Several weeks ago, under the title "Is It Permissible?" I discussed how Congress systematically abuses the Constitution's "welfare clause" to control our lives in ways that would have been an abomination to the Framers. Quite a few readers pointed to my omission of Congress' companion tool to circumvent both the letter and spirit of the Constitution, namely the "Commerce Clause."
The Constitution's Article I, Section 8, paragraph 3 gives Congress authority "To regulate Commerce with Foreign Nations, and among the several States, and with the Indian Tribes." During the war, the 13 colonies formed a union under the Articles of Confederation (1778) whereby "Each state retains its sovereignty, freedom, and independence, and every power, jurisdiction, and right, which is not by this Confederation expressly delegated to the United States, in Congress assembled." The Treaty of Paris (1783) that ended the war between the colonies and Great Britain recognized 13 sovereign nations.
A key failing of the Articles of Confederation was the propensity of states to erect protectionist trade barriers. When the Framers met in Philadelphia in 1787 and wrote the constitution that governs us today, they addressed that failure through the commerce and the privileges and immunities clauses that created a national free-trade zone.
Thus, the original purpose of the Commerce Clause was primarily a means to eliminate trade barriers among the states. They didn't intend for the Commerce Clause to govern so much of our lives.
Indeed, as James Madison, the father of our Constitution, explained, "The powers delegated by the proposed Constitution to the federal government are few and defined. Those which are to remain in the State governments are numerous and indefinite."
For most of our history, the Courts foiled congressional attempts to use the "Commerce Clause" to sabotage the clear meaning of the Constitution, particularly the Ninth and 10th Amendments. The courts began caving in to congressional tyranny during the 1930s. That tyranny was sealed in 1942, by a little known U.S. Supreme ruling in Wickard vs. Filburn.
Filburn was a small farmer in Ohio. The Department of Agriculture had set production quotas. Filburn harvested nearly 12 acres of wheat above his government allotment. He argued that the excess wheat was unrelated to commerce since he grew it for his own use. He was fined anyway. The court reasoned that had he not grown the extra wheat he would have had to purchase wheat -- therefore, he was indirectly affecting interstate commerce.
