### **Overview**

This article ensures that individuals have the right to an effective judicial remedy against a supervisory authority’s legally binding decision or if the authority fails to act on a complaint within three months. Legal proceedings must be initiated before the courts of the Member State where the supervisory authority is established.  
  

### **Key Principles**

-   Judicial Access: Individuals can challenge decisions or inaction by supervisory authorities.
    
-   Timely Action: Remedies apply if the authority fails to act on complaints within three months.
    
-   Jurisdiction: Legal proceedings are brought before the courts in the Member State of the relevant supervisory authority.
    
-   Accountability: Ensures supervisory authorities remain responsible for timely and lawful actions.
    
-   Transparency: Individuals are informed of their right to seek judicial review.  
      
    

### **Organizational Applicability**

-   Develop a process to respond efficiently to judicial inquiries or proceedings.

### **Periodic Review**

-   Frequency: Annually or when procedures, laws, or complaint handling processes change.
    
-   Responsible Role: Supervisory authority leadership, Compliance Team, or Legal.
    
-   Outcome: Ensure data subjects’ rights to judicial remedies are protected and authorities act within timelines.  
      
    

### **Non-Compliance Risks**

-   Fines: Up to €20 million or 4% of global annual turnover for supervised entities failing GDPR obligations.
    
-   Legal Exposure: Judicial challenges due to delayed or inadequate action on complaints.
    
-   Reputational Damage: Loss of trust in the authority’s responsiveness and GDPR enforcement.
