@ebrown p,
Thats enabling rules for a great wide arena of stuff e. The Code of Federal Regs is where the actual rules reside, not the Constitution. Otherwise it sounds like the Constitution is like Genesis in that all contingencies were pre thought of in the 1780's.
Its Just like 40 CFR covers all nuclear regs, Something of which the Constitution is silent. The Constitution limits and empowers, it doesnt regulate.
