“Embodied AI” and the Direct Participation in Hostilities: A Legal Analysis
“EMBODIED AI” AND THE DIRECT PARTICIPATION IN HOSTILITIES: A LEGAL ANALYSIS
This legal analysis questions whether the International Humanitarian Law (IHL) concept of a civilian should be limited to humans, focusing on the utilization of embodied artificial intelligence (EAI) in armed conflict. The authors challenge the International Committee of the Red Cross's (ICRC) interpretive guidance on Direct Participation in Hostilities (DPH), arguing that it creates an imbalance that affords greater protection to civilian objects than to human combatants. By proposing a Turing-like test for DPH assessments, the article explores how increasingly advanced civilian EAIs might blur the distinction between civilians and civilian property during warfare.
Summary and content fields are drawn from the document text and are pending editorial review.
Who issued it
Who it governs
This article is for international lawyers, academics, and researchers studying the intersection of international humanitarian law, the law of armed conflict, and artificial intelligence.
What the document contains
The article examines how the legal concept of direct participation in hostilities (DPH) under International Humanitarian Law applies or fails to apply to embodied artificial intelligence (EAI). It contrasts narrow interpretations of DPH provided by the ICRC with wider alternative interpretations proposed by legal scholars, evaluating them through simulated near-, mid-, and long-term technological scenarios.
The text does not provide binding legal rules, legislative enactments, or official state military manuals, but rather offers an academic legal critique and analysis of existing international humanitarian law frameworks.
- The concept of a civilian under International Humanitarian Law (IHL) needs re-evaluation to account for future embodied artificial intelligence (EAI).
- The ICRC's interpretive guidance on Direct Participation in Hostilities (DPH) relies on a narrow interpretation that creates an unacceptable imbalance in favor of humanitarian considerations over military necessity.
- A Turing-like 'but-for test' can be integrated into DPH assessments to evaluate whether non-linguistic EAI behavior is functionally indistinguishable from human participation.
- Without adapting IHL, increasingly advanced civilian EAIs could inadvertently receive greater protection under the law than human combatants.
- Recognizing EAI participation in armed conflict raises complex secondary legal issues including private military contractors (PMCs), perfidy, and prisoner of war status.
