The application of the general limitations of fundamental rights to data protection pursuant to Article 52, paragraph 1 of the EU Charter of Fundamental Rights, has raised interesting questions. According to this provision, limitations must be provided for by law, must return to the essence of the law concerned and, subject to the principle of proportionality, must be necessary and genuinely meet the general interest objectives recognized by the European Union or the need to protect the rights and the freedoms of others. We ask ourselves the question, can these limitations justify the unfair processing of personal data or the processing for purposes not covered by the legal basis for the collection, storage and disclosure of personal information at this stage of the prosecution under special investigative measures? From this question we started to write this article which consists in identifying in the framework of special investigative measures the breaches of personal data breaches and proposals for amendments in order to comply with this protection.
