GDPR Weekly Dispatch: Cross-Border Complaints Streamlined & TikTok Under Fire

Dec 17, 2025

🚨 Headline Story: EU Streamlines Cross-Border GDPR Complaints

The Council of the European Union has adopted a new regulation designed to accelerate the processing of cross-border GDPR complaints. This long-awaited reform establishes uniform admissibility criteria, defines clear rights for complainants and investigated parties, and introduces a simplified cooperation procedure.

Key provisions include strict investigation deadlines: 15 months for standard cases and 12 months for simpler ones. This addresses one of the most significant criticisms of the GDPR enforcement mechanism—the "bottleneck" effect where cross-border cases languish in procedural limbo for years. The new law aims to harmonize procedural rules across Member States, ensuring that the "One Stop Shop" mechanism functions as originally intended.

Why it matters:
For businesses operating across the EU, this means faster resolution of complaints but potentially more aggressive enforcement timelines. The era of indefinite delays in cross-border investigations may be coming to an end. Companies should expect quicker inquiries and stricter adherence to procedural deadlines from Lead Supervisory Authorities.

💡 Opinion & Analysis

  • The "One Stop Shop" Reboot: With the new cross-border rules, we might finally see the "One Stop Shop" mechanism work efficiently. However, the 15-month deadline is ambitious. DPOs should prepare for a potentially faster cadence of regulatory queries in 2026.
