Discretion is not deference. That statement may seem obvious to some. To many, however, the two terms are interchangeable. They are not. And the distinction is important, especially now that the Supreme Court has eliminated the deference doctrine associated with Chevron U.S.A., Inc. v. Natural Resources Defense Council. Stated succinctly, deference concerned ambiguous statutory terms or phrases (and implicit grants of authority), while discretion often concerns unambiguously broad statutory terms or phrases (and explicit grants of authority). So even with deference gone, agencies that can point to unambiguously broad terms or phrases in the statutes they administer will retain wide latitude to carry out their missions. 

This working paper summarizes the first empirical study of how major rules, as defined under the Congressional Review Act (CRA), fare in federal court. The study covers each of the 1,870 major rules issued from the CRA’s enactment in 1996 through the end of the Trump Administration. The roughly 24-year period covering four administrations (two from each party) is the longest continuous timespan of any empirical study of agency win rates.

Federal agencies’ cost-benefit analyses do not capture nonhuman animals’ interests. This omission matters. Cost-benefit analysis drives many regulatory decisions that substantially affect many billions of animals. That omission creates a regulatory blind spot that is untenable as a matter of morality and of policy. Valuing animals could have mattered for many cost-benefit analyses, including those for pet-food safety regulations and a rear backup camera mandate. As a sort of “proof of concept,” this Article shows that even a simple breakeven analysis from affected animals’ perspective paints even the thoroughly investigated policy decision at issue in Entergy Corp. v. Riverkeeper, Inc. in an informative new light.

In June 2022, the Supreme Court handed down its landmark decision in West Virginia v. Environmental Protection Agency (EPA), which marked the first time the Court named and expressly relied on the major questions doctrine. This Article surveys how lower federal courts have interpreted West Virginia and applied the major questions doctrine. There is no one major questions doctrine in the lower courts. Judges have taken vastly different approaches to defining and applying the doctrine both within and across circuits. These differences illustrate that many judges may view the doctrine as a little more than a grab bag of factors, which they seem to be choosing from at their discretion. Lower court judges do not appear to be constrained in how they apply the doctrine. In a majority of cases concerning Biden Administration agency actions and executive orders, judges applied the doctrine to reach outcomes that aligned with the political party of their appointing President.

Recently completed and draft guidance is ushering in updated practices for federal benefit-cost analysis. This policy brief examines the impact of two of the most significant upcoming changes: to the discount rate and the social cost of greenhouse gases.
