 Callinan's resignation coincided with the outbreak of two other scandals; allegations that the Garda Síochána Ombudsman Commission (GSOC) was under surveillance by an unknown group which had used "government-level technology" following a counter-surveillance operation undertaken by a British private security firm, and the emergence that phone calls in Garda stations throughout the country had been recorded on a mass scale for over 30 years before the practice was brought to an end.The government in April 2014 established a commission of investigation into Callinan's resignation and these other issues.It is commonly called the Fennelly Commission after its sole member, Nial Fennelly, a retired justice of the Supreme Court.
