Over at the Huffington Post,  I scrutinize a recent Legal Memorandum published by the Heritage Foundation on the Prop. 19 ballot initiative.

Here is an excerpt:

The Heritage memorandum claims that if Prop 19 were approved, it would conflict with the federal criminal statute, the Controlled Substances Act and thus “invite litigation that would almost certainly result in [Prop 19] being struck down” as unconstitutional. This legal claim is dead wrong. While it is true that the supremacy clause of the Constitution makes it clear that federal law will override a conflicting state law, that clause simply has no application here. The federal law on marijuana remains in force, but that does not mean that a state government is under any obligation to assist the feds. As the Supreme Court noted in New York v. United States (1992), the state governments are neither “regional offices nor administrative agencies” of the federal government. Let’s take another example. Suppose Congress were to criminalize, say, cotton candy–would California be in violation of the Constitution because its police agents are not now empowered to arrest people producing and possessing cotton candy? No. Nor could Congress compel the California legislature to move against cotton candy producers and consumers. Here again is the Supreme Court: “Even where Congress has the authority to pass laws requiring or prohibiting certain acts, it lacks the power directly to compel the States to require or prohibit those acts.” (New York v. United States, 505 U.S. 144, 166 (1992)). Prop 19 is consistent with the constitutional principle of federalism.
