General State Attorney's Office modernises legal management with AI through Telefónica and IBM
25 February 2026 (Reading time: 4 min)
The General State Attorney's Office is moving forward in its digital transformation with TEMIS, an AI-powered application that locates and analyses previous lawsuits with speed and precision. Developed by Telefónica Tech in collaboration with IBM after the 2025 tender, TEMIS streamlines access to relevant legal information and supports faster, better-grounded decisions.
What TEMIS does
TEMIS organises a large volume of legal documentation and makes it searchable, contextual and actionable for state lawyers. It supports legal judgement, never replaces it, and keeps professional oversight at the centre.
- Finds related precedents and comparable cases.
- Surfaces similarities and differences that matter for argumentation.
- Reduces analysis time and improves consistency in criteria application.
- Frees capacity for higher-value legal work.
Built for how lawyers actually work
"When we started working on this project, we understood from the outset that AI would only be useful if it adapted to the way lawyers work, not the other way around. TEMIS achieves precisely that. It organises and makes accessible a huge volume of legal knowledge, allowing lawyers to devote their time to what really matters: analysing, deciding and providing judgement. That is true digital transformation," said Jacobo Garnacho, Head of Data&AI Sales at IBM.
Technology to structure and understand legal information
TEMIS runs on IBM cloud technology and uses IBM watsonx for intelligent organisation, classification and search across legal documents. Telefónica and IBM co-developed advanced natural language processing models and configured virtual agents so the platform can understand context and return relevant, explainable results.
The architecture is flexible and designed to scale progressively. It can absorb new document sets, handle growing volumes and adapt to different legal areas within the organisation as needs evolve.
Security, privacy and governance
TEMIS is configured to operate without processing personal data. It works with anonymised information or data stripped of identifiers, aligning with Public Administration requirements and protecting case files.
The project reflects a joint commitment by Telefónica and IBM to responsible, supervised and governed AI-prioritising traceability, transparency and control across the entire model lifecycle.
Impact for legal and management teams
These capabilities translate into faster analysis, more consistent application of criteria and more time for strategic legal work. "With TEMIS, we are taking a decisive step forward in our digital transformation strategy. This tool allows us to work with greater agility and precision, enhancing the quality of the legal assistance we provide to the State. Technology must be at the service of the public good, and this project shows that it is possible to incorporate artificial intelligence while maintaining the rigour, security and professional supervision that characterise the General State Attorney's Office," said David Vilas Álvarez, General State Attorney's Office.
"The development and integration of the TEMIS application into the General State Attorney's Office's existing systems brings innovation and legal support by allowing lawyers to offload repetitive tasks, reducing the time spent on analysing claims and other operational processes. The application of Generative AI in Public Administration is playing a key role due to its transformative power and its ability to automate many processes to make them more efficient and competitive," added Almudena Bonet, AI Product Manager at Telefónica Tech.
See it at Mobile World Congress
The project will be presented on Monday, 2 March, at 10:30 a.m., at the IBM stand at Mobile World Congress, in a conversation with David Vilas Álvarez (General State Attorney's Office), Almudena Bonet (Telefónica Tech) and Jacobo Garnacho (IBM). For more information: Telefónica at MWC 2026.
Practical takeaways for legal leaders
- Start with a high-impact use case-precedent search and case similarity deliver immediate productivity gains.
- Keep a human-in-the-loop and enforce decision transparency to maintain legal rigour.
- Apply strict data controls: anonymisation, access policies and audit trails from day one.
- Integrate with existing systems and workflows to reduce friction and speed adoption.
- Design for scale across practice areas, with clear metrics like time-to-response and consistency of criteria.
- Invest in training and change management so teams trust and use the system well.
