Travelling to Washington to compete in the world's largest moot court competition, the Sydney University law students fought it out in a final round against Ivy League school Columbia University.

With participants from over 500 law schools in more than 80 countries, the competition involved a simulation of a fictional dispute between countries before the International Court of Justice, addressing international anti-corruption law and the legality of the use of unmanned drones.

The winning team of five final-year students comprised Patrick Bateman, Chris Beshara, Glenn Kembrey, Chelsea Tabart and Patrick Wall.

"This is an outstanding achievement demonstrating how talented and dedicated to excellence our students are," said Professor Gillian Triggs, the dean of Sydney Law School.

"I would also like to recognise the moot judges from the legal profession and among our faculty who have given many hours to the practice moots over the last few weeks and to mastering the complex law and facts raised by the problem."
