This control addresses Data Classification. > > — GDPR, Article Article 9 ### In plain English Prohibits processing special categories of personal data (e.g., racial, health, biometric) unless based on explicit consent, legal obligations, vital interests, or public interest with safeguards. In practice, this means you can prove you principles consent-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. This control is rated **critical** in the source catalogue. Treat gaps here as production incidents in the risk register, not housekeeping. ## 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 II: Principles**, the assessor will trace your implementation back to the catalogue reference (Article Article 9) 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 - **Principles.** Document the trigger, the owner and the cadence. - **Data.** Document the trigger, the owner and the cadence. - **Safeguards.** Document the trigger, the owner and the cadence. - **Obligations.** Document the trigger, the owner and the cadence. - **Scope:** consent, legal obligations. ## Evidence to collect - **Policy Document.** A signed and version-controlled policy / standard / procedure document. Signed policy or standard documents the safeguard. Focus: Processing of special categories of personal data. ## Common pitfalls - Policies that no engineer has read; the version in Confluence drifts from the version that's actually being enforced. ## How it maps to other frameworks Computed from shared tags, control component and key-operation subjects — handy when you are reconciling controls across an audit. - [**ISO/IEC 27701:2025 A.1.3.2** — Comply with obligations](https://support.icompaas.com/compliance/iso-27701-2025/a-1-3-2-comply-with-obligations) - [**India DPDP Act 2023 DS-005** — Consent Withdrawal Mechanism](https://support.icompaas.com/compliance/india-dpdp-act-2023/ds-005-consent-withdrawal-mechanism) - [**SOC 2 (2017 TSC) P3.2** — Consent Management for Personal Information Collection](https://support.icompaas.com/compliance/soc-2-trust-services-criteria/p3-2-consent-management-for-personal-information-collection) - [**NIST SP 800-53 Rev. 5 PM-24** — Data Integrity Board](https://support.icompaas.com/compliance/nist-sp-800-53-rev-5/pm-24-data-integrity-board) ## Related controls in GDPR - [**Article Article 6** — Lawfulness of processing](https://support.icompaas.com/compliance/gdpr/article-6-lawfulness-of-processing) - [**Article Article 7** — Conditions for consent](https://support.icompaas.com/compliance/gdpr/article-7-conditions-for-consent) - [**Article Article 8** — Conditions applicable to child's consent in relation to information society services](https://support.icompaas.com/compliance/gdpr/article-8-conditions-applicable-to-child-s-consent-in-relation-to-information-society) - [**Article Article 4** — Definitions](https://support.icompaas.com/compliance/gdpr/article-4-definitions) - [**Article Article 17** — Right to erasure ('right to be forgotten')](https://support.icompaas.com/compliance/gdpr/article-17-right-to-erasure-right-to-be-forgotten) - [**Article Article 10** — Processing of personal data relating to criminal convictions and offences](https://support.icompaas.com/compliance/gdpr/article-10-processing-of-personal-data-relating-to-criminal-convictions-and-offences) ## References - [European Union — GDPR](https://eur-lex.europa.eu/eli/reg/2016/679/oj) - Catalogue identifier: `Article Article 9` Topics: governance riskpolicy managementprivacy management ## Related compliance guidance - [GDPR compliance: a practical implementation guide for cloud-native SaaS teams](https://support.icompaas.com/compliance/gdpr): Start with the full GDPR implementation guide — scope, roadmap, evidence and how the assessment runs. - [ISO/IEC 27001:2022 compliance: a practical implementation guide](https://support.icompaas.com/compliance/iso-27001-2022): The security management system most EU procurement teams ask for alongside a DPA; its controls supply much of the Article 32 evidence. - [India's DPDP Act 2023: a practical compliance guide for cloud teams](https://support.icompaas.com/compliance/india-dpdp-act-2023): If engineering or support teams sit in India, the same data flows are also subject to India’s Digital Personal Data Protection Act.
