Just-War Audit Workbench for Policy Teams
A guided workflow that scores a proposed military action or sanctions package against the just-war rubric that mirrors Grotius's own three-book structure — lawful authority, just cause, lawful conduct — and outputs a citation-backed audit memo.
Concept
A single-purpose decision-support tool for the legal and policy teams who must argue whether a proposed use of force, reprisal, or sanctions package is defensible. The analyst describes the proposed action (actor, stated cause, target, means), and the tool walks a rubric that mirrors the treatise's own three-book architecture: Book I — who may lawfully wage war and when war is lawful at all; Book II — which causes (defense, recovery of what is one's own, punishment) can justify force; Book III — what remains forbidden even against an enemy (mistreatment of prisoners, bad faith, immoderate destruction). At each step the tool surfaces the governing classical proposition with its citation, asks the analyst to attach supporting evidence, and flags unmet or unevidenced criteria. The output is a one-page audit memo with a criteria scorecard and full citations, ready for internal review or publication. The wedge is deliberately narrow: the tool structures and documents the argument; it does not predict outcomes or render verdicts.
Why now
The new paper [0] puts the complete three-book text of De jure belli ac pacis in hand as the working source. Its own organization — rights and lawful authority (Book I), justifying causes (Book II), permissible conduct in war (Book III) — is effectively a pre-built audit rubric that maps one-to-one onto the jus ad bellum / jus in bello split that legal teams still use, so the checklist does not have to be invented, only operationalized. The abstract's editorial context (a chair for German legal history and civil law at Universität Hamburg) indicates the text circulates in critically edited, citable form, so proposition-level citations can be made stable. Today this analysis is assembled ad hoc in word processors; the demonstrated readiness is a structured text whose architecture already matches the deliverable.

AI assessment
A niche, high-utility documentation tool that operationalizes a classical legal framework into a structured audit workflow for defense legal teams.
- Evidence strength 4/5
- The idea directly maps the three-book structure of the cited text to a functional workflow, leveraging the existing architecture of the research source.
- Market pull 3/5
- While the target users (MoD, ICRC) have high urgency for compliance, the actual buyer pool for a specialized Grotius-based tool is very small.
- Novelty & moat 3/5
- It evolves the 'Grotius Citator' from a passive lookup tool into an active workflow tool, providing a distinct value proposition of audit generation.
- Feasibility 5/5
- The product is essentially a structured digital form and template generator based on a static text, requiring minimal technical complexity to build.
- Wedge clarity 5/5
- The wedge is exceptionally sharp: it focuses solely on structuring and documenting the argument rather than attempting to automate legal judgment.
- Simplicity / focus 5/5
- The product is a single-purpose workbench with a clear input-process-output loop, avoiding any platform bloat.

Who benefits
- International Committee of the Red Cross (ICRC)organization
Its legal division routinely argues positions on the law of armed conflict; a citation-backed criteria scorecard gives its lawyers a repeatable structure for reviewing proposed operations and public positions.
Its International Law programme publishes assessments of the legality of uses of force; the workbench standardizes the criteria trail behind such publications.
Military lawyers must document the legal review of operations; a scorecard with attached evidence creates the audit trail they are required to keep.
- Public International Law & Policy Group (PILPG)organization
This pro bono counsel serves states and parties in conflict with small teams; a low-cost argumentation scaffold multiplies what each lawyer can produce.
The centre teaches and researches the classics of international law and would use the rubric in both training and applied projects.
