“Courts and commentators have sometimes said the administrative law doctrine of legitimate expectations is incoherent. They say that the various ways of acquiring a legitimate expectation do not hang together; nothing unifies them. For example, Lord Brown in Paponette v Attorney General of Trinidad and Tobago agreed with a commentator’s description of the doctrine of legitimate expectations as a mere ‘patchwork’ and ‘little more than a mechanism to dispense palm-tree justice’. Both Richard Clayton and Mark Elliott have in the past favoured the ‘disaggregation’ of the doctrine.”
