The Principles of '98 would allow individual states to judge the constitutionality of central government laws and decrees, and could refuse to enforce laws it deemed unconstitutional. Unfortunately, no other states went along and seven state legislatures formally rejected the Kentucky and Virginia Resolutions while three other states expressed disapproval. Several of these states asserted that the federal judiciary, not the states, is the proper forum for interpreting the Constitution. In 1803 the Marbury v. Madison case established the principle of judicial review by the US Supreme Court.
As seen in today's (and many other) US Supreme Court decisions, the restraints on the Federal government have become minimal to nonexistent. Maybe it is time for the Principles of '98 to be formally ensconced in the Constitution. Yes, I know, the 10th Amendment should suffice, but if the arbiter of whether it is sufficient is the US Supreme Court then clearly we need another route. Forget the Tea Party, we need a "Spirit of '98" movement for a constitutional convention to reign in the Federal government.
What you say about the 1798 Virginia and Kentucky Resolutions is interesting. I will have to look into that, I’m not familiar with them.
Failing that, we need to re-pass the 10th Amendment, but this time put it in all capital letters.
