Multi-Agent Legal Verifier Systems for Data Transfer Planning
This addresses the need for scalable and interpretable automated compliance verification for organizations handling data under stringent privacy laws, representing a domain-specific incremental improvement.
The paper tackles the problem of legal compliance in AI-driven data transfer planning under strict privacy regulations like Japan's APPI, proposing a multi-agent legal verifier that achieves 72% accuracy, a 21 percentage point improvement over a single-agent baseline, with 90% accuracy on clear compliance cases and perfect detection of clear violations.
Legal compliance in AI-driven data transfer planning is becoming increasingly critical under stringent privacy regulations such as the Japanese Act on the Protection of Personal Information (APPI). We propose a multi-agent legal verifier that decomposes compliance checking into specialized agents for statutory interpretation, business context evaluation, and risk assessment, coordinated through a structured synthesis protocol. Evaluated on a stratified dataset of 200 Amended APPI Article 16 cases with clearly defined ground truth labels and multiple performance metrics, the system achieves 72% accuracy, which is 21 percentage points higher than a single-agent baseline, including 90% accuracy on clear compliance cases (vs. 16% for the baseline) while maintaining perfect detection of clear violations. While challenges remain in ambiguous scenarios, these results show that domain specialization and coordinated reasoning can meaningfully improve legal AI performance, providing a scalable and regulation-aware framework for trustworthy and interpretable automated compliance verification.
