What is the function of the 10th Amendment to the US Constitution, and how does it relate to the rest of the Constitution?

One morning the President wakes up with a bit of a gas attack. “I don’t feel very cooperative this morning,” he says, downing a couple of antacids, “I think I’ll just forget about habeus corpus today.”

It is this type of personal, subjective approach to civil rights and the Constitution for which I think the 10th Amendment was written. Yet there are those who disagree. I’d love to hear from you! : )
