1) A state may incur international liability if it violates customary international law or treaty obligations. For a state to be responsible, the wrongful conduct must be attributable to the state and constitute a breach of an international legal obligation.
2) For conduct to be attributable to a state, it must be committed by a state organ or entity exercising governmental authority. Conduct of private individuals may also be attributable if carried out under the instruction or direction and control of the state.
3) Before responsibility can be invoked, local remedies within the responsible state must generally be exhausted, except in situations where remedies are ineffective, futile, biased, or waived.
