Breach Multi Jurisdiction

Principle 3: Parallel Execution Tracks

Manage notifications through parallel workstreams:

Track 1: EU/UK GDPR (72-hour priority)

• Lead SA notification within 72 hours
• Phased notification under Art. 33(4) if investigation is ongoing
• Art. 34 data subject notification within 7 days of high-risk determination

Track 2: US State Notifications (varies by state)

• AG notifications for each state where affected residents reside
• Individual notifications per state-specific requirements
• Substitute notice where individual notification is not feasible

Track 3: Other International Jurisdictions

• OAIC notification (Australia) within 30 days
• OPC notification (Canada) as soon as feasible
• Other jurisdictions as applicable

Lead Supervisory Authority Determination

For Stellar Payments Group with main establishment in Berlin, Germany:

• Lead SA: Berliner Beauftragte für Datenschutz und Informationsfreiheit
• Concerned SAs: Any SA in an EU member state where affected data subjects reside
• One-stop-shop mechanism: The lead SA coordinates with concerned SAs under Art. 60
• Exception: If the breach relates solely to an establishment in another member state, or substantially affects data subjects only in that state, the local SA may be the competent authority under Art. 56(2)

Notification Coordination Checklist

Pre-Notification (Within 24 Hours of Awareness)

• Determine which jurisdictions are affected based on data subject residency analysis
• Map applicable notification laws for each jurisdiction
• Identify the shortest notification deadline and set as primary driver
• Assign jurisdiction-specific notification leads (EU: DPO; US: General Counsel; APAC: Regional Privacy Manager)
• Engage external counsel in each jurisdiction as needed

EU/UK Track (72-Hour Deadline)

• Identify lead SA and prepare notification form
• Complete Art. 33(3) content requirements
• Submit notification to lead SA within 72 hours
• If cross-border, inform lead SA that multiple member states are affected
• Prepare Art. 34 data subject notification in languages of affected member states

US Track (Varies by State)

• Determine affected residents per state using postal/billing addresses
• For each state with 500+ affected residents, prepare AG notification
• Draft individual notification letters per state content requirements
• Include credit monitoring offer where required (SSN/financial data states)
• Engage outside US counsel for state-specific compliance review
• Submit AG notifications per each state's required timeline
• Dispatch individual notifications per each state's required timeline

International Track

• Prepare OAIC notification (Australia) within 30 days
• Prepare OPC notification (Canada) "as soon as feasible"
• Assess other jurisdictions (Brazil, Japan, South Korea, Singapore) based on affected populations
• Engage local counsel for jurisdiction-specific requirements

Coordination with Law Enforcement

In some jurisdictions, law enforcement authorities may request a delay in data subject notification to avoid prejudicing a criminal investigation:

• EU: EDPB Guidelines 9/2022 acknowledge that law enforcement may request delay; the controller should document the request and comply while still notifying the SA within 72 hours.
• US: Many state laws explicitly permit delay at law enforcement request. The delay must be documented and notification must proceed promptly upon law enforcement clearance.
• Best practice: Always notify the supervisory authority/AG on time even if data subject notification is delayed at law enforcement request.
