Datafication, Power, And Publics In India's National Digital Health Ecosystem, Ramya Chandrasekhar

Socio-Legal Review

While evident for a long time, the COVID-19 pandemic starkly illustrated the need to strengthen India’s public healthcare system. But since 2017, the solution to India’s public health woes takes the shape of the National Digital Health Ecosystem (‘NDHE’) – a digital system for the generation, use, and “frictionless” circulation of health data across healthcare actors through the use of artefacts such as health IDs, electronic health records, data standards, and federated computing architectures. These artefacts are not neutral technological systems. Rather, together with social practices, they constitute a “data infrastructure.” Seeing the NDHE as a data infrastructure allows us …

Locating Socio-Legal Research In Pakistan: A Reflexive Approach, Maryam S Khan

Socio-Legal Review

This article presents a detailed survey of the sites of emergence and development of socio-legal research in Pakistan, locating it on a historical arc extending from the decolonisation era to contemporary times, and organically tracing its trajectory through contextual shifts in knowledge production more broadly. As such, the article takes a reflexive approach to identifying and classifying the socio-legal that eschews pre-existing benchmarks of what constitutes the field globally. In so doing, it makes the central argument that the meaning and evolution of “socio” in socio-legal is contingent on social and historical context. The article begins with a broad Pakistan-India …

Socio-Legal Enquiry On A Global Scale: Legal Intermediation, The Geography Of Extraction, And The (Re)Negotiation Of Africa’S Relationship With The World Economy, Sara Dezalay

Socio-Legal Review

This paper asks: what does socio-legal enquiry tell us about one of the most pressing problems of our time— climate change? Can (and should) socio-legal enquiry provide a meaningful critique of the so-called green transition? Law’s ubiquity in the ongoing phase of capitalism—from the predominance of private contracts in the regulation of relations between states and transnational corporations to the formidable growth of transnational dispute settlement mechanisms since the turn of the 1990s raises a challenge for socio-legal enquiry. Where do we put the cursor of law’s empowering potential as opposed to its enabling role in reproducing patterns of inequality …

Measuring The Impacts Of Experiential Legal Education, Robert R. Kuehn, Peter A. Joy

Scholarship@WashULaw

Experiential legal education has become an essential component of the law school curriculum, emphasizing "learning by doing" through practical experiences in law clinics, externships, and simulation courses. This pedagogical approach offers law students the critical skills and professional values required for effective and ethical practice. Despite its recognized importance and parallels with other professional disciplines, legal education still requires minimal experiential education compared to other professions. This reluctance likely stems from lingering skepticism by some legal educators about its value, even though many stakeholders, including other educators, students, recent graduates, and other legal professionals, acknowledge its significance.
