Section 133 allows bilingualism in both the federal Parliament and the Quebec legislature, allows for records to be kept in both languages, and allows bilingualism in federal and Quebec courts. Interpretation of this section has found that this provision requires that all statutes and delegated legislation be in both languages and be of equal force. Likewise, it has been found that the meaning of "courts" in Section 133 includes all federal and provincial courts as well as all tribunals that exercise an adjudicative function.
