It is essential to have opportunities to correct and intervene in policies, not only to ensure that development will fulfil basic needs, but also that it will achieve its critical transformative value. In both instances, vested interests may impose policies on people who are perceived as powerless. Human rights offer a framework for challenging these trends, as they provide legal protection of human dignity, and development processes must be undertaken in a context of accountability in order that those living in disadvantaged and vulnerable positions do not face negative impacts as a result.
