The Statutory Separation of Powers

The separation of powers forms the backbone of our constitutional democracy. But it is also a guiding principle in sub-constitutional domains. This Article argues that Congress constructs statutory schemes of separation, checks, and balances through its delegations to administrative agencies. This statutory separation of powers may be seen clearly in the simultaneous legislative creation of the independent Federal Energy Regulatory Commission (FERC) and the executive Department of Energy (DOE). Like its constitutional counterpart, the statutory separation of powers seeks to prevent the dominance of faction and create policy stability. But separating and balancing statutory authority is a delicate business subject to challenges of imprecise allocation, lopsided aggrandizement, and infrequent adjustment. The relationship between FERC and the DOE demonstrates these challenges, which have allowed the DOE to weaponize statutory checks and balances in its pursuit of policy dominance. The article concludes with recommendations for how Congress, the judiciary, and agencies themselves might mitigate these tendencies and preserve the statutory separation of powers as a meaningful safeguard against the perils of concentrated policymaking authority.
