Recital (44)

Member States should be able to adopt legislative measures delaying, restricting or omitting the information to data subjects or restricting, wholly or partly, the access to their personal data to the extent that and as long as such a measure constitutes a necessary and proportionate measure in a democratic society with due regard for the fundamental rights and the legitimate interests of the natural person concerned, to avoid obstructing official or legal inquiries, investigations or procedures, to avoid prejudicing the prevention, investigation, detection or prosecution of criminal offences or the execution of criminal penalties, to protect public security or national security, or to protect the rights and freedoms of others. The controller should assess, by way of a concrete and individual examination of each case, whether the right of access should be partially or completely restricted.
