The Ncaa's Challenge In Determining Nil Market Value, Meg Penrose Jan 2024

The Ncaa's Challenge In Determining Nil Market Value, Meg Penrose

Faculty Scholarship

This Article proceeds in three parts. Part II discusses the changes that NIL has wrought in college athletics. It briefly explains collectives and their impact on NIL. Part III discusses the impossibility of limiting athletes’ “fair market value” given market value depends on what the market is willing to pay. Congress has failed to pass national legislation. Yet the mosaic of state laws is simply unfit to stand in for national legislation. And, following multiple litigation losses, the NCAA cannot be trusted to “value” the athletes themselves. Market value, if one is to be established, must be uniform and assessed …

The Major Questions Doctrine At The Boundaries Of Interpretive Law, Daniel E. Walters Jan 2024

The Major Questions Doctrine At The Boundaries Of Interpretive Law, Daniel E. Walters

Faculty Scholarship

The Supreme Court’s apparent transformation of the major questions doctrine into a clear statement rule demanding clear congressional authorization for “major” agency actions has already had, and will continue to have, wide-ranging impacts on American public law. Not the least of these is the impact it will have on the enterprise of statutory interpretation. Indeed, while it is easy to focus on the policy repercussions of a newly constrained Congress and newly hamstrung administrative state, this Article argues that equally important is the novel precedent that is set in this particular formulation of a clear statement rule, which stands almost …

What Mediation Romantics Can Learn From The Model T (Or Maybe The Chevrolet Trax), Nancy A. Welsh Jan 2024

What Mediation Romantics Can Learn From The Model T (Or Maybe The Chevrolet Trax), Nancy A. Welsh

Faculty Scholarship

When mediation was reintroduced to the U.S. in the 1970s, it was infused with a democracy-and-self-determination-enhancing, social justice ethos. As the process has been very successfully institutionalized, however, these ambitions have been scaled backalthough, at least arguably, certain "mediative elements" have actually been adopted (or coopted) by other procedural innovations. Perhaps it is time for those of us frustrated with the evolution of mediation to reconcile ourselves to the reality and value of a "basic" model of mediation designed for the sole purpose of getting parties from dispute to settlement-in much the same way that the basic model of a …

Narrow But Deep: The Mcculloch Principle, Collective-Action Theory, And Section Three Enforcement, Neil S. Siegel Jan 2024

Narrow But Deep: The Mcculloch Principle, Collective-Action Theory, And Section Three Enforcement, Neil S. Siegel

Faculty Scholarship

In Trump v. Anderson, 144 S. Ct. 662 (2024), the Supreme Court of the United States held that the Colorado Supreme Court erred in excluding President Donald J. Trump from the Republican Party's primary ballot in the state.  The Court reasoned that the Constitution makes Congress, not the states, solely responsible for enforcing Section 3 of the Fourteenth Amendment.  Scholars of Section 3 have demonstrated that Section 3 is self-executing, so the Court's rationale lacks a sound basis in the original or contemporary meaning of the text of the Civil War Amendments, the original intent of their drafters, or …
