Comparative Study Of Identity Theft And Online Scams
Effectiveness of GDPR Enforcement in Criminal Investigations
The General Data Protection Regulation (GDPR), enforced in the EU since May 2018, governs the processing of personal data, even in criminal investigations, while balancing law enforcement needs and privacy rights. Its effectiveness can be assessed through:
Protection of individuals’ data rights
Accountability of law enforcement agencies
Clear legal frameworks for data processing
Sanctions for non-compliance
GDPR enforcement intersects with criminal investigations under specific rules (e.g., Article 23, Article 6, and Law Enforcement Directive 2016/680), which allow data processing for criminal purposes while imposing strict oversight.

Key Principles Derived from These Cases
GDPR applies to law enforcement indirectly and directly:
Even in criminal investigations, personal data must be processed under lawful basis and purpose limitation.
Cross-border data transfer is highly regulated:
Schrems II and Fashion ID demonstrate that criminal investigations involving foreign authorities must ensure GDPR-level protections.
Accountability and oversight:
CNIL and EDPB guidelines highlight that public authorities and intermediaries must implement technical and organizational safeguards.
Data minimization and retention limits:
Breyer and Austrian Supreme Court show enforcement is effective in preventing excessive or unauthorized retention.
Effective enforcement through fines and corrective actions:
GDPR provides powerful tools for authorities to penalize non-compliance, ensuring law enforcement agencies and private companies comply.
Conclusion
GDPR enforcement in criminal investigations is effective when it:
Protects individual privacy rights
Limits unauthorized cross-border transfers
Encourages accountability of law enforcement and intermediaries
Ensures data minimization, retention limits, and lawful basis
Judicial decisions across Europe have demonstrated that GDPR is not a barrier to criminal investigations, but a framework that ensures lawful, proportionate, and accountable processing.
