The Australian Jessup Moot controversy of 2013 was a series of events affecting the results of the Australian round of the Philip C. Jessup International Law Moot Court Competition. The incident involved a series of scoring errors which resulted in erroneous seeding of teams and erroneous determinations about which teams had progressed throughout the Competition. As a result, the international administrator of the competition, ILSA, determined that four Australian teams rather than the usual two teams would compete in the international round in Washington, DC.
