Article 61 of Regulation (EU) 2024/1689 — Informed consent in real-world testing. Official text, practical interpretation, key obligations and compliance implications.

Article 61 sets the consent floor for testing high-risk AI systems in real-world conditions under Article 60: no subject participates without freely given, informed consent. It transposes a clinical-trials instinct into AI testing.

Official Text Summary

Before taking part in real-world testing under Article 60, subjects must give freely given informed consent, obtained after they receive concise, clear, relevant and understandable information about the nature and objectives of the testing, the conditions of participation and its expected duration, their rights and the guarantees attached — notably the right to refuse to participate and the right to withdraw at any time without giving reasons and without suffering any detriment — and the arrangements for requesting reversal or disregard of the system's outputs. Consent must be dated and documented, and a copy given to the subject or their legal representative.

Key Obligations

Compliance Timeline

Applies from 2 August 2026; the 2026 Digital Omnibus deferred the substantive high-risk obligations (Annex III to 2 December 2027, Annex I to 2 August 2028) but did not move this provision.

Frequently Asked Questions

Yes, at any time, without justification and without detriment. Withdrawal ends future participation but does not require deleting what was lawfully collected up to that point — data protection rules govern the collected data.

Article 61 consent is a testing-participation safeguard, not a legal basis for data processing. Where personal data is processed during testing, a valid GDPR basis is needed separately, and both sets of information duties must be satisfied.
