One part of building a new constitution after wars, revolutions, civil wars, or dramatic regime changes is to draw a cultural boundary in time, declaring various aspects of the old regime illegitimate and various legalities and constitutional principles of the new regime legitimate. One part of that process, in turn, is to decide how the new regime should treat the guilt of individuals for terror, collaboration, betrayal of information to the regime, and the like. This essay argues that such lustration processes should be a very minor part of the definition of the meaning of the pat, and even less of a part of building social supports under the new constitution. It also assesses the contributions on lustration in this issue in light of this view of what place lustration should play in the construction of democratic constitutions after authoritarian regimes.
