From Authorization To Loss: A Blockchain Forensic Analysis Of Transaction-Level Mechanisms In Cryptocurrency Airdrop Scams, Chanwoo Shin, Kyung-Shick Choi

International Journal of Cybersecurity Intelligence & Cybercrime

Cryptocurrency airdrop scams have emerged as a rapidly growing form of cyber-enabled financial crime, yet remain underexplored in empirical research. This study examines how transaction-level mechanisms and offender strategies influence variation in monetary loss in airdrop scam incidents. Grounded in Cyber-Routine Activities Theory (Cyber-RAT), the study conceptualizes financial harm as occurring within decentralized environments where users’ online behaviors, particularly transaction authorization, intersect with limited digital capable guardianship. Data were drawn from 112 validated airdrop scam cases reported on Chainabuse.com between January and December 2025. Blockchain forensic analysis using Breadcrumbs was conducted to reconstruct transaction pathways, identify exchange interactions, and detect …

Privatising International (Organizations) Law, Melissa (M.J.) Durkee

Scholarship@WashULaw

This essay explores the increasing role of private commercial actors within international organizations (IOs) and the implications for international law. Once conceived as state-centred institutions, IOs now routinely involve corporations, trade associations, and philanthropic foundations in lawmaking, policy-setting, financing, and implementation. These actors participate through multiple channels: as observers, delegates, stakeholders, funders, and partners. While private involvement has historical precedents, its contemporary scale and formalization mark a significant transformation in global governance. International law, however, offers little guidance on the boundary between public and private authority, leaving legitimacy concerns unresolved. To evaluate privatization, the article identifies two competing logics: a …

Justifying The Fourth Amendment, Daniel Epps

Scholarship@WashULaw

Why does the Fourth Amendment belong in the Constitution? This question is not whether society should impose some legal restraints on government searches and seizures. Rather, why should such protections reside in our national charter, superior to other forms of law and insulated from change via ordinary majoritarian political processes? Despite major disputes about the Fourth Amendment’s content, Fourth Amendment theorists rarely ask this question. Almost all agree that the Fourth Amendment’s constitutional protections are critically important—even if no one can agree exactly what those protections are.

This Article seeks a justification for the Fourth Amendment—the reason why search-and-seizure protections …

Seeing International Organizations In A Shifting Landscape: Law, Practice, And Authority, Melissa (M.J.) Durkee

Scholarship@WashULaw

This book review symposium comes at a moment of visible strain in the postwar legal order. As of this writing, Canadian Prime Minister Mark Carney has described a "rupture" in the rules-based world order, warning that multilateral institutions and the architecture of collective problem-solving are under threat. Notably, Carney issued that warning at the World Economic Forum in Davos, before an audience of "companies and countries." The setting underscores a broader shift in global governance, in which states, firms, and philanthropic actors increasingly occupy shared institutional spaces, unsettling assumptions about law and power at the international level. The books under …

Sustainability Assurance, Andrew F. Tuch, Luca Enriques, Alessandro Romano

Scholarship@WashULaw

A robust literature examines sustainability disclosures by public corporations, but legal scholarship has largely overlooked the role of third-party assurance—or verification—of such disclosures. This is a notable omission given the extensive literature on the auditing of financial statements, a related form of assurance.

This article responds by examining the role of assurance in sustainability reporting. In keeping with the theme of this symposium volume, it draws on US and EU law. Our discussion begins in Part I with sustainability disclosures, focusing on the requirements and practices of public companies. In Part II, we introduce sustainability assurance as well as assurance …

Tariffs And The Taxing Power: Historical Lessons For Major Questions And Nondelegation, Conor Clarke, Ari Glogower

Scholarship@WashULaw

American law is grappling with basic questions about the President’s power to impose tariffs—questions concerning whether Congress can delegate this authority, and the degree to which it has. But the ongoing tariff controversy emerges against a backdrop of conflicting and shifting historical practice. Early Congresses drafted tariff statutes in painstaking detail, while some of the broadest delegations in the early Republic involved internal taxes. In the modern era, by contrast, Congress has delegated more expansive tariff powers to the President, while retaining closer control over internal taxes. How should we understand this seemingly conflicting history of practice, and its relevance …

