U.S. Constitution needs following!
