Still Making It Up As He Goes: Revisiting The Hyper-Rhetorical Presidency In Trump’S Second Term, Richard Holtzman

Politics, Law, and Society Faculty Journal Articles

In Fast Capitalism’s 2020 issue, “This is Not Normal,” I explored Trump’s propensity for improvised rhetoric during his first term; that is, his reliance on “making it up as he goes” in his public statements, whether communicated verbally or through social media. The primary goal of my original essay was not simply to identify the president’s ad-hoc communication style—which is clear for all to see—but to argue that the president’s tendency toward improvisational speech matters because it represents more than just his approach to communication. This tendency toward improvisation also constitutes much of his approach to governing.

In “Making It …

Cultural Coordinates Of Credibility And Sticky Scripts: Womaning Versus Lawyering In The Indian Legal System, Bhumika Billa

Socio-Legal Review

Based on a multimodal and empirical analysis, the article presents Indian women (identifying) lawyers’ lived experiences of epistemic injustice at the sites of legal work in Delhi. The analysis brings a painting, a short film, and 15 semi-structured interviews in conversation with each other to understand women lawyers’ shared experiences of being perceived as “less credible,” and the strategies they have been adopting to assert credibility. The theoretical contribution can be captured by three key arguments. First, using Arpita Singh’s painting, ‘My Lollipop City: Gemini Rising, 2005,’ I argue that the Indian legal system has a “sense of” Delhi. …

Algorithmic Governance And Nondiscrimination Rights In The Workplace, Pauline Kim

Scholarship@WashULaw

This chapter analyzes existing legal responses to the problem of discriminatory algorithms in the workplace. As firms increasingly rely on algorithms or automated decision systems, a type of artificial intelligence, to manage their workforces, concerns have grown that these tools can systematically exclude historically disadvantaged groups. One response is to rely on traditional anti-discrimination law. These laws clearly prohibit certain forms of algorithmic discrimination; however, the complex, opaque nature of algorithms makes identifying and proving discriminatory harms challenging. Another response looks to broader frameworks of data protection and algorithmic regulation to protect against workplace discrimination. These initiatives are promising, but …

Abolish What?, Benjamin Levin

Scholarship@WashULaw

From leading academic journals to popular press outlets, abolitionist activism and scholarship have earned airtime in national debates about criminal justice reform. But what is "abolition?" When scholars, lawyers, and activists talk about abolition, they seem to mean very different, even conflicting, things. In this Essay, I focus on a core question that might divide different abolitionists-and different critics of abolition: what is to be abolished? Abolitionists argue that it's critically important to abolish something, while critics of abolition insist that something is necessary to a well-functioning society. Yet, it's not always clear what that something is-both for abolitionists and …
