What’s next for the Inquiry?
The Inquiry's Chair, Sir Wyn Williams will publish Volume 1 of his final report in July.
This volume will focus on redress (compensation) and the human impact of the Horizon scandal.
Moving forward, the Inquiry will continue analysing evidence, drafting the final report, as well as the process of Maxwellisation. This is where, under Rule 13 of the Inquiry Rules 2006, the Inquiry needs to give anyone who is criticised in the report a reasonable opportunity to respond.
The Inquiry is also working to publish exhibits contained within written statements/expert reports as well as any additional documents referenced during hearings.
We will also ensure that, as the Inquiry concludes, there is a comprehensive and well-ordered record of the Inquiry which will be transferred to The National Archives.
In a statement, Sir Wyn Williams, Chair of the Inquiry, said: “People have waited long enough to hear the truth about events that had such adverse consequences on their lives. So, I am determined to provide answers to those directly affected as swiftly as possible."
In Your Own Words: Family and Relationships Paper
The Inquiry's listening project, In Your Own Words, gives people affected by the scandal a platform to share their stories and experiences.
In Your Own Words has just published its first paper, which focuses on how people’s relationships and family life were impacted by the Horizon scandal.
