GDPR Article 77 — Right to lodge a complaint with a supervisory authority

What this control requires

Ensure data subjects can lodge complaints with a supervisory authority in their Member State of residence, work, or alleged infringement if personal data processing violates GDPR. The authority must inform complainants of progress and outcomes, including judicial remedy options under Article 78. This control addresses Remedies, Liability and Penalties.

In plain English

Ensure data subjects can lodge complaints with a supervisory authority in their Member State of residence, work, or alleged infringement if personal data processing violates GDPR. In practice, this means you can prove you right supervisory authority-level controls on a defined cadence.

Why it matters

GDPR administrative fines reach the greater of €20 million or 4% of global annual turnover. The European Data Protection Board (EDPB) coordinates supervisory-authority enforcement across the EU/EEA, and DPAs publish enforcement decisions citing specific Articles.

What an auditor looks for

A DPA or privacy auditor expects: a Records of Processing Activities (RoPA) entry, a documented lawful basis, evidence the Article's data-subject right is operationalised end-to-end, a named DPO contact (where required), and Article 30 records that match what the front-end actually does.

Within Chapter VIII: Remedies, the assessor will trace your implementation back to the catalogue reference (Article Article 77) and look for objective evidence on the latest two assessment cycles.

How to implement

Policy Management

Docs. Keep each policy in version-controlled Markdown alongside the code that implements it; ship a signed PDF snapshot at each annual review and link the SHA into the SoA.

Operational checklist