Foreword: The Constitution And Public Finance—Why Now And Why Ever?, Conor Clarke, Eric Kubo

Scholarship@WashULaw

This paper introduces the Washington University Law Review’s 2026 symposium issue on “Taxing, Spending, and the Constitution.” We situate the symposium’s ten papers within three interconnected developments in public finance law: the Supreme Court’s recent decision on the Sixteenth Amendment in Moore v. United States; the Trump Administration’s assertions of executive control over appropriated funds; and the use of emergency and trade statutes to justify sweeping tariff authority.

We also step back to ask why constitutional issues in public finance—long treated as a technical backwater—have become such a central site of doctrinal and political conflict. We offer several explanations beyond …

Tariffs And The Progressive Fiscal Constitution, Lawrence J. Liu, Alex Zhang

Scholarship@WashULaw

For more than a century, progressive taxation has constituted the American fiscal state. A resurgent and expanding tariff regime, however, threatens that commitment to progressive distribution. Given the ongoing popularity of tariffs, this Article examines how they might be designed and administered in a way that mitigates their regressive distributive impact. The Article thus develops and assesses proposals to (1) vary tariff burdens in accordance with the consumption of imported goods, (2) reduce income- or payroll-tax burdens on lower-income households, and (3) earmark tariff revenue for specified spending programs. Although none is perfect, we seek to articulate possibilities and highlight …

Data Rights For Workers, Pauline Kim, Rachel Leavitt

Scholarship@WashULaw

Workers are subject to immense amounts of data collection on the job, and the algorithmic management tools built with that data can produce negative effects, including deskilling jobs, unstable work hours, reduced wages, and dangerous and degrading working conditions. Workers thus have significant interests how their data are collected and used, and yet they have been excluded from nearly all the recently enacted or proposed data protection laws. Their exclusion stems from data protection’s roots in privacy law and theory, which primarily focused on consumers as data subjects. Current data protection laws, even if expanded to cover workers, would provide …

Apportioned Direct Taxes, Conor Clarke, Ari Glogower

Scholarship@WashULaw

The Constitution requires that Congress apportion any “direct” tax among the states by population. This once-dormant provision is now the most important constitutional limitation on Congress’s taxing power. Last year, in Moore v. United States, the Supreme Court seriously considered, for the first time in decades, whether to invalidate an Act of Congress as an unapportioned direct tax. While the law survived, Moore has opened a new era in which scholars and policymakers must again take apportionment seriously. Yet the apportionment requirement remains poorly understood.

This Article provides a new perspective on apportionment by examining how Congress and Treasury …

Space Enterprises As International Lawmakers: Nudges, Pledges, And Other Bottom-Up Modalities, Melissa (M.J.) Durkee

Scholarship@WashULaw

Private entities are influencing the development of international space law. Space enterprises need regulatory certainty and consistent standards to attract capital and develop their plans for space. Yet, states have lagged in their capacity to make multilateral international space law in traditional public fora. Private entities have responded to this legal lag by attempting to create, develop, and nudge international space law in commerce-friendly ways. This chapter surveys a variety of modalities by which commercial actors can affect the development of international law, offers several examples of how commercial lawmaking efforts

How International Organizations Regulate Lobbyist Access, Melissa (M.J.) Durkee

Scholarship@WashULaw

This chapter explores how international organizations (IOs) regulate lobbyist access through participation frameworks rather than traditional lobbying laws. While no unified international lobbying regime exists, IOs use rules on NGO 'consultation' and 'engagement' to structure access. These rules, rooted in historical practices like the UN's Economic and Social Council (ECOSOC) accreditation system, prioritize representativeness and legitimacy over transparency and accountability. As lobbying increasingly targets international forums, concerns about undue influence (the 'lobbying critique') and insufficient stakeholder inclusion (the 'access critique') have driven divergent reforms: some IOs, like the World Health Organization, have adopted stricter controls; others, such as the GAVI …

Taking Legality Seriously: What The Major Questions Doctrine Is — And Isn't, Andrea Scoseria Katz, Ofra Bloch

