Research fellow Arron N Honniball was invited to sit on the Committee of Appointed Judges for the inaugural Netherlands Institute for the Law of the Sea (NILOS) Moot Court Competition, which was organised by Utrecht University. This competition is the first moot court that simulates proceedings under Part XV of the United Nations Convention on the Law of the Sea. Judges graded the memorials submitted by the teams, which pleaded the Case Concerning Certain Activities in the DeGroot Sea before ITLOS. The final rounds of the competition took place on 22–24 May 2019.
