They stopped upholding the Constitution in the 1930s when they helped FDR kick the Constitution to the curb. Now they uphold Arbitrary government where they can make shit up as they go along.
Never should have left the gold standard.
...in his seminal 1887 article, “The Study of Administration,” published in the same year that the first modern regulatory commission, the Interstate Commerce Commission, was created, Wilson explained that he wanted to counter “the error of trying to do too much by vote.” Hence, he admonished that “self-government does not consist in having a hand in everything,” while pleading for “administrative elasticity and discretion” free from checks and balances. Not surprisingly, Wilson’s conception of government run by administrative “experts,” unconstrained by popular consent, runs up against the traditional understanding of the Founder’s Constitution, with its tripartite system based on a separation of powers among the legislative, executive and judicial branches.FDR greatly amplified what WW started.
They stopped upholding the Constitution in the 1930s because post-17th Amendment popularly elected senators kowtowed to the wishes of a wildly popular Leftist FDR.
