Virtual Vakil: A Multi-Agent Reinforcement Learning System for Comprehensive Legal Intelligence and Judicial Reform

Virtual Vakil presents a multi-agent reinforcement learning system designed for comprehensive legal intelligence in the Indian judicial context. The system employs 15 specialised AI agents, each trained for distinct legal functions — from case law research to courtroom argument simulation and document drafting.

Key Contributions

Research Highlights

1

First multi-agent RL system specifically designed for the Indian legal framework, incorporating IPC, CrPC, BNS, BNSS, and IT Act expertise.

2

15 specialised agents with role-specific reward functions — each optimised for a distinct legal task rather than general-purpose conversation.

3

Hierarchical coordination protocol enabling agents to collaborate on complex legal scenarios (e.g., Chanakya delegates research to Pustakalya, receives analysis from Nyaydhish).

4

Evaluation framework with domain-expert legal practitioners as annotators — not crowdsourced labels.

5

Deployment architecture optimised for WhatsApp delivery, enabling real-time legal assistance at scale.
