Publication bans are court orders. They may prohibit the publication or disclosure of certain information in otherwise open court proceedings. For example, a ban might prohibit the publication of any information that would identify a particular witness or victim in a criminal proceeding. A ban might also prohibit the publication of any details or evidence disclosed at a bail hearing.
The Court of Appeal will not publish reasons for judgment on its website without ensuring that information that is subject to a publication ban has been removed or redacted from the judgment (eg. through the use of initials).
Publication bans and their application are explained in Section 1.3 of the Court of Appeal Record and Courtroom Access Policy.
A useful list of bans and their effect may be found in Appendix "B" of the Access Policy.
