According to the Hungarian Constitution in this case the Parliament shall debate the law again and hold another vote on its passage. If adopted for the second time the President of the Republic is required to ratify and promulgate the law within a period of five days.
The main concern of the President was the unsatisfactory level of data protection provided by the Agreement. He believed that it is ambiguous whether the adequate level of protection for personal data is ensured, although it does not mean that the Agreement necessarily restricts, in an unconstitutional manner the protection of personal data. The President stressed that the Hungarian Act ratifying the Agreement shall make it clear: the guarantees of the Hungarian Data Protection Act are upheld. According to his proposal this requirement can be satisfied by the ratifying Act allowing the transfer of personal data only on condition of the data subject’s consent. This provision would not contravene the Agreement as it states ‘this Agreement is not intended to derogate from or amend legislation of the United States of America or the European Union or its Member States’.
