Notwithstanding its independence, the relationship between the college and the university is symbiotic. The university's council approves the appointment of the college's principal (this is chiefly because the principal is an "ex officio" member of Senate). If pressed this would effectively amount to a veto, but short-lists are invariably constructed in dialogue with the university. Again, though the university council does not have the power to approve or disapprove of any changes to the college's constitution, the college, in accepting recognition by the university, agrees to "notify" the university of any such changes. If those changes unfavourably affect the college's status in the university, recognition can be withdrawn, which is to say the college would remain but it would no longer be able to admit students to the university.
