‘Every data processing activity requires a lawful basis. Such lawful basis may be provided directly by law, or by consent granted by the data subject, both according to the statutory requirements set out in the Directive 95/46/EC and, importantly, national data protection laws. This general principle remains unchanged under the GDPR, however, the new Regulation provides for new or additional requirements for such consent to be a lawful basis for processing and transfer of personal data.’
