There has been a further delay by the European Commission in its response to an EU Ombudsman investigation into the monitoring of data protection regulations in Ireland.

The Commission had been asked to provide information by 15 May but told the Ombudsman's office that it needed an additional ten days.

The Commission has now requested an extension to the deadline and is expected to reply by 30 June.

In February, Ombudsman Emily O'Reilly opened an inquiry into how the European Commission has been monitoring the application of GDPR in Ireland.

It followed a complaint to her office from Dr Johnny Ryan, a senior fellow at the Irish Council for Civil Liberties.

In a letter to European Commission President Ursula von der Leyen, Ms O'Reilly said that the complainant had expressed the concern that the Commission has not gathered sufficient information to monitor the application of GDPR in Ireland.

"Public bodies, along with civil society organisations, report that the application of the GDPR in Ireland is inadequate, whereas the commission's recent reply to the complainant in this case appears to suggest that there is no evidence of this," the letter stated.

Ms O'Reilly said that questions were bound to arise in the minds of citizens if different factual accounts were circulating regarding the implementation of GDPR.

The European Commission was asked to provide a "detailed and comprehensive account" of the information that it has so far collected to inform itself as to whether GDPR is being applied in all respects in Ireland.

The General Data Protection Regulation is an EU regulation that came into effect in May 2018 which imposes strict requirements on the collection, use and storage of personal data.
