To cite a multilateral convention, Rule 21.4.5(a)(ii) of The Bluebook: A Uniform System of Citation, 20th ed., requires a U.S. source, if therein, with an optional parallel citation to a multilateral source. If neither of those can be obtained, Rule 21.4.5(c) requires a cite to I.L.M. or another unofficial source. Rule 21.11(d) has examples for some WTO and former GATT-era agreements.
NOTE: Bluebook rules can change, so please check the latest edition at the time of your writing.
The suggested citations below do not contain any U.S. treaty sources because the U.S. did not ratify the Uruguay Round agreements as treaties, but instead implemented them through legislation and administrative action. See Citing official U.S. sources.
Instead, the citations below use U.N.T.S. and I.L.M. To locate U.N.T.S. see here and I.L.M. here. Unlike the United Nations, there is no separate GATT or WTO treaty series.
In less recent publications, you may also see a citation to a WTO publication called The Legal Texts: The Results of the Uruguay Round of Multilateral Trade Negotiations (Cambridge, U.K.; New York, N.Y.: Cambridge University Press, [2010] 1999) Reserve K4600.A35 R473 2010.
