As businesses have scrambled to obtain compliance with the California Consumer Privacy Act (CCPA) in recent months, questions surrounding its constitutionality have arisen. As a broad, sometimes unclear state law that imposes significant obligations on businesses around the country, CCPA may be ripe for legal challenge. The strongest bases for such challenges appear to be: (1) that CCPA violates the “Dormant Commerce Clause”; and (2) that CCPA is impermissibly vague.

Dormant Commerce Clause

The burden that CCPA imposes on out-of-state economic activity may place it in violation of the Dormant Commerce Clause, a legal doctrine created out of the Commerce Clause of the US Constitution. The Commerce Clause allows the US Congress to regulate interstate commerce; from this grant of power, courts have inferred a limitation on the authority of states to regulate interstate commerce, a doctrine coined the Dormant Commerce Clause. On this basis, courts will strike down state laws that explicitly discriminate against out-of-state actors or that regulate activity that occurs entirely outside of the state. In addition, the Dormant Commerce Clause prohibits laws that do not explicitly discriminate against out-of-state economic interests if the effect of a law is to unduly burden interstate commerce. If a state law does unduly burden out-of-state interests, a court will typically balance the burdens imposed on interstate commerce against the benefits the law creates for the state to determine whether or not the law should be upheld.
