While you have a right to access your personal data, this right is not absolute. A Controller may limit this right in specific situations to balance data access with other important considerations like safety and legal compliance. Access restrictions may include setting time frames for when you can exercise this right. 

A Controller can limit your access in the following cases: 

• To Prevent Harm: If restricting access is necessary to protect you or other individuals from harm, as specified by the Regulations. 

• Public Entity Requirements: If the Controller is a public entity, access may be limited if required for security purposes, to comply with another law, or to fulfill judicial requirements. 

Yes, there are specific situations where a Controller is legally required to prevent you from accessing your personal data. The law mandates that a Controller shall prevent access in any of the circumstances outlined in Paragraphs (1) through (6) of Article (16) of the law. While the provided text does not detail the specific scenarios listed in Article (16), it establishes that a complete denial of access is required under those conditions.
