Impossibility of adoption: The phrase “a child who cannot be legally adopted” in staff rule 3.6 is applicable only in the absence of any adoption system whatsoever in the country, be it in the civil courts or customary courts.Legitimate expectation: Legitimate expectation may result in the creation of an enforceable legal right, although the application of the doctrine is subject to a number of qualifications. A legitimate expectation giving rise to contractual or legal obligations occurs where a party acts in such a way, by representation by deeds or words, that is intended or is reasonably likely to induce the other party to act in some way in reliance upon that representation, and the other party does so. Where a staff member claims that she had a legitimate expectation arising from a promise made by the Administration, such expectation must not be based on mere verbal assertions, but on a firm and express commitment made individually to the staff member by a competent authority of the Administration.
