Divine Detachment: Beachy V. Assemblies Of God And A New Interpretation Of The Ecclesiastical Abstention Doctrine, Juarez Mcleod Johnson

MC Law Review

In the landmark case of Beachy v. Mississippi District Council for Assemblies of God, the Mississippi Supreme Court redefined its interpretation of the ecclesiastical abstention doctrine—marking a pivotal shift in church-state jurisprudence. Traditionally, this doctrine instructed courts to defer to the highest internal authority of a church when deciding disputes within hierarchical religious organizations. However, the court’s decision in Beachy significantly departed from this principle by designating the local pastor and congregation as the supreme authority over local church affairs, even within a hierarchical structure.

This Casenote explores the profound implications of the Supreme Court’s ruling, focusing on its …

Auer Deference: He Who Writes The Law Must Not Adjudge Its Violation, William G. Kennedy

MC Law Review

This Comment explores Auer deference and its application to the Sentencing Guidelines, the Sentencing Commission, and its commentary. Auer deference, in its simplest form, requires courts to give controlling weight to an agency’s interpretation of its own regulations unless it is plainly erroneous or inconsistent with the regulation. Following the Court’s decision in Kisor—expressly limiting Auer’s application, the circuit courts have disagreed on the applicability of Auer to the Sentencing Commission’s commentary regarding career offender designation. This disagreement begs for an appearance before the Court of Last Resort, but until that day, the courts must rigidly apply Kisor to …

The thesis evaluates the doctrine of unconscionability as a critical safeguard against unfair contractual provisions, highlighting how procedural and substantive inequalities often …

Dynamic Wellbore-Integrity Framework For Post-Blowout Capping Of Offshore Wells, Abdelhakim Khouissat

Theses and Dissertations

In the aftermath of a blowout, a well undergoes a period of unrestricted fluid discharge (de facto primary recovery) followed by pressure buildup after its shut-in, which can adversely impact wellbore integrity. The quintessential example is Union Oil’s 1969 “A-21” well blowout in California’s Santa Barbara Channel, where seafloor-broaching incidents (oil “boilups”) kept taking place from the sides of the well following several failed well-capping attempts, until reservoir depletion eventually allowed a successful shut-in.Analytical and numerical reservoir depletion models are coupled with near-wellbore geomechanics to quantify yardsticks related to the post-blowout discharge utilized to indicate dangers for underground blowouts, in …
