Is it safe to say that the interpretations you call for.....change over time ?
Not that it negates your point.
Just asking.
Hell yes. Obviously it changes over time. The authority wielded by the courts is that of the people. And we are the People. Thus, any decision made by the courts utilizing our authority are AT LEAST as authoritative as those made by the courts empowered by past generations. I'd argue, we're even more authoritative. As the law created by the living trumps that created by the dead in almost every meaningful way.
Some of the founders, Madison and Jefferson in particular, believed that the constitution should mean whatever they believed it was supposed to. But the interesting part? How little regard the rest of the founding fathers gave that perspective. Madison was lamenting in a fishing subsidy bill debate about how the general welfare clause wasn't being used in the manner he envisioned it....
......only three years after the constitution was ratified.
The Bank of the United States, opposed by both Madison and Jefferson, was easily passed in the very first session of congress. With the founders demonstrating with their actions that the Constitution meaning wasn't bound to what some at the Constitutional Congress believed it was.
And realistically, that's the only way the document ever could be interpreted. As it must go through people to be enacted. And OF COURSE they are going to interpret the document as aligning with their own beliefs and interpretations. Often those interpretations are based on the times they live in. The USSC explicitly upheld interracial sex bans in the 1870s....using some of the most bigoted, racist reasoning you've ever heard. Bigoted and racist by our standards anyway. But there's no way that the USSC would do something similar today. I doubt even Scalia would join such a move.
Yet the constitution is the same. The changes made from 1870 to today are inconsequential in terms of interpreting bans on interracial sex. But the times have changed. The men and women weilding power have changed. The sentiment of the people they represent has changed. And the interpretations of the constitution change with it.
