Federal Court on Twitter | August 5, 2022:

Documents filed in Federal Court are public, unless there is a confidentiality Order. Due to the interest in the matter of Karl Harrison et al. v Attorney General, all documents have been posted to the Court’s website: https://fct-cf.gc.ca/en/court-files-and-decisions/court-files.
