This Article proposes a Keynesian inspired approach for the judicial interpretation of economic federalism. Keynesian federalism is premised upon two essential features of Keynesian economics: reactivity and counterbalancing. Federal governments may require increased powers to meet modern challenges, but the judicial rationales and methods of interpretation that permit for this expansion cannot simply be replicated case after case in a way that steadily hollows out regional powers. When a federal government is able to capture increased powers of economic regulation in a federalism dispute, a presumption should arise that in the next major economic federalism dispute a decentralization favouring constitutional interpretation will be privileged.
