Under the Immigration and Refugee Protection Act, hearings before the IRB are generally held in public. A case may be heard in private when there is a serious possibility that the life, liberty and security of a person will be endangered if the proceeding is held in public, or for reasons of fairness or public security, as set out in section 166 of the Act.
When a case is heard in private, the decision and reasons are "sanitized". That is, all the information that could identify the person who is the subject of the proceedings is replaced by "XXX".
