 Rawls’ conception of political legitimacy can also be understood in terms of procedural reasons (Peter 2008). On this interpretation, the domain of public reason is limited to the justification of the process of political decision-making, and need not extend to the substantive (as opposed to the procedural) reasons people might hold to justify a decision. For example, if the hypothetical consensus supports democratic decision-making, then the justification for a decision is that it has been made democratically. Of course, a political decision that is legitimate in virtue of the procedure in which it has been made may not be fully just. But this is just a reflection of the fact that legitimacy is a weaker idea than justice.
