Equality duties are particular in that they have an effect beyond prohibiting discrimination, since they are geared towards preventing discrimination. Therefore agencies and institutions with public functions must, in everything they do - that is in their decision making processes, development of measures, budgeting, procurement, provision of services and employment - actively search for ways in which they may achieve greater equality of opportunity and better interaction in order to prevent discrimination. Authorities are especially obliged to respect the needs of discriminated individuals when a measure has differing effects on various groups of people.
