Conceptually, this article links the closures of the dispute to its possible reopening. The first link modalities of closures to the situation of disputes. Each situation involves a network of potential closures. In our case, we propose three situations: a) a corporate dispute (1987-1989), b) a parliamentary dispute (1992-1994) and c) a dispute on the street (1997-1999). They point out that closing procedures corresponding to each contention situation. The second analysis is aimed at reopening of disputes, provided that they are linked intimately to the last closure. At one point, the closure of the conflict provides a broad spectrum of competence/incompetence of collectifs and visibility/invisibility of devices. This state of appeasement at the time of reopening, serves as a map of the conflict and can use this distribution of collectifs and devices as the key to analysis of future disputes.
