Unless the treaty provides otherwise, a State or an international organization may not formulate a reservation to a treaty after expressing its consent to be bound by the treaty except if none of the other Contracting Parties objects to the late formulation of the reservation.
除非条约另有规定，一国或一国际组织不得在表示同意受条约约束后提出保留，但其他缔约方不反对过时提出保留者除外。
