This contribution describes the International Law Commission’s Draft Articles of 2011 on the Effect of Armed Conflicts on Treaties. The Articles in question begin by defining the notion of “armed conflicts” which, in the commission’s view should include internal armed conflicts, at least if there is outside participation. The Commission takes the contemporary view that extinction and even suspension is no longer the rule, it defines the factors to be used to decide on the survival, termination, or suspension of conventions, and it lists types of treaties that tend to survive. The contribution stresses that treaties do not necessarily survive—or lapse—en bloc. It also comments on a number of provisions to ensure that the Draft Articles will not affect the system of collective security embodied in the Charter of the United Nations.
