Which case expanded the reach of the Commerce Clause to include intrastate production that affected interstate commerce?

• A. Wickard v. Filburn (1942)
• B. Lopez v. United States (1995)
• C. McCulloch v. Maryland (1819)
• D. NFIB v. Sebelius (2012)

Answer: (A)

The key idea being tested is how far Congress can regulate activities under the Commerce Clause when those activities are locally performed but have national effects. Wickard v. Filburn expanded that reach by recognizing the aggregation principle: even a farmer’s wheat grown for personal use, if done by many farmers across the country, can substantially affect interstate commerce. The Court held that Congress could regulate this intrastate production because the total amount of wheat not entering the market could alter price and supply conditions in interstate commerce. In other words, the impact is not judged by a single farmer’s activity in isolation but by its potential aggregate effect on the national market. This makes Wickard the best answer here. Lopez later narrowed the scope by requiring a substantial relation to interstate commerce for non-economic activities, McCulloch v. Maryland concerns the broader power of the federal government and supremacy of federal law, and NFIB v. Sebelius centers on using taxing power to enforce an individual mandate rather than expanding intrastate production regulation.
