legitimate as they fall within the scope of powers of the particular public body. Representations will not lead to legitimate expectations when delegation of such power to the individual making the representation is forbidden by statute, or where the individual making the representation lacks actual or apparent authority. In the latter case, the applicant's expectation will lack legitimacy and thus would prima facie not be binding on the public authority. Reasonableness of the expectation In deciding whether the expectation held by the aggrieved party is legitimate, the courts will consider whether the expectation was, in all circumstances, reasonable when it was formed. The reasonableness test requires the court to assess the behaviour of the parties in the events which occurred prior to the making of the alleged representation, according to the following criteria: The representation may arise from either the words used or the behaviour of the parties. The aggrieved party must not have utilized fraudulent measures to obtain the representation, and must have disclosed all relevant information. The representation must usually be "clear, unambiguous and devoid of all relevant qualification". However, this is not required to establish the existence of a legitimate expectation if the public authority acted so unfairly such that its conduct constituted an abuse of power. The number of individuals affected may play a part, as courts have found a legitimate expectation to exist when the representation was "pressing and focused" and made to a small group of individuals. On the other hand, courts rarely find the existence of a legitimate expectation when the representation was one made in general terms to a large and diverse group of individuals. However, it may be noted that there are instances where an individual has successfully sought relief on behalf of a sizeable group of people. Reliance and detriment as consideration for legitimacy Courts have considered the applicant's reliance on the representation as a relevant consideration when determining the existence of a legitimate expectation. The role of reliance may be better assessed by distinguishing between "weak reliance" and "strong reliance". Weak reliance occurs when the applicant was made aware of and merely believed in the truth of the representation. Strong reliance, on the other hand, occurs where the applicant acted upon the representation and consequently faced detriment. Weak reliance is not required where the authority failed to apply the general policy at the time to the individual case at
