Algorithmic Transparency in the Judiciary

The Right to Algorithmic Explanation

When an AI system influences a decision affecting you, you have the right to understand how it reached that conclusion. In the judicial sphere, this is especially critical.

Regulatory Framework

• GDPR art. 22: right not to be subject to automated decisions with legal effects
• EU AI Act: transparency obligation for high-risk systems
• Art. 24 CE: effective judicial protection (includes right to know the grounds)
• LOPJ art. 248.3: judgments must contain the legal grounds

Transparency Levels

1. Usage transparency: informing that AI is used (minimum requirement)
2. Process transparency: explaining what data it uses and how it processes it
3. Result transparency: justifying why it reached a specific conclusion
4. Model transparency: access to code and training data (maximum)

AI Usage Logs (audit logs)

Every judicial AI system must maintain:

• What tool was used and when
• What query was made
• What result it returned
• What decision the judge ultimately made
• Whether the decision matched or differed from the AI output

Challenge Mechanisms

Parties can challenge AI use if:

• They were not informed of its use
• The system is not audited or certified
• There are indications of bias
• The motivation depends excessively on algorithmic output
• There is no possibility of contradiction regarding input data
