Gonzales v. Raich
Gonzales v. Raich was a landmark U.S. Supreme Court decision written by Justice John Paul Stevens upholding the application of federal law against marijuana cultivation to a purely local (intrastate) activity in California. By a 6-3 majority, the Court held that the Commerce Clause does grant Congress the authority to prohibit the growing of large amounts of marijuana even if legal under state law. In this case California permitted marijuana growth for allegedly medical purposes.
The Court held that "Congress acted rationally" in declining to adopt a medical-marijuana exception to the generally applicable federal ban on manufacture, possession, and sale. Gonzales v. Raich, 125 S. Ct. 2195, 2211 (2005). "The notion that California law has surgically excised a discrete activity that is hermetically sealed off from the larger interstate marijuana market is a dubious proposition, and, more importantly, one that Congress could have rationally rejected." Id. at 2213.
