What challenges did Supreme Court of Justice of the Nation face before AI implementation?

Millions of legal records existed only in paper or fragmented digital formats, making retrieval slow and inaccessible to the public. Existing infrastructure could not handle high-performance processing of unstructured legal documents. There was increasing public demand for open access to judicial decisions and historical data. Specialized technology was needed for processing legal language and context in Spanish. Interoperability between legacy systems and modern cloud infrastructure was required.

What was the impact of the AI solution?

Reduced legal information retrieval time from days to minutes for public users and legal professionals. Enabled transparent access to more than 93,000 judgments and 304,000 theses online. Over 600,000 visits to the legal search engine demonstrate massive adoption and public interest. Established a first-ever Spanish judicial language model, transferable to other Latin legal systems. Modernized the Mexican judicial system with pillars of open justice: transparency, innovation, collaboration, and accountability.

Supreme Court of Mexico transforms public legal access with AI-powered search engine

Use case typeLegal document automationUpdated Jun 13, 2026

The Supreme Court of Justice of the Nation (SCJN), Mexico’s highest constitutional authority, undertook a major digital transformation to make millions of legal records accessible to the public. SCJN collaborated with Microsoft and partner TEIA to digitize its archives and implement advanced natural language processing (NLP) models, leveraging Azure ML, Azure Databricks, Azure Data Lake Storage, and Azure Data Factory. The new system enables the classification, retrieval, and contextual presentation of legal documents and historical court records, making legal information available to all citizens, not just legal professionals. A secure hybrid cloud infrastructure integrated the court’s on-premises data center with Azure, allowing for continuous model training and efficient data management. A public-facing legal search engine was developed, capable of handling unstructured data in Spanish, offering access to over 93,000 judgments and 304,000 theses through a user-friendly web portal. Legal language models were custom-trained to recognize organizations, legal precepts, and international legal references, providing specialized legal search capabilities not previously available in Spanish. Migrating massive volumes of institutional data required building secure cloud data repositories and custom VPN connectivity between the court’s premises and the cloud environment. The outcome significantly accelerated access to information, improved the transparency and accountability of the judiciary, and set a new standard for digital innovation in Latin America’s legal sector.

Architecture

The Supreme Court (SCJN) integrated its on-premises data center with Azure using a secure VPN, moving massive archives into Azure Data Lake Storage with Azure Data Factory. Azure Databricks powered the training of specialized natural language models, with hybrid connectivity enabling continuous model optimization. The resulting architecture supported a public-facing, AI-powered legal search engine accessing structured and unstructured data, classified, and indexed in cloud storage.
