TL;DR

This paper analyzes the legal and scientific challenges of a hypothetical court case seeking a preliminary injunction to halt CERN's LHC due to fears of Earth-destroying black hole creation. It proposes a judicial review framework using interdisciplinary tools to evaluate extreme scientific uncertainty, offering a structured approach for courts to meaningfully assess high-stakes, low-probability risks in complex scientific litigation.

ABSTRACT

What should a court do with a preliminary-injunction request to halt a multi-billion-dollar particle-physics experiment that plaintiffs claim could create a black hole that will devour the planet? The real-life case of CERN's LHC seems like a legal classic in the making. Unfortunately, however, no court has braved the extreme factual terrain to reach the merits. This article steps into the void. First, the relevant facts of the scientific debate and its human context are memorialized and made ripe for legal analysis. Next, the article explores the daunting challenges the case presents to equity, evidence, and law-and-economics analysis. Finally, a set of analytical tools are offered that provide a way out of the thicket - a method for providing meaningful judicial review even in cases, such as this one, where the scientific issues are almost unfathomably complex.

Motivation & Objective

• To address the legal and scientific paradox of a court reviewing a request to halt a billion-dollar particle physics experiment over a remote existential risk.
• To document the factual and human context of the CERN LHC debate, including scientific consensus and public fears about black hole creation.
• To identify the core challenges in applying equity, evidence law, and law-and-economics frameworks to cases involving extreme scientific uncertainty.
• To develop a practical, interdisciplinary method for judicial review in cases where scientific complexity overwhelms traditional legal analysis.
• To provide a precedent-setting analytical model for courts confronting novel, high-impact scientific risks with limited empirical data.

Proposed method

• Synthesizes scientific literature and public discourse on LHC black hole risks to establish factual grounding for legal analysis.
• Applies principles of equity and evidentiary standards to assess the balance of harms and the likelihood of irreparable damage.
• Integrates law-and-economics analysis to evaluate the cost-benefit trade-offs of halting the experiment versus allowing potential risk.
• Proposes a tiered judicial review framework that prioritizes scientific plausibility and expert credibility over absolute certainty.
• Uses interdisciplinary tools—drawing from philosophy of science, risk theory, and legal theory—to assess the legitimacy of judicial intervention.
• Develops criteria for determining when a claim, despite low probability, warrants judicial scrutiny due to catastrophic potential.

Experimental results

Research questions

• RQ1 How can a court meaningfully evaluate a preliminary injunction request when the alleged harm involves a scientifically remote but catastrophic risk?
• RQ2 What legal standards can be applied when the scientific evidence is contested and the risk assessment involves highly theoretical physics?
• RQ3 In what ways do traditional legal doctrines—equity, evidence, and cost-benefit analysis—fail or succeed in high-uncertainty scientific cases?
• RQ4 Can a judicial review process be designed to be both rigorous and accessible when the science is exceptionally complex?
• RQ5 What role should scientific consensus and expert credibility play in determining whether to grant an injunction in existential-risk cases?

Key findings

• The paper establishes that even low-probability, high-impact risks can justify judicial review if they meet criteria of scientific plausibility and potential irreversibility.
• Traditional legal doctrines such as the balancing of hardships and the likelihood of success are insufficient alone when applied to extreme scientific uncertainty.
• The proposed framework allows courts to assess claims without requiring scientific certainty, by focusing on the reasonableness of scientific claims and the credibility of experts.
• The analysis demonstrates that judicial intervention is not precluded by scientific complexity, provided that structured review mechanisms are in place.
• The framework enables courts to distinguish between speculative claims and those grounded in peer-reviewed scientific reasoning, even in cases involving theoretical physics.
• The study concludes that meaningful judicial review is possible in such cases through interdisciplinary integration of law, science, and risk theory.
