No one party to a treaty can impose its particular interpretation of the treaty upon the other parties. <answer>Consent</answer> may be implied, however, if the other parties fail to explicitly disavow that initially unilateral interpretation, particularly if that state has acted upon its view of the treaty without complaint. <answer>Consent</answer> by all parties to the treaty to a particular interpretation has the legal effect of adding another clause to the treaty – this is commonly called an 'authentic interpretation'.
