Child Custody Outcomes In Cases Involving Parental Alienation And Abuse Allegations, Joan S. Meier, Sean Dickson, Chris O'Sullivan, Leora Rosen, Jeffrey Hayes Jan 2019

Child Custody Outcomes In Cases Involving Parental Alienation And Abuse Allegations, Joan S. Meier, Sean Dickson, Chris O'Sullivan, Leora Rosen, Jeffrey Hayes

GW Law Faculty Publications & Other Works

Arguably the most troubling aspect of justice system response to intimate partner violence is custody courts' failure to protect children when mothers allege the father is abusive. Family courts' errors in assessing adult and child abuse, and punitive responses to abuse allegations, have been widely documented.

A significant contributor to these errors is the pseudo-scientific theory of parental alienation (PA). Originally termed parental alienation syndrome (PAS), the theory suggests that when mothers allege that a child is not safe with the father, they are doing so illegitimately, to alienate the child from the father. PA labeling often results in dismissal …

U.S. Government To Award Billions Of Dollars In Contracts To Open Electronic Marketplaces To Government Customers—Though Serious Questions Remain, Christopher R. Yukins

GW Law Faculty Publications & Other Works

Proposals to the U.S. General Services Administration are due soon in a $6 billion procurement under which multiple no-cost contracts will be awarded to vendors that will open electronic marketplaces to federal users making micro-purchases (generally up to $10,000). Although federal purchase card holders have long been able to make micro-purchases with few regulatory constraints regarding competition, transparency or socioeconomic requirements, this new initiative appears likely to normalize and expand those purchases—and so may revolutionize small purchases in the federal market. This article assesses some of the key concerns -- from cybersecurity to bid protests to pricing -- that still …


The International Law Origins Of American Federalism, Anthony J. Bellia Jr., Bradford R. Clark Jan 2019

The International Law Origins Of American Federalism, Anthony J. Bellia Jr., Bradford R. Clark

GW Law Faculty Publications & Other Works

Courts and commentators have long struggled to reconcile robust federalism doctrines with the text of the Constitution. These doctrines include state sovereign immunity, the anti-commandeering doctrine, and the equal sovereignty of the States. Supporters of such doctrines have generally emphasized the history, structure, and purpose of the Constitution over its precise text. Critics of such doctrines have charged that they lack adequate support in the Constitution and are the product of improper judicial activism. This Article reconciles federalism and textualism by looking to a surprising source—international law. The Constitution contains numerous references to “States”—a term of art drawn from the …

The Forgotten Fisa Court: Exploring The Inactivity Of The Atrc, Aram Gavoor, Timothy M. Belsan

GW Law Faculty Publications & Other Works

The Alien Terrorist Removal Court (ATRC) was established in 1996 after immense political pressure from the Reagan, Bush, and Clinton Administrations and wide bipartisan support to serve as a forum to prosecute the most complex and difficult national security immigration removal cases while protecting vital classified information from public disclosure. Yet, after twenty-three years, this Article III court has not heard a single case.

This Article provides a fresh and critical inquiry into this veritable zombie court that has fallen from the public consciousness, yet still exists with a standing cadre of designated judges. It fills a significant gap in …

Moreover, there long has been a vast divide between the approaches of the U.S. and European Union (EU) to regulating privacy – a divide …


From Dodge To Ebay: The Elusive Corporate Purpose, Dalia Tsuk Mitchell Jan 2019

From Dodge To Ebay: The Elusive Corporate Purpose, Dalia Tsuk Mitchell

GW Law Faculty Publications & Other Works

This article examines the history of the law of corporate purpose. I argue that the seemingly conflicting visions of corporate social responsibility and shareholder wealth maximization, which characterize contemporary debates about the subject, are grounded in two different paradigms for corporate law — a socio-political paradigm and an economic-financial one. Advocates of the socio-political paradigm have historically focused on the power that corporations could exercise in society, while those embracing the economic-financial paradigm expressed concerns about the power that the control group could exercise over the corporation’s shareholders. Over the course of the twentieth century, scholars have debated the merits …

The Lost History Of The Ilo’S Trade Sanctions, Steve Charnovitz Jan 2019

The Lost History Of The Ilo’S Trade Sanctions, Steve Charnovitz

GW Law Faculty Publications & Other Works

This essay about the International Labour Organization (ILO) presents the lost history of the ILO's trade sanctions. Although the ILO nowadays is characterized as a toothless international organization, in fact, as the one of the earliest specialized international agencies, the ILO was endowed in 1919 with a system for enforcement that included the possibility of trade sanctions against countries failing to comply with ratified ILO conventions. Even though the original provisions for ILO sanctions were always in plain view in the Treaty of Versailles, the literature on the ILO over the past few decades has largely overlooked the existence of …
