In August each year, selected scholars of space law produce the Manfred Lachs Space Law Moot Court problem for the following year, released to universities and posted on this website. Law schools in each region then register for the Regional Rounds and submit written memorials on the moot problem in February. Regional Rounds are held between March and May, with the Asia-Pacific Regional Round usually held in Sydney, Australia, the North America Regional Round in Washington, D.C., and the European Regional Round hosted in various cities.

The winner of each region then gather for the world finals in October, held in conjunction with the International Astronautical Congress and the IISL Colloquium on the Law of Outer Space.

The 2011 Manfred Lachs Space Law Moot Court Competition problem has now been issued and is available at: http://www.iislweb.org/docs/2011problem.pdf.
