How would you know that if you don't know what they relied upon?
How about just reading the 10th and getting back to me? The point is, the fedgov decided a long, long time ago that they did not have to bother with that pesky 10th Amendment. You can base a legal decision upon previous decisions built upon that foundation of sand, but it still is not rooted in the Constitution, and is therefore a usurpation. But you're a liberal, so I don't expect you to understand the concept - you applaud usurpation masked as progressivism.
