A data breach at Wexford County Council in 2019, initially appearing as a routine inquiry from then-Councillor Fionntán Ó Súilleabháin, has resulted in a legal challenge. A woman discovered her confidential records were released without her consent after a request made by Ó Súilleabháin on behalf of a constituent. The recipient of the files is a Sinn Féin activist and the brother of a former Provisional IRA bomber. The council has acknowledged the breach and issued an apology to the affected woman. Now a TD, Ó Súilleabháin is facing legal action, but Sinn Féin leader Mary Lou McDonald has publicly supported him. The Irish Independent’s investigation details the incident and its implications.
