In this essay, I discuss the merits of contestability in contrast with consent as a meansof legitimizing the state. Particularly I have been concerned with problematiccontracts: Contracts with undefined obligations and their implications on thelegitimacy of voluntarist consent. Through my argumentation, I have shown thatvoluntarist consent to political mandates has a hard time legitimizing politicalauthority in the presence of problematic contracts – and instead, that legitimationbased on the the ability to contest decisions may provide a better degree of politicallegitimacy. Contestability can seemingly also be combined with elements of voluntaristconsent to further cement the legitimacy of decisions.
