“In most instances where a discretionary power is conferred it would be wrong for the decision maker to frame a rule in absolute terms because to do so would defeat the statutory purpose. However, it seems to me that there are certain exceptional statutory contexts “where a policy may lawfully exclude exceptions to the rule because to allow exceptions would substantially undermine an important legislative aim which underpins the grant of discretionary power to the authority.”
