The inquiry was set up in response to the
Inquiry into Historical Institutional Abuse Act (Northern Ireland) 2013 (c. 2 (N.I.)). Following a request to extend its timescale, the inquiry's report was delivered to the
First Minister and deputy First Minister (who had no powers to change it) on 6 January 2017, shortly before the deadline of 18 January, and published on 20 January. In October 2019 the House of Lords passed the Historical Institutional Abuse (Northern Ireland) Bill "to establish the Historical Institutional Abuse Redress Board and confer an entitlement to compensation...", and it was passed by the House of Commons as one of its last acts before the
2019 United Kingdom general election. In the 2019
New Year's Honours list, the Secretary of the Inquiry, Andrew Browne, was made
OBE for his services to victims and survivors of abuse, while Paula Dawson was made
MBE for her services to public inquiries. In May 2020 Interim Advocate for Survivors of Historical Abuse Brendan McAllister office leaked the personal and private details of approximately 250 Survivors of Historical abuse in an emailing data breach error and as a result McAllister faced widespread calls to resign from the two oldest and largest Survivor groups the Saint Patrick's Survivors and SAVIA alongside many other independent survivors having lost trust in the Interim Advocate. In June 2020 Interim advocate Brendan McAllister was called to resign again after victims accused him of having a "conflict of interest", after he was ordained as a Deacon in the
Catholic Church. McAllister assisted in liturgy at Saint Peters Church in Warrenpoint as part of the Down and Conner Diocese, despite the HIA Inquiry having found that the Diocese of Down and Conner failed to raise concerns about serial child abuser
Father Brendan Smyth, and did not inform social services or the police. ==Scope of inquiry==
