From Wiki:
Justice Scalia wrote a separate concurrence that aimed to differentiate the decision from the more recent results of United States v. Lopez and United States v. Morrison. Although Scalia voted in favor of limits on the Commerce Clause in the Lopez and Morrison decisions, he said that his understanding of the Necessary and Proper Clause caused him to vote for the Commerce Clause with Raich for the following reason:
“ Unlike the power to regulate activities that have a substantial effect on interstate commerce, the power to enact laws enabling effective regulation of interstate commerce can only be exercised in conjunction with congressional regulation of an interstate market, and it extends only to those measures necessary to make the interstate regulation effective. As Lopez itself states, and the Court affirms today, Congress may regulate noneconomic intrastate activities only where the failure to do so “could … undercut” its regulation of interstate commerce. ... This is not a power that threatens to obliterate the line between “what is truly national and what is truly local.” Lopez ”
[8] Justice Thomas also wrote a separate dissent, stating in part:
“ Respondent's local cultivation and consumption of marijuana is not "Commerce ... among the several States."
Certainly no evidence from the founding suggests that "commerce" included the mere possession of a good or some personal activity that did not involve trade or exchange for value. In the early days of the Republic, it would have been unthinkable that Congress could prohibit the local cultivation, possession, and consumption of marijuana. ”
and
“ If the Federal Government can regulate growing a half-dozen cannabis plants for personal consumption (not because it is interstate commerce, but because it is inextricably bound up with interstate commerce), then Congress' Article I powers -- as expanded by the Necessary and Proper Clause -- have no meaningful limits. Whether Congress aims at the possession of drugs, guns, or any number of other items, it may continue to "appropria[te] state police powers under the guise of regulating commerce." ”
and further:
“ If the majority is to be taken seriously, the Federal Government may now regulate quilting bees, clothes drives, and potluck suppers throughout the 50 States. This makes a mockery of Madison's assurance to the people of New York that the "powers delegated" to the Federal Government are "few and defined", while those of the States are "numerous and indefinite."[10]
I am no legal scholar, but it appears to me that Scalia may have erred in this case. However, I do believe that both he and Thomas are originalists.
