The regulations of data protection do not block the access of the claimant to the information about the persons missings disappeared with judicial declaration from death or demise that figure in the data base of the Census of persons during the Civil War. In the case of disappeared persons with respect to whom judicial declaration does not consist of death or demise and who could be alive, the regulations of data protection would not block the access to the data that they figure in the portal of open data whenever this information does not allow the identification of the affected persons. To these effects, a generalized and indiscriminate access to the name and surnames of these persons is not considered necessary to attain the purpose of transparency.
