Environmental litigation stemming from human-made disasters associated with large-scale infrastructure investments is commonly initiated by concerned stakeholders seeking environmental justice. The investigative process involves Post-Event Environmental Impact Assessments (PEEIA), which entail retrospective analyses heavily reliant on expert judgment to establish the causal nexus between the evidence of environmental damage and the alleged tortious conduct. A key concern within PEEIA pertains to effectively screening expert judgment when the scientific basis is in dispute, given that critical determinants in tort litigation revolve around the reliability and relevance of expert judgment. However, these assessments contend with complex ecosystems, along with discrepancies in the scientific knowledge supporting claims of the tortfeasor's liability. Consequently, the principal challenge of PEEIA lies in effectively navigating the inherent uncertainty surrounding expert judgment.

应对人为灾害诉讼事后环境影响评估中专家判断的不确定性

与大规模基础设施投资相关的人为灾难引发的环境诉讼通常是由寻求环境正义的相关利益相关者发起的。调查过程涉及事后环境影响评估（PEEIA），需要进行严重依赖专家判断的回顾性分析，以确定环境损害证据与涉嫌侵权行为之间的因果关系。鉴于侵权诉讼中的关键决定因素围绕专家判断的可靠性和相关性，PEEIA 的一个主要关注点是在科学依据存在争议时有效筛选专家判断。然而，这些评估涉及复杂的生态系统，并且支持侵权人责任主张的科学知识存在差异。因此，PEEIA 的主要挑战在于有效应对专家判断固有的不确定性。
