Court of Justice of the European Union
Transforming how 3,000+ employees across Europe's highest court research, translate, and process legal documents with AI.
The Challenge
The Court of Justice of the European Union, with over 3,000 employees across multiple departments, faced critical operational inefficiencies that threatened their ability to deliver timely justice.
Legal research was painfully manual, translation across 24 EU languages took weeks, and departments operated in silos — duplicating efforts and lacking standardized automation.
- Case law research took 16 hours per complex case
- Translation turnaround stretched to weeks across 24 languages
- 90% of metadata extraction was handled manually
- Citation verification consumed 8 hours per document
- Departments operated in silos, duplicating effort
The Journey
How NatusAI OS transformed operations
Natus Analyzer
How we analyzed
Audited workflows across all departments: legal research processes, translation pipelines, metadata handling, citation tracking, document summarization, and transcription workflows.
Mapped information flows and system interdependencies across the entire institution to identify bottlenecks and redundancies.
What we discovered
- Lawyers spent days sifting through thousands of precedents manually
- Translation costs consumed a significant portion of the operational budget with weeks-long turnaround times
- Manual metadata extraction was error-prone and consumed hundreds of staff hours weekly
- Citation and reference linking required dedicated teams working full-time
- No centralized Q&A system meant staff repeatedly searched for the same information
Natus Transformer
How we transformed
Designed a comprehensive multi-assistant AI ecosystem tailored to CJEU's specialized legal workflows.
Built on GPT-4 and Claude 3.5 Sonnet with custom fine-tuning, integrated with existing document management systems and legal databases.
Developed automated NLP pipelines for reference extraction, citation linking, and cross-document relationship mapping across 24 EU languages.
The transformation
- Specialized AI assistants outperformed general-purpose tools for legal domain tasks
- Smart routing logic matching user queries to optimal specialized assistants dramatically improved accuracy
- Departmental knowledge collections enabled teams to curate and query their own specialized repositories
Natus Builder
What we built
Deployed 12+ domain-specific AI assistants covering legal research, multi-language translation, metadata extraction, citation linking, document summarization, workflow automation, Q&A systems, knowledge management, hearing transcription, text correction, and department-specific tools.
