he court only has that power if it is in compliance with the letter and intent of the Constitution.
The letter and intent of the constitution.....according to who? This is where things get a little muddy.
As the constitution contains quite a bit of ambiguity and room for interpretation. For example, what is 'probable' cause? What are 'arms' per the constitution? What does 'regulate' mean? What is 'unreasonable' search and seizures? What is 'natural born'?
And that's not even taking into account the implied powers that the federal government possesses, but that the constitution makes no mention of.
And of course, when you're dealing with rights, more than one person has them. So you often have competing rights. My right to free speech in screaming 'fire!' in a crowded theater vs. your right to life and my immediate endangerment of it. The degree of regulation of say, arms. Are they only muskets, as existed in the founders era? Do they include only commonly held arms by the public today. Or do they encompass all weaponry, granting individual citizens a protected right to own and use nuclear weapons, land mines and 50 caliber machine guns?
The courts are the body delegated the authority to make these judgment calls. That you may disagree with their judgment doesn't make it any less authoritative. Nor does the court lose its power because you decide that their judgment wasn't with the 'letter and intent of the constitution'. Or if I do.
Though if enough of us disagree, we can override the courts through the nomination process over the long term......or via amendment in the shorter term. Though neither is particularly easy. Nor should be. The beauty of our system is the difficulty of the consolidation of power.
The invention of the powers in the "General Welfare" clause was a huge violation of that concept.
Its the recognition of implied powers....which you have already acknowledge exists. The issue is then that of degree. Where you believe that the courts have acknowledged too many implied powers. Not that implied powers don't exist. Nor that the federal government has no power save those expressly enumerated.
And on issues of degree, I may be inclined to agree with depending on what we're talking about.
