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:

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

 


Frequently Asked Questions about Article 5

+ What are the seven principles of the GDPR?
Lawfulness, fairness and transparency; purpose limitation; data minimisation; accuracy; storage limitation; integrity and confidentiality; and accountability. The first six are in Article 5(1)(a)–(f), the seventh in Article 5(2).
+ What is data minimisation under Article 5?
Data minimisation (Art. 5(1)(c)) requires personal data to be adequate, relevant and limited to what is necessary for the stated purpose. In practice: do not collect a field you cannot justify.
+What is the maximum fine for breaching Article 5?
Up to €20 million or 4% of total worldwide annual turnover of the preceding financial year, whichever is higher (Art. 83(5)(a)). Article 5 sits in the upper fine tier.
+Does Article 5 apply to processors?
Article 5 addresses controllers. Processors are bound indirectly through the Article 28 contract and directly through Article 32 (security). Authorities have fined processors for security failures that also breached Art. 5(1)(f).
+How is Article 5 different from Article 6?
Article 5 sets the principles; Article 6 lists the six legal bases that satisfy the “lawfulness” principle in Art. 5(1)(a). You need both: a legal basis under Art. 6 and compliance with all seven principles under Art. 5.
+How long can personal data be stored under Article 5?
No fixed period. Art. 5(1)(e) requires deletion or anonymisation once the purpose is fulfilled, unless a legal retention obligation applies. Controllers must set and document a retention period per purpose.
