Although the Supreme Court has not invalidated a private delegation since 1936, debate around the constitutionality of private delegations has persisted among scholars and courts. Circuit courts are split regarding the constitutionality of the private delegation in the Horseracing Integrity and Safety Act (“HISA”). The debate regarding the constitutionality of HISA is rooted in a broader discussion about the legality of private delegations in relation to separation of powers principles. There are two principal theories of separation of powers: functionalism and formalism. The functionalist approach focuses on how government works in practice, weighing the overall balance of power between branches of government. The formalist approach focuses on the text of the Constitution and endorses strict separation of roles for each branch of government. This Contribution argues that courts should adopt a functionalist approach to evaluating private delegations in order to preserve the flexibility and expertise necessary for effective modern governance, while ensuring political accountability and preventing self-interested regulation by private entities.