Scholarship@WashULaw

The Major Questions Doctrine (MQD), a controversial recent innovation of the Roberts Court that applies stricter scrutiny to “major” actions taken by federal agencies, has faced criticism for being atextual, unprincipled, and nakedly ideological. But this critique misses the fact that the doctrine has near-exact analogues in many other legal systems, where it is an established tool for reining in executive overreach. This Article argues that, while the MQD reflects valid rule-of-law concerns, as applied, it lacks theoretical clarity, consistency and limits. More importantly, the Court itself lacks a theory of what the MQD is. We provide an answer grounded …

Bridging The Gap: Predictors Of Alignment Of Parent And Caseworker Perceptions Of Engagement, Jianchao Lai, Michelle I. Graef

Center on Children, Families, and the Law: Faculty Publications

This study examined predictors of alignment between parents’ and caseworkers’ perceptions of family engagement in child welfare services. Using data from 2,274 Alternative Response (AR)–eligible families randomized to AR or Traditional Response, engagement was assessed across the domains of Receptivity, Buy-in, Worker-family Relationship, and Mistrust using a modified Yatchmenoff (2005) scale. Multinomial logistic regression models identified factors associated with agreement and discrepancy between ratings of family engagement within the parent and worker dyad. While both parents and workers valued engagement, workers were more likely to provide higher overall engagement ratings, although the direction of discrepancy varied across specific subscales. Greater …

Institutional Constraints On Investigative Oversight: Accountability And Governance Of The Investigation Supervision Bureau (Biro Pengawas Penyidikan) Of The Indonesian National Police, Mastalina Sinaga, Dhiajeng Prativi

Jurnal Kriminologi Indonesia

Investigative professionalism constitutes a fundamental pillar of the criminal justice system; however, its realization is frequently constrained by institutional design and procedural limitations within oversight mechanisms. This article examines the role of the Investigation Supervision Bureau (Biro Pengawas Penyidikan (Birowassidik)) of the Criminal Investigation Agency (Badan Reserse Kriminal (Bareskrim)) of the Indonesian National Police (Polri) in handling public complaints related to investigative performance. Rather than presuming the existence of a unified ‘Code of Silence’, this study adopts a qualitative critical analysis to assess the structural and procedural constraints inherent in Birowassidik’s mandate as a complaint-based supervisory institution. The analysis demonstrates …

Analyzing Modern Scam Typologies: From Pig-Butchering And Nigerian Advance-Fee Fraud To Crypto Airdrop Schemes, Katalin Parti, Sinyong Choi, Thomas Dearden

International Journal of Cybersecurity Intelligence & Cybercrime

Rapid advancements in digital infrastructure and decentralized networks have fundamentally altered the nature of contemporary cybercrime, making comprehensive empirical and technical analysis more crucial than ever. To address these challenges, this editorial summarizes the research contributions featured in this issue of the International Jour nal of Cybersecurity Intelligence and Cybercrime. The included papers examine the structural on-chain dynamics of sanctioned pig-butchering operations, the representational production and AI-driven evolution of the “Nigerian scam” label, the critical transaction-authorization factors driving losses in crypto airdrop schemes, and the optimization of sentence-transformer models for automated Host Intrusion Detection System (HIDS) alert enrichment. Together, these …

Three-Tier On-Chain Transaction Architecture In A Sanctions-Linked Pig-Butchering Network: A Blockchain-Forensics Case Study, Matthew Stern, Kyung-Shick Choi

International Journal of Cybersecurity Intelligence & Cybercrime

n October 2025, the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) sanctioned 29 Bitcoin addresses asso ciated with the Prince Group and Chen Zhi, providing an opportunity to examine the internal on-chain structure of a sanctions-linked pig-butchering network. This blockchain-forensics case study analyzes the group of 29 addresses using blockchain tracing, cross-plat form attribution checks across multiple commercial analytics platforms, exposure screening, and thematic analysis of transaction be havior. Because the case rests on OFAC designations and DOJ allegations, the traced flows are interpreted as patterns consistent with suspected laundering rather than adjudicated crimes; no fiat …
