Supplementary means of interpretation
Recourse may be had to supplementary means of interpretation, including the preparatory work of
the treaty and the circumstances of its conclusion, in order to confirm the meaning resulting from the
application of article 31, or to determine the meaning when the interpretation according to article 31:
(a)
leaves the meaning ambiguous or obscure; or
(b)
leads to a result which is manifestly absurd or unreasonable.
