The competition is based on a hypothetical space law dispute before the International Court of Justice. The 2013 problem concerned issues regarding the establishment and use of a lunar facility, unilateral imposition of national environmental laws to protect the Moon, refusal to allow the docking at a lunar facility by a manned spacecraft (potentially in distress) and liability for the failure in the deployment of scientific space probes. Students need not only know the case they are presented with well, but also need to have a solid grounding in the relevant space and international laws, be able to think and argue orally in front of experts and need to have the necessary research and writing skills to prepare written arguments for competition purposes.

The TuksLaw team was one of the four international teams that progressed to the semi-finals, where they they were eliminated in a closely contested round against the team that went on to win the World Championships – Georgetown University, Washington D.C., USA.
