Bylaws in brief are the documents that the EUS is legally responsible for upholding. This has not been reflected in practice. Conversely, policies are documents that are guiding principles and best practices- a lot of what are identified as bylaws below are not only not currently binding by Quebec Law, they're better off relabeled as policies.
This is reflected in the creation of the Board of Governors and the constitutional amendments made in the Winter 2017 Referendum.
