Fact pattern

Congress passed the Portable Drone Safety Act, which makes it a federal crime to assemble more than five high-capacity drone battery packs in a 12-month period without a federal license. The statute applies even when the builder buys all parts locally, assembles the packs inside one state, and never sells them across state lines. Congress included findings that homemade battery packs feed an interstate market for unregulated drone equipment and undercut the federal licensing system. Riley, who assembled seven packs in a backyard workshop for neighborhood crop surveys, challenges the statute as beyond Congress's Commerce Clause power.

Quick answer

The statute is likely constitutional because Congress can treat Riley's local assembly of battery packs as economic production that substantially affects a broader interstate market when aggregated. Congress may regulate the channels of interstate commerce, the instrumentalities of interstate commerce, and economic activities that substantially affect interstate commerce. When the regulated conduct is economic in nature, Congress may rely on aggregation and on the Necessary and Proper Clause to support a broader regulatory scheme. But Congress may not use the Commerce Clause to reach every local activity simply by describing remote economic consequences. Cases such as Lopez and Morrison limit federal power when the regulated conduct is non-economic and traditionally local.

Issue

Can Congress regulate Riley's purely local assembly of drone battery packs under the Commerce Clause?

Rule

Congress may regulate the channels of interstate commerce, the instrumentalities of interstate commerce, and economic activities that substantially affect interstate commerce. When the regulated conduct is economic in nature, Congress may rely on aggregation and on the Necessary and Proper Clause to support a broader regulatory scheme. But Congress may not use the Commerce Clause to reach every local activity simply by describing remote economic consequences. Cases such as Lopez and Morrison limit federal power when the regulated conduct is non-economic and traditionally local.

Application

The government has a stronger argument here than it had in Lopez because Riley's conduct looks economic. Riley assembled physical battery packs from component parts, and Congress can characterize that conduct as local production of goods for use in a broader drone-equipment market…
