The corruption of public officials and institutions is generally regarded as wrong. But in what exactly does this form of corruption consist and what kind of wrong does it imply? Recent proponents of the “institutionalist approach” to political corruption have concentrated on those occasions when incentive structures distract institutions from their essential purpose and weaken public trust. The corruption of individual public officials has been less relevant to their work, except for when it leads to the erosion of the functioning (...) of institutions. From this perspective, a clear emphasis has been put on the consequences of corruption. In contrast, I argue that political corruption, whether individual or institutional, can be more fundamentally understood as a form of political injustice in which someone has violated the logic of mutual accountability that undergirds all relations of justice in rights-based systems. In this sense, political corruption occurs when public officials use their entrusted power of office for the pursuit of an agenda whose rationale may not be vindicated as coherent with the terms of their mandate. By focusing on the inherent qualities of corrupt political relations, I lay out a novel relational and deontological understanding of the inherent wrongness of political corruption as a form of unaccountable action.
