This is how you cite the US Constitution:
U.S. Constitution. Amend. XII, Sec. 3
Using the above as an example I would cite Universal Declaration of Human Rights as
U.N. Universal Declaration of Human Rights. Art. 26, Sec. 1
In text (U. N. Universal Dec. art. 26, sec. 1)
According to the Owl at Purdue, you might also reference the U.S. Constitution (or United Nations Universal Declaration of Human Rights) in the sentence itself and only provide the amendment (article) and section number in the parentheses at the end of the sentence.
