def can_update_banks(self):

Tests if this user can update ``Banks``.

        A return of true does not guarantee successful authorization. A
        return of false indicates that it is known updating a ``Bank``
        will result in a ``PermissionDenied``. This is intended as a
        hint to an application that may not wish to offer update
        operations to unauthorized users.

        return: (boolean) - ``false`` if ``Bank`` modification is not
                authorized, ``true`` otherwise
        *compliance: mandatory -- This method must be implemented.*
