Wickard marked the beginning of the Supreme Court's total deference to the claims of the U.S. Congress to Commerce Clause powers until the 1990s. The Court's own decision, however, emphasizes the role of the democratic electoral process in confining the abuse of the power of Congress: "At the beginning
Chief Justice Marshall described the Federal commerce power with a breadth never yet exceeded. He made emphatic the embracing and penetrating nature of this power by warning that effective restraints on its exercise must proceed from political rather than from judicial processes." Critics have noted that under
Wickard there is "no distinction between 'interstate' and 'intrastate' commerce to place any limits on Congress' authority under the Commerce Clause", and that it allows regulation of activity that is generally not considered commerce. According to Earl M. Maltz,
Wickard and other New Deal decisions gave Congress "the authority to regulate private economic activity in a manner near limitless in its purview." That remained the case until
United States v. Lopez (1995), which was the first decision in nearly six decades to invalidate a federal statute on the grounds that it exceeded the power of the Congress under the Commerce Clause. The opinion described
Wickard as "perhaps the most far reaching example of Commerce Clause authority over intrastate commerce" and judged that it "greatly expanded the authority of Congress beyond what is defined in the Constitution under that Clause." In
Lopez, the Court held that while Congress had broad lawmaking authority under the Commerce Clause, the power was limited and did not extend so far from "commerce" as to authorize the regulation of the carrying of handguns, especially when there was no evidence that carrying them affected the economy on a massive scale. (In a later case,
United States v. Morrison, the Court ruled in 2000 that Congress could not make such laws even when there was evidence of aggregate effect.) The Supreme Court has since relied heavily on
Wickard in upholding the power of the federal government to prosecute individuals who grow their own
medicinal marijuana pursuant to state law. The Supreme Court would hold in
Gonzales v. Raich (2005) that like with the home-grown wheat at issue in
Wickard, home-grown
marijuana is a legitimate subject of federal regulation because it competes with marijuana that moves in interstate commerce: In 2012,
Wickard was central to arguments in
National Federation of Independent Business v. Sebelius and
Florida v. United States Department of Health and Human Services on the constitutionality of the individual mandate of the
Affordable Care Act, with both supporters and opponents of the mandate claiming that
Wickard supported their positions. ==See also==
