All Birkbeck Students' Union Clubs & Societies must have an up-to-date constitution that has been agreed by their members at the group's AGM; this constitution will be viewed as the body of fundamental principles according to which the society will be governed & should be referred to at all times when procedure is not clear. This model constitution is designed in line with all BBKSU rules & regulations; changes to the pro-forma of this document must be discussed with the Students' Union before they can be offered to the membership.
