Legitimate expectations also have begged the question whether unincorporated treaties creates a legitimate expectation that the future executive will legislate in such a way that is compatible with the international obligation. These legitimate expectations are a public law product as a decision maker creates a legitimate expectation so that a person that is affected by his actions is to be treated in a way that is consistent to that expectation. This was dealt and dismissed by the Court of Appeal in Chundawadra v Immigration Appeal Tribunalas it could not have been consistent to introduce the ECHR into domestic law without consulting Parliament and so creating a legitimate expectation. In the Australian case of Minister of State for Immigration v Teoh, the majority held that ratification of an international treaty by the Executive was a positive act and that all state organs must act in accordance with it and so a legitimate expectation was formed. However, in the UK, this approach was declined and ratification of an international treaty could not create a legitimate expectation. Sales and Clement state that this is so for the following reasons. First, ratification and the timetable for implementation is a matter for Parliament. Secondly, the changing of domestic law is limited to the legislative and the judiciary, not the executive. Allowing the executive to grant legitimate expectations for ratified international treaties would be contrary to this constitutional principle. Thirdly, translating international obligations of the UK into domestic law via legitimate expectations does not support principles of certainty as many are unsure of what is legitimate expectation and what is not.
