Evidence Listing

The Inquiry will publish evidence after it has been adduced at hearings.

Witness statements and any other documentary evidence will be published here. Oral evidence (videos and transcripts) can also be found here, under the relevant witness, and via our Hearings page. Content will usually be available within 24 hours of an evidence session taking place.

Use the filters below to search for specific pieces of evidence.

Some of the evidence published here may contain content which people may find distressing. The wellbeing of people participating in the Inquiry is extremely important to the Inquiry. 

In the context of the Inquiry's processes, free, confidential, emotional and psychological support services are available from PAM Wellness, for witnesses, their supporters and participants in the Inquiry. For advice on coping with traumatic events, or information on how to access these services please see here.
