This is an example of the importance of appointing justices that will defend the constitution, and not use their office as a means to legislate.
State's powers vs. federal powers was the reason for the constitution to begin with. Too much power in the states and the union would fall apart, as it nearly did under the original Articles of Confederation. The constitutional system enacted in 1787 has served us well, for the most part, ever since.
Unfortunately, members of congress are not familiar with the document, nor it would often appear, is the Supreme Court.
The bill of rights was added after the constitution was enacted, and basically provided for the protection of the rights of the citizens against infringment by the feds. The 14th ammendment applied most, but not all, of those same restrictions on the states.
The part of the constitution that seems to be causing the most difficulty these days are the "powers" (commonly mistaken as rights) the feds are using to the detriment of the states and of the people. Most of these derive from the federal government's "implied powers."
An "implied power" would be the establishment of a federal bank to aid in the collection of taxes and the disbursment of those funds by the federal treasury. The treasury is perfectly legit, and the court ruled that a government bank was legit as well, because it was necessary to carry out the actions required of the treasury.
These "implied powers" combined with "interstate commerce" bring the federal government into just about anything we, as citizens, do on a daily basis. An example, when the constitution was ratified, it was generally recognized that policing and crime control was the responsibility of the states. Sure there were federal felonies, such as treason, but they were very limited in number and generally carried the death penalty. Today you have numerous federal police agencies and they regulate many of the same things as the states.
An example: Federal law allows the FBI to investigate bank robberies. Show me one state that does not have a law against this. Shouldn't the states prosecute bank robbers?
I can understand some federal agencies under implied powers. After all, if there were no enforcement how many of us would pay the egregious taxes congress levies? But some of them seem to be on rather shaky ground.
How far can we stretch interstate commerce and implied powers? I think we have reached the limit as the court has begun to strike down some of the laws congress has been passing using their interstate commerce powers. The Brady Bill requiring sheriff's to perform certain acts and the gun free school zones come to mind.
BTW: Don't take this as a blanket tirade against federal law enforcement. Many of these agencies perform jobs that state and local agencies could never accomplish, such as the FAA guys who act as counter-terrorist agents on US flag air carriers.
The constitution and it's continuous evolution is a fascinating subject. It's a darn shame that more of our lawmakers haven't a basic understanding of the document.
