 Once institutions are established for the purpose (among other things) of delivering justice on a large scale, we can ask what duties of justice individual people have in consequence. Is their duty simply to support the institutions, and comply with whatever rules of conduct apply to them personally? Or do they have further duties to promote justice by acting directly on the relevant principles in their daily lives? No one doubts that some duties of justice fall directly on individuals, for example duties not to deceive or defraud when engaging in commercial transactions (and duties of corrective justice where behaviour is faulty), or duties to carry out one’s fair share of an informally organized project from which one expects to benefit, such as cleaning up the neighbourhood park. Others fall on them because they are performing a role within a social institution, for example the duty of an employer not to discriminate on grounds of race or gender when hiring workers, or the duty of a local government officer to assign public housing to those in greatest need. But what is much more in dispute is whether individual people have more extensive duties to promote social justice (for contrasting views, see Cohen 2008, ch. 3, Murphy 1998, Rawls 1993, Lecture VII, Young 2011, ch. 2).
