Article 6(1)(c) and (e) of Regulation 2016/679, read in conjunction with Article 86 of that regulation,must be interpreted as not precluding national case-law which requires a controller, being a public authority responsible for reconciling public access to official documents with the right to the protection of personal data, to inform and consult the natural person concerned prior to the disclosure of official documents containing such data, provided that such an obligation is not impossible to implement and that it does not require disproportionate effort and, therefore, it does not result in a disproportionate restriction on public access to those documents.
