Spain’s Judiciary Lays Down the Law on AI: Human Judges Remain in Control

THE BOTTOM LINE

  • Increased Predictability: New guidelines create a uniform approach to AI use in courts across Spain, providing businesses and their legal counsel with a clearer understanding of the technological landscape in litigation.
  • Controlled Tech Adoption: Spanish judges are restricted to using only government-approved and judicially-vetted AI systems. This creates a “walled garden” for legal tech, impacting vendors and requiring lawyers to understand the specific tools in play.
  • No “Robot Judges”: The framework firmly establishes that AI is a support tool, not a decision-maker. Final judgments, evidence assessment, and legal interpretation remain exclusively in human hands, ensuring legal strategy must continue to focus on persuading a person, not an algorithm.

THE DETAILS

Spain’s General Council of the Judiciary (CGPJ), the governing body for the nation’s judges, has issued a landmark instruction on the use of artificial intelligence within the judicial system. This proactive move aims to create a “clear, homogeneous, and coherent framework” for judges and magistrates, aligning with both Spanish and broader EU regulations like the new AI Act. The primary goal is to harness the efficiency of AI while erecting strong safeguards to protect fundamental rights, prevent algorithmic bias, and uphold the integrity of judicial independence.

The cornerstone of the new rules is the principle of ‘effective human control’. The instruction makes it unequivocally clear that AI tools are to be used for assistance, not substitution. Judges and magistrates must maintain constant, conscious, and effective control over any AI system, which cannot operate autonomously to make judicial decisions, evaluate evidence, or interpret the law. This principle is reinforced by a strict prohibition against AI replacing human judges. Even when using an AI-generated draft of a ruling, the judge is required to perform a ‘complete and critical personal review’ and retains exclusive responsibility for the final text.

Practically, the instruction defines clear boundaries for what is permissible. Judges may use approved AI tools for tasks like legal research, reviewing case precedents, and preparing internal summaries or outlines. However, the use of AI is strictly forbidden for profiling individuals, predicting behavior, or handling specially protected personal data. Most critically for the legal tech market and corporate legal teams, judges may only use AI applications provided by the competent public administrations and explicitly vetted by the CGPJ. This ensures a controlled, secure, and standardized adoption of technology within the Spanish courts.
