Not so for practical purposes. In FDR's day the SCOTUS found that a farmer growing wheat, for his own consumption on his own farm, and the farm was totally enclosed within one state, was interstate commerce. This was done to advance the authority of the federal government in support of the new deal. The courts are corrupt and co-opted by the radical left. They are the hammer with which the destruction of the United States was effected. Presently, the constitution of the United States no longer applies to it's government and the power of the government is essentially unlimited. Even the free election process has been destroyed by leftist voter fraud. The restoration of constitutional limits upon the federal government will not be accomplished by the courts and is very unlikely to be accomplished by the ballot box. IMHO, unless we are incredibly lucky, for those of us on FR our choices will devolve to slavery or insurrection.
I'm well aware of that. But I guess it depends on ones notion of "practical".
A Law professor at the time wrote that the decision "cannot pass the giggle test."
It has been open season on our liberties and Constitution ever since.
