A Spanish court opens the algorithm

Spain's Audiencia Nacional sanctioned an employer for concealing how its scheduling algorithm worked, and Brussels closed feedback on a materiality test that would reach the same tools.

Key takeaway

Spain's courts may settle AI dismissal law before the EU's own deadline reaches employers in 2027.

Spain's Audiencia Nacional, the national court that hears collective labour disputes, sanctioned an employer on 4 July for concealing how an algorithm that set shifts, days off and rest periods actually worked. Ruling 101/2026 concerns disclosure rather than dismissal, and legal analysis of it landed on 26 July⁠1. It establishes that workers may know the logic of the system organising their week.

Spanish labour lawyers now expect the first rulings on dismissals justified by AI performance scoring within weeks. The remedy they anticipate is the ordinary one for unfair dismissal: reinstatement, back pay and compensation. An employer stays liable even where an outside vendor built the tool, which closes off the obvious defence of pointing at the supplier.

Brussels arrived at the same question from the regulatory side. The European Commission's draft guidelines interpreting Annex III of the AI Act, the list of uses the Act treats as high-risk, covering recruitment, pay, evaluation, monitoring and termination, closed for stakeholder feedback on Thursday 23 July⁠2. They say a system counts as high-risk where its output "heavily influences" who advances or how a worker is evaluated, even when a human formally signs the decision. Few firms dismiss anyone by fully automated decision. Plenty score performance algorithmically and have a manager countersign. Brussels had already deferred these rules once.

Final guidelines are due at the end of 2026, ahead of a compliance deadline of 2 December 2027 that the Digital Omnibus pushed back from August this year. Germany's Bundesrat, the upper house of its parliament, approved the national enforcement law on 10 July, more than a year ahead of that deadline. A Madrid courtroom may reach a binding answer on AI dismissals before either date arrives.

Deep Analysis

In plain English

Two things happened around the same time. Spain's national court punished an employer for not explaining how a work-scheduling algorithm decided people's shifts. Separately, the European Commission stopped taking public feedback on its draft rules for AI systems used in hiring and management. The Spanish case is actually based on an older Spanish law from 2021, not the new EU rules, which are still being finalised and won't fully apply until December 2027. For now, national courts are deciding what companies must disclose about workplace algorithms faster than Brussels is.

Deep Analysis
Root Causes

Spain's ruling does not rest on the EU AI Act at all. It applies Article 64.4(d) of Spain's Workers' Statute, added by the 2021 'Ley Rider' law that already required platform employers to disclose algorithmic logic to worker representatives, years before the EU AI Act's own high-risk employment provisions existed. Spain is enforcing a national transparency rule it had already built, not implementing the EU's Annex III framework.

The EU's own Annex III guidelines remain in draft specifically because the Digital Omnibus Package pushed the compliance deadline to December 2027, creating an eighteen-month window in which national laws like Spain's, and enforcement moves like Germany's Bundesrat, are setting practical standards Brussels has not yet finalised.

What could happen next?
  • Meaning

    Spain's ruling enforces a national transparency law from 2021, not the EU AI Act, showing national rules are setting workplace-algorithm disclosure standards ahead of Brussels' own guidelines.

  • Risk

    Multinationals face inconsistent disclosure obligations across EU member states until the Commission finalises Annex III guidance, currently delayed to December 2027.
