Art. 5 GDPR – Principles relating to processing of personal data
In shortArticle 5 GDPR sets the seven principles every organisation must follow when handling personal data: lawfulness, fairness and transparency; purpose limitation; data minimisation; accuracy; storage limitation; integrity and confidentiality; and accountability. Breaching Article 5 carries the highest GDPR fine tier – up to €20 million or 4% of global annual turnover.

The seven principles of Article 5 explained
Article 5(1) lists six principles and Article 5(2) adds accountability, making seven in total. Each principle imposes a concrete obligation on the controller.
| Principle | What it means | What you must have in place |
|---|---|---|
| 1. Lawfulness, fairness, transparency Art. 5(1)(a) | Every processing activity needs a legal basis (Art. 6) and people must be told about it in plain language. | Documented legal basis per activity; privacy notice meeting Art. 13/14 |
| 2. Purpose limitation Art. 5(1)(b) | Collect data for a stated purpose; do not reuse it for something incompatible. | Purpose recorded per activity in the ROPA (Art. 30); compatibility test for new uses |
| 3. Data minimisation Art. 5(1)(c) | Only collect and keep the data actually needed for the purpose. | Field-level review of forms and systems; justification for each data category |
| 4. Accuracy Art. 5(1)(d) | Keep data correct and current; fix or delete inaccurate data promptly. | Rectification process (Art. 16); periodic data quality checks |
| 5. Storage limitation Art. 5(1)(e) | Do not keep identifiable data longer than the purpose requires. | Retention schedule with deletion triggers, applied per system |
| 6. Integrity and confidentiality Art. 5(1)(f) | Protect data against loss, misuse and unauthorised access. | Security measures under Art. 32; access control; breach procedure (Art. 33) |
| 7. Accountability Art. 5(2) | The controller must be able to prove compliance with all of the above. | ROPA, DPIAs, policies, training records, DPO where required (Art. 37) |
Fines issued under Article 5
Article 5 is the most-cited article in GDPR enforcement because almost every breach also violates a principle. Selected decisions:
| Organisation | Authority | Date | Fine | Principle breached |
|---|---|---|---|---|
| Clearview AI | CNIL (France) | Oct 2022 | €20.000.000 | Lawfulness – facial images scraped without legal basis |
| Meta Platforms Ireland | DPC (Ireland) | May 2023 | €1.200.000.000 | Lawfulness – transfers to the US without adequate safeguards |
| Free Mobile | CNIL (France) | Dec 2022 | €300.000 | Integrity and confidentiality; accuracy |
| Deutsche Wohnen | Berlin DPA (Germany) | Oct 2019 | €14.500.000 | Storage limitation – tenant data kept without deletion routine |

Recitals that explain Article 5
Recitals are not binding, but courts and authorities use them to interpret the article.
- Recital 39 – Principles of data processing
Explains transparency, minimisation, storage limitation and security, and requires that processing be “reasonably expected” by the data subject. - Recital 40 – Lawfulness of data processing
Confirms that processing is lawful only with consent or another legal basis set out in the Regulation or in EU/Member State law.
What Article 5 requires in practice
Under Art. 5(2) the controller must be able to demonstrate compliance. Supervisory authorities typically expect the following documentation:
- Maintain a record of processing activities (ROPA) with purpose, legal basis, data categories and retention per activity
- Publish a privacy notice that matches the ROPA
- Run a DPIA for high-risk processing (Art. 35)
- Apply a retention schedule with automated deletion
- Document security measures and test them
- Keep evidence: policies, training logs, DPIA outcomes, vendor DPAs
