Handling of Restricted Data Subject Rights

GDPR Article 23 permits the restriction of data subject rights and controller obligations through EU or Member State law. These restrictions apply when necessary to safeguard important public interests, national security, criminal investigations, or the rights and freedoms of others.

Yes, an organization can refuse a data subject access request if a specific legislative measure under Article 23 applies. The refusal must be necessary, proportionate, and legally justified, such as when providing access would obstruct a criminal investigation.

Acceptable legal grounds include national security, defense, public security, the prevention or prosecution of criminal offenses, judicial independence, and important economic or financial interests of the EU or a Member State.

Article 23 allows restrictions on the obligations and rights provided in Articles 12 to 22, Article 34 regarding breach notification, and Article 5 principles, but only insofar as Article 5 corresponds to the rights in Articles 12 to 22.

Any restriction must respect the essence of fundamental rights and freedoms. It should only limit rights to the minimum extent required to achieve the specific safeguarding objective, without imposing excessive burdens on the individual.

Organizations must retain detailed records in a data subject request log, including the specific request, the legal basis for restriction, the scope of the limitation, and the justification explaining why the restriction was necessary and proportionate. Tools like WatchDog Security's Compliance Center can help standardize evidence capture and highlight gaps (e.g., missing legal basis or approvals) for restricted-request records.

Generally, data subjects should be informed about the restriction and the reasons for it. However, this notification can be withheld if providing it would be prejudicial to the purpose of the restriction, such as tipping off a suspect in a fraud investigation.

Article 23 empowers individual EU Member States to enact their own national laws providing specific exemptions to DSARs. Organizations must rely on these specific national legislative measures when applying a restriction.

The record should include the purposes of the processing, categories of personal data, scope of the restriction, applicable safeguards, risks to the data subject, and the specific legislative measure authorizing the restriction.

Teams should implement a formalized data subject request log that captures the exact legal rationale, approvals from legal counsel, and the communication provided to the user. This ensures all restricted requests have an auditable trail of evidence for regulators.

Article 23 decisions should be traceable: what legal measure applies, what scope is limited, who approved it, and why it was necessary and proportionate. Tools like WatchDog Security's Compliance Center can help centralize the control requirements and evidence expectations, while WatchDog Security's Secure File Sharing can be used to share supporting legal justification and approvals with restricted access and audit logs.

An auditable trail typically separates the decision record (dates, scope, legal basis, approver) from sensitive supporting materials (investigation notes, security context) with tight access control. Tools like WatchDog Security's Risk Register can track the rationale and residual risk for applying restrictions, and WatchDog Security's Secure File Sharing can store sensitive attachments with access controls and downloadable audit logs.
